Introduction: Laparoscopic nephrectomy has gained widespread acceptance as a treatment for both benign and malignant conditions and is becoming increasingly popular in Irish hospitals. We report a single surgeon, single centre experience with 20 consecutive laparoscopic nephrectomies comparing them to 20 open cases performed prior to the establishment of a laparoscopic service.Methodology: A retrospective comparative analysis was carried out over an 18 month period. Transperitoneal approach was used in the laparoscopic group with renal vessels divided using an Endo GIA stapling device. Parameters examined included age, weight, indication, operative time, blood loss, tumour size, length of stay and analgesic requirements. Comparison was made with 20 open nephrectomies.Results: Mean age (p=0.26) and weight (p=0.08) were similar in both groups. Average tumour size was similar (4.98 cm [range 2.8-9] in laparoscopic group versus 6.4 cm [range 3-10], p=0.61). Mean operative blood loss was reduced in the laparoscopic group (65 ml (range 50-200) versus 351 ml (50-1740) (p=or<0.05 L.N. versus O.N.). Laparoscopic patients were discharged earlier; 3.9 days (range 3-6) versus 6.5 (range 5-11) postoperatively (p=or<0.05 L.N. versus O.N.). Analgesia requirements were reduced in terms of both total hours using PCA (25.05 hours [range 1-45] versus 41.6 hours (range 7-226)) (p=or<0.05 L.N. versus O.N.) and total morphine requirements (35.5 mg [range 2-94] versus 72.4 mg [range 18-113] [p=or<0.05 L.N. versus O.N.]). There were no complications in the laparoscopic group, while one patient developed an incisional hernia in the open group.Conclusion: Laparoscopic nephrectomy is less invasive and demonstrates improved results in terms of analgesia, blood loss and reduced overall stay.

Objectives: To assess human in vivo intrarenal pressure (IRP) and peristaltic activity at baseline and after ureteric stent placement, using a narrow calibre pressure guidewire placed retrogradely in the renal pelvis., Patients and Methods: A prospective, multi-institutional study recruiting consenting patients undergoing ureteroscopy was designed with ethical approval. Prior to ureteroscopy, the urinary bladder was emptied and the COMET™ II pressure guidewire (Boston Scientific) was advanced retrogradely via the ureteric orifice to the renal pelvis. Baseline IRPs were recorded for 1-2 min. At procedure completion, following ureteric stent insertion, IRPs were recorded for another 1-2 min. Statistical analysis of mean baseline IRP, peristaltic waveforms and frequency of peristaltic contractions was performed, thereby analysing the influence of patient variables and ureteric stenting., Results: A total of 100 patients were included. Baseline mean (±SD) IRP was 16.76 (6.4) mmHg in the renal pelvis, with maximum peristaltic IRP peaks reaching a mean (SD) of 25.75 (17.9) mmHg. Peristaltic activity generally occurred in a rhythmic, coordinated fashion, with a mean (SD) interval of 5.63 (3.08) s between peaks. On univariate analysis, higher baseline IRP was observed with male sex, preoperative hydronephrosis, and preoperative ureteric stenting. On linear regression, male sex was no longer statistically significant, whilst the latter two variables remained significant (P = 0.004; P < 0.001). The mean (SD) baseline IRP in the non-hydronephrotic, unstented cohort was 14.19 (4.39) mmHg. Age, α-blockers and calcium channel blockers did not significantly influence IRP, and no measured variables influenced peristaltic activity. Immediately after ureteric stent insertion, IRP decreased (mean [SD] 15.18 [5.28] vs 16.76 [6.4] mmHg, P = 0.004), whilst peristaltic activity was maintained., Conclusions: Human in vivo mean (SD) baseline IRP is 14.19 (4.39) mmHg in normal kidneys and increases with both hydronephrosis and preoperative ureteric stenting. Mean (SD) peristaltic peak IRP values of 25.75 (17.9) mmHg are reached in the renal pelvis every 3-7 s and maintained in the early post-stent period., (© 2024 BJU International.)

Objectives: To evaluate the pressure range generated in the human renal collecting system during ureteroscopy (URS), in a large patient sample, and to investigate a relationship between intrarenal pressure (IRP) and outcome., Patients and Methods: A prospective multi-institutional study was conducted, with ethics board approval; February 2022-March 2023. Recruitment was of 120 consecutive consenting adult patients undergoing semi-rigid URS and/or flexible ureterorenoscopy (FURS) for urolithiasis or diagnostic purposes. Retrograde, fluoroscopy-guided insertion of a 0.036-cm (0.014″) pressure guidewire (COMET™ II, Boston Scientific, Marlborough, MA, USA) to the renal pelvis was performed. Baseline and continuous ureteroscopic IRP was recorded, alongside relevant operative variables. A 30-day follow-up was completed. Descriptive statistics were applied to IRP traces, with mean (sd) and maximum values and variance reported. Relationships between IRP and technical variables, and IRP and clinical outcome were interrogated using the chi-square test and independent samples t-test., Results: A total of 430 pressure traces were analysed from 120 patient episodes. The mean (sd) baseline IRP was 16.45 (5.99) mmHg and the intraoperative IRP varied by technique. The mean (sd) IRP during semi-rigid URS with gravity irrigation was 34.93 (11.66) mmHg. FURS resulted in variable IRP values: from a mean (sd) of 26.78 (5.84) mmHg (gravity irrigation; 12/14-F ureteric access sheath [UAS]) to 87.27 (66.85) mmHg (200 mmHg pressurised-bag irrigation; 11/13-F UAS). The highest single pressure peak was 334.2 mmHg, during retrograde pyelography. Six patients (5%) developed postoperative urosepsis; these patients had significantly higher IRPs during FURS (mean [sd] 81.7 [49.52] mmHg) than controls (38.53 [22.6] mmHg; P < 0.001)., Conclusions: A dynamic IRP profile is observed during human in vivo URS, with IRP frequently exceeding expected thresholds. A relationship appears to exist between elevated IRP and postoperative urosepsis., (© 2023 The Authors. BJU International published by John Wiley & Sons Ltd on behalf of BJU International.)

Background: Informed consent is an integral part of the process prior to any surgical procedure [1]. Flexible cystoscopy is a common day case urological procedure and it is the gold standard investigation for visible haematuria [2]., Aim: To assess if postal consent is a suitable form of gaining informed consent for flexible cystoscopy., Methods: Patients booked for a flexible cystoscopy are initially reviewed in clinic. An information leaflet with an attached consent form is then posted to their home 2 weeks prior to their procedure. We designed a short questionnaire, to assess patient's satisfaction and understanding of the literature, given to them after the procedure., Results: Sixty-seven questionnaires were completed. The mean age was 54. Sixty patients (93%) think that postal consent is of benefit to the patient. Sixty-one patients (91%) read the information sheet and felt that there was enough information regarding the procedure on it. Fifty-four patients (81%) had no difficulty understanding the consent form. Forty patients (60%) signed the form prior to arrival in the hospital., Conclusion: Postal consent is commonly used for gastro-intestinal endoscopy procedures. Postal consent for flexible cystoscopy is not well reported in the literature. Our study shows postal consent to be a suitable form of gaining informed consent for flexible cystoscopy., (© 2021.

Objective: Rezum technology uses heat from radiofrequency-generated water vapour to ablate prostate tissue. We evaluate the introduction of this thermal therapy to an Irish teaching hospital for the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia., Methods: A pilot study of men with moderate to severe lower urinary tract symptoms who underwent Rezum treatment to the prostate was performed. Perioperative efficacy was evaluated using international prostate symptom score (IPSS), quality of life score (IPSS-QOL), uroflowmetry and post-void residual (PVR) volumes. Costs were evaluated and compared against matched patients undergoing the standard of care, transurethral resection of the prostate (TURP)., Result: Ten patients with a mean age of 70 ± 9 years who met the inclusion criteria underwent Rezum treatment. Mean PSA was 4.73 ± 4 ng/mL and mean prostate volume 72 ± 30 cc. Rezum therapy significantly improved both IPSS by 74% from mean baseline score of 20.8 ± 4 to 5.3 ± 1.49 (p < 0.001) and IPSS-QOL score by 84% from mean baseline score of 4.4 ± 0.7 to 0.6 ± 0.7 (p < 0.001) at 3 months. Maximum flow rate increase by 44% from 9.26 ± 2.5 to 13.34 ± 2.3 mL/s (p < 0.001). When compared to ten matched patients undergoing TURP in the same period, there was a significant cost saving of €1986.52 per patient for Rezum, overall up-front cost saving of €22,819 with an additional 19 bed days and 5 theatre hours spared., Conclusion: Rezum, a minimally invasive thermal therapy, provides significantly improved symptom relief and quality of life with a significant cost saving to the institution., (© 2021.

