Scrotoplasty at Time of Penile Implant is at High Risk for Dehiscence in Diabetics.

INTRODUCTION: Scrotoplasty has become a common practice during insertion of penile prosthesis, improving patient perception of penile length. Previous reports on scrotoplasty outcomes have only focused on the perceived benefits. The risk of wound complications after scrotoplasty is unknown. AIM: Identify wound complications and associated risk factors of scrotoplasty with insertion of penile prosthesis. METHODS: A retrospective review of a single-surgeon series (T.S.K.) of patients who underwent scrotoplasty with initial insertion of inflatable penile prosthesis (IPP) was performed from 2009-2014. Surgical outcomes and wound complications after scrotoplasty were examined, along with patient information, including basic demographics, medical comorbidities, and perioperative data. MAIN OUTCOME MEASURES: Studied outcomes included rate of wound complications after scrotoplasty and IPP insertion and identification of risk factors for wound dehiscence. RESULTS: Of the 103 scrotoplasties performed during the study period, a total of 15 had mild, moderate, or major wound dehiscence. Of these 15 cases, 9 had mild dehiscence and 5 cases had moderate dehiscence and required stitches to be placed in clinic to reinforce the closure. 1 patient had a major dehiscence requiring a return to the operating room for a washout, with exchange of IPP to malleable prosthesis. Multiple risk factors for wound dehiscence were found, including diabetes (odds ratio 6.1, CI 1.5, 25.0, P = .0129) and scrotoplasty technique (odds ratio 4.9, CI 1.2, 8.6, P = .003). Other examined variables, including patient age, Peyronie's disease, hypertension, intraoperative penile modeling, smoking, and device manufacturer, were not associated with wound dehiscence. CLINICAL IMPLICATIONS: Patients with diabetes and scrotoplasties performed via V-Y plasty are more likely to experience wound dehiscence. STRENGTHS & LIMITATIONS: Strengths include a single surgeon, thus lending continuity of skill and technique, a consecutive series, and 100% short-term follow-up. Limitations include retrospective design, single institution series, and lack of long-term follow-up. CONCLUSION: Although scrotoplasty can improve patient satisfaction with IPP, scrotoplasty can lead to increased patient morbidity. Diabetic patients are at increased risk for wound complication after scrotoplasty. Gupta NK, Sulaver R, Welliver C, et al.

Manufacturers' data show increasing implanted cylinder sizes and measured corporal lengths in inflatable penile implants.

INTRODUCTION: We sought to determine whether measured corporal length (MCL) or implanted device size (IDS) has changed. METHODS: Data were obtained from the two major penile implant companies from the years of 2005-2010 and analyzed. While we requested similar data, companies supplied information at their discretion with MCL provided by American Medical Systems and IDS provided by Coloplast. Intra-patient corporal discrepancies, disease state effects, rear tip extenders (RTEs) use and place of implantation were also provided in some part by companies. RESULTS: MCL and IDS increased during the study period. Despite the general trend of MCL/IDS, clinically significant (0.5 cm or greater) decreases in MCLs were noted in patients with Peyronie's disease (PD) or a history of radical pelvic surgery (excludes prostatectomy). In only 2.7 % of cases was there an intra-patient discrepancy in cylinder size (>1 cm). IDS was longer in the USA (US, 19.4 cm) compared to outside the US (OUS, 17.7 cm, p < 0.0001). Cylinders were implanted without RTEs in 48.3 % of US cases and 73.7 % of OUS cases (p < 0.0001). In Coloplast devices there was an overall statistically significant change in the use of 16 cm (less utilized) and 20 and 22 cm (more utilized) cylinder lengths during the study period in US implants. CONCLUSION: MCL and IDS increased during the study period. Men with a history of PD or radical pelvic surgery are at highest risk to have shorter MCL and to possibly receive shorter implants. Intra-patient IDS inconsistency is rare and should prompt investigation.

Clinically and Statistically Significant Changes Seen in Sham Surgery Arms of Randomized, Controlled Benign Prostatic Hyperplasia Surgery Trials.

PURPOSE: Medication trials frequently involve a placebo arm to more fairly assess the efficacy of the study drug. However, benign prostatic hyperplasia surgery trials rarely include a sham surgery group due to the inherent risks associated with simulating treatment in these patients. As a result the placebo response to sham surgery for benign prostatic hyperplasia is largely unknown. MATERIALS AND METHODS: We systematically reviewed the available literature to look for randomized, controlled trials involving endoscopic or intraprostatic injection benign prostatic hyperplasia treatments that included a sham surgical arm from January 1990 to February 2015. Studies that included an objective symptom questionnaire and maximum urinary flow at 3 months were included. Results were analyzed together with weighting based on study sample size. RESULTS: The initial search yielded a total of 1,998 potential studies. After reviewing abstracts and full text articles 14 randomized, controlled trials were included in some part. An average decrease from 22.3 to 16.7 (-27%) was seen in studies of the AUASS (American Urological Association symptom score) 3 months after a sham endoscopic procedure (p=0.0003) with an increase in maximum urinary flow of 1.3 ml per second (14%, p=0.001) at 3 months. Prostate injection based studies at 3 months were similar with a decrease from 21.3 to 15.7 (-26%, p<0.001). Maximum urinary flow increased by 2.0 ml per second (23%, p=0.043). CONCLUSIONS: Sham controlled endoscopic and injection benign prostatic hyperplasia interventions demonstrate a considerable and statistically significant change in symptom scores and maximum urinary flow, which is comparable to the response seen in medication trials. Future uncontrolled benign prostatic hyperplasia surgical trials should consider these findings when interpreting outcomes.

Urethral mobilization for distal and mid shaft hypospadias with chordee.

PURPOSE: Many options are available for repairing mid shaft to distal hypospadias. Reported complications include poor cosmesis, persistent chordee, meatal stenosis and fistula. We hypothesized that advancing the intact native urethra would facilitate chordee correction and minimize complications. MATERIALS AND METHODS: We retrospectively reviewed our records of all 248 hypospadias repairs done from July 2003 to May 2009 and identified patients younger than 18 years with distal or mid shaft hypospadias who underwent repair by urethral mobilization. The outcomes recorded were patient satisfaction, bladder scan volume, and the rate of fistula, meatal stenosis or other complications. RESULTS: Of the patients 83 met study inclusion criteria, including 5 (6%) treated with previous failed hypospadias operations. The hypospadias site was the distal, mid shaft and megameatal intact prepuce variant in 69 (83.1%), 11 (13.3%) and 3 patients (3.6%), respectively. Chordee was present in 80 patients (96.4%). The mean degree of chordee was 61.5 degrees, mean age at operation was 35.7 months and mean followup was 18 months (range 0.25 to 79). Of parental responses 94% were pleased or very pleased. Mean bladder volume on bladder scan was 9.7 ml (range 0 to 81). Fistula developed in 1 patient (1.2%). There were no meatal stenosis cases. CONCLUSIONS: Urethral mobilization results in excellent cosmesis and a low complication rate. This technique is especially well suited to patients with prior operations or deficient preputial skin. Using the native urethra with its blood supply is our preferred method of repairing distal and mid shaft hypospadias with chordee.
