Review
Penile fracture is a rare condition that describes the rupture of the corpus cavernosum following direct, high-pressure trauma to the erect penis. There is no standardized management algorithm for these patients. We performed a systematic review of the past 10 years regarding management of penile fractures. A complete PRISMA-P 2015 checklist was performed where we reviewed English articles published over the past 10 years to identify 105 articles, where 63 articles were of relevance and subsequently narrowed to a total of 28 articles into the final review for this study. We determined that immediate penile exploration and tunica repair is considered the most common and current management of penile fractures with experts demonstrating that it leads to the fastest in recovery in erectile function and positive cosmetic outcomes. However, we also determined that the specific algorithm can be variable-down to the suture material, use of catheterization, urethroplasty when involved, and length of recovery/follow-up. In the last several decades, men with penile fracture have been treated, in most cases, with immediate surgical intervention. This review highlights the varying practices regarding surgical exploration, injury repair, and postoperative management in men with a penile fracture. Immediate penile exploration and tunica repair have been the mainstay approach of management.

INTRODUCTION
Erectile function (EF) outcomes after radical pelvic surgery vary widely among different studies, partly as a consequence of heterogeneity with regard to the data assessment and reporting methodology.
AIM
Review the methodology of data assessment and reporting of studies evaluating EF outcomes after radical prostatectomy (RP), radical cystectomy (RC), and rectal surgery (RS) and provide detailed recommendations to conduct future high-quality research.
METHODS
The MEDLINE database was searched for randomized clinical trials and open-label prospective or retrospective studies.
MAIN OUTCOME MEASURE
The panel reviewed the modality of data assessment and reporting concerning 3 specific areas: preoperative patients assessment, surgical technique description, and postoperative patients management and follow-up.
RESULTS
Overall, 280, 36, and 73 studies investigating EF after RP, RC, and RS, respectively, were included. Baseline EF was largely reported (88%) in studies on RP, but only 67% of the studies on either RC or RS assessed EF before surgery. Baseline comorbidities that could impact postoperative EF were reported in 62%, 64%, and 85% of studies on RP, RC, and RS, respectively. The type of surgical approach was provided in all studies, and surgical details relevant to EF (eg, nerve- or organ-sparing surgery) were reported by 86%, 81%, and 62% of studies on RP, RC, and RS, respectively. Conversely, surgeon experience was rarely reported across all studies. Validated tools were commonly used to assess postoperative EF (64% of studies for RP, 78% for RC, and 71% for RS). Only 41%, 17%, and 29% of studies on RP, RC, and RS, respectively, reported a follow-up of at least 2 years. Use of erectile dysfunction treatment after surgery was assessed by only 39%, 17%, and 4.1% of studies on RP, RC, and RS, respectively. Factors potentially influencing EF recovery (eg, urinary or fecal continence, urinary diversion) were commonly reported, but sexual desire after surgery was reported by only 18%, 42%, and 37% of studies on RP, RC, and RS, respectively.
CLINICAL IMPLICATIONS
The use of a shared methodology for the assessment and reporting of data on EF outcomes after pelvic surgery would allow better estimation of EF outcomes after pelvic surgery.
STRENGTHS & LIMITATIONS
The modality of data assessment and reporting among studies investigating EF outcome after pelvic surgery was systematically investigated to provide recommendations allowing a proper interpretation of data.
CONCLUSION
Studies on EF outcomes after radical pelvic surgery should fulfill specific criteria concerning preoperative patient assessment, reporting of surgical details, and postoperative functional outcome evaluation and management.

Several strategies to optimize penile length in the presence of Peyronie's Disease (PD) have been described so far. In case of severe curvature and preserved erectile function, plaque incision/excision (PIG/PEG) are advisable in order to maximize penile length, despite the risk of postoperative erectile dysfunction (ED), recurrent curvature, or penile shortening. For men with PD deformities associated to a certain degree of ED several lengthening techniques associated to penile prosthesis (PPI) implantation can be considered. Because of the potential postoperative complications, the indication must be balanced between patient's risk factors and surgeon's experience. Furthermore, adjuvant surgeries, such as prepubic V-Y plasty, suspensory ligament release, suprapubic lipectomy, and ventral phalloplasty, can be performed simultaneously or in a staged fashion to maximize the outcomes. Restoration a decent penile length in the case of a severe PD represents a real challenge for reconstructive surgeons. We present a systematic review of the literature on the current practices for penile lengthening in severe PD, providing the reader with a practical overview on the existing surgical strategies and their surgical and functional outcomes.

INTRODUCTION
Erectile dysfunction (ED) is a common and costly urologic condition with increasing prevalence as men age. Cost-effectiveness of ED therapies and whether cost-effectiveness varies for different populations of men remains underexplored.
AIM
To review and summarize available published data on the economic evaluation of ED therapies and to identify gaps in the literature that still need to be addressed.
METHODS
All relevant peer-reviewed publications and conference abstracts were reviewed and incorporated.
RESULTS
There are a number of medical and surgical treatment options available for ED. The economic evaluation of phosphodiesterase-5 inhibitors, particularly sildenafil, has been well described. However, minimal research has been conducted to assess the cost-effectiveness of intracavernosal injections, intraurethral suppositories, penile prosthesis surgery, vacuum erection devices, and other emerging therapies in men with different causes of ED.
CONCLUSION
Available economic evaluations of ED therapies are dated, do not reflect present-day physician, pharmaceutical, and device costs, fail to account for patient comorbidities, and may not be generalizable to today's ED patients. Substantial research is needed to evaluate the cost-effectiveness of ED treatments across different patient populations, countries, and reimbursement systems. Rezaee ME, Ward CE, Brandes ER, et al.