Introduction and Hypothesis: The aim of this study is to evaluate the trends in stress urinary incontinence (SUI) surgery since the 2018 pause on use of the polypropylene (PP) mid-urethral sling (MUS) and to quantify the effect this has had on surgical training., Methods: Two anonymous surveys were sent to all current urology trainees and to all consultant surgeons who specialise in stress urinary incontinence surgery., Results: Prior to the pause, 86% (6 out of 7) of consultant urologists and 73% (11 out of 15) of consultant gynaecologists would "always"/"often" perform MUS for SUI. After that, 100% (22 out of 22) of consultants reported that they "never" perform MUS. There has been a modest increase in the use of urethral bulking agent (UBA) procedures among urologists, with 43% (3 out of 7) now "often" performing this, compared with 71% (5 out of 7) "never" performing it pre-2018. Trainee exposure to SUI surgery reduced by 75% between 2016 and 2020. Despite a ten-fold increase in UBA procedures logged by trainees, the decline in MUS has resulted in a major reduction in total SUI surgeries. Coinciding with this decrease in surgeries, there was a 56% reduction in trainees' self-assessed competence at SUI surgery. Thirteen percent of trainees are interested in specialising in Female Urology and those trainees had significantly greater exposure to SUI procedures during their training than those who did not (p = 0.0072)., Conclusions: This study has identified a downward trend in SUI surgery, which is concerning for the undertreatment of females with SUI. A decline in SUI surgery training has resulted in reduced trainee confidence and interest in this subspecialty., (© 2021. The Author(s).)

Background: The aim of this study is to systematically compare rates of erosion and chronic pain after mesh insertion for pelvic organ prolapse (POP) and stress urinary incontinence (SUI) surgery., Methods: A systematic electronic search was performed on studies that evaluated the incidence of erosion and chronic pain after mesh insertion for POP or SUI. The primary outcome measurement was to compare mesh erosion rates for POP and SUI surgery. Secondary outcome measurements were incidence of de novo pain and a comparison of patient demographics for both surgeries., Results: Twenty-six studies on 292,606 patients (n = 9077 for POP surgery and n = 283,529 for SUI surgery) met the inclusion criteria. Median follow-up was 26.38 ± 22.17 months for POP surgery and 39.33 ± 27.68 months for SUI surgery. Overall, the POP group were older (p < 0.0001) and had a lower BMI (p < 0.0001). Mesh erosion rates were significantly greater in the POP group compared to the SUI group (4% versus 1.9%) (OR 2.13; 95% CI 1.91-2.37; p < 0.0001). The duration from surgery to onset of mesh erosion was 306.84 ± 183.98 days. There was no difference in erosion rates between abdominal and transvaginal mesh for POP. There was no difference in erosion rates between the transobturator and retropubic approach for SUI. The incidence of chronic pain was significantly greater in the POP group compared to the SUI group (6.7% versus 0.6%) (OR 11.02; 95% CI 8.15-14.9; p < 0.0001). The duration from surgery to onset of chronic pain was 325.88 ± 226.31 days., Conclusions: The risk of mesh erosion and chronic pain is significantly higher after surgery for POP compared to SUI. These significant complications occur within the first year after surgery.

Background: We sought to determine the rate of emergency department (ED) attendance for complications after ureterorenoscopy (URS) for stone disease and to identify risk factors for ED attendance after URS., Methods: An analysis of all patients undergoing URS over 12 months at a single institution was performed. Patient demographics, preoperative and intraoperative variables associated with postoperative complications and subsequent ED attendance were collected. Logistic regression analyses were performed to determine predictors of URS complications presenting to ED., Results: In total, 202 ureteroscopies were performed on 142 patients for urolithiasis. The mean age was 50.73 ± 13.93 and 66% were male. The incidence of re-presentation to ED was 14.8% (n = 30). Patients presented with postoperative pain (n = 10; 4.95%), pyrexia (n = 9; 4.46%), urinary tract infection (UTI) (n = 7, 3.47%), haematuria (n = 3, 1.49%) and urosepsis (n = 1; 0.5%). Significant risk factors for ED attendance included preoperative stent dwell time > 30 days (P = 0.004), recently treated positive preoperative urine culture (P < 0.0001), stone size ≥ 13 mm (P = 0.043), stone location mid-ureter (P = 0.036) and female gender (P = 0.005). The following factors did not predict ED attendance, stent omission, access sheath utilization and operation duration., Conclusion: Risk factors for ED attendance after URS include prolonged pre-stent dwell time, stone size ≥ 13 mm, treatment for a positive preoperative urine culture, mid-ureteric stone location and female gender. Urologists should be aware of these findings to decrease the risk of emergency re-presentation after elective URS surgery.

Background: The prevalence of intraductal carcinoma of the prostate (IDC-P) is poorly studied in the Irish population. This study investigated the incidence and clinicopathologic characteristics of IDC-P in an Irish prostate cancer (PCa) patient cohort. The study also discusses the rationale for genetic counseling and screening in Irish patients with familial risk factors for IDC-P., Materials and Methods: This study investigated patients diagnosed with IDC-P on prostate biopsy from 2012 to 2016. Primary outcome measurements were incidence, management, and clinical outcomes after follow-up in patients with IDC-P. The secondary outcome measurement was to identify a familial link for IDC-P., Results: A total of 1,143 patients were diagnosed with PCa on needle biopsy, of which 30 (2.3%) had concomitant IDC-P. Mean age and prostate-specific antigen at diagnosis were 68.6 ± 10.5 years (range 53-85 years) and 9.15 ± 8.65 ng/mL (range 2.1-166 ng/mL), respectively. In total, 17 of 30 patients (57%) were diagnosed with concomitant high-grade (i.e., ≥Gleason score 8) PCa. Eight patients (27%) were treated with radical prostatectomy; of which five had biochemical recurrence (BCR) after 10.55 ± 25.9 months. Eleven patients (37%) received radical radiotherapy; of which one had BCR after 36 months. Eleven patients (37%) presented with advanced PCa and were managed with androgen deprivation therapy ± chemotherapy. A family history for PCa in first-degree relatives was found in eight patients (27%)., Conclusions: IDC-P is associated with more aggressive clinicopathologic features and an increased risk of BCR after treatment. In Ireland, clinical guidelines and a genetic screening pathway are required to provide early detection and appropriate multimodal management of patients with IDC-P., Competing Interests: All authors have no conflict of interest to declare., (© 2020 Asian Pacific Prostate Society, Publishing services by Elsevier.)

Background: Acute urinary retention (AUR) is a common urologic emergency. However, its management is not standardized due to lack of clinical guidelines., Aims: We retrospectively reviewed the treatment of all male patients admitted to our institution with AUR over 12 months., Methods: Data was obtained from the HIPE (Hospital Inpatient Enquiry) data system, each patient's electronic discharge summary and from patient medical records., Results: There were 130 AUR admissions during the period. About 74 admissions were due to benign prostatic enlargement (BPE). Of these, 45.9% (n = 34) passed their trial without catheter (TWOC). The remainder (n = 40) failed their TWOC necessitating recatheterization and consideration for transurethral resection of prostate (TURP) or re-TWOC. An indwelling urinary catheter (IDC) was inserted for 27.5% (n = 11) of patients with a failed TWOC secondary to comorbidities. This group had a mean age of 78 years (range 68-96 years). Of those who failed their TWOC, 32.5% (n = 13) had a TURP on index admission. Of the remaining 16 patients with failed TWOC, 75% (n = 12) were discharged with an IDC and readmitted for an elective TURP with a median waiting time of 55 days (range 17-138 days). 18.75% (n = 3) passed a re-TWOC and thus offset the need to have any surgical intervention and 6.25% (n = 1) proceeded to a radical retropubic prostatectomy for biopsy proven prostate adenocarcinoma., Conclusion: Admission of patients with acute urinary retention leads to a definitive management decision and reduced prolonged catheterization.

