Nephrolithiasis accelerates the renal failure in the patients with ADPKD. In order to evaluate the role of percutaneous nephrolithotomy in management of calculus in these patients, 11 patients with autosomal dominant polycystic kidney disease and renal stones were included in the study. Two patients had bilateral renal stones. All patients were treated by percutaneous nephrolithotomy under ultrasound guidance. 13 percutaneous nephrolithotomy procedures were performed in 1 stage by the urology team under ultrasound guidance. 5 people received second operation with flexible nephroscopy in lateral position. The success rate and morbidity and mortality of the technique and hospital stay were recorded. Results. The puncture procedure was fully successful in all cases. The renal function improved in these patients. 5 patients had moderate fever after the surgery. 5 patients received flexible nephroscopy to take out the residual calculi. 2 persons had ESWL therapy after the surgery. Conclusion. PCNL is an ideal, safe, and effective method to remove the stones from those patients with no definite increase in the risk of complication. The outcome and stone-free rate are satisfactory comparable to the PCNL in the patients without ADPKD.

Objectives: The persistence of silodosin and the reasons for withdrawal from treatment of previously untreated Japanese patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) were evaluated in real-life clinical practice.
Methods: A total of 81 previously untreated Japanese patients diagnosed with LUTS/BPH were treated with silodosin monotherapy and prospectively followed for 4 years. The persistence rate was estimated using the Kaplan-Meier method. If silodosin had to be terminated or a patient did not come to the hospital, the reason was determined.
Results: The 6-month, 1-year, 2-year, 3-year, and 4-year persistence rates were 63.0%, 56.8%, 50.6%, 44.4%, and 35.8%, respectively. The most frequent reason (22.2%) for withdrawal was symptom resolution. After silodosin treatment, the international prostate symptom score and the quality of life index were significantly improved and maintained for 4 years.
Conclusions: 35.8% of previously untreated Japanese patients continued silodosin for 4 years. Many patients terminated silodosin for various reasons, the most frequent of which was symptom resolution. The effects of silodosin were maintained when the patients continued treatment.
Trial registration: This study was approved by the institutional review board of Hokkaido Prefectural Esashi Hospital (number 2007-2) and was registered in a public trial registry (UMIN000026910).

Peyronie's disease (PD) is a chronic inflammation of tunica albuginea of the corpora cavernosa that causes an inelastic plaque resulting in penis deformation. Although its etiology is not completely known, there is general consensus that PD is genetically transmitted and secondary to penile trauma. In recent years, numerous studies demonstrated the role played by oxidative stress in PD pathogenesis, and other studies have described successful use of antioxidants in PD treatment. Oxidative stress is an integral part of this disease, influencing its progression. In the early stages of PD, the inflammatory infiltrate cells produce high quantities of free radicals and proinflammatory and profibrotic cytokines, with consequent activation of transcription factor NF-κB. While conservative therapies commonly used in the early stages of PD include oral substances (Potaba, tamoxifen, colchicine, and vitamin E), intralesional treatment (verapamil, interferon, steroids, and more recently collagenase clostridium histolyticum-Xiaflex), and local physical treatment (iontophoresis, extracorporeal shock wave therapy, and penile extender), the significant results obtained by emerging treatments with the antioxidants cited in this article suggest these therapeutic agents interfere at several levels with the disease's pathogenetic mechanisms. Antioxidants therapy outcomes are interesting for good clinical practice and also confirm the fundamental role played by oxidative stress in PD.

Objective: The aim of this study is to evaluate the response to low-intensity extracorporeal shock wave therapy in a group of patients with organic vascular erectile dysfunction.
Materials and methods: This is an observational retrospective study. The researchers reviewed 710 patients with a clinical diagnosis of organic vascular erectile dysfunction (ED) of more than 3-month duration from male sexual health clinics of the Boston Medical Group from 12 cities in Spain and 4 in Mexico. Patients received 5 outpatient shock wave therapy sessions. They were evaluated with the erection hardness score (EHS) before the first session (n = 710), at the end of the last session (n = 710), and one month after the last session (n = 412).
Results: In the first examination, the EHS improved in 43.1% (306/710) of subjects compared to the baseline measurement and ability to penetrate increased from 26.8% to 44% (p < 0.0001). In the second examination, the ability to penetrate was 37.9%, lower than in the first (p=0.042) but higher than the baseline (p=0.0001).
Conclusions: The results suggest that the shock wave therapy with or without concomitant treatments improved the quality of erections in patients with erectile dysfunction treated in specialised male sexual health clinics. This trial is registered with NCT03237143.

Introduction. Concealed-buried penis is an acquired condition associated with obesity, challenging to both manage and repair. Urethral stricture is a more common disorder with multiple etiologies. Lichen sclerosus is a significant known cause of urethral stricture, implicated in up to 30%. We hypothesize that patients with buried penis have a higher rate of urethral stricture and lichen sclerosus than the general population. Methods. We retrospectively reviewed a single surgeon's (CM) case logs for patients presenting with a buried penis. All patients were evaluated for urethral stricture with cystoscopy or retrograde urethrogram either prior to or at the time of repair for buried penis. Those that had surgical repair or biopsy were reviewed for presence of lichen sclerosus. Results. 39 patients met inclusion criteria. Of these, 13 (33%) had associated stricture disease. The location of the strictures was bulbar urethra (38%), penile urethra (15%), and meatus or fossa navicularis (62%). Five patients had lichen sclerosus and urethral stricture disease, while 3 had lichen sclerosus without stricture. 11/13 stricture patients were treated. Six underwent dilation, 3 underwent meatotomy, and 2 underwent urethroplasty. No significant recurrences of stricture were seen. Conclusion. Patients with a concealed penis are more likely than the general population to have a urethral stricture and/or LS. Patients presenting with concealed penis should also be evaluated for a urethral stricture.

