Oxybutynin is an important anticholinergic agent that prevents uncontrolled contractions in the treatment of overactive bladder (OAB). However, drugs containing oxybutynin have significant side effects such as dry eyes, dry mouth, increased heart rate, constipation, blurred vision, and confusion. In recent years, new delivery methods for this agent are being searched. One of them is vaginal delivery. In this study, we aimed to compare the effects of oxybutynin on oxidative parameters in the potential target tissues of the oral and vaginal delivery. Female New Zealand white rabbits (n=12) were divided into two groups: oral delivery and vaginal delivery. The animals were sacrificed 48 h after administration and nitric oxide (NOx), thiobarbituric acid-reactive substances (TBARs), and glutathione (GSH) levels were determined spectrophotometrically in the aorta, salivary gland, and small intestine tissue samples. Vaginal delivery significantly decreased NOx levels in all tissue samples as compared to oral delivery (p < 0.05). Moreover, it reduced TBARs levels in salivary gland and aorta tissue samples (p < 0.05). In the light on these findings, it can be said that vaginal delivery may decrease the oxidant-induced side effects of oxybutynin as compared to oral delivery.

Surgical site infection rates remain a common postoperative problem that continues to affect patients undergoing urologic surgery. Our study seeks to evaluate the difference in surgical site infection rates in patients undergoing open radical cystectomy when comparing the Bookwalter vs. the Alexis wound retractors. After institutional review board approval, we performed a retrospective chart review from February 2010 through August 2017 of patients undergoing open radical cystectomy with urinary diversion for bladder cancer. We then stratified the groups according to whether or not the surgery was performed with the Alexis or standard Bookwalter retractor. Baseline characteristics and operative outcomes were then compared between the two groups, with the main measure being incidence of surgical site infection as defined by the CDC. We evaluated those presenting with surgical site infections within or greater than 30 postoperatively. Of 237 patients who underwent radical cystectomy with either the Alexis or Bookwalter retractor, 168 patients were eligible to be included in our analysis. There was no statistical difference noted regarding surgical site infections (SSIs) between the two groups; however, the trend was in favor of the Alexis (3%) vs. the Bookwalter (11%) at less than 30 days surgery. The Alexis wound retractor likely poses an advantage in reducing the incidence in surgical site infections in patients undergoing radical cystectomy; however, multicenter studies with larger sample sizes are suggested for further elucidation.

Introduction: To compare (1) the quality of prostate cancer health information on the Internet, (2) the difference in quality between websites appearing earlier or later in the search, and (3) the sources of sponsorship for each of these websites.

Materials and methods: The top 150 listed websites on the Google search engine for each of the 11 search terms related to prostate cancer were analysed. Quality was assessed on whether the website conforms to the principles of the Health On the Net Foundation. Each of these websites was then reviewed to determine the main source of sponsorship. Statistical analysis was performed to determine if the proportion of HON accreditation varied among the different cohorts of listed websites and among the 11 search terms used.

Results: In total, 1650 websites were analysed. Among these, 10.5% websites were HON-accredited. The proportion of HON-accredited websites for individual search terms ranged from 3.3% to 19.3%. In comparison with the search term of "Prostate cancer," four search terms had statistically significant odds ratio of the rate of HON accreditation. Websites 51-150 were statistically less likely to have HON accreditation than websites 1-50. The top three website sponsors were journal/universities (28.8%), commercial (28.1%), and physician/surgeon (26.9%).

Conclusions: The lack of validated and unbiased websites for prostate cancer is concerning especially with increasing use of the Internet for health information. Websites sponsored or managed by the government and national departments were most likely to provide impartial health information for prostate cancer. We need to help our patients identify valid and unbiased online health resources.

Background: A combined urology clinic staffed by four consultants and four non-consultant hospital doctors (NCHDs) was introduced in our institution in October 2015. This clinic is supported by a pre-clinic radiology meeting and a synchronous urology clinical nurse specialist (CNS) clinic with protected uroflow/trial of void slots. Herein, we report on the outcomes of this clinic in comparison with the standard format of urology outpatient review.

Methods: We carried out a retrospective review of clinic attendances from May to July 2016. We recorded the number of new and return attendances, which team members had reviewed the patient and patient outcomes. We also calculated the waiting times for new patients to be reviewed in the outpatient clinic.

Results: The combined urology clinic reviewed an average of 12 new and 46 return patients per clinic. The standard urology clinic reviewed an average of 8 new and 23 return patients per clinic. 54% of patients were seen by a consultant in the combined urology clinic, and 20% of patients were seen by a consultant in the standard urology clinic. The rate of patient discharge for new patients was 14.8% in the combined clinic compared to 5.9% in the standard clinic. Overall patient outcomes are outlined in the table. The waiting time for review of new patients in the combined clinic was reduced by 39% from 144 days to 89 days over a one-year period.

Conclusions: The introduction of a combined urology outpatient clinic with the support of pre-clinic radiology meeting and synchronous urology CNS clinic facilitates patient discharge.

Objective: To assess the learning curve in robot-assisted radical prostatectomy (RARP) performed by surgeons without previous experience in laparoscopic prostatectomy.

