Abstract: This trial assessed if written information on procedural findings and subsequent treatment improved understanding and reduced anxiety among patients undergoing day case flexible cystoscopy (FC). Participants completed pre- and post-procedure questionnaires self-rating anxiety and feeling well informed on 5-point Likert scales. Supplemental written information was provided after FC to half the patients on a standardized template, according to randomized allocation. Comparisons between the groups were undertaken using the Wilcoxon test. Two hundred patients were recruited, with 171 evaluable questionnaires (83 from written group). The distribution of age, sex and prior FC, as well as the pre-procedure self-assessment of anxiety and understanding, was similar between the two groups. Patients receiving written information reported feeling better informed, with median (range) Likert score of 5 (4-5) compared to 4 (1-5) out of 5 (p < 0.0001) and less anxious (score 1 [1-4] compared to 2 [1-5] out of 5, p < 0.005), although all except four patients had an accurate understanding of the information provided (p = NS). Written information at the time of FC leads to patients feeling better informed and less anxious, although verbal information alone appears to lead to an adequate understanding. ACTRN12616000288426.

Abstract: A 49-year-old woman presented to the emergency department acutely unwell. Initial investigations revealed hyperglycaemia, ketosis and an acute kidney injury precipitated by urosepsis. She was found to have a new diagnosis of diabetes mellitus (type 2) with a glycated haemoglobin (HbA1c) of 156 mmol/mol. CT imaging of the abdomen and pelvis revealed unilateral emphysematous pyelonephritis (EPN), radiologically classified as stage 3 severity with gas extending beyond the renal collecting system. Escherichia coli was grown on blood and urine cultures. This was sensitive to second-generation cephalosporin cefuroxime. The patient was managed with fluid resuscitation, intravenous antibiotics and renal system decompression with urinary catheter insertion. She was commenced on an intravenous insulin infusion for hyperglycaemic crisis. This case illustrates a rare presentation of hyperglycaemic crisis precipitated by EPN in a patient without a previously known diagnosis of diabetes, successfully treated with medical management alone. Close clinical and radiological follow-up was arranged to monitor the need for future nephrectomy.

Abstract: To evaluate the contemporary prevalence of urinary tract cancer (bladder cancer, upper tract urothelial cancer [UTUC] and renal cancer) in patients referred to secondary care with haematuria, adjusted for established patient risk markers and geographical variation. This was an international multicentre prospective observational study. We included patients aged ≥16 years, referred to secondary care with suspected urinary tract cancer. Patients with a known or previous urological malignancy were excluded. We estimated the prevalence of bladder cancer, UTUC, renal cancer and prostate cancer stratified by age, type of haematuria, sex, and smoking. We used a multivariable mixed‐effects logistic regression to adjust cancer prevalence for age, type of haematuria, sex, smoking, hospitals, and countries. Of the 11 059 patients assessed for eligibility, 10 896 were included from 110 hospitals across 26 countries. The overall adjusted cancer prevalence ( n = 2257) was 28.2% (95% confidence interval [CI] 22.3–34.1), bladder cancer ( n = 1951) 24.7% (95% CI 19.1–30.2), UTUC ( n = 128) 1.14% (95% CI 0.77–1.52), renal cancer ( n = 107) 1.05% (95% CI 0.80–1.29), and prostate cancer ( n = 124) 1.75% (95% CI 1.32–2.18). The odds ratios for patient risk markers in the model for all cancers were: age 1.04 (95% CI 1.03–1.05 P 0.001), visible haematuria 3.47 (95% CI 2.90–4.15 P 0.001), male sex 1.30 (95% CI 1.14–1.50 P 0.001), and smoking 2.70 (95% CI 2.30–3.18 P 0.001). A better understanding of cancer prevalence across an international population is required to inform clinical guidelines. We are the first to report urinary tract cancer prevalence across an international population in patients referred to secondary care, adjusted for patient risk markers and geographical variation. Bladder cancer was the most prevalent disease. Visible haematuria was the strongest predictor for urinary tract cancer.

Abstract: We aimed to compare infection rates for two 3-day antibiotic prophylaxis regimens for transrectal ultrasound-guided prostate biopsy (TRUSgbp) and demonstrate local microbiological trends. In 2008, 558 men and, in 2009, 625 men had TRUSgpb. Regimen 1 (2008) comprised 400 mg Ofloxacin immediately before biopsy and 200 mg 12-hourly for 3 days. Regimen 2 (2009) comprised Ofloxacin 200 mg 12-hourly for 3 days commencing 24 hours before biopsy. 20/558 (3.6%) men had febrile episodes with regimen 1 and 10/625 (1.6%) men with regimen 2 (). E. coli was the most frequently isolated organism. Overall, 7/13 (54%) of positive urine cultures were quinolone resistant and (5/13) 40% were multidrug resistant. Overall, 5/9 (56%) patients with septicaemia were quinolone resistant. All patients were sensitive to Meropenem. There was 1 (0.2%) death with regimen 1. Commencing Ofloxacin 24 hours before TRUSgpb reduced the incidence of febrile episodes significantly. We observed the emergence of quinolone and multidrug-resistant E. coli . Meropenem should be considered for unresolving sepsis.

Abstract: The diagnostic evaluation of a PSA recurrence after RP in the Irish hospital setting involves multimodality imaging with MRI, CT, and bone scanning, despite the low diagnostic yield from imaging at low PSA levels. We aim to investigate the value of multimodality imaging in PC patients after RP with a PSA recurrence. Forty-eight patients with a PSA recurrence after RP who underwent multimodality imaging were evaluated. Demographic data, postoperative PSA levels, and imaging studies performed at those levels were evaluated. Eight (21%) MRIs, 6 (33%) CTs, and 4 (9%) bone scans had PCa-specific findings. Three (12%) patients had a positive MRI with a PSA <1.0 ng/ml, while 5 (56%) were positive at PSA ≥1.1 ng/ml (p = 0.05). Zero patient had a positive CT TAP at a PSA level <1.0 ng/ml, while 5 (56%) were positive at levels ≥1.1 ng/ml (p = 0.03). Zero patient had a positive bone at PSA levels <1.0 ng/ml, while 4 (27%) were positive at levels ≥1.1 ng/ml (p = 0.01). The diagnostic yield from multimodality imaging, and isotope bone scanning in particular, in PSA levels <1.0 ng/ml, is low. There is a statistically significant increase in the frequency of positive findings on CT and bone scanning at PSA levels ≥1.1 ng/ml. MRI alone is of investigative value at PSA <1.0 ng/ml. The indication for CT, MRI, or isotope bone scanning should be carefully correlated with the clinical question and how it will affect further management.

Abstract: Objective . To investigate the effects of height, external pressure, and bladder fullness on the flow rate in continuous, non-continuous cystoscopy and the automated irrigation fluid pumping system (AIFPS). Materials . Each experiment had two 2-litre 0.9% saline bags connected to a continuous, non-continuous cystoscope or AIFPS via irrigation tubing. Other equipment included height-adjustable drip poles, uroflowmetry devices, and model bladders. Methods . In Experiment 1, saline bags were elevated to measure the increment in flow rate. In Experiment 2, saline bags were placed under external pressures to evaluate the effect on flow rate. In Experiment 3, flow rate changes in response to variable bladder fullness were measured. Results . Elevating saline bags caused an increase in flow rates, however the increment slowed down beyond a height of 80 cm. Increase in external pressure on saline bags elevated flow rates, but inconsistently. A fuller bladder led to a decrease in flow rates. In all experiments, the AIFPS posted consistent flow rates. Conclusions . Traditional irrigation systems were susceptible to changes in height of irrigation solution, external pressure application, and bladder fullness thus creating inconsistent flow rates. The AIFPS produced consistent flow rates and was not affected by any of the factors investigated in the study.