Introduction: Ureteric stents are frequently placed following endo-urological procedures. These stents cause significant morbidity for patients. Standard ureteric stents are removed by flexible cystoscopy. This procedure can be unpleasant for patients and requires additional resources. A newly designed magnetic stent allows removal in an outpatient setting. The aim of our study is to compare the magnetic stent and standard ureteric stents with regard to morbidity, pain on stent removal and cost-effectiveness., Methods: This study was carried out across two sites between September 2016 and July 2017. In site A, a magnetic stent (Urotech, Black-Star®) is removed by magnetic retrieval device. Fifty consecutive patients completed the validated Ureteric Stent Symptom Questionnaire (USSQ) and visual analogue scale (VAS) at the time of stent removal. On site B, a soft polyurethane stent (Cook Universa) was removed by flexible cystoscopy. Fifty patients were identified retrospectively and completed questionnaires by post. Cost analysis was also performed., Results: One hundred questionnaires were included for analysis. No significant difference in stent morbidity as assessed by the USSQ was shown between both groups. Median duration of stenting was significantly shorter in the magnetic stent group (5.5 versus 21.5 days, p < 0.001). Mean pain on stent removal was significantly less with magnetic retrieval (2.9 versus 3.9, p < 0.05). Complication rates were similar in both groups. Cost analysis showed a cost saving of €203 per patient with the magnetic stent group., Conclusion: Magnetic stents cause similar morbidity for patients compared with standard stents removed by flexible cystoscopy; they are associated with less pain at removal and are cost saving.

Objectives: Systemic lupus erythematosus and granulomatosis with polyangiitis are systemic inflammatory conditions associated with renalfailure that can recur after renal transplant. Patients with these conditions are treated with chronic immunosuppression, potentially increasing risk of secondary malignancies. Here, we investigated long-term outcomes in renal transplant recipients with these conditions., Materials and Methods: Transplant recipients with end-stage kidney disease due to systemic lupus erythematosus and granulomatosis with polyangiitis seen between 1982 and 2016 at a national kidney transplant center were included. Primary outcome variables were long-term allograft survival and incidence of secondary malignancy. Secondary outcome measures were incidence of delayed graft function, primary disease recurrence, and serum creatinine at follow-up., Results: Ninety-eight transplant procedures (90 from deceased donors) in 92 consecutive patients (mean age 42.3 ± 14.4 y) were included: 55 with systemic lupus erythematosus and 37 with granulomatosis with polyangiitis. Follow-up duration was 110.53 ± 81.95 months (range, 1-393 mo). Overall renal allograft survival was 94.7% at 1 year, 85.4% at 5 years, and 75.4% at 10 years posttransplant. Patientswith systemic lupus erythematosus showed overall allograft survival of 91.6% at 1 year, 84.3% at 5 years, and 74.4% at 10 years. There was 1 allograft failure due to recurrence of primary disease in this group. Patients with granulomatosis with polyangiitis showed overall allograft survival of 100% at 1 year, 92.4% at 5 years, and 92.4% at 10 years. There were 21 mortalities, with 5 (23.8%) due to secondary malignancy. In total, 46 malignancies were diagnosed in 31 patients., Conclusions: We found excellent long-term renal allograft survival rates in patients with systemic lupus erythematosus and granulomatosis with polyangiitis, with secondary malignancy rates similar to those shown in recipients without autoimmune diseases. These findings provide clinicians with long-term data on transplant recipients with end-stage renal failure due to systemic inflammatory conditions.

Objectives: We reviewed the incidence, management, and survival outcomes of prostate cancer among kidney transplant recipients and compared these characteristics with a national population (nonrecipients)., Materials and Methods: A retrospective study was performed on all kidney transplant recipients from a National Kidney Transplant Centre who were subsequently diagnosed with prostate cancer. Primary outcome variables included comparisons of incidence and 5-year overall survival in kidney transplant recipients versus nonrecipients after treatment of prostate cancer. Secondary outcome variables were prostate-specific antigen levels at diagnosis, Gleason grade, treatment strategy, and morbidity from treatment among kidney transplant recipients., Results: Of 4048 kidney transplants performed, 3020 were male recipients (63.9%). In total, 34 kidney transplant recipients (1.1%) were diagnosed with prostate cancer 109 ± 83 months (range, 7-372 mo) after transplant. The mean age at prostate cancer diagnosis was 64 ± 7 years, median prostate-specific antigen level was 10 ng/dL (range, 2.6-771 ng/dL), and 76% (n = 26/34) were diagnosed with localized disease. The incidence of prostate cancer was 1126/100 000 in kidney transplant recipients compared with 160/100 000 nonrecipients in Ireland (P = .01). Treatment strategies included curative radiotherapy (n = 18), curative surgery (n = 2), androgen deprivation therapy (n = 8), and watchful waiting (n = 6). Overall survival rates at 1, 3, and 5 years were not significantly different between kidney transplant recipients with prostate cancer versus nonrecipients with prostate cancer (98% vs 98%, 80% vs 79%, and 77% vs 72%, respectively, P = .8)., Conclusions: The incidence of prostate cancer is significantly higher among kidney transplant recipients compared with nonrecipients in the general population, with most diagnosed with localized disease. Definitive management guidelines should be developed to increase awareness and optimize treatment options in this unique patient cohort.

Simulation in surgery is a safe and cost-effective way of training. Operating room performance is improved after simulation training. The necessary attributes of surgical simulators are acceptability and cost-effectiveness. It is also necessary for a simulator to demonstrate face, content, predictive, construct and concurrent validity. Urologists have embraced robot-assisted surgery. These procedures require steep learning curves. There are 6 VR simulators available for robot-assisted surgery; the daVinci Skills Simulator (dVSS), the Mimic dV Trainer (MdVT), the ProMIS simulator, the Simsurgery Educational Platform (SEP) simulator, the Robotic Surgical Simulator (RoSS) and the RobotiX Mentor (RM). Their efficacy is limited by the lack of comparative studies, standardisation of validation and high cost. There are a number of robotic surgery training curricula developed in recent years which successfully include simulation training. There are growing calls for these simulators to be incorporated into the urology training curriculum globally to shorten the learning curve without compromising patient safety. Surgical educators in urology should aim to develop a cost-effective, acceptable, validated simulator that can be incorporated into a standardised, validated robot-assisted surgery training curriculum for the next generation of robotic surgeons.

Introduction: Transplant units are exploring strategies to increase the availability of donor kidneys. The use of en-bloc kidney transplantation (EBKT) from paediatric donors represents one potential solution. We present our long-term experience with paediatric EBKT among adult recipients., Methods: Twenty-three paediatric to adult EBKTs were performed by the Irish National Kidney Transplant Service between 1990 and 2016. The primary outcome variable was long-term en-bloc allograft survival rate. Secondary outcome variables were incidence of allograft thrombosis, incidence of delayed graft function, overall patient survival and serum creatinine at most recent follow-up. Outcomes were compared to single kidney transplant recipients from the same time period., Results: Mean donor age was 1.8 ± 0.97 years (range: 7 months to 3 years). Recipient age was 46 ± 12 years. Mean follow-up was 133 ± 64 months (range: 36-264). Overall graft survival was 100%, 91% and 80% after 1, 5 and 10 years respectively, compared to 92%, 79% and 61% in single kidney transplant recipients (p = 0.04). There were 5 cases of allograft failure, 3 due to death from unrelated causes. Median time to graft failure was 108 months (range: 36-172). Mean serum creatinine was 72.6 ± 21.6 μmol/l after the follow-up period. There were no cases of graft thrombosis or delayed graft function. Overall survival was 96.4%, 88.0%, 76.23% and 50.5% at 1, 5, 10 and 20 years respectively., Conclusion: En-bloc paediatric kidney transplantation is associated with excellent long-term allograft and patient survival and is a feasible strategy for increasing the transplant donor pool in carefully selected recipients., (Copyright © 2018 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

New oral anticoagulants (NOACs) are increasingly replacing the use of warfarin in clinical practice. Their use has now also been extended to thromboprophylaxis in many orthopedic surgeries. This, in addition to an increasingly aging population with many complex comorbidities means that these medications will be ever more frequently encountered by urologists. Thus, a clear understanding of the mechanism of action of NOACs, their time to peak action and half-life is essential for the purpose of managing these patients perioperatively. This article demonstrates the patient and procedural variability that must be taken into account in the perioperative management of the anticoagulated patient. While the time to peak onset and half-life of NOACs can aid in determining the interval of interruption of anticoagulation, the risks of thrombosis and bleeding must be assessed before the decision to stop anticoagulation. This article takes into account the evidence available on NOACs in urological surgery in order to inform the perioperative management of these medications and to propose guidelines to aid in clinical decision making. In attempting this, we address the issue of the lack of high-level evidence surrounding NOACs in urological surgery given their relative novelty and the need for further research to better guide practice.