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 >88 cm for women and >102 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.

Objective. To determine if routine preoperative and intraoperative urine cultures (UCx) are necessary in pediatric vesicoureteral (VUR) reflux surgery by identifying their association with each other, preoperative symptoms, and surgical outcomes. Materials and Methods. A retrospective review of patients undergoing ureteral reimplant(s) for primary VUR at a tertiary academic medical center between years 2000 and 2014 was done. Preoperative UCx were defined as those within 30 days before surgery. A positive culture was defined as >50,000 colony forming units of a single organism. Results. A total of 185 patients were identified and 87/185 (47.0%) met inclusion criteria. Of those, 39/87 (45%) completed a preoperative UCx. Only 3/39 (8%) preoperative cultures returned positive, and all of those patients were preoperatively symptomatic. No preoperatively asymptomatic patients had positive preoperative cultures. Intraoperative cultures were obtained in 21/87 (24.1%) patients; all were negative. No associations were found between preoperative culture results and intraoperative cultures or between culture result and postoperative complications. Conclusions. In asymptomatic patients, no associations were found between the completion of a preoperative or intraoperative UCx and surgical outcomes, suggesting that not all patients may require preoperative screening. Children presenting with symptoms of urinary tract infection (UTI) prior to ureteral reimplantation may benefit from preoperative UCx.

Purpose: To compare the structure of the testis in fetuses with prune belly syndrome (PBS) to normal controls.
Materials and methods: We studied 6 testes obtained from 3 fetuses with PBS and 14 testes from 7 male fetuses. The testicular specimens were cut into 5-μm thick sections and stained with hematoxylin and eosin (HE), to observe the seminiferous tubules; Weigert's solution to observe elastic fibers; and picrosirius red to observe collagen. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done with the Image Pro and Image J programs. Means were statistically compared using the Mann-Whitney U test (p < 0.005).
Results: Quantitative analysis documented no differences (p = 0.4) in number of seminiferous tubules (ST) in PBS testes (mean = 8.87%, SD = 1.59), when compared to the control (mean = 11.4%, SD = 2.99) and no differences (p = 0.8) in diameter of ST in PBS testes (mean = 52.85 μm, SD = 1.58) when compared to the control group (mean = 53.17 μm, SD = 1.55), but we did observe a lower number (p = 0.0002) of Leydig cells in the PBS testes (mean = 67.03% and SD = 3.697) when compared to the control group (mean = 90.1% and SD = 2.986).
Conclusions: Our study showed a lower concentration of Leydig cells in the triad syndrome fetuses.

Aim. The aim of this study is to evaluate whether leaving the biopsy needle used during prostate needle biopsy in 10% povidone-iodine (betadine) solution affects the infectious complications forming after biopsy. Material and Method. This study retrospectively evaluated the data of 176 patients with prostate biopsy performed between December 2012 and April 2014. Patients in Group 1 (n = 89) were given ofloxacin as a prophylactic antibiotic before biopsy. Patients in Group 2 (n = 87) had the biopsy needle left in povidone-iodine solution for 1 minute before each use, in addition to antibiotic prophylaxis. The two groups were compared in terms of infective complications developing after biopsy. Results were analyzed using the Mann–Whitney U test and Fisher's exact test. Results. The distribution of infective complications after biopsy according to group was as follows. Group 1, not using betadine, had 15.7% fever, 13.5% hospital stay, 12.4% urinary retention, 10.1% prostatitis, and 5.6% sepsis. The distribution of the same complications in Group 2 using betadine was identified as 5.7% fever, 4.6% hospital stay, 3.4% urinary retention, 2.3% prostatitis, and 0% sepsis. The use of betadine was found to significantly reduce the infectious complications after biopsy compared to the control group (p < 0.05). Conclusion. At the end of this study leaving the prostate needle in povidone-iodine solution before each use during prostate biopsy was found to reduce the infective complications and hospital stay after biopsy.

Purpose. To compare the quality of health information on the Internet for keywords related to urolithiasis, to assess for difference in information quality across four main Western languages, and to compare the source of sponsorship in these websites. Methods. Health On the Net (HON) Foundation principles were utilised to determine quality information. Fifteen keywords related to urolithiasis were searched on the Google search engine. The first 150 websites were assessed against the HON principles and the source of sponsorship determined. Results. A total of 8986 websites were analysed. A proportion of HON-accredited websites for individual search terms range between 2.5% and 12.0%. The first 50 websites were more likely to be HON-positive compared to websites 51–100 and 101–150. French websites searched were more likely to be HON-positive whereas German websites were less likely to be HON-positive than English websites. There was no statistically significant difference between the rate of HON-positive English and Spanish websites. The three main website sponsors were from government/educational sources (40.2%), followed by commercial (29.9%) and physician/surgeon sources (18.6%). Conclusions. Health information on most urolithiasis websites was not validated. Nearly one-third of websites in this study have commercial sponsorship. Doctors should recognise the need for more reliable health websites for their patients.
