Context: Extracorporeal shock wave lithotripsy (ESWL) has inferior results in the lower calyceal stones, especially in obese patients. Aims: This study aimed at evaluating of the efficacy of extracorporeal shockwave lithotripsy, with modified position of the machine head in the treatment of single lower calyceal stones in obese patients. Settings and Design: This was a prospective study (phase IV trial). Subjects and Methods: We studied the anterior rotation of the shock wave machine head in obese patients for the treatment of lower calyx stones. From February 2015 to June 2019, 105 obese patients (body mass index [BMI] ≥35) having lower calyx stones (≤20 mm) underwent ESWL at our institute. The procedure was done in a supine position, and the head of the shock-wave machine was tilted anteriorly. ESWL was considered successful if the kidney was completely cleared of stones. Statistical Analysis Used: The statistical methods used were descriptive statistics, mean, standard deviation frequency analysis, Chi-square test, unpaired t-test test, and Pearson correlations (r). Results: The mean BMI of these patients was 39.71 ± 2.8 kg/m2, the mean stone size was 17.4 ± 2.1 mm, the mean stone density was 767.1 ± 193.4 Hounsfield unit, and the mean of skin to stone distance (SSD) was 145.4 ± 4.5 mm. ESWL was successful in 86 (81.9%) patients; 13 patients (12.4%) showed complete success after the first session, while 37 (35.2%), 25 (23.8%), and 11 (10.5%) patients showed success after the second, third, and fourth sessions, respectively. ESWL failed in 19 (19.1%) cases. The success rate decreased significantly with higher stone density and SSD (P < 0.001), with negative correlations (r values) of −0.871 and −0.811, respectively. Conclusions: Anterior rotation of the head of the shock wave machine is a suitable option for the treatment of lower calyceal stones in obese patients.

Objective: The aim of this study was to evaluate the Penile Perception Score (PPS) after repair of distal penile hypospadias using tabularized incised plate (TIP) and Mathieu procedures. Methods: A randomized controlled study was conducted at urology department from October 2013 to May 2014. It included 60 children who were divided into three groups: group A included 20 patients with distal hypospadias corrected using TIP; group B included 20 patients with distal hypospadias corrected using Mathieu; and group C included 20 children with normal male genitalia who were circumcised and considered as a control group. Results: There were no statistically significant differences between group A and group B in urologists’ and parents’ average sum of PPS evaluation, but urologists’ satisfaction was more than parents’ satisfaction. The PPS for TIP was 8.43 and 7.80 for urologists and parents, respectively. The difference was significant. The PPS for Mathieu were 8.04 and 7.89 for urologists and parents, respectively, with no significance. There were no statistically significant differences between group A and group B in the postoperative evaluation by urologists and by parents in meatus, glans, shaft skin, and general appearance. There were complications in 10% of cases from group A in the form of fistula, in 30% of cases from group B in the form of fistula in 25% and meatal stenosis in 5%, and no complication in group C. Conclusion: TIP showed better PPS score compared with Mathieu in hypospadias repair. However, the results of this study were not statistically significant. PPS was a good scale to evaluate hypospadias repair after surgery. Keywords: hypospadias, parents and urology, Penile Perception Score

Summary Background Using the Snodgraft technique in patients with urethral plate less than 8 mm to repair distal hypospadias is still debatable. Some authors assume that augmentation may be beneficial. We aimed to compare the outcomes of the Snodgrass vs Snodgraft procedure in patients with a narrow urethral plate less than 8 mm. Methodology This prospective randomized study included 60 children who had been treated by the Snodgrass or Snodgraft procedure for repair of distal penile hypospadias with narrow urethral plate from March 2017 to September 2018. They were randomized into two subgroups. Group 1 (30 patients) underwent tubularized incised plate urethroplasty, whereas the second group (30 patients) underwent the Snodgraft procedure by using the inner prepuce. Operative details, postoperative period, and complications were reported and statistically analyzed using IBM SPSS software package version 20.0. Results The operative time was longer for patients who underwent the Snodgraft procedure: 78 (55–95) and 110 (80–140) minutes in groups 1 and 2, respectively. In group 1, there was one case of meatal stenosis which was resolved by urethral dilation using the local anesthetic cream in the outpatient clinic. In addition, there was another case of distal penile fistula. In group 2, there was a case of complete wound disruption and another of distal penile fistula. There was no significant difference in the complication rate in any group. Conclusion The operative time was longer in group 2 than in group 1 but with comparable outcomes. The Snodgraft procedure is not superior to the Snodgrass operation in the narrow healthy urethral plate. Table . Operative and postoperative follow-up data in both groups.