Abstract: Data assessing the effectiveness of single-use flexible ureteropyeloscopy (FURS) are limited. This study evaluates and compares single-use FURS with conventional reusable FURS. A systematic search using electronic databases (Pubmed and Embase) was performed for studies evaluating single-use FURS in the setting of urinary tract stone disease. Outcome measures included a comparative evaluation of their mechanical, optical and clinical outcomes. Eleven studies on 466 patients met inclusion criteria. In vitro comparative data were available on three single-use flexible ureteropyeloscopes (LithoVue™, Polyscope™ and SemiFlex™) and clinical data were available on two (LithoVue™ and Polyscope™). The overall stone-free rate and complication rate associated with single-use FURS was 87 ± 15% and 9.3 ± 9%, respectively. There were no significant differences in procedure duration, stone size, stone clearance and complication rates when single-use FURS and reusable FURS were compared (duration: 73 ± 27 versus 74 ± 13 min, p = 0.99 stone size: 1.36 ± 0.2 versus 1.34 ± 0.18 cm, p = 0.93 stone-free rate: 77.8 ± 18 versus 68.5 ± 33%, p = 0.76 complication rate 15.3 ± 10.6 versus 15 ± 1.6%, p = 0.3). Single-use FURS demonstrates comparable efficacy with reusable FURS in treating renal calculi. Further studies on clinical efficacy and cost are needed to determine whether single-use FURS will reliably replace its reusable counterpart.

Abstract: Undergraduate training in core urology skills is lacking in many Irish training programmes. Our aim was to assess newly qualified doctors' experience and confidence with core urological competencies. A questionnaire survey covering exposure to urology and confidence with core clinical skills was circulated to all candidates. The group then attended a skills course covering male/female catheterisation, insertion of three-way catheters, bladder irrigation and management of long-term suprapubic catheters. The groups were re-surveyed following the course. Forty-five interns completed the pre-course questionnaire (group 1) and 27 interns completed the post-course questionnaire (group 2). 24/45 (53%) had no experience of catheter insertion on a patient during their undergraduate training. 26/45 (58%) were unsupervised during their first catheter insertion. 12/45 (27%) had inserted a female catheter. 18/45 (40%) had inserted a three-way catheter. 12/45 (27%) had changed a suprapubic catheter. 40/45 (89%) in group 1 reported 'good' or 'excellent' confidence with male urinary catheterisation, compared to 25/27 (92.5%) in group 2. 18/45 (40%) in group 1 reported 'none' or 'poor' confidence with female catheterisation, compared to 7/27 (26%) in group 2. 22/45 (49%) in group 1 reported 'none' or 'poor' confidence with insertion of three-way catheters, compared to 2/27 (7%) in group 2. 32/45 (71%) in group 1 reported 'none' or 'poor' confidence in changing long-term suprapubic catheters, falling to 3/27 (11%) in group 2. This study raises concerns about newly qualified doctors' practical experience in urology. We suggest that this course improves knowledge and confidence with practical urology skills and should be incorporated into intern induction.

Abstract: Introduction: Data comparing the incidence of ureteroenteric strictures for Bricker and Wallace anastomoses are limited. This study compares both anastomotic techniques in terms of ureteroenteric stricture rates after radical cystectomy and ileal conduit urinary ersion.Methods: Electronic databases (Medline, EMBASE, and Cochrane database) were searched for studies comparing Bricker and Wallace ureteroeneteric anastomoses for ileal conduit urinary ersion after radical cystectomy. Meta-analyses were performed using the random effects method. The primary outcome measure was to determine differences in postoperative ureteroenteric stricture rates for both surgical techniques. Four studies describing 658 patients met the inclusion criteria. The total number of ureters used for ureteroeneteric anastomoses was 1217 (545 in the Bricker group and 672 in the Wallace group).Results: There were no significant differences in age (p = 0.472), gender (p = 0.897), duration of follow-up (p = 0.168), and duration to stricture development between groups (p = 0.439). The overall stricture rate was 29 of 1217 (2.4%) 16 of 545 ureters (2.9%) in the Bricker group and 13 of 672 ureters (1.9%) in the Wallace group. The Bricker anastomosis was not associated with a significantly higher overall stricture rate compared to the Wallace ureteroenteric anastomosis (odds ratio: 1.393, 95% confidence interval: 0.441–4.394, p = 0.572).Conclusion: Accepting limitations in the available data, we found no significant difference in the incidence of ureteroenteric stricture for Bricker and Wallace anastomoses.

Abstract: Various types of ureteric stents are used in the management of ureteric stones. Stents on strings (SOS) are an attractive option as they may be removed without the need for instrumentation. There is some hesitation using SOS due to perceived complications and the risk of premature dislodgement. The aim of this study was to evaluate the utility of SOS compared with the conventional stent (CS). A retrospective review was performed on all ureteric stents removed in the urology department over a 7-month period. Only stents inserted during the endoscopic management of ureteric stones were included in analysis. Patients were contacted to identify the incidence of those seeking medical attention while the stent was in situ or within 2 weeks of stent removal. A basic cost analysis was performed. One hundred and sixty cases were identified (98 CS, 62 SOS). No SOS was dislodged prematurely. One SOS was removed cystoscopically due to a broken string. There was no significant difference in the number of patients with SOS seeking medical attention following stent placement compared with those with CS (38.1% (12/51) vs 25.6% (22/86), p = 0.48). There was an estimated cost saving of €23,790 associated with the use of SOS during the study period (€390/case). The use of SOS created additional capacity which was utilised for diagnostic cystoscopy. The SOS appeared to be well tolerated and showed similar complication rates as the CS. The use of SOS resulted in a significant cost saving and increased the availability of cystoscopy for other indications.

Abstract: Interactions between circulating tumour cells (CTCs) and platelets are thought to inhibit natural killer(NK)-cell-induced lysis. We attempted to correlate CTC numbers in men with advanced prostate cancer with platelet counts and circulating lymphocyte numbers. Sixty-one ExPeCT trial participants, ided into overweight/obese and normal weight groups on the basis of a BMI ≥ 25 or , were randomized to participate or not in a six-month exercise programme. Blood s les at randomization, and at three and six months, were subjected to ScreenCell filtration, circulating platelet counts were obtained, and flow cytometry was performed on a subset of s les (n = 29). CTC count positively correlated with absolute total lymphocyte count (r2 = 0.1709, p = 0.0258) and NK-cell count (r2 = 0.49, p 0.0001). There was also a positive correlation between platelet count and CTC count (r2 = 0.094, p = 0.0001). Correlation was also demonstrated within the overweight/obese group (n = 123, p 0.0001), the non-exercise group (n = 79, p = 0.001) and blood draw s les lacking platelet cloaking (n = 128, p 0.0001). By flow cytometry, blood s les from the exercise group (n = 15) had a higher proportion of CD3+ T-lymphocytes (p = 0.0003) and lower proportions of B-lymphocytes (p = 0.0264) and NK-cells (p = 0.015) than the non-exercise group (n = 14). These findings suggest that CTCs engage in complex interactions with the coagulation cascade and innate immune system during intravascular transit, and they present an attractive target for directed therapy at a vulnerable stage in metastasis.

Abstract: Introduction: The incidence of iatrogenic urethral catheterization (UC) injuries is approximately 0.3%. Resultant complications are associated with patient morbidity and unnecessary healthcare costs. Our aim was to investigate whether educational training workshops decreased the incidence of UC-related injuries.Methods: A prospective audit was performed to calculate incidence, morbidity, and costs associated with iatrogenic UC injury from January to July 2015. Educational workshops were then conducted with healthcare staff and training modules for junior doctors. UC-related incidence, morbidity, and costs in the subsequent six-month period were recorded prospectively and compared with the previous data.Results: The incidence of iatrogenic UC injuries was reduced from 4.3/1000 catheters inserted to 3.8/1000 catheters after the intervention (p=0.59). Morbidity from UC increased in the second half in the form of increase in cumulative additional inpatient hospital stay (22 to 79 days p=0.25), incidence of urosepsis (n=2 to n=4), and need for operative intervention (n=1 to n=2). The cost of managing UC injuries almost doubled in the period after the training intervention (€50 449 to €90 100).Conclusions: Current forms of educational and training interventions for UC did not significantly change morbidity or cost of iatrogenic UC injuries despite a decrease in incidence. Improved and intensive training protocols are necessary for UC to prevent avoidable iatrogenic complications, as well as a safer urethral catheter design.