Objective: To evaluate the feasibility of a novel "safety-valve" device for preventing catheter related urethral trauma during urethral catheterization (UC). To assess the opinions of clinicians on the performance of the safety-valve device., Materials and Methods: A validated prototype "safety-valve" device for preventing catheter balloon inflation related urethral injuries was prospectively piloted in male patients requiring UC in a tertiary referral teaching hospital (n = 100). The device allows fluid in the catheter system to decant through an activated safety threshold pressure valve if the catheter anchoring balloon is misplaced. Users evaluated the "safety-valve" with an anonymous questionnaire. The primary outcome measurement was prevention of anchoring balloon inflation in the urethra. Secondary outcome measurement was successful inflation of urinary catheter anchoring balloon in the bladder., Results: Patient age was 76 ± 12 years and American Society of Anaesthesiologists grade was 3 ± 1.4. The "safety-valve" was utilized by 34 clinicians and activated in 7% (n = 7/100) patients during attempted UC, indicating that the catheter anchoring balloon was incorrectly positioned in the patient's urethra. In these 7 cases, the catheter was successfully manipulated into the urinary bladder and inflated. 31 of 34 (91%) clinicians completed the questionnaire. Ten percent (n = 3/31) of respondents had previously inflated a urinary catheter anchoring balloon in the urethra and 100% (n = 31) felt that a safety mechanism for preventing balloon inflation in the urethra should be compulsory for all UCs., Conclusion: The safety-valve device piloted in this clinical study offers an effective solution for preventing catheter balloon inflation related urethral injuries., (Copyright © 2018 Elsevier Inc.

Introduction: Male stress urinary incontinence (SUI) after radical prostatectomy (RP) is common. The surgical standard of care traditionally has been placement of an artificial urinary sphincter (AUS) but since its introduction the transobturator male sling has been shown to have particular unique advantages. Our aim was to assess outcomes of a consecutive series of suburethral sling insertions in men presenting with all degrees of post RP SUI., Materials and Methods: A consecutive cohort of men undergoing AdVance sling insertion following RP were studied. Parameters assessed included pre and postoperative urinary function, 24 hour pad use, quality of life (QoL) outcomes, complications and further treatments. Degree of incontinence was categorized as mild (1-2), moderate (3-5) or severe (≥ 6) depending on daily pad use. Patients were reviewed at 1, 4 and 6 months. The International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) was used to assess symptom severity and QoL outcomes., Results: Seventy-seven patients were included, mean age 68 and mean time to sling post RP 34 (8-113) months. Preoperative degree of incontinence: mild 22%, moderate 58%, severe 20%. Fourteen percent had undergone post RP radiation therapy (RT). In total 73% experienced complete resolution of symptoms post sling, 12% significant improvement, 15% no reduction in pad use. Sixty percent with severe incontinence were classified as cured (no pad or 1 dry pad for security reasons). When patients with preoperative RT were excluded, cure rate rose to 82%. On follow up survey at 30 months (mean), the ICIQ-SF score decreased from baseline 17.7 (9-21.0) to 8.0 (0-20) (p < 0.0001), CI 95% (8-12)., Conclusions: Suburethral slings are effective and safe for all degrees of post RP incontinence, are associated with improved QoL parameters and with appropriate selection and counseling are a viable option for more severe degrees of post RP SUI.

Introduction: Rapid Access Prostate Clinics (RAPC) were introduced in Ireland by the National Cancer Control Programme bringing about expedited referral pathways and increased detection rates of prostate cancer. Lower Gleason (G) grade at diagnosis due to RAPC has been previously reported but grade at prostatectomy has not been assessed. The aim of this study was to assess the impact of RAPC on the outcomes of patients with G7 disease on radical prostatectomy (RP)., Methods: A retrospective analysis was carried out of all RPs performed over a 9-year period (2006-2014). Outcomes for G7 prostatectomies were compared before and after the introduction of the RAPC, with a further sub-analysis of G4 + 3 versus G3 + 4. The primary outcome was biochemical recurrence (BCR). Other outcomes were adjuvant/salvage radiotherapy, extra prostatic extension, positive surgical margins, seminal vesicle involvement and tumour stage., Results: In total, 240 RPs were performed with 167 cases graded G7 (70 graded G4 + 3 and 97 graded G3 + 4). Since the introduction of RAPC the proportion of G4 + 3 compared to G3 + 4 has increased from 37.9 to 42%. There was no statistical difference in outcomes for G4 + 3 treated before and after the introduction of RAPC. G4 + 3 was associated with higher rates of BCR (24.4 vs. 0%, p < 0.0001, radiotherapy (41.1 vs. 4.8%, p < 0.0001) and worse histological features than G3 + 4., Conclusion: Despite the benefits in diagnosis of prostate cancer brought about by RAPC in Ireland, this has not translated to a lower grade for surgically treated patients. There has been no improvement in outcomes especially for higher grade G4 + 3 disease.

Introduction and Hypothesis: Hysterectomy is often performed at the time of pelvic organ prolapse (POP) surgery; yet, there is insufficient evidence regarding the specific effect of hysterectomy on outcomes. We sought to determine the outcomes and associated short-term complications of mesh-based POP surgery with and without concurrent hysterectomy., Methods: We utilized the New York Statewide Planning and Research Cooperation System (SPARCS) database to identify patients under 55 years of age undergoing surgeries for POP with mesh between 2009 and 2014. Patients who had a hysterectomy at the time of mesh-based POP surgery were compared with those who underwent mesh-based POP surgery without hysterectomy. Outcome measures of the patient groups before and after propensity score matching were compared. We assessed the difference Chi-squared tests and log-rank tests in the entire cohort and Mantel-Haenszel stratified Chi-squared tests and Prentice-Wilcoxon tests in the matched cohort., Results: A total of 1,601 women underwent mesh-based POP surgery. 921 patients underwent concurrent hysterectomy, whereas 680 had mesh-based uterine-preserving POP surgery. After propensity score matching, there was no difference in reintervention rates between groups for up to 3 years. Concurrent hysterectomy with mesh-based POP repair was consistently associated with longer hospitalization (20.0% vs 12.8% stayed longer than 2 days) and higher charges (median charges were $22,689 vs $19,273)., Conclusions: Concurrent hysterectomy during mesh-based POP surgery in patients under 55 years led to more expensive charges and a longer stay compared with uterine-preserving mesh surgery. There was no difference in reintervention rates between groups for up to 3 years.

Objectives: Urinary incontinence (UI) is a common condition, but despite the availability of guidelines, variations exist in the care of patients. We sought to assess the changes in assessment and management of women with UI over time in the United States., Methods: The National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey are annual surveys from a nationally representative sample of visits to physicians. From 1999 through 2010, we identified visits by women to physicians where the chief complaint was UI using reason-for-visit and International Classification of Diseases, Ninth Revision codes., Results: Using 2-year intervals between 1999-2000 and 2009-2010, the number of visits by women with UI to physicians increased (5.3 million to 6.8 million). There was no difference in patient age, race/ethnicity, or physician specialty (primary care, urology, gynecology). The majority did not have their incontinence characterized (42.4%-47.4%). The use of urinalysis significantly decreased (53%-37.2%, P = 0.02), whereas antimuscarinic use significantly increased (16.7%-35%, P = 0.006). There was an overall increased trend in number of referrals to another physician (5.8%-14.7%, P = 0.06). Urologists had a significant increase in antimuscarinic use (23.5%-44.2%, P = 0.003). All physician specialties demonstrated a decreased trend in use of urinalysis between 1999 and 2010. Although imaging rates were low, they were at highest rates among urologists., Conclusions: The majority of women do not have the type of UI characterized, whereas there is underutilization of urinalysis. Given the widespread prevalence of UI and its implications on quality of life, greater adherence to guidelines is warranted.

