PURPOSEnTestosterone replacement therapy in men with prostate cancer is controversial, with concern that testosterone can stimulate cancer growth. We evaluated the safety and efficacy of testosterone in hypogonadal men with prostate cancer treated with radical prostatectomy.nnnMATERIALS AND METHODSnWe performed a review of 103 hypogonadal men with prostate cancer treated with testosterone after prostatectomy (treatment group) and 49 nonhypogonadal men with cancer treated with prostatectomy (reference group). There were 77 men with low/intermediate (nonhigh) risk cancer and 26 with high risk cancer included in the analysis. All men were treated with transdermal testosterone, and serum hormone, hemoglobin, hematocrit and prostate specific antigen were evaluated for more than 36 months.nnnRESULTSnMedian (IQR) patient age in the treatment group was 61.0 years (55.0-67.0), and initial laboratory results included testosterone 261.0 ng/dl (213.0-302.0), prostate specific antigen 0.004 ng/ml (0.002-0.007), hemoglobin 14.7 gm/dl (13.3-15.5) and hematocrit 45.2% (40.4-46.1). Median followup was 27.5 months, at which time a significant increase in testosterone was observed in the treatment group. A significant increase in prostate specific antigen was observed in the high risk and nonhigh risk treatment groups with no increase in the reference group. Overall 4 and 8 cases of cancer recurrence were observed in treatment and reference groups, respectively.nnnCONCLUSIONSnThus, testosterone therapy is effective and, while followed by an increase in prostate specific antigen, does not appear to increase cancer recurrence rates, even in men with high risk prostate cancer. However, given the retrospective nature of this and prior studies, testosterone therapy in men with history of prostate cancer should be performed with a vigorous surveillance protocol.

A lack of consensus and few data support testosterone replacement therapy (TRT) in hypogonadal men who have been treated for prostate cancer (CaP), particularly those who have received radiation therapy. We performed retrospective review of 13 hypogonadal men with CaP, treated with brachytherapy or external beam radiotherapy who were subsequently treated with testosterone (T) between 2006 and 2011. Serum T, free T (FT), estrogen (E), sex hormone-binding globulin (SHBG), prostate-specific antigen (PSA), hemoglobin (Hgb) and hematocrit (Hct) values were evaluated approximately every 3 months after TRT initiation up to 67 months of follow-up. Prostate biopsies demonstrated four men with Gleason (Gl) 6, 7 with Gl 7 and 2 with Gl 8 disease. Median (interquartile range) age at TRT initiation was 68.0 (62.0–77.0) years, initial T 178.0 (88.0–263.5)u2009ngu2009dl−1, FT 10.1 (5.7–15.0)u2009pgu2009ml−1 and PSA 0.30 (0.06–0.95)u2009ngu2009ml−1. Median follow-up after TRT initiation was 29.7 months (range 2.3–67.3 months). At median follow-up, a significant increase in mean T (368.0 (281.3–591.0)u2009ngu2009dl−1, P=0.012) and SHBG were observed, with no significant increases in Hgb, Hct, E, FT, or PSA (0.66 (0.16–1.35)u2009ngu2009ml−1, P=0.345). No significant increases in PSA or CaP recurrences were observed at any follow-up interval. TRT in the setting of CaP after treatment with radiation therapy results in a rise in serum T levels and improvement in hypogonadal symptoms without evidence of CaP recurrence or progression.

Purpose Autologous platelet rich plasma (PRP) is used increasingly in a variety of settings. PRP injections have been used for decades to improve angiogenesis and wound healing. They have also been offered commercially in urology with little to no data on safety or efficacy. PRP could theoretically improve multiple urologic conditions, such as erectile dysfunction (ED), Peyronies disease (PD), and stress urinary incontinence (SUI). A concern with PRP, however, is early washout, a situation potentially avoided by conversion to platelet rich fibrin matrix (PRFM). Before clinical trials can be performed, safety analysis is desirable. We reviewed an initial series of patients receiving PRFM for urologic pathology to assess safety and feasibility. Materials and Methods Data were reviewed for patients treated with PRFM at our center from November 2012 to July 2017. Patients were observed immediately post-injection and at follow-up for complications and tolerability. Where applicable, International Index of Erectile Function (IIEF-5) scores were reviewed before and after injections for ED and/or PD. Pad use data was collected pre/post injection for SUI. Results Seventeen patients were identified, with a mean receipt of 2.1 injections per patient. Post-procedural minor adverse events were seen in 3 men, consisting of mild pain at injection site and mild penile bruising. No patients experienced complications at follow-up. No decline was observed in men completing pre/post IIEF-5 evaluations. Conclusions PRFM appears to be a safe and feasible treatment modality in patients with urologic disease. Further placebo-controlled trials are warranted.

Urethrocavernous fistula is rarely reported, though should be considered within the differential diagnosis for men who present with urethral bleeding, particularly at time of erection. Ultrasonography with concomitant intracavernosal injection can be considered to confirm the diagnosis. Here we report a case of urethrocavernous fistula in a 48 year old man without preceding traumatic event.

Background: Reconstruction for complex urethral strictures may necessitate grafting. Buccal mucosal graft (BMG) harvest involves additional morbidity, making ‘off-the-shelf’ options attractive. Multiple extracellular matrices (ECMs) have been used with varying degrees of success. We reviewed our experience with MatriStem (ACell, Inc., Columbia, MD, USA) to assess safety and clinical/histologic outcomes. Methods: All patients undergoing acellular matrix-based reconstruction were included. Data regarding indications for surgery, patient demographics, subsequent procedures, clinical outcomes, and histologic analysis, when present, were collected. Results: Eight patients undergoing urethral reconstruction with ECM were identified. All repairs were performed as staged procedures. Grafting was performed with either MatriStem alone or MatriStem and concomitant BMG. Seven patients (88%) underwent prior endoscopic intervention and five patients (71%) had failed to respond to one or multiple prior urethroplasties. Length of involved segments ranged from 2.5 to 15 cm. ECM graft placement was feasible and demonstrated excellent graft take. Among patients undergoing second-stage repairs (four of eight, 50%), 50% remained patent without the need for subsequent dilation. Conclusions: Use of acellular matrix grafts in urethral reconstruction appears safe and feasible. Acellular matrix performs similarly to BMG with respect to graft take and contraction following staged repair. Further study is warranted.