Abstract: Introduction . The prevalence of obesity is increasing worldwide. Obesity can be determined by body mass index (BMI) however waist circumference (WC) is a better measure of central obesity. This study evaluates the outcome of laparoscopic nephrectomy on patients with an abnormal WC. Methods . A WC of cm for women and cm for men was defined as obese. Data collected included age, gender, American Society of Anaesthesiologists (ASA) score, renal function, anaesthetic duration, surgery duration, blood loss, complications, and duration of hospital stay. Results . 144 patients were assessed 73 (50.7%) of the patients had abnormal WC for their gender. There was no difference between the groups for conversion to open surgery, number of ports used, blood loss, and complications. Abnormal WC was associated with a longer median anaesthetic duration, 233 min, IQR (215–265) versus 204 min, IQR (190–210), p = 0.0022 , and operative duration, 178 min, IQR (160–190) versus 137 min, IQR (128–162), p 0.0001 . Patients with an abnormal WC also had a longer inpatient stay, p = 0.0436 . Conclusion . Laparoscopic nephrectomy is safe in obese patients. However, obese patients should be informed that their obesity prolongs the anaesthetic duration and duration of the surgery and is associated with a prolonged recovery.

Abstract: To examine the success rate of electroejaculatory stimulation in patients with acquired spinal injuries in a single Irish institution. The use of electroejaculatory stimulation is of benefit in patients with spinal cord injury who wish to have children. A retrospective review of the Hospital In-Patient Enquiry scheme database and the patients' medical notes was performed. Any patient who had undergone electroejaculatory stimulation in the past 14 years was included. The quality of semen obtained and the pregnancy rate were assessed in relation to several variables, including patient age and level of spinal injury. From 1994 to 2008, 31 patients (29 patients with acquired spinal injury and 2 patients with a congenital spinal abnormality) had undergone electroejaculatory stimulation as a method of providing semen for assisted conception. Of the 31 patients, 6 had requested cryopreservation of their semen for future use and were therefore excluded from the pregnancy rate analysis. Of the 25 patients who had used the semen, 9 (36%) were successful in achieving pregnancy that resulted in living offspring. The semen analysis results were available for 15 patients. Three patients (one each with contaminated semen, poor semen quality, and an abandoned procedure) required testicular biopsy to extract viable sperm and subsequently achieved pregnancy. Lower spinal lesions (below T10) were associated with lower rates of pregnancy after electroejaculatory stimulation. One patient developed autonomic dysreflexia during the procedure, which was therefore abandoned. Electroejaculatory stimulation is an effective method of obtaining semen for reproductive purposes and is an option for fertility preservation in patients with spinal cord injury-related anejaculation.

Abstract: To systematically review the literature to ascertain the upper tract pressures generated during endourology, the relevant influencing variables and clinical implications. A systematic review of the MEDLINE, Scopus and Cochrane databases was performed by two authors independently (S.C., N.D.). Studies reporting ureteric or intrarenal pressures (IRP) during semi‐rigid ureteroscopy (URS)/flexible ureterorenoscopy (fURS) ercutaneous nephrolithotomy (PCNL)/miniaturized PCNL (mPCNL) in the period 1950–2021 were identified. Both in vitro and in vivo studies were considered for inclusion. Findings were independently screened for eligibility based on content, with disagreements resolved by author consensus. Data were assessed for bias and compiled based on predefined variables. Fifty‐two studies met the inclusion criteria. Mean IRP appeared to frequently exceed a previously proposed threshold of 40 cmH 2 O. Semi‐rigid URS with low‐pressure irrigation (gravity m) resulted in a wide mean IRP range (lowest reported 6.9 cmH 2 O, highest mean 149.5 ± 6.2 cmH 2 O animal models). The lowest mean observed with fURS without a ureteric access sheath (UAS) was 47.6 ± 4.1 cmH 2 O, with the maximum peak IRP being 557.4 cmH 2 O ( in vivo human data). UAS placement significantly reduced IRP during fURS, but did not guarantee pressure control with hand‐operated pump/syringe irrigation. Miniaturization of PCNL sheaths was associated with increased IRP however, a wide mean human IRP range has been recorded with both mPCNL (lowest −6.8 ± 2.2 cmH 2 O [suction sheath] highest 41.2 ± 5.3 cmH 2 O) and standard PCNL (lowest 6.5 cmH 2 O highest 41.2 cmH 2 O). Use of continuous suction in mPCNL results in greater control of mean IRP, although short pressure peaks cmH 2 O are not entirely prevented. Definitive conclusions are limited by heterogeneity in study design and results. Postoperative pain and pyrexia may be correlated with increased IRP, however, few in vivo studies correlate clinical outcome with measured IRP. Intrarenal pressure generated during upper tract endoscopy often exceeds 40 cmH 2 O. IRP is multifactorial in origin, with contributory variables discussed. Larger prospective human in vivo studies are required to further our understanding of IRP thresholds and clinical sequelae.

Abstract: The Notch pathway is a highly conserved pathway increasingly implicated with the progression of human cancers. Of the four existing receptors associated with the pathway, the deregulation in the expression of the Notch-3 receptor is associated with more aggressive disease and poor prognosis. Selective targeting of this receptor has the potential to enhance current anti-cancer treatments. Molecular profiling strategies are increasingly incorporated into clinical decision making. This review aims to evaluate the clinical potential of Notch-3 within this new era of personalised medicine.

Abstract: 'TikTok' is a social media application based on the publication of short videos that has accumulated over 1.1 billion users worldwide since its launch in 2016. With the use of 'TikTok' on the rise, there is an increasing tendency for patients or family members to seek medical information online. We aim to assess the authenticity of information being spread on 'TikTok' on common paediatric urological presentations by comparison to current up to date guidelines provided by the European Association of Urology (EAU). A search for a variety of paediatric urology conditions was performed on 'TikTok'. Videos were subsequently screened based on strict pre-defined criteria. The content and claims of each video were compared to up-to-date guidelines to reveal whether or not they complied with standards set by the European Association of Urology (EAU). Information that correlated with that of the guidelines was then further classified by Oxford levels of evidence. 27 videos met our criteria with a combined total of 6,578,863 views, 308,700 likes and 5782 comments. Only 22.2% of videos contained information that can also be found in guidelines provided by the EAU. None of the included videos contained any cited evidence to reinforce statements that were being made. Misinformation lacking scientific evidence has been reported has been reported for various conditions on 'TikTok'. Patients, family members or caregivers without a medical background can have difficult verifying and ensuring the credibility of information posted on social media. The evolution of 'TikTok' has allowed the layperson to create content that can potentially reach millions of users worldwide. This study demonstrated that 'TikTok' can be used as a resource for health information, however is currently a pit of misinformation with the potential to cause harm to the user.

Abstract: To report the incidence of genitourinary (GU) injuries in pelvic and acetabular (P + A) fractures, to investigate associations between P + A fractures and GU injury patterns, and, as a secondary objective, to evaluate prospectively P + A fracture referrals with regard to adherence to the British Orthopaedic Association Standards for Trauma (BOAST) guidelines over a 12-month period. A retrospective review of GU injuries associated with P + A fractures was performed for the period January 2006 to December 2016 in a national pelvic trauma centre in Ireland. Patient demographics, mechanism of injury and details of injuries were recorded. In addition, P + A fracture referrals were prospectively monitored in 2016 and reviewed for adherence to guidelines. The incidence of urological trauma in P + A fractures was 2.4% (n = 28/1 141). The median (range) patient age was 45 (19-85) years and the male to female ratio was 2.1:1. Urethral injuries occurred most frequently (n = 12, 43%), followed by bladder (n = 9, 32%), combined bladder and urethral (n = 3, 11%) and kidney (n = 4, 14%). Bladder and urethral injuries were associated with high-energy pelvic trauma. Renal injuries were associated with acetabular fractures in isolation and in combination with pelvic trauma (P = 0.01). In 2016, there were 175 P + A fracture referrals and 19 patients had suspected urotrauma (visible haematuria, n = 5 non-visible haematuria, n = 2 trauma imaging, n = 11) 9 of these 19 patients had no urological investigations performed. In P + A trauma cases GU injuries may be underreported because of inadequate evaluation and diagnostic investigations in these patients. We advocate robust, uniform and guideline-based evaluation of GU injuries in P + A trauma to avoid the significant long-term morbidities that are associated with misdiagnosis.