Materials and methods: We analyzed 119 patients submitted to RARP performed by two surgeons without previous experience in laparoscopic prostatectomy, with emphasis on the relevant outcomes such as continence, erectile function, and oncologic control with a minimum follow-up of 24 months. We used Fisher's exact test and the chi-square test to investigate the existence of a relationship between the variables and analysis of variance (ANOVA) to verify possible statistically significant differences between groups, at the 5% level.

Results: The patients' age varied from 41 to 72 years (mean = 61.09), with 68 (57.14%) cases having intermediate or high risk. There was a consistent decline in operative time. Of the 119 patients, 80.67% were continent 6 months after surgery and 89.07% 12 months afterward, while 35.29% were potent 6 months after surgery and 60.50% 12 months following surgery. Twelve months after surgery, the trifecta outcome rate was 51.26% and the pentafecta rate was 31.09%. There was progressive postoperative improvement and maintenance of continence and sexual potency until the last patient was operated in our sample.

Conclusions: Robot-assisted radical prostatectomy does not require previous experience in laparoscopic radical prostatectomy, but the learning curve is not short to achieve the plateau.

Background: Cryptorchidism or undescended testes is the most common disorder of the male endocrine glands in children. With the advancements in laparoscopic techniques and instruments, laparoscopic orchidopexy has become the standard procedure in the management of nonpalpable undescended testes.

Aim: To evaluate and determine the therapeutic role, sensitivity, and specificity of laparoscopy in localizing nonpalpable testes and the mean operative time, the conversion rate (and reasons thereof), postoperative wound infection, postoperative stay, and time taken for return to daily activities following laparoscopic orchidopexy or orchidectomy.

Materials and methods: This was a prospective study carried out in the Postgraduate Department of Surgery, Government Medical College, Srinagar, J&K, India, from May 2008 to August 2011. All patients who presented to the outpatient department with complaints of absent testes were examined, and the ones with nonpalpable testes were included in the study.

Results: The mean operative time for bilateral and unilateral nonpalpable testis was 102.76 and 53.67 minutes, respectively. Minor postoperative wound infections were noted in 4 of our patients. Mean duration of hospital stay was 14.23 hrs for unilateral cases and 16.27 hrs for bilateral cases. Patients who underwent laparoscopic orchidopexy resumed their normal activities within 4 ± 1 days.

Conclusion: Laparoscopy clearly demonstrates the anatomy and provides visual information upon which a definitive decision can be made for further management of the undescended nonpalpable testis.

Introduction: Vesicoureteral reflux (VUR) is a common urologic anomaly in children. Many techniques have been offered to manage this condition, in which one of them is modified Gil-Vernet antireflux surgery. The study fullfiled to evaluate the efficacy and safety of modified Gil-Vernet antireflux surgery in correction of high-grade VUR.

Materials and methods: A retrospective study in which we evaluated efficacy, safety, and complications of modified Gil-Vernet antireflux surgery as a choice procedure for high-grade reflux in all patients who underwent it since 2000 to 2016 at 2 hospitals of Kermanshah University of medical sciences that all of them were done by one surgeon.

Results: 183 patients with 290 high-grade refluxing units (grade IV or V) were reviewed. 182 refluxing units were grade IV, and 108 units were grade V. There were 76 (41.54%) patients with unilateral and 107 (58.46%) patients with bilateral VUR. Reflux in high-grade group corrected completely in 278 (95.86%) refluxing units and 175 patients (95.62%).

Conclusions: Our results are remarkable and compatible with other techniques' results. This simple and safe technique can correct bilateral VURs simultaneously; thus, it is rational to be considered for high-grade VUR correction. According to our results, we suggest the modified Gil-Vernet antireflux procedure for high-grade VUR correction as a simple, safe, and successful technique. This trial is registered with 67145/86/1233.

Objectives: Evaluation of changes in symptoms among patients with overactive bladder syndrome treated with transdermal oxybutynin and tolerability after 12 months of follow-up.

Methods: This was a multicenter, retrospective, single-cohort, observational study. Changes in symptoms were evaluated primarily with a 3-day voiding diary. Results were compared to baseline. Subgroup analyses were performed in patients previously treated for OAB or not and aged < 65 years versus ≥65 years.

Results: Clinical records of 105 patients were examined; 92.4% were women. At 12 months, 58 patients continued to receive transdermal oxybutynin. Changes in symptoms according to the voiding diary were evaluated in 47 patients. Significant improvements from baseline were observed in urinary frequency (-2.6 voids/24 hours (95% CI: -3.5; -1.8), p < 0.001); daily number of urgent episodes (-4.7 episodes/day (95% CI: -6.1; -3.6), p < 0.001); and urge incontinence (-1.9 episodes/day (95% CI: -2.9; -1.3), p < 0.001). No statistically significant differences were found in subgroup analyses. In total, 38.1% of patients had adverse events, primarily in the application site (27.6%). No severe systemic adverse events occurred. Only 6 patients (5.7%) reported dry mouth.

Conclusions: Improved symptoms and good tolerability observed after 1 year of treatment with transdermal oxybutynin shows that it currently has a place in the treatment of OAB patients.