Objectives: To compare the surgical outcomes of men with bladder outlet obstruction (BOO) due to benign prostatic obstruction (BPO) to those with detrusor underactivity (DU) or acontractile detrusor (DA)., Materials and Methods: This retrospective, IRB approved study included men who underwent BPO surgery for refractory LUTS or urinary retention. Patients were grouped based on videourodynamic (VUDS) findings: 1) men with BOO, 2) men with DU and 3) men with DA. The primary outcome measure was the Patient Global Impression of Improvement (PGII). Secondary outcome measures included uroflow (Qmax), post-void residual volume (PVR) and the need for clean intermittent catheterization (CIC)., Results: One hundred and nineteen patients were evaluated: 1) 34 with BOO, 2) 62 with DU and 3) 23 with DA. Subjective success rate (PGII) was highest in the BOO group (97%) and those with DU (98%), while DA patients had a PGII success of 26%, (p<0.0001). After surgery, patients with BOO had the lowest PVR (68.5mL). Fifty-six patients (47%) performed CIC pre-operatively (47% of BOO, 32% of DU and 87% of DA patients). None of the patients in the BOO and DU groups required CIC post operatively compared to16/23 (69%) of patients in the DA group (p<0.0001)., Conclusions: BPO surgery is a viable treatment option in men with presumed BOO and DU while DA is a poor prognostic sign in men who do not void spontaneously pre-operatively., Competing Interests: Conflict of interest: None declared., (Copyright® by the International Brazilian Journal of Urology.)

Importance: Mesh, a synthetic graft, has been used in pelvic organ prolapse (POP) repair and stress urinary incontinence (SUI) to augment and strengthen weakened tissue. Polypropylene mesh has come under scrutiny by the US Food and Drug Administration., Objective: To examine the rates of mesh complications and invasive reintervention after the placement of vaginal mesh for POP repair or SUI surgery., Design, Setting, and Participants: This investigation was an observational cohort study at inpatient and ambulatory surgery settings in New York State. Participants were women who underwent transvaginal repair for POP or SUI with mesh between January 1, 2008, and December 31, 2012, and were followed up through December 31, 2013. They were divided into the following 4 groups based on the amount of mesh exposure: transvaginal POP repair surgery with mesh and concurrent sling use (vaginal mesh plus sling group), transvaginal POP repair with mesh and no concurrent sling use (vaginal mesh group), transvaginal POP repair without mesh but concurrent sling use for SUI (POP sling group), and sling for SUI alone (SUI sling group)., Main Outcomes and Measures: The primary outcome was the occurrence of mesh complications and repeated invasive intervention within 1 year after the initial mesh implantation. A time-to-event analysis was performed to examine the occurrence of mesh erosions and subsequent reintervention. Secondary analyses of an age association (<65 vs ≥65 years) were conducted., Results: The study identified 41 604 women who underwent 1 of the 4 procedures. The mean (SD) age of women at their initial mesh implantation was 56.2 (13.0) years. The highest risk of erosions was found in the vaginal mesh plus sling group (2.72%; 95% CI, 2.31%-3.21%) and the lowest in the SUI sling group (1.57%; 95% CI, 1.41%-1.74%). The risk of repeated surgery with concomitant erosion diagnosis was also the highest in the vaginal mesh plus sling group (2.13%; 95% CI, 1.76%-2.56%) and the lowest in the SUI sling group (1.16%; 95% CI, 1.03%-1.31%)., Conclusions and Relevance: The combined use of POP mesh and SUI mesh sling was associated with the highest erosion and repeated intervention risk, while mesh sling alone had the lowest erosion and repeated intervention risk. There is evidence for a dose-response relationship between the amount of mesh used and subsequent mesh erosions, complications, and invasive repeated intervention.

Introduction: Overactive bladder symptoms (OAB) affect 9-43% of women and are associated with underlying disorders, including pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The aim of this study is to identify urogynecological conditions associated with OAB symptoms., Methods: This prospective, institutional review board-approved study included women referred to a tertiary centre with lower urinary tract symptoms (LUTS). All women completed the self-administered OAB questionnaire (OABSS). Those with an OABSS ≥8, the cutoff, were considered to have OAB symptoms. Patients underwent a history and physical examination (including Baden-Walker prolapse grading and stress test), 24-hour voiding diary, pad test (for urinary incontinence), urinalysis, and uroflow with post-void residual volume. Patients were classified clinically into the following: idiopathic OAB, SUI, POP, bladder outlet obstruction (BOO) neurogenic bladder (NGB), recurrent urinary tract infection (UTI), and miscellaneous., Results: In total, 148 women met the inclusion criteria with a mean age of 67 years. Only 27% had no comorbid conditions and were considered idiopathic OAB. Associated urogynecological conditions included SUI in 37%, POP in 26%, miscellaneous conditions in 18%, recurrent UTI in 11%, NGB in 9%, and BOO in 8%. Some patients met criteria for more than one category, thus the total is greater than 100%., Conclusions: In a tertiary care setting, a significant proportion of women with OAB symptoms have underlying conditions that may cause or contribute to their symptoms. Appropriate evaluation is desirable to enhance our understanding of the relationship of these conditions to the diagnosis, treatment, outcomes, and pathophysiology of OAB.

Introduction and Hypothesis: Overactive bladder (OAB) affects a considerable proportion of men and women in the United States and is associated with significant costs and quality of life (QoL) reduction. While medication remains a mainstay of treatment, there is increasing interest in the use of alternative medicine in the form of acupuncture. We reviewed the literature on the role of acupuncture in managing OAB., Methods: A narrative review was compiled after searching electronic databases (PubMed, MEDLINE, Scopus, and EMBASE) for clinical studies involving acupuncture in treating OAB. Databases were searched from the time of inception through September 2015 by a clinician for articles reporting the results related to the use of acupuncture in OAB. Key search terms were acupuncture, overactive bladder, bladder instability, urgency, urinary incontinence. Articles in English or translated into English were included., Results: Initial animal studies suggest several biochemical mechanisms of action underlying the effect of acupuncture on OAB suppression. The experience in humans includes two case series and six comparative trials. All studies demonstrated subjective improvement in OAB symptoms, and some reported objective improvement in urodynamic studies. Notably, some comparative trials showed the benefit of acupuncture to be comparable with antimuscarinic treatment., Conclusion: Despite their limitations, existing studies serve as a promising foundation for suggesting a role for acupuncture as an alternative therapy for OAB. Further well-designed studies are required to investigate optimal technique and their outcomes.

Introduction: In July 2011, the US Food and Drug Administration (FDA) issued a safety communication regarding serious complications associated with surgical mesh for pelvic organ prolapse, prompting increased media and public attention. This study sought to analyze internet search activity and news article volume after this FDA warning and to evaluate the quality of websites providing patient-centered information., Methods: Google Trends™ was utilized to evaluate search engine trends for the term "pelvic organ prolapse" and associated terms between 1 January 2004 and 31 December 2014. Google News™ was utilized to quantify the number of news articles annually under the term "pelvic organ prolapse." The search results for the term "pelvic organ prolapse" were assessed for quality using the Health On the Net Foundation (HON) certification., Results: There was a significant increase in search activity from 37.42 in 2010 to 57.75 in 2011, at the time of the FDA communication (p = 0.021). No other annual interval had a statistically significant increase in search activity. The single highest monthly search activity, given the value of 100, was August 2011, immediately following the July 2011 notification, with the next highest value being 98 in July 2011. Linear regression analysis of news articles per year since the FDA communication revealed r 2  = 0.88, with a coefficient of 186. Quality assessment demonstrated that 42 % of websites were HON-certified, with .gov sites providing the highest quality information., Conclusions: Although the 2011 FDA safety communication on surgical mesh was associated with increased public and media attention, the quality of relevant health information on the internet remains of poor quality. Future quality assurance measures may be critical in enabling patients to play active roles in their own healthcare.

Introduction: In 2010, an estimated 476,076 total PSA tests were performed in Ireland, at a cost of €3.6 million with the majority ordered by general practitioners. We aimed to replicate storage conditions at room temperature and see if prolonged storage affected total and free PSA values., Methods: Blood samples were taken from 20 male patients in four VACUETTE ® Serum Separator tubes (Greiner-Bio-One, Austria) and stored at room temperature (22 °C) for different time intervals (4, 8, 24, 48 h) before being centrifuged and analyzed. Total PSA (tPSA) and free PSA (fPSA) values were determined using the Tosoh AIA 1800 assay (Tokyo, Japan)., Results: Mean tPSA values were measured at 4, 8, 24 and 48 h with values of 7.9, 8.1, 7.8 and 8.0 μg/L, respectively. Values ranged from -1.26 to +2.53 % compared to the initial 4 h interval reading, indicating tPSA remained consistent at room temperature. The tPSA showed no significance between groups (ANOVA, p = 0.283). Mean fPSA values at 4, 8, 24 and 48 h were 2.05, 2.04, 1.83, 1.82 μg/L, respectively. At 24 and 48 h there was 10.73 and 11.22 % reduction, respectively, in fPSA compared to the 4-h time interval, indicating prolonged storage resulted in reduced fPSA values. After 24 h, there was an 8.8 % reduction in the free/total PSA %. The fPSA showed significant differences between groups (ANOVA, p = 0.024)., Conclusions: Our recommendation is that samples that have been stored for prolonged amounts of time (greater than 24 h) should not be used for free PSA testing.