Abstract: Noncontrast CT (NCCT) has become the standard Imaging study in the emergency department (ED) diagnosis of nephro- and ureterolithiasis. We undertook to audit the results from the first 500 NCCTs performed for patients presenting to the ED with suspected renal colic. In a retrospective study at one institution from October 2003 to February 2006, 500 patients with suspected stone disease were investigated. In the study, NCCT findings, patient clinical records, and urinary microscopy results were evaluated for 166 women and 334 men. Renal or ureteral calculi were identified in 279 (56%) of NCCTs performed. Of the 500, 112 (19%) NCCTs performed identified unexpected intra-abdominal pathology. When the findings deemed to be of low clinical significance were excluded, the number of scans with additional pathology amounted to 67 (13%). These included vascular emergencies, new cancer diagnoses, and gastrointestinal conditions. The variety of diagnoses found unexpectedly on the NCCT that alter a patient's treatment demonstrates the pivotal role of NCCT in the triage of these patients rapidly toward optimal therapy. The rapid acquisition time of NCCT has enabled definitive ED patient diagnosis and less bed occupancy for clinically insignificant calculi.

Abstract: Ruptured abdominal aortic aneurysm (RAAA) is a demanding vascular surgical problem and the cause of significant morbidity and mortality. The aim of this study was to identify prognostic factors that influence outcome. Over 6 years, 42 ruptured abdominal aortic aneurysms were operated on with a mean diameter of 7.2 cm. RAAA was defined as free intraperitoneal rupture. Data were collected retrospectively from hospital medical records. The male:female ratio was 8:1 and the mean age was 74 years (range 55–89). Fifteen were in hypovolemic shock and 27 patients were clinically stable. The perioperative mortality rate for the 15 shocked patients was 60% (9 patients) and the 1-year cumulative survival rate was 33%. The perioperative mortality rate for the 27 clinically stable patients was 40% (11 patients) and the 1-year cumulative survival rate was 56%. Survival curves were constructed for these groups to compare male versus female, age =70 versus age , shocked versus stable, and preoperative hemoglobin (Hb) =10 vs . No patient with preoperative cardiac arrest survived more than 24 hours. With VassarStats, the confidence interval for age, gender, hemodynamic status, and preoperative Hb were calculated. The standard weighted mean analysis by ANOVA gave a p value of .001. The overall 30-day mortality rate was 47% (20 of 42) and the 1-year mortality rate was 52% (22 of 42). Male patients over 70 years with RAAA in hypovolemic shock with low Hb have a higher 30-day mortality rate and few survive more than 1 year. The study suggests that each of these 4 parameters separately was not a strong prognostic indicator. Collectively, however, they strongly influence the prognosis of patients with RAAA. These findings strengthen the case for selective treatment for RAAA.

Abstract: Cranberry supplements are commonly used as a natural deterrent to urinary tract infection. However, one small study (n = 5) which showed an increase in urinary oxalate levels following cranberry supplementation has led to its use with caution among patients susceptible to nephrolithiasis. Furthermore, most commonly available cranberry tablet preparations contain vitamin C, which has been independently shown to increase urinary oxalate excretion. The aim of this study is to investigate the influence of cranberry supplementation on urinary oxalate excretion. Fifteen participants were randomised to receive cranberry tablets alone or cranberry tablets containing vitamin C. Tablets were taken at the manufacturers recommended dosage for a period of 14 days. Participants provided a 24 h urine collection at trial entry and day 14. Urinary variables were compared to assess for changes in oxalate levels. The median age was 27 years (21-43). There was no difference in the 24 h urine volume pre or post commencement of cranberry tablets (1.7 vs 2 L, p = 0.07). An increase in median urinary oxalate excretion was observed in participants taking both cranberry-only tablets (0.10 mmol/day) and tablets containing vitamin C (1.15 mmol/day). Dietary supplementation with cranberry increases urinary oxalate excretion and should be avoided in patients at risk of urolithiasis.

Abstract: Botulinum toxin A is effective for treatment of idiopathic detrusor overactivity (IDO). The trigone is generally spared because of the theoretical risk of vesicoureteric reflux (VUR), although studies assessing injection sites are lacking. Evaluate efficacy and safety of trigone-including versus trigone-sparing intradetrusor injections of abobotulinumtoxinA in patients with IDO. Twenty-two patients from one centre were randomised to trigone-including or trigone-sparing injections. Injection of 500 U abobotulinumtoxinA diluted to 20ml into 20 trigone-including or trigone-sparing sites. The primary outcome measure was total overactive bladder symptom score (OABSS) at 6 wk. The OABSS questionnaire was completed at 0, 6, 12, and 26 wk. Baseline and postinjection urodynamic studies and micturating cystourethrograms were performed. Baseline values and subsequent time points were compared by t test. A mixed-effect model was used for repeated measures in time. For symptom scores at baseline compared with scores at 6 wk postinjection, the mean total OABSS improved from 22.4 to 8.7 (p<0.001) in the trigone-including group compared with 22.7 to 13.4 (p<0.03) in the trigone-sparing group. The difference in mean change from baseline was 4.4 points in favour of the trigone-including group (p=0.03). The total OABSS at 12 and 26 wk and the urgency subscale scores at 6, 12, and 26 wk showed significant improvement in favour of the trigone-including group. Mean postvoid residual volumes and clean intermittent self-catheterisation rates between the two groups were similar. No patients developed VUR. Performing injections under general anaesthetic was a limitation, as tolerability under local anaesthetic was not assessed. A further limitation is the lack of a trigone-only arm. Trigone-including injections are superior to trigone-sparing injections for the treatment of refractory IDO and did not cause VUR in this study.

Abstract: With increasing surgeon experience, the use of laparoscopic radical nephrectomy (LRN) in large and locally advanced renal tumours (T3a) is gaining favour in urological practice. There are limited studies reporting surgical outcomes in such groups. The aim of this study was to review our experience with LRN in these patients. Data was retrospectively collected on 201 consecutive patients who underwent LRN for renal cancer by a single surgeon. Perioperative parameters assessed were age, gender, American Society of Anaesthesiologists score (ASA), waist circumference, tumour size, specimen size, histological subtypes, anaesthetic duration, operative approach and technique, surgery duration, blood loss, pre and postoperative renal function, complication rate and duration of hospital stay. Of 201 patients undergoing LRN, 43 (21%) patients had T3a tumours (group 2). The remaining 158 (79%) patients had T1 tumours (group1). Mean tumour size in group 2 was 12.2 cm. Renal cell carcinoma (RCC) was more common in males than females (131/201 65%). Patients with T3a disease were more likely to have an ASA score of 2 (37/201 18%). In the majority of patients across both groups, LRN was completed using a 3-port approach (173/201 86%). There were no significant differences between groups in terms of mean anaesthetic duration, average surgical time, average estimated blood loss, complication rate and mean hospital stay. Our study shows that LRN has equivalent perioperative outcomes and safety in larger and locally advanced renal tumours.