Objective To evaluate the outcome of an intraprostatic injection of botulinum toxin-A (BTX-A) in men with refractory chronic prostatitis-associated chronic pelvic-pain syndrome (CP/CPPS) and to compare the efficacy of the transurethral and transrectal routes. Patients and methods In an uncontrolled randomised clinical trial conducted in men with refractory CP/CPPS, the patients were classified into two groups according to the route of BTX-A injection; transurethral (group 1, 28 patients) and transrectal ultrasonography-guided (group 2, 35 patients). The chronic prostatitis symptom index (CPSI), maximum urinary flow rate (Qmax) and white blood cell (WBC) count in expressed prostatic secretion (EPS) were measured before and at 3, 6 and 12 months after the injection. A significant clinical improvement (SCI, defined as a reduction of 4 points or a 25% decrease in total CPSI score) was correlated with patient age, prostate volume and symptom duration. Results In group 1, the pain and quality-of-life domain scores improved, but statistically significantly only at 6 months. The voiding score improved at all follow-up visits. In group 2 there was a significant improvement in all the CPSI domain scores at all follow-up visits, except for pain, which was insignificantly improved by 12 months. The SCI ratings in groups 1 and 2 were 36%, 79% and 57%, and 49%, 89% and 74% in group 2 at the three follow-up visits, respectively. The Qmax was significantly improved in both groups during the follow-up (except at 12 months in group 1). There was a significant reduction in the mean WBC count in the EPS in patients with inflammatory prostatitis. Both prostate volume and symptom duration were significantly associated with a lower SCI rating. Conclusion BTX-A is an available treatment option for patients with refractory CP/CPPS. It is more effective in patients with a small prostate and short symptom duration. The transrectal route provided better results than the transurethral route. More prospective longer term studies are needed.

Objectives To compare the clinical efficacy of the on-demand use of four drugs in the management of patients with premature ejaculation (PE), as the off-label use of selective serotonin-reuptake inhibitors and topical penile anaesthetics is frequently indicated for the management of patients with PE, and tramadol HCl and sildenafil citrate were also tried for managing this disorder, but with recommendations based on weak evidence. Patients and methods This was a single-centre, single-blind, placebo-controlled clinical trial conducted on 150 patients who had PE for >1 year. Patients were randomised equally into five groups. On-demand tramadol, sildenafil, paroxetine, local lidocaine gel or placebo was given for patients in groups 1–5, respectively. During the month before treatment, the intravaginal ejaculation latency time (IELT) and sexual satisfaction scores (on a 0–5-point scale) were measured and compared to the mean IELT and sexual satisfaction scores recorded during 4 weeks of on-demand drug administration, with monitoring of any possible side-effects. Results Tramadol-treated patients had a significantly longer mean (SD) IELT, of 351 (119) s, than the other groups. Local anaesthetic was significantly better than paroxetine in prolonging the IELT, at 278 (111) vs. 186 (65) s, respectively. The improvement in sexual satisfaction was significantly better in the sildenafil group, with a mean (SD) improvement of 2.9 (1) points, than in the paroxetine and local anaesthetic groups, at 2.2 (0.9) and 1.9 (0.9) points, respectively. Conclusions The four drugs significantly improved IELT values over placebo. Tramadol was associated with significantly longer IELT values, whilst sildenafil induced significantly better sexual satisfaction than the other drugs. The four drugs had tolerable side-effects.