Introduction: The GreenLight™ XPS Laser System (GL-XPS) is a safe and efficacious treatment for lower urinary tract symptoms due to benign prostatic hyperplasia (BPH), but there is limited evidence on its use in prostates over 150 mL. We demonstrate the safety and efficacy of the GL-XPS system using a vapoenucleation technique in prostate glands measuring over 150 mL., Methods: We prospectively collected data on all consecutive patients with prostates measuring over 150 mL on transrectal ultrasound treated with the GL-XPS (AMS, Inc., Minnetonka, MN) at a tertiary referral center from September 2011 to October 2015. Data collected include prostate volume, International Prostate Symptom Score (IPSS) and quality of life (QoL) scores, maximum urinary flow rate (Qmax), postvoid residual (PVR), prostate-specific antigen, complications, and reintervention rates., Results: Seventy male patients with a median prostate size of 202 mL (range 152-376 mL) were included. There were 41 patients (59%) in preoperative urinary retention with an indwelling catheter preoperatively. Thirty-seven (53%) patients were American Society of Anesthesiologists (ASA) class 2 and 33 (47%) were class 3. Median operative time was 180 minutes, laser time 97 minutes, energy utilization 674 kJ, and energy density 3.3 kJ/mL, with median 3 fibers used per case. Median length of stay and length of catheterization were 1 day. IPSS and QoL scores demonstrated significant improvements from baseline at all endpoints, improving from 16 to 3.5 and from 4 to 1 at 24 months, respectively (p = 0.001). At 12 months, Qmax and PVR improved from 10.1 to 22.4 mL/s (p = 0.043) and from 84 to 31.4 mL (p = 0.015), respectively. Retreatment was required in two patients (2.9%)., Conclusion: GL-XPS vapoenucleation provided durable subjective and objective improvements in symptoms and voiding parameters, with no serious adverse events in men with prostates >150 mL.

Benign prostatic hyperplasia (BPH), which causes lower urinary tract symptoms (LUTS), is a common diagnosis among the ageing male population with increasing prevalence. Many risks factors, both modifiable and non-modifiable, can increase the risk of development and progression of BPH and LUTS. The symptoms can be obstructive (resulting in urinary hesitancy, weak stream, straining or prolonged voiding) or irritative (resulting in increased urinary frequency and urgency, nocturia, urge incontinence and reduced voiding volumes), or can affect the patient after micturition (for example, postvoid dribble or incomplete emptying). BPH occurs when both stromal and epithelial cells of the prostate in the transitional zone proliferate by processes that are thought to be influenced by inflammation and sex hormones, causing prostate enlargement. Patients with LUTS undergo several key diagnostic investigations before being diagnosed with BPH. Treatment options for men with BPH start at watchful waiting and progress through medical to surgical interventions. For the majority of patients, the starting point on the treatment pathway will be dictated by their symptoms and degree of bother.

Objective: The objective of this study is to investigate the combination effect of anti-muscarinic medication and topical vaginal estrogen in the treatment of overactive bladder (OAB) and female sexual dysfunction in postmenopausal women., Study Design: After IRB approval, 23 female subjects who met the entry criteria were randomized into two groups: (1) fesoterodine (Toviaz®, Pfizer, NY) with topical vaginal estrogen (Premarin®, Pfizer, NY) once daily or (2) fesoterodine once daily alone. If 4 mg fesoterodine was tolerated at 1-week, the dose was increased to 8 mg., Main Outcome Measures: Primary endpoints were improvement in OAB symptom severity (Overactive Bladder Questionnaire, OAB-Q SF), improvement in OAB health-related quality of life (HRQL) (OAB-Q SF), and sexual function (Sexual Quality of Life-Female, SQOL-F) after 12 weeks. Secondary endpoint was change in total number of micturitions., Results: After 12-weeks, the combination group had a significant improvement in OAB symptom severity (p = 0.006), HRQL (p = 0.029), and SQOL-F (0.0003). The fesoterodine alone group also had significant improvement in OAB symptom severity (p < 0.0001), HRQL (p = 0.0002), and SQOL-F (p = 0.02). When compared directly to the fesoterodine alone group, the combination group after 12-weeks had a reduced OAB symptom severity (10 versus 23.3; p = 0.35), higher HRQL (96.9 versus 84.6; p = 0.75), and higher SQOL-F (99 versus 81; p = 0.098). The total number of micturitions over 3 d was significantly reduced in the combination group (45-26, p = 0.03) between baseline and 12-weeks., Conclusions: The combined effect of fesoterodine and topical vaginal estrogen improved OAB symptoms and sexual function in postmenopausal women., (© The Author(s) 2016.)

Introduction: Kidneys from extended criteria donors are associated with higher rates of delayed graft function (DGF). Hypothermic machine perfusion (MP) for storage is associated with more favourable outcomes., Methods: A retrospective analysis was performed in 93 patients where the kidney was stored using hypothermic MP (LifePort(®)) and compared to an age-matched control group where the kidney was stored in cold static storage (CSS) using University of Wisconsin solution., Results: Median age was similar in both groups (59.2 years in MP vs 59.9 years in CSS, p = 0.5598). Mean cold storage time was 15.6 h in MP vs 17.9 h in CSS. Post transplant mean serum creatinine was as follows; MP group-144.7 μmol/L at 1 month; 138.3 μmol/L at 3 months and 129.5 μmol/L at 12 months. In the CSS group-163 μmol/L at 1 month; 154.9 μmol/L at 3 months and 140.2 μmol/L at 12 months. There was a statistically significant difference at 1 month (p = 0.0096) and 3 months (p = 0.0236). DGF was defined as the need for haemodialysis within 7 days post transplant. In the MP group, DGF occurred in 17.2 % patients with mean of 6 days (range 1-18). In the CSS group, 25.8 % patients with mean of 8.1 days (range 3-25). One-year graft survival rate was better in the MP group (97.85 vs 96.77 %)., Conclusion: Our experience to date recommends the use of hypothermic MP for storage of kidneys from extended criteria deceased heart-beating donors.

The transobturator tape (TOT) is an effective treatment for stress urinary incontinence (SUI). Erosion of TOT mesh is a recognised complication requiring excision. A retrospective analysis of 228 females undergoing a TOT procedure over 4 years identified 16 patients (7%) that underwent excision of eroded mesh. Mean age of patients requiring excision was 48.8 years and mean weight was 72.7kg. Mean time to re-presentation was 14.5 months. Presenting symptoms included dyspareunia in 9 patients (56.2%), dysuria in 3 (18.7%), persistent incontinence in 3 (18.7%) and groin pain in one patient. Ten patients (62.5%) had a prior urogynecological procedure. After excision of eroded tape-mesh, 7 (43.7%) required a rectus fascial sling and 4 (25%) underwent repeat TOT for recurrence of SUI. Five patients (31.2%) required no further surgery. At present 10 patients (62.5%) report resolution of SUI, 4 (25%) report mild SUI and 2 (12.5%) patients have moderate/severe SUI. Resolution of symptoms occurred in the majority of patients after excision of eroded mesh and an additional anti-incontinence procedure.

Introduction: Urology cover is commonly available out-of-hours in most teaching hospitals. However, increased pressure to reduce hospital expenditure has forced many institutions to consider removing middle grade cover outside of normal working hours. The aim of this study was to audit the emergency urology activity in our institution over a 12-month period., Methods: A prospective logbook was maintained for all urology referrals from the emergency department between August 2012 and March 2013. The diagnosis and patient outcome was recorded for each referral. The emergency theatre logbook was retrospectively evaluated for all emergency urology procedures carried out over the same time period. A basic cost analysis was performed to calculate the cost of providing the on-call service., Results: A total of 752 patients were referred to the urology service over a 12-month period. The most common reasons for referral were renal colic and scrotal pain. Approximately 41 % of referrals were discharged directly from the emergency department. There were 167 emergency operations performed in total. The majority of emergency operations and referrals from the emergency department took place outside of normal working hours. A basic cost analysis revealed an associated cost saving of €58,120., Conclusion: Emergency urology activity constitutes a large proportion of the workload at our institution. Restricting emergency urology cover would limit essential training opportunities for urology trainees, increases length of stay and delay treatment of urological emergencies. Urology "out of hours" cover is a cost-efficient method of service provision.