Abstract: Liquid biopsies that noninvasively detect molecular correlates of aggressive prostate cancer (PCa) could be used to triage patients, reducing the burdens of unnecessary invasive prostate biopsy and enabling early detection of high-risk disease. DNA hypermethylation is among the earliest and most frequent aberrations in PCa. We investigated the accuracy of a six-gene DNA methylation panel (Epigenetic Cancer of the Prostate Test in Urine [epiCaPture]) at detecting PCa, high-grade (Gleason score greater than or equal to 8) and high-risk (D’Amico and Cancer of the Prostate Risk Assessment] PCa from urine. Prognostic utility of epiCaPture genes was first validated in two independent prostate tissue cohorts. epiCaPture was assessed in a multicenter prospective study of 463 men undergoing prostate biopsy. epiCaPture was performed by quantitative methylation-specific polymerase chain reaction in DNA isolated from prebiopsy urine sediments and evaluated by receiver operating characteristic and decision curves (clinical benefit). The epiCaPture score was developed and validated on a two thirds training set to one third test set. Higher methylation of epiCaPture genes was significantly associated with increasing aggressiveness in PCa tissues. In urine, area under the receiver operating characteristic curve was 0.64, 0.86, and 0.83 for detecting PCa, high-grade PCa, and high-risk PCa, respectively. Decision curves revealed a net benefit across relevant threshold probabilities. Independent analysis of two epiCaPture genes in the same clinical cohort provided analytical validation. Parallel epiCaPture analysis in urine and matched biopsy cores showed added value of a liquid biopsy. epiCaPture is a urine DNA methylation test for high-risk PCa. Its tumor specificity out-performs that of prostate-specific antigen (greater than 3 ng/mL). Used as an adjunct to prostate-specific antigen, epiCaPture could aid patient stratification to determine need for biopsy.

Abstract: Ireland's population is living longer, and the prevalence of any LUTS is estimated to be 63-83% in adult men, increasing with age. Ireland has one of the lowest urologists per population ratio in Europe, at approximately 1:127,027. The patients waiting the longest are those with routine benign conditions such as men with LUTS. The impact on quality of life for men experiencing LUTS can be profound. Sláintecare funded an ANP post in TUH to develop an integrated referral pathway for male LUTS and develop a secondary care nurse-led clinic for LUTS and tackle the ever increasing new and return waiting lists. The initial focus of this role was on reducing pre-existing outpatient (OP) waiting lists. This is a review of the first 12-month outcomes of this ANP post. A total of 410 new patients were assessed over the 12-month period. The mean waiting time from referral to review was 24 months however, some referrals dated back to 2014. Four hundred forty-two return patients were reviewed in the 12-month period. All these patients were waiting longer than 18 months for a return appointment. In absence of the ANP-led clinic, there was no capacity for any of these patients to be reviewed in the general urology clinics. Overall outcomes were as follows: 38% were given advice and education and discharged. Treatment was initiated in 42% and follow-up arranged. Physical review was deemed necessary for 11% of patients. Only 6% of patients reviewed required referral back to consultants' clinic. This study demonstrates the safety, efficacy and financial advantage of an ANP-led clinic for adult men presenting with lower urinary tract symptoms previously triaged by a consultant urologist.

Abstract: Introduction: As both the number of cancer survivors and the length of survival time are increasing, long-term health issues related to cancer and its treatment are becoming more prevalent. Research suggests that exercise can mitigate several negative health consequences in cancer survivors and improve physical function and quality of life. Multi-modal exercise interventions have been proposed as a cornerstone for survivorship care. However, studies evaluating exercise programmes within the Irish population are lacking. Purpose: To evaluate the introduction, implementation and acceptability of a multi-modal exercise rehabilitation programme for deconditioned cancer survivors in a real-world, standard practice setting. Methods and analysis: In this single-arm prospective feasibility study, cancer survivors (n=40) will undergo a 10-week multi-modal exercise programme. The study population will comprise of cancer survivors attending outpatient services in an Irish national cancer centre. Participants will be aged 18 or older and have completed treatment with curative intent. Feasibility will be evaluated in terms of recruitment, adherence and compliance to the programme. Secondary outcomes will examine physical function and quality of life measures. In addition, the acceptability of the programme will be assessed through stakeholder feedback. Ethics and dissemination : Ethical approval through the St. James’s Hospital and Tallaght University Hospital Research and Ethics Committee is currently pending. The study results will be used to optimise the intervention content and may serve as the foundation for a larger definitive trial. Results will be disseminated through peer-review journals, congresses and relevant clinical groups. Trial registration : ClinicalTrials.gov NCT04026659 (19/07/19)

Abstract: To investigate the association between extravesical (18)F-fluorodeoxyglucose (FDG) avid lesions on FDG-positron emission tomography/computed tomography (PET/CT) and mortality in patients with muscle-invasive bladder cancer. An international, bi-institutional cohort study of 211 patients with muscle-invasive bladder cancer who underwent staging CT and FDG-PET/CT imaging. On the basis of the presence of extravesical FDG-avid lesions suspicious for malignancy on PET/CT images, patients were ided into a PET/CT-positive and PET/CT-negative group. Data on staging and mortality were retrospectively analyzed from prospective databases. Kaplan-Meier analyses were performed to compare overall (OS) and disease-specific survival (DSS) between the groups. Multivariable Cox regression models were used to investigate the association between extravesical PET/CT lesions and mortality. Extravesical lesions suspicious for malignancy on conventional CT were included in the models. Of the 211 patients, 98 (46.4%) had 1 or more extravesical lesions on PET/CT, 113 (53.5%) had a negative PET/CT. Conventional CT revealed extravesical lesions in 51 patients (24.4%). Median follow-up was 18 months. Patients with a positive PET/CT had a significantly shorter OS and DSS (median OS: 14 vs 50 months, P = .001 DSS: 16 vs 50 months, P <.001). In multivariable analysis, the presence of extravesical lesions on PET/CT was an independent prognostic indicator of mortality (OS: hazard ratio = 3.0, confidence interval 95% 1.7-5.1). This association was not statistically significant for conventional CT (hazard ratio = 1.6 (95% confidence interval 0.9-2.7). On the basis of our results, the presence of extravesical FDG-avid lesions on PET/CT might be considered an independent indicator of mortality.

Abstract: To assess whether a correlation exists between newsworthiness (Altmetric score) and scientific impact markers, such as citation analysis, impact factors, and levels of evidence. The top five most cited articles for the year 2014 and 2015 from the top 10 ranking urology journals (Scientific Impact Group) were identified. The top 50 articles each in 2014 and 2015 were identified from Altmetric support based on media activity (Media Impact Group). We determined the number of citations that these articles received in the scientific literature, and calculated correlations between citations with Altmetric scores. In the Scientific Impact Group, the mean number of citations per article was 37.6, and the most highly cited articles were oncology guidelines. The mean Altmetric score in these articles was 14.8. There was a weak positive correlation between citations and Altmetric score (r The top articles based on Altmetric scores were not highly cited, suggesting that publications receiving the most media attention may not be the most scientifically rigorous, or that this audience places greater value on different subjects than the scientific community.

Abstract: We report the first case of a synchronous ipsilateral primitive neuroectodermal tumour (PNET) and clear cell renal cell carcinoma of the kidney. A 37-year-old man presented to the emergency department with a 24-hour history of colicky abdominal pain and visible haematuria. He had no relevant surgical or medical history. Physical examination was unremarkable apart from mild left flank tenderness. Triphasic CT of the abdomen and pelvis showed two solid lesions in the left kidney. Further staging CT of the chest showed no evidence of local or distal metastasis. He subsequently underwent laparoscopic radical nephrectomy. Pathological analysis of the kidney showed two synchronous renal tumours, a clear cell carcinoma and PNET of the kidney. The patient received adjuvant chemotherapy according to Ewing’s sarcoma chemotherapy protocol. Surveillance CT scans at 3, 6 and 12 months showed no evidence of disease recurrence or metastasis.