BACKGROUNDnProximal corporal perforation at time of dilation, although rare, may occur due to factors related to patient anatomy, presence of intra-cavernosal fibrosis, and/or surgical technique.nnnAIMnTo describe tools and techniques designed to prevent and identify proximal corporal perforation, and maneuvers to minimize the risk of subsequent cylinder migration once proximal perforation has been recognized, such that the operation may proceed and result in an acceptable outcome.nnnMETHODSnWe discuss tips for prevention, recognition, and management of proximal corporal perforation by presenting a review of the literature as well as our preferences based on a high-volume experience with penile prosthesis surgery.nnnOUTCOMESnDescribed techniques aim to minimize risk of cylinder migration in the absence of true proximal repair.nnnRESULTSnAlthough proximal perforation may be obvious at times, particularly with a sudden loss of resistance during dilation, discrepant corporal measurements and/or dissimilar proximal deflection of the dilator should also increase the index of suspicion. Numerous techniques have been employed to theoretically reduce the risk of cylinder migration in the setting of proximal corporal perforation. These include formal corporal repair (historical), windsock repairs with non-absorbable grafts, absorbable plugs, and suture fixation of the rear tip extender or shod material covering implant tubing.nnnCLINICAL TRANSLATIONnIntra-operative recognition of proximal corporal perforation, coupled with understanding of surgical strategies to minimize the risk of future device migration, may allow completion of an operation that still results in an optimal outcome.nnnCONCLUSIONSnTechniques described to prevent proximal migration are not strongly evidence-based, but rooted in logic and supported by high-volume implanters. Intra-operative perforation of the proximal corpora, although rare, can threaten the success of penile implant surgery, though the techniques described herein have been developed to mitigate the potential for subsequent device migration, allowing surgery to proceed and to achieve the desired clinical result.

Purpose Rate of continence after artificial urinary sphincter (AUS) placement appears to decline with time. After appropriate workup to exclude inadvertent device deactivation, development of urge or overflow incontinence, and fluid loss, many assume recurrent stress urinary incontinence (rSUI) to be secondary to nonmechanical failure, asserting urethral atrophy as the etiology. We aimed to characterize the extent of circumferential urethral recovery following capsulotomy and that of pressure regulating balloon (PRB) material fatigue in men undergoing AUS revision for rSUI. Materials and Methods Retrospective review of a single surgeon database was performed. Cases of AUS removal/replacement for rSUI involving ventral subcuff capsulotomy and intraoperative PRB pressure profile assessments were identified. Results The described operative approach involving capsulotomy was applied in 7 patients from November 2015 to September 2017. Mean patient age was 75 years. Mean time between AUS placement and revision was 103 months. Urethral circumference increased in all patients after capsulotomy (mean increase 1.1 cm; range 0.5–2.5 cm). Cuff size increased, remained the same, and decreased in 2, 3, and 2 patients, respectively. Six of 7 patients underwent PRB interrogation. Four of these 6 PRBs (66.7%) demonstrated pressures in a category below the reported range of the original manufacturer rating. Conclusions Despite visual appearance to suggest urethral atrophy, subcuff capsulotomy results in increased urethral circumference in all patients. Furthermore, intraoperative PRB profiling demonstrates material fatigue. Future multicenter efforts are warranted to determine if capsulotomy, with or without PRB replacement, may simplify surgical management of rSUI with reductions in cost and/or morbidity.

Purpose Primary care providers harbor misconceptions regarding penile prosthetic surgery, largely overestimating the rate of infection. Rates of infection following surgery for primary placement and revision are estimated as 1% to 3% and 10% to 18%, respectively. Our objective was to determine the contemporary incidence of infection following inflatable penile prostheses surgery at an academic training center where surgeons-in-training are routinely involved. Materials and Methods Review of a prospectively collected single-surgeon database was performed. All cases of inflatable penile prostheses placement from January 2011 through June 2017 were reviewed. Information regarding training level of assistant surgeon(s) was collected, and follow-up data was compiled regarding postoperative infections and need for revision surgery. Results Three hundred nine cases meeting inclusion criteria were identified. Mean patient age was 64.2 years, and mean follow-up was 28.7 months. Distribution involved 257 (83.2%) for primary placement, 45 (14.6%) for removal/replacement, and 7 (2.3%) in setting of prior device removal. Diabetes was noted in 31.1% of men. Surgeon-in-training involvement was noted in 100% of cases. Infection was confirmed in a patient who had skin breakdown over an area of corporal reconstruction with polytetrafluoroethylene. The overall postoperative infection rate was 0.3%. Conclusions In this series from an academic training center, infection following penile prosthetic surgery is low, similar to other centers of excellence, even with 100% involvement of surgeons-in-training. This data should be used to better inform primary care providers and members of the general public potentially interested in restoration of sexual function.

The lower urinary tract consists of interrelated structures including the bladder, urethra, smooth, and striated sphincters, pelvic floor muscles, and the prostate gland in men with a common function of providing effective urinary storage and voluntary urinary expulsion. These functions are achieved in two discrete phases of micturition [1].