Objective: Successful management of a contrast reaction requires prompt recognition and treatment and effective team dynamics among radiologists, technologists, and nurses. A radiology department implemented a simulation program in which teams of nurses, technologists, and physicians managed simulated contrast reactions. The purpose of this study was to evaluate whether simulation improved the participants' abilities to manage a contrast reaction and work in a team during an emergency., Subjects and Methods: Physicians, nurses, and technologists worked in inter-professional teams to manage two high-fidelity simulated adverse contrast reactions. Participants completed surveys before and after the simulation that included knowledge-based questions about the appropriate management of contrast reactions. Surveys also included questions for assessing participants' perceptions of their ability to manage adverse contrast reactions, measured with a 6-point Likert scale. Before and after comparisons were made with the McNemar test with a Bonferroni correction requiring p ≤ 0.003 for significance. For the other analyses, p ≤ 0.05 was considered significant., Results: After completion of the simulation exercises, participants had significant improvement in knowledge (p < 0.001). After the simulation, participants reported significant improvement in their ability to manage an anaphylactoid reaction and their ability to work in a team (p < 0.00001). Participants requested repeat simulation exercises every 6-12 months., Conclusion: Simulation exercises improved the self-reported ability of radiology personnel to manage contrast reactions and work in a team during an emergency. Simulation should be incorporated into future educational initiatives to improve patient safety in radiology practices.

Objective: To assess the impact of a structured training programme in urethral catheterisation (UC) targeted at newly qualified junior doctors on rates of iatrogenic catheter morbidity within a tertiary care referral centre., Subjects and Methods: Male UC-related morbidities were retrospectively identified from our computerised inpatient urology consultation system over a 1-year period from July 2010 to June 2011. Relevant medical records were also reviewed. Results were compared with an initial study performed between July 2006 and June 2007, prior the introduction of a structured training programme in our institution. An anonymous questionnaire was used for the subjective assessment of interns about confidence in catheterising post introduction of the programme., Results: Of 725 urological consultations, 29 (4%) were related to complications arising from male UC during the 1 year period. This reflected a statistically significant decrease when compared to our 2007 figures, 51/864 (6%) (p < 0.05). Again, the most common indication for UC was monitoring urinary output for acute medical illness (19/29, 66%). The most common complication was urethral trauma (16/29, 55%). Of the 29 cases of UC-related morbidity, 18 (62%) resulted from interns performing UC, a decrease of 12% from our original paper. A drop of 27% was seen in the rates of UC related morbidity attributable to interns during the first 6 months of internship (July-December). Overall, 70% (vs 40% original study) of interns felt that their practical training was adequate since introduction of the programme (p < 0.01) with 53% considering theoretical training adequate (vs 16% original study (p < 0.01). When asked were they confident in performing UC, 63% said they were compared to 35% before introduction of the programme (p < 0.05)., Conclusions: UC-related iatrogenic morbidity is not uncommon even in a tertiary-care teaching hospital. Implementation of a structured training programme in UC prior to the commencement of intern year has been shown to result in a significant decrease in the amount of iatrogenic UC related morbidity., (Copyright © 2014 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Introduction: Active surveillance (AS) is a management strategy for addressing the widely acknowledged problem of over diagnosis and over treatment of clinically indolent prostate cancer., Methods: A total of 80 patients were enrolled on the AS program in our institution between January 2008 and June 2012. All data were collected prospectively in a secure database., Results: The mean age of patients enrolled was 62.7 years (range 50-72). Median PSA at enrolment was 5.6 ng/mL (range 1.2-13.4). The mean follow-up was 32 months (range 2-54). In total, 85 % of patients had a repeat biopsy after 1-year with 30 % having another biopsy after 3 years. Overall, 45 % of patients remain on AS. In the remainder; 42.5 % of patients have been removed from AS for definitive treatment, while 8.75 % of patients are now on watchful waiting, 2.5 % of patients self discharged from the program and one patient died of cardiovascular disease. The prostate cancer specific survival rate is 100 %. Reasons for removal from AS and referral for treatment were; 67.6 % of patients had upgrade of disease on repeat biopsy, 17.6 % of patients had PSA progression, 11.8 % patients had progression of disease on MRI, and one patient developed a palpable nodule. Regarding definitive treatment; 52.9 % of patients have been for referred for external beam radiotherapy, 14.7 % have been referred for brachytherapy, 29.4 % have been referred for surgery and one patient has refused definitive treatment., Conclusion: Our findings to date support active surveillance as a valid strategy for early, localised prostate cancer.

Many cosmetic procedures are now performed by non-medical personnel. Owing to the wide coverage of aesthetic procedures by the media, patients may be less informed of the serious complications that can be seen when impure materials are injected by less-skilled practitioners. The authors present a case of sepsis following the injection of a non-medical grade penile bulking agent. Although penile augmentation is under-reported in the literature, public interest in such procedures is increasing. The growing demand for such procedures needs to be addressed by the medical community.

Renal artery aneurysms (RAA) are the second most common visceral artery aneurysm. In cases of rupture they pose a significant and emergent surgical challenge. Extracorporeal arterial reconstruction and autotransplantation is often necessary in certain complex cases that are not amenable to aneurysm repair in vivo. We report a case of a 35 year old female with a RAA in a solitary functioning kidney, requiring ex vivo reconstruction and autotransplantation to the iliac vessels.

Introduction: Our institution is a 680-bed tertiary referral centre with broad medical and surgical subspecialty services. We retrospectively audited the pattern of inpatient consultations from all specialities within our institution to the urology department over a 1-year period., Methods: All consultations to the urology service were identified from our computerised inpatient consultation system from July 2010 to June 2011. Follow up data on investigations, interventions and subsequent outpatient appointments were also identified by review of individual patient discharge letters., Results: Seven hundred and twenty five inpatient consultations were received over the period. The male to female ratio was 7:3. Mean age of patients was 66 (15-96) years. Seventy three percent of referrals were from medical sub-specialities, most commonly nephrology (17%), gastroenterology (11%) and respiratory medicine (9%). The remainder were from general surgery (16%) and other surgical sub specialities (11%). Interns (66%) and senior house officers (SHO) (28%) communicated the majority of consults. Male lower urinary tract/benign prostate related issues resulted in 25% of all consultations. Less than half of consults (47%) resulted in interventions initiated by urology, most commonly of which were catheter insertions (48%) and endoscopic procedures (35%). Only 43% of consultations were followed up in the outpatients setting., Conclusions: Inpatient consultations constitute a significant workload for urology services. The majority of these referrals did not require any urological intervention and could have been seen routinely in the outpatient setting. Providing structured referral guidelines and achieving better communication with referring teams may help to optimise this service., (Copyright © 2013 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Seminoma is the most common single histological sub-type of testicular carcinoma. Patients usually present with a painless lump and stage I disease. We describe a case of an incidental meta-static seminoma in a 28-year-old man post-renal trauma with a dramatically elevated β-human chorionic gonadotropin (βHCG). His βHCG level has returned to normal post-orchidectomy and chemotherapy.

Introduction: Urethral strictures constitute a significant clinical problem that often requires long-term management., Objective: To report the long-term outcomes of adjuvant home self-urethral dilatation of recurrent urethral strictures using a balloon catheter., Materials and Methods: Male patients (N = 11), performing self-dilatation with a balloon catheter (minimum 24 months) were assessed by patient-reported outcome measures (PROMs) health questionnaire specific for post treatment assessment of men with urethral stricture disease., Results: Median duration of balloon catheter use is 46.5 months, IQR (24-150). Patients performed self-balloon dilatation on average 1.4 times a week, median 1, IQR (1-2) to maintain the patency of their urethra. The mean PROMs LUTS score of the patients was 2.45, median 2, IQR (1-4). The median and mean Peeling score was 2 IQR (1-2). 100 % patient reported that they either very satisfied or satisfied with the overall outcome and QoL., Conclusions: Our initial experience of outpatient self-dilatation with a balloon dilatation is encouraging and is an acceptable inexpensive and simple treatment for patient maintains urethral patency and potentially decreases stricture recurrence.