Abstract: The most appropriate management of incidental prostate cancers diagnosed at transurethral resection of prostate has been debated. It is important to determine the long-term outcomes to establish an appropriate management in patients with incidental prostate cancer. We aim to determine 10-year survival and to identify the factors of worse prognosis of incidental prostate cancers diagnosed at transurethral resection of prostate. A retrospective analysis of patients with pT1a-pT1b prostate cancers diagnosed between 1998 and 2003. Medical notes, PSA and pathology results were reviewed. Overall and cancer specific survival was calculated at mean 10-year follow-up. Sixty patients with incidental prostate cancer were identified (pT1a = 18, pT1b = 42). Fifty-one percents of the patients were managed on a watchful waiting strategy with overall 84% survival and 9.7% cancer specific mortality. Twenty patients (all with pT1b) received hormone therapy. Overall survival in this cohort was 50% with 20% cancer specific mortality. Nine patients received curative therapy (Radical prostatectomy = 4, Radiotherapy = 5). In this group, overall survival was 88% with no cancer specific mortality. Stage pT1a disease and preoperative low PSA were associated with favourable survival. However, for pT1b and/or high Gleason score (≥7), mortality was comparatively higher. Hence, patients with high Gleason score and/or pT1b disease should be considered for curative therapy. Additionally, active surveillance may have a role in selected men with incidental prostate cancer.

Abstract: Technique is vital to prevent urethral trauma during urethral catheterisation (UC). Education programmes are helpful but are not compulsory and safe UC remains operator dependent. Traumatic UC is associated with increased morbidity, length of stay, resource utilisation and surgical intervention. To determine the cost of iatrogenic urethral injuries managed in a tertiary referral centre over a 6-month period. A 6-month prospective study monitored iatrogenic urethral injuries secondary to traumatic UC. Included were referrals from district hospitals and inpatient consultations relating to urethral injury caused by traumatic UC. The added cost of management was estimated. Thirteen iatrogenic urethral injuries were recorded in 6 months. Management included open surgery for a ruptured bladder (n = 1), flexible cystourethroscopy (n = 10), suprapubic catherisation (n = 4), 3-way catheterisation (n = 4) and catheter re-insertion under direct vision (n = 6). The cost of acute management of these injuries was approximately €50,000 including theatre costs, ambulance transfer, hospital stay, procedural and equipment costs and short-term follow-up care. Iatrogenic injuries during UC represent a significant cost burden to the healthcare system. Training programmes should be compulsory for all healthcare professionals routinely involved in catheterisation procedures.

Abstract: SARS‐CoV‐2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri‐operative or prior SARS‐CoV‐2 were at further increased risk of venous thromboembolism. We conducted a planned sub‐study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS‐CoV‐2 diagnosis was defined as peri‐operative (7 days before to 30 days after surgery) recent (1–6 weeks before surgery) previous (≥7 weeks before surgery) or none. Information on prophylaxis regimens or pre‐operative anti‐coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS‐CoV‐2 2.2% (50/2317) in patients with peri‐operative SARS‐CoV‐2 1.6% (15/953) in patients with recent SARS‐CoV‐2 and 1.0% (11/1148) in patients with previous SARS‐CoV‐2. After adjustment for confounding factors, patients with peri‐operative (adjusted odds ratio 1.5 (95%CI 1.1–2.0)) and recent SARS‐CoV‐2 (1.9 (95%CI 1.2–3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS‐CoV‐2 (1.7 (95%CI 0.9–3.0)). Overall, venous thromboembolism was independently associated with 30‐day mortality (5.4 (95%CI 4.3–6.7)). In patients with SARS‐CoV‐2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri‐operative or recent SARS‐CoV‐2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS‐CoV‐2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

Abstract: Modification of antibiotic prophylaxis prior to transrectal ultrasound-guided prostate biopsy (TRUSPB) based on pre-procedure rectal culture results is effective for prevention of infection from fluoroquinolone (FQ)-resistant and extended-spectrum beta-lactamase (ESBL) Escherichia coli strains. This has several implications for service delivery and cost. Our aim was to audit sepsis rates after introduction of ESBL screening and to identify risk factors for FQ resistance in ESBL strains and factors for sepsis risk. This was a prospective cohort study from 2013 to 2016. TRUSPB patients underwent pre-procedure rectal swabs. ESBL-positive patients received amikacin in addition to ciprofloxacin prophylaxis. Patients filled a formal risk assessment questionnaire prior to biopsy. Sepsis rate after introduction of targeted prophylaxis reduced from 3.1% (2009-2012) to 1.4% (2013-2016). Of 38 ESBL patients, n = 5 (13%) developed severe post-TRUSPB sepsis. Among the FQ-resistant ESBL producers, the sepsis rate was 24%. Predictive factor for FQ resistance in ESBL producers included-antibiotic use in the last 3 months (OR 15). The logistic regression analysis did not identify any significant factor for post-TRUSPB sepsis in ESBL-positive patients once they had received additional prophylaxis. In the face of rising TRUSPB sepsis and higher sepsis rates with ESBL carriers despite additional prophylaxis, introduction of a targeted antibiotic prophylaxis prior to TRUSPB sepsis prostate biopsies based on rectal swabs or urine cultures may reduce sepsis rates or clinicians may find themselves leaning towards increasingly performing transperineal biopsies with lower sepsis rates supporting the 'trexit' initiative.

Abstract: To explore the perceptions of higher specialist trainees and fellows in Ireland with respect to the Irish Department of Health’s recent proposal to implement a drafted, non-negotiated, consultant contract under a new model for healthcare, termed the Sláintecare plan. A customized survey, incorporating multiple-choice and Likert-scale questions and a free-text option, was disseminated to doctors enrolled in Irish higher specialist training (HST) programmes and pre-consultant HST graduates (fellows). Responses were compiled and analysed. There were a total of 1109 respondents across all specialities. Trainees were particularly concerned regarding the Sláintecare contract’s potential impact on their abilities to engage in patient advocacy and provide optimal patient care in the future, the maintenance of specialist skillsets, their ownership of intellectual property and a stable location of the practice. Of respondents, 93.7% (1003/1070) indicated that they would consider working abroad rather than accept the proposed contract. This study highlights the perceptions and concerns of the higher specialist trainees and fellows of Ireland. A large proportion may emigrate rather than accept the Sláintecare proposals. Concerns exist surrounding the ability to advocate for patients, to provide patient care, the proposed working conditions and perceived potential to deskill under this contract’s terms.

Abstract: To quantify user variability and manufacturer variability in urinary catheter anchoring balloon inflation pressure and to mitigate any significant variance by incorporating flow resistance into the anchoring balloon inflation process. Inflation of a urinary catheter anchoring balloon was performed at atmospheric pressure by different users (n = 8) to investigate user variability. A calibrated pressure transducer measured inflation pressures, and a video extensometer measured balloon inflation profiles. Manufacturer variability was investigated by applying constant forces to the plunger of conventional syringes to mimic "heavy-," "intermediate-," and "light"-handed users for 3 brands of catheter. Flow restrictors of variable reduced cross-sectional areas were introduced to the outflow of the inflation syringes to investigate the effect of flow resistance on anchoring balloon inflation profiles. Variations in maximum inflation pressures (range: 75-355 kPa) were observed among the different users. There were no significant differences in maximum inflation pressure between brands at any of the 3 simulated hand forces (P = .97). Increasing the flow resistance significantly reduces the applicable inflation pressure of all hand forces (P < .001). Specifically, the difference in inflation pressure between heavy- and light-handed forces is reduced from over 405 kPa to under 65 kPa. Introducing flow resistance does not result in a significant difference in inflation pressure between brands (P = .254). There is significant user variability in urinary catheter balloon inflation pressure. This variation can be significantly reduced by introducing flow resistance to the inflation technique.

Abstract: There is increasing evidence to implement multiparametric magnetic resonance imaging (mpMRI) for biopsy-naive men with clinically suspected prostate cancer (PCa). This will reduce the number of unnecessary trans rectal ultrasound biopsies (TRUS-Bx) performed and reduce the number of indolent cancers diagnosed. To assess current clinical practices for investigating clinically suspected prostate cancer in Ireland and determine if private health insurance providers are offering mpMRI scans in biopsy-naive men. Each health insurance provider procedure code was reviewed. The indications and requirements for prostate mpMRI in the setting of diagnosis, staging, surveillance, and recurrence were assessed for each health care provider. Current practices adopted by accredited referral clinics for suspected prostate cancer were reviewed. Two of the three leading health insurance providers, which between them cover 46% of the private health insurance market in Ireland, provide pre-biopsy mpMRI cover as of April 2019. This leaves almost half of those insured with no accessibility to pre-biopsy mpMRI. This is in contrast to the majority of public NCCP hospitals that offer pre-biopsy mpMRI for clinically suspected prostate cancer. Pre-biopsy mpMRI for clinically suspected prostate cancer is emerging as a standard of practice in Ireland. International guidelines are also changing to reflect latest clinical trial evidence. Private health insurance providers should amend their policies to reflect current clinical practices already adopted in the public sector.

Abstract: The exact biological mechanism governing the radioresistant phenotype of prostate tumours at a high risk of recurrence despite the delivery of advanced radiotherapy protocols remains unclear. This study analysed the protein expression profiles of a previously generated isogenic 22Rv1 prostate cancer model of radioresistance using DigiWest multiplex protein profiling for a selection of 90 signalling proteins. Comparative analysis of the profiles identified a substantial change in the expression of 43 proteins. Differential PARP-1, AR, p53, Notch-3 and YB-1 protein levels were independently validated using Western Blotting. Pharmacological targeting of these proteins was associated with a mild but significant radiosensitisation effect at 4Gy. This study supports the clinical relevance of isogenic in vitro models of radioresistance and clarifies the molecular radiation response of prostate cancer cells.

Abstract: Social media is the interaction among people in which they create, share or exchange information and ideas in virtual communities and web-based networks. This year, the Irish Society of Urology (ISU) expanded its involvement in social media with a preregistered Twitter hashtag (#ISU14) for the annual meeting. The aim of this study was to highlight the use of Twitter at an annual national meeting held in 2014. The Symplur healthcare analytics website was used to prospectively examine traffic related to the 2014 ISU Annual Meeting. This feature was used to generate statistics for the number of impressions, unique tweets (excluding retweets) and distinct contributors who used the indexing hashtag #ISU14. In idual tweets were assessed using the conference hashtag on the Twitter website. The total number of attendees at the conference was 119, and 99 in iduals participated in Twitter using the conference hashtag (#ISU14). 31 % of attendees participated in tweeting at the conference. Over the course of the conference, a total of 798 unique tweets were generated, creating over 665,000 impressions in cyberspace. 590 (73.9 %) tweets were generated from attendees at the conference, while 26.1 % of tweets were from virtual followers. 702 (87.9 %) tweets were from urologists and 439 (55 %) tweets were of scientific nature. Tweet activity peaked during the guest lectures on both days. Twitter use at the ISU has been shown to facilitate interaction between delegates and allows users to follow as well as participate from afar.

Abstract: Knowledge of local antimicrobial resistance patterns is essential for evidence-based empirical antibiotic prescribing, and a cutoff point of 20% has been suggested as the level of resistance at which an agent should no longer be used empirically. We sought to identify the changing incidence of causative uropathogens over an 11-year period. We also examined the trends in antibiotic resistance encountered in both the pooled urine s les and those where the causative organism was Escherichia coli. A retrospective analysis of the antimicrobial resistance within the positive community urine isolates over the 11-year period, 1999 to 2009, in a single Dublin teaching hospital was performed. In total 38,530 positive urine s les processed at our laboratory originated in the community of which 23,838 (56.7%) had E. coli as the infecting organism. The prevalence of E. coli has been increasing in recent years in community UTIs with 70.4% of UTIs in the community caused by E.coli in 2009. Ampicillin and trimethoprim were the least-active agents against E. coli with mean 11-year resistance rates of 60.8 and 31.5%, respectively. Significant trends of increasing resistance over the 11-year period were identified for trimethoprim, co-amoxyclav, cefuroxime and gentamicin. Ciprofloxacin remains a reasonable empirical antibiotic choice in this community with an 11-year resistance rate of 10.6%. Higher antibiotic resistance rates were identified in the male population and in children. Resistance rates to commonly prescribed antibiotics are increasing significantly. This data will enable evidence-based empirical prescribing which will ensure more effective treatment and lessen the emergence of resistant uropathogens in the community.

Abstract: Social media (SoMe) comprises a number of internet-based applications that have the capability to disseminate multimodal media and allow for unprecedented inter-user connectivity. The role of Twitter has been studied in conferences and education moreover, there is increasing evidence that patients are more likely to use social media for their own health education. The aim of this study was to assess the impact of social media platforms on the impact factor of both urological and paediatric journals that publish on paediatric urology, and to assess parental awareness of social media in paediatric urology. A filtered Journal of Citation Reports (JCR) search was performed for the period 2012-16 for journals that published articles on paediatric urology. Journals were ranked according to impact factor, and each in idual journal website was accessed to assess for the presence of social media. Parents in paediatric urology clinics and non-paediatric urology patients also filled out a questionnaire to assess for awareness and attitudes to social media. All statistical analysis was performed using Prism 6 software (Prism 6, GraphPad Software, California, USA). Overall, there were 50 urological journals and 39 paediatric journals with a mean impact factor of 2.303 and 1.766, respectively. There was an overall average increase in impact factor across all urological journals between 2012 and 16. The presence of a Twitter feed was statistically significant for a rise in impact factor over the 4 years (P = 0.017). The cohort of parents was statistically more likely to have completed post-secondary education, to have and access to a social media profile, use it for health education, and use it to access journal hysician/hospital social media accounts. This study examined, for the first time, the role of social media in paediatric urology, and demonstrated that SoMe use is associated with a positive influence in impact factor, but also a parental appetite for it. Limitations included a non-externally validated questionnaire. There may also have been bias in larger journals that generate and maintain social media platforms such as Twitter, which may then in turn have an influence on impact factor. Social media use within paediatric urology was associated with a higher impact factor, which remained significant after 4 years of analysis. Parents were more likely to use a wide variety of social media to search for conditions and physicians/healthcare providers therefore, journals and institutions need to embrace and endorse SoMe as a potential source of important clinical information.

Abstract: To determine the probability of visible hematuria with antithrombotic agents and to evaluate association of urologic etiology in antithrombotic-related hematuria. Preferred Reporting Items in Systematic Reviews and Meta-Analyses guidelines were followed to conduct a systematic review using search engines PUBMED and SCOPUS with the terms "(hematuria) OR (haematuria) OR urinary bleeding)) AND ((anticoagulants) OR anticoagulation) OR noac) OR novel anticoagulants) OR antiplatelet) OR dabigatran) OR rivaroxaban) OR apixaban) OR warfarin) OR aspirin) OR heparin) OR dipyridamole)." Raw data were used to perform a pooled analysis. Chi-square and logistic regression analysis were used for statistical analyses. Twenty-two studies describing 175,114 patients met inclusion criteria. Odds ratio of hematuria with warfarin to rivoraxaban was 33 and warfarin to dabigatran was 16. The odds ratio of hematuria for oral anticoagulant (26.7%) to prophylactic parenteral anticoagulant (1.1%) agents was 9.6. Antiplatelet agents are 76 times less likely to cause hematuria compared to anticoagulants. Odds of hematuria with aspirin were 6.7 times the odds with clopidogrel and 3.5 times the odds with ticagrelor. Dabigatran was 198 times more likely to cause major hematuria compared to warfarin, whereas clopidogrel is 1.2 times more likely to cause major hematuria compared to aspirin. Urologic pathology was identified in 44% (234/532) of cases, malignancy in 24%. Warfarin use poses the greatest risk for hematuria but is unlikely to cause major hematuria, whereas novel antithrombotic agents are more commonly associated with major hematuria. This review further characterizes the risk profile of antithrombotic agents and associated hematuria to equip clinicians with knowledge to choose an appropriate antithrombotic agent in patients with high-risk hematuria.