Objective: The efficacy of docetaxel has recently been shown to be increased under hypoxic conditions through the down-regulation of hypoxia-inducible-factor 1α (HIF1A). Overexpression of the hypoxia-responsive gene class III β-tubulin (TUBB3) has been associated with docetaxel resistance in a number of cancer models. We propose that administration of docetaxel to prostate patients has the potential to reduce the hypoxic response through HIF1A down-regulation and that TUBB3 down-regulation participates in sensitivity to docetaxel., Methods: The cytotoxic effect of docetaxel was determined in both 22Rv1 and DU145 prostate cancer cell lines and correlated with HIF1A expression levels under aerobic and hypoxic conditions. Hypoxia-induced chemoresistance was investigated in a pair of isogenic docetaxel-resistant PC3 cell lines. Basal and hypoxia-induced TUBB3 gene expression levels were determined and correlated with methylation status at the HIF1A binding site., Results: Prostate cancer cells were sensitive to docetaxel under both aerobic and hypoxic conditions. Hypoxic cytotoxicity of docetaxel was consistent with a reduction in detected HIF1A levels. Sensitivity correlated with reduced basal and hypoxia-induced HIF1A and TUBB3 expression levels. The TUBB3 HIF1A binding site was hypermethylated in prostate cell lines and tumor specimens, which may exclude transcription factor binding and induction of TUBB3 expression. However, acquired docetaxel resistance was not associated with TUBB3 overexpression., Conclusion: These data suggest that the hypoxic nature of a tumor may have relevance as regard to their response to docetaxel. Further investigation into the nature of this relationship may allow identification of novel targets to improve tumor control in prostate cancer patients., (Copyright © 2012 Elsevier Inc.

Unlabelled: What's known on the subject? and What does the study add? Today, numerous assays for PSA detection are available from various manufacturers. However, these various assays do not detect PSA equally and several studies have demonstrated variability between them. In order to harmonise PSA results and reduce the discrepancies, reference materials are available for assay calibration. We have demonstrated significantly variability between 6 different assay methods currently in use in 9 hospitals despite assay calibration. Variability in PSA values was reduced with the standardisation of the assay method in 4 hospitals. Our results highlight the dilemma of PSA assay variability and stress the need for nationwide standardisation of PSA testing., Objective: To determine whether standardization of total prostate-specific antigen (tPSA) assay methods reduces variability in tPSA measurements., Patients and Methods: Blood samples from 84 patients attending a single urology department were distributed across nine hospitals selected throughout Ireland for the independent determination of tPSA under the same conditions. The selected hospitals collectively used six different assay methods for tPSA detection: Beckman Hybritech WHO Calibrated (used as reference method), Tosoh AIA 1800, Roche E170 (used in three hospitals), Abbott AxSYM, Immulite 2500 2nd Generation (used in two hospitals) and Siemens ADVIA Centaur. The method of tPSA detection was next standardized in a subset of four hospitals using the same assay method and the measurements were repeated. The difference in mean tPSA in the cohort across the hospitals tested was determined and the Bland-Altman test was used to assess the agreement between each test. Analysis was performed over both the full (0.5-30 µg/L, N = 84) and a narrow (3-7 µg/L, n = 25) tPSA range., Results: The range and the mean tPSA of the full cohort were inflated across the eight test hospitals, when compared with the reference hospital. The poorest agreement between assay methods was associated with a bias of 2.2 ± 2.4 µg/L. The variability in tPSA measurements between assay methods was inconsistent across the range of tPSA values tested and increased with increasing mean tPSA. Agreement in reported tPSA was excellent after standardization of tPSA assay methods (bias <0.2 µg/L). Over the narrow 3-7 µg/L PSA range, 12/25 (48%) patients had a tPSA range of values across all hospitals in excess of 2 µg/L. Following standardization of the tPSA assay method, patient tPSA ranges were <0.5 µg/L for 13/25 (52%) patients., Conclusions: We have shown that the lack of standardization of tPSA assay methods across a panel of Irish hospitals leads to significant variability in the measured tPSA values for the same patient samples. Variability in tPSA values was reduced with the standardization of the assay method in four hospitals. Standardization of PSA testing on a nationwide scale is warranted., (© 2012 BJU INTERNATIONAL.)

This case highlights the need for cautious management and serial regular examination of trauma patients. A 22-year-old Caucasian male presented to the emergency department 4 h following an injury sustained during football training. He complained of the immediate onset of severe left upper quadrant and left flank pain. He subsequently developed frank haematuria. On initial review, he was haemodynamically stable. CT of the abdomen and pelvis showed a grade 4 renal trauma. Over the following 36 h, he remained haemodynamically stable. On serial abdominal examinations however, he developed a rigid abdomen and was noted to have a haemoglobin drop. Interval CT scan showed a progression of his injury and the presence of a haemoperitoneum. An emergency laparotomy was performed resulting in a left nephrectomy. He made an uneventful recovery.

Background: The National Cancer Control Programme is developing standards for access to diagnostics and treatment of prostate cancer. The Rapid Access Prostate Cancer (RAPC) clinic in St. James's Hospital commenced in May 2009 allowing general practitioners (GPs) more streamlined access for patients., Aims: To demonstrate that RAPC clinics allow GPs direct access to a designated cancer centre improving the prostate cancer referral process. This ultimately should reduce referral delays., Methods: A prospective analysis of all patients referred to the RAPC clinic in St. James's Hospital over a 12-month period beginning from May 2009., Results: Over the 12-month period 215 patients were referred to the RAPC clinic. The median age was 63 years (range 45-78). The median waiting time between referral and review at the RAPC clinic was 13 days (range 1-37). The median PSA was 7.7 μg/L (range 2.6-150). In total 199 TRUS biopsies were performed, of which 46% were positive for prostate cancer. We found that 70% of all patients had a PSA ≤ 10 μg/L and of these 32% were positive for prostate cancer. For the remaining 30% of patients who had a PSA > 10 μg/L, we found 63% were positive for prostate cancer. Regarding patients diagnosed with prostate cancer 56% have been referred for radiotherapy, 13% for surgery, 13% for hormonal treatment, 10% for active surveillance and 8% watchful waiting., Conclusion: RAPC clinics allow GPs easier access to specialist urological opinion for patients suspected of having prostate cancer.

Background: We proposed to investigate the radiosensitizing properties of PBOX-15, a novel microtubule-disrupting agent, in a panel of cancer cell lines., Results: PBOX-15 treatment was associated with significant cell kill and increased radiosensitivity in all three cell lines tested. The number of surviving cells in response to the combined treatment was significantly less than PBOX -15 alone in 22Rv1 cells. In these cells, radiosensitisation correlated with induction of G2/M cell cycle arrest by PBOX-15. The compound sustained its activity and increased HIF-1Α expression under hypoxic conditions. PBOX-15 prevented onset of hypoxia-induced radioresistance in hypoxic prostate cells and reduced the surviving fraction of irradiated hypoxic cells to levels similar to those achieved under aerobic conditions., Methods: Clonogenic assays were used to determine sensitivity of a panel of cancer cell lines (22Rv1, A549, U87) to PBOX-15 alone or in combination with a single 2Gy dose fraction. Induction of cell cycle arrest and apoptosis was investigated in 22Rv1 prostate cancer cells. The cytotoxic properties of the compound under hypoxic conditions were correlated with Hypoxia Inducible Factor 1 alpha (HIF-1Α) gene and protein expression levels and its radiosensitisation potential was investigated in hypoxic 22Rv1 using clonogenic assays., Conclusions: This preliminary data identifies the potential of PBOX-15 as a novel radiosensitising agent for the management of solid tumours and eradication of hypoxic cells.

The ileal conduit continues to be the most common form of urinary diversion performed worldwide. As a result of improved surgical technique the perioperative mortality and morbidity for patients undergoing ileal conduit urinary diversion has reduced remarkably. However, one early complication that may occur is that of urinary leak at the ileo-ureteric anastomosis. Urinary anastomotic leaks may be associated with significant morbidity and mortality. Although a small initial leakage postoperatively is common, the problem arises in cases of continued urinary leakage from the ileo-ureteric anastomosis. We report the management of a persistent ileo-ureteric anastomotic leak using angioplasty balloons catheters to occlude both ureters.

Delayed presentation of a brachial artery pseudoaneurysm following penetrating trauma is infrequently reported. We report the case of a 23-year-old male who presented three months following a penetrating trauma to his antecubital fossa with a sudden exacerbation of swelling and tenderness of his elbow. Doppler ultrasound and computed tomography arteriography confirmed the presence of a large pseudoaneurysm. Surgical reconstruction was performed using the long saphenous vein as an interposition vein graft, restoring normal arterial circulation.