Abstract: Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user’s needs and established successful practice. In 2013, the Fusarium community voiced near unanimous support for a concept of Fusarium that represented a clade comprising all agriculturally and clinically important Fusarium species, including the F. solani species complex (FSSC). Subsequently, this concept was challenged in 2015 by one research group who proposed iding the genus Fusarium into seven genera, including the FSSC described as members of the genus Neocosmospora, with subsequent justification in 2018 based on claims that the 2013 concept of Fusarium is polyphyletic. Here, we test this claim and provide a phylogeny based on exonic nucleotide sequences of 19 orthologous protein-coding genes that strongly support the monophyly of Fusarium including the FSSC. We reassert the practical and scientific argument in support of a genus Fusarium that includes the FSSC and several other basal lineages, consistent with the longstanding use of this name among plant pathologists, medical mycologists, quarantine officials, regulatory agencies, students, and researchers with a stake in its taxonomy. In recognition of this monophyly, 40 species described as genus Neocosmospora were recombined in genus Fusarium, and nine others were renamed Fusarium. Here the global Fusarium community voices strong support for the inclusion of the FSSC in Fusarium, as it remains the best scientific, nomenclatural, and practical taxonomic option available.

Abstract: Circulating tumour cells (CTCs) represent a morphologically distinct subset of cancer cells, which aid the metastatic spread. The ExPeCT trial aimed to examine the effectiveness of a structured exercise programme in modulating levels of CTCs and platelet cloaking in patients with metastatic prostate cancer. Participants (n = 61) were randomised into either standard care (control) or exercise arms. Whole blood was collected for all participants at baseline (T0), three months (T3) and six months (T6), and analysed for the presence of CTCs, CTC clusters and platelet cloaking. CTC data was correlated with clinico-pathological information. Changes in CTC number were observed within group over time, however no significant difference in CTC number was observed between groups over time. Platelet cloaking was identified in 29.5% of participants. A positive correlation between CTC number and white cell count (WCC) was observed (p = 0.0001), in addition to a positive relationship between CTC clusters and PSA levels (p = 0.0393). The presence of platelet cloaking has been observed in this patient population for the first time, in addition to a significant correlation between CTC number and WCC.

Abstract: A man in his 70s was referred to plastic surgery with a suspected foreign body in the pulp of his right index finger. An excisional biopsy was performed for a presumed foreign body granuloma. Histology revealed metastatic renal cell carcinoma (mRCC). CT imaging demonstrated a 7.4 cm heterogeneous mass arising from the upper pole of the left kidney consistent with primary renal malignancy, in addition to a 9 mm lung nodule. He underwent an uncomplicated left laparoscopic cytoreductive nephrectomy and made a satisfactory recovery. To our knowledge, this is the first reported case of primary mRCC presenting with digital soft tissue metastasis. Cytoreductive nephrectomy with metastasectomy is the preferred management for mRCC where feasible. For unfavourable mRCC cases, first-line systemic therapy is indicated. Adjuvant systemic therapy in mRCC is currently limited to clinical trials, though promising data emerging on the use of pembrolizumab may herald a future shift in practice.

Abstract: To assess the emerging use of Twitter by urological journals. A search of the Journal of Citation Reports 2012 was performed to identify urological journals. These journals were then searched on Twitter.com. Each journal website was accessed for links to social media (SoMe). The number of 'tweets', followers and age of profile was determined. To evaluate the content, over a 6-month period (November 2013 to April 2014), all tweets were scrutinised on the journals Twitter profiles. To assess SoMe influence, the Klout score of each journal was also calculated. In all, 33 urological journals were identified. Eight (24.2%) had Twitter profiles. The mean (range) number of tweets and followers was 557 (19-1809) and 1845 (82-3692), respectively. The mean (range) age of the twitter profiles was 952 (314-1758) days with an average 0.88 tweets/day. A Twitter profile was associated with a higher mean impact factor of the journal (mean [sd] 3.588 [3.05] vs 1.78 [0.99], P = 0.013). Over a 6-month period, November 2013 to April 2014, the median (range) number of tweets per profile was 82 (2-415) and the median (range) number of articles linked to tweets was 73 (0-336). Of these 710 articles, 152 were Level 1 evidence-based articles, 101 Level 2, 278 Level 3 and 179 Level 4. The median (range) Klout score was 47 (19-58). The Klout scores of major journals did not exactly mirror their impact factors. SoMe is increasingly becoming an adjunct to traditional teaching methods, due to its convenient and user-friendly platform. Recently, many of the leading urological journals have used Twitter to highlight significant articles of interest to readers.

Abstract: To assess major areas of technological innovation in urology in the last 20 years using patent and publication data. Patent and MEDLINE databases were searched between 1980 and 2012 electronically using the terms urology OR urological OR urologist AND "surgeon" OR "surgical" OR "surgery". The patent codes obtained were grouped in technology clusters, further analyzed with in idual searches, and growth curves were plotted. Growth rates and patterns were analyzed, and patents were correlated with publications as a measure of scientific support and of clinical adoption. The initial search revealed 417 patents and 20,314 publications. The top 5 technology clusters in descending order were surgical instruments including urinary catheters, minimally invasive surgery (MIS), lasers, robotic surgery, and image guidance. MIS and robotic surgery were the most emergent clusters in the last 5 years. Publication and patent growth rates were closely correlated (Pearson coefficient 0.78, P <.01), but publication growth rate remained constantly higher than patent growth, suggesting validated scientific support for urologic innovation and adoption into clinical practice. Patent metrics identify emergent technological innovations and such trends are valuable to understand progress in the field of urology. New surgical technologies like robotic surgery and MIS showed exponential growth in the last decade with good scientific vigilance.

Abstract: To determine the incidence of 'burnout' among UK and Irish urological consultants and non-consultant hospital doctors (NCHDs). The second objective was to identify possible causative factors and to investigate the impact of various vocational stressors that urologists face in their day-to-day work and to establish whether these correlate with burnout. The third objective was to develop a new questionnaire to complement the Maslach Burnout Inventory (MBI), more specific to urologists as distinct from other surgical/medical specialties, and to use this in addition to the MBI to determine if there is a requirement to develop effective preventative measures for stress in the work place, and develop targeted remedial measures when in iduals are affected by burnout. A joint collaboration was carried out between the Irish Society of Urology (ISU) and the British Association of Urological Surgeons (BAUS). Anonymous voluntary questionnaires were sent to all current registered members of both governing bodies. The questionnaire comprised two parts: the first part encompassed sociodemographic data collection and identifying potential risk factors for burnout, and the second used the MBI to objectively assess for workplace burnout. To evaluate differences in burnout, 2 × 2 contingency tables and Fischer's exact probability tests were used. In all, 575 urologists responded to the online survey out of a total of 1380 invites, yielding a 42% response rate. All respondents were aged <75 years (median age 45 years), with men representing 87.5% of respondents. In all, 75% of respondents worked in England, followed by the Republic of Ireland (9%), Scotland (8%), Northern Ireland (4%), and Wales (3%). In all, 79% of respondents were consultants, with 13% representing training posts, and 40% of respondents held a professorship/clinical lead position. Respondents' countries of origin included England, Scotland, Ireland, India, Wales, Malaysia, Pakistan and Sri Lanka. Overall, the mean emotion exhaustion (EE) score was 23.5, representing a moderate level of EE. The mean depersonalisation (DP) score was 8.2, representing a moderate level of DP. The mean personal achievement (PA) score was 17.1, representing high levels of PA. In all, 86 respondents (15%) reported self-medication with non-prescription drugs or alcohol to combat signs and symptoms of burnout, while 46 (8%) sought professional help for symptoms of burnout. In all, 460 respondents (80%) felt that burnout should be evaluated amongst members of the ISU/BAUS, and 345 (60%) would avail of counselling if provided. This is the first study to address the issue of burnout across two separate health systems in the UK and Ireland. This study has shown previously undescribed high levels of burnout characterised by EE and DP, with associated significant levels of self-medication amongst a male-predominant cohort. Burnout was attributed to non-surgical administrative/institutional factors, with most respondents reporting support for staff evaluation and the provision of counselling services. This pilot study lends itself to the creation of risk stratification for urologists, and an opportunity to provide educational resources, training/development programmes, and collegial and administrative support pathways.