INTRODUCTION
Sexual function can be impaired by all prostate cancer treatment modalities, but studies specifically addressing the impact of stereotactic body radiotherapy (SBRT) on sexual function are scarce.
AIM
To systematically evaluate sexual outcomes in patients treated by SBRT for prostate cancer and determine clinical factors associated with erectile dysfunction (ED).
METHODS
A systematic review of the available literature was performed on PubMed/Medline, Scopus, and Cochrane Library databases in June 2017 according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. Only articles providing data on baseline and post-treatment sexual function after SBRT (≥5 Gy/fraction) were included in this analysis (n = 12).
MAIN OUTCOME MEASURE
Sexual function deteriorates after SBRT of the prostate.
RESULTS
Deterioration of sexual health was found, with Expanded Prostate Cancer Index Composite-26 sexual domain scores showing a median decrease of 9.2 at 12 months and a median decrease of the Sexual Health Inventory for Men subdomain score by 2.7 at 12 months (from baseline median value of 56.3 and 16, respectively). At 60 months, ED was reported by 26-55% of previously sexually functioning patients in 5 of the 12 studies.
CLINICAL IMPLICATIONS
ED affects ≤55% of previously sexually functioning patients at 5 years, as reported for other non-surgical treatment modalities.
STRENGTHS & LIMITATIONS
This study enforced strict inclusion criteria of selected studies and exclusion of patients receiving concurrent androgen deprivation therapy. However, inconsistencies in the choice of assessment tool and definition of ED hamper a robust meta-analysis of pooled data.
CONCLUSION
Sexual function decline after SBRT for prostate cancer appears to be similar to other modalities and should be specifically addressed in future studies. Loi M, Wortel RC, Francolini G, et al.

Meta-Analysis
Previous studies investigating the risk of erectile dysfunction (ED) among patients with gout have produced inconsistent evidence. Therefore, the aim of this meta-analysis was to investigate the relationship between gout and the risk of ED. The Embase, Medline, Scopus, Web of Science and Cochrane Library databases were searched for all studies assessing the risk of ED in patients with gout. Relative risks (RR) and corresponding 95% confidence intervals (CI) were adopted to estimate the association between gout and the risk of ED. Sensitivity analyses were applied to evaluate the robustness of results. Overall, 355,761 participants were included from 8 studies (3 cross-sectional and 5 cohort studies). Of these, 85,067 were patients with gout. Synthesis results showed patients with gout had a 1.2-fold higher risk of ED than individual without gout (RR 1.20, 95% CI 1.10-1.31, P < 0.001). The results of sensitivity analysis are consistent with the trend of synthesis results. The present meta-analysis revealed that the risk of ED in patients with gout was dramatically increased when compared with the general population, which suggests that clinicians should assess erectile function when treating an individual who suffers from gout.

The Journal of Sexual Medicine Jul 2019The International Index of Erectile Function (IIEF) is a patient-reported outcome measure to evaluate erectile dysfunction and other sexual problems in men.
INTRODUCTION
The International Index of Erectile Function (IIEF) is a patient-reported outcome measure to evaluate erectile dysfunction and other sexual problems in men.
AIM
To perform a systematic review of the measurement properties of the 15-item patient-reported outcome measure (IIEF-15) and the shortened 5-item version (IIEF-5).
METHODS
A systematic search of scientific literature up to April 2018 was performed. Data were extracted and analyzed according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines for structural validity, internal consistency, reliability, measurement error, hypothesis testing for construct validity, and responsiveness. Evidence of measurement properties was categorized into sufficient, insufficient, inconsistent, or indeterminate, and quality of evidence as very high, high, moderate, or low.
RESULTS
40 studies were included. The evidence for criterion validity (of the Erectile Function subscale), and responsiveness of the IIEF-15 was sufficient (high quality), but inconsistent (moderate quality) for structural validity, internal consistency, construct validity, and test-retest reliability. Evidence for structural validity, test-retest reliability, construct validity, and criterion validity of the IIEF-5 was sufficient (moderate quality) but indeterminate for internal consistency, measurement error, and responsiveness.
CLINICAL IMPLICATIONS
Lack of evidence for and evidence not supporting some of the measurement properties of the IIEF-15 and IIEF-5 shows the importance of further research on the validity of these questionnaires in clinical research and clinical practice.
STRENGTHS & LIMITATIONS
A strength of the current review is the use of predefined guidelines (COSMIN). A limitation of this review is the use of a precise rather than a sensitive search filter regarding measurement properties to identify studies to be included.
CONCLUSION
The IIEF requires more research on structural validity (IIEF-15), internal consistency (IIEF-15 and IIEF-5), construct validity (IIEF-15), measurement error (IIEF-15 and IIEF-5), and responsiveness (IIEF-5). The most pressing matter for future research is determining the unidimensionality of the IIEF-5 and the exact factor structure of the IIEF-15. Neijenhuijs KI, Holtmaat K, Aaronson NK, et al.

Meta-Analysis
PURPOSE
To systematically review and perform a meta-analysis on the safety and efficacy of endovascular therapy in the treatment of the two most common etiologies of vasculogenic erectile dysfunction (ED): veno-occlusive dysfunction (VOD) and arterial insufficiency (AI).
MATERIALS AND METHODS
PubMed, Web of Science, ScienceDirect, and Scopus databases were searched for published English literature regarding endovascular ED treatments. Case series (n ≥ 3) were included. Multiple data points were obtained, including demographic data, etiology, diagnosis method, imaging studies, treatment approach, technical success, clinical success, complications, and follow-up.
RESULTS
Sixteen relevant articles were obtained and a total of 212 patients with VOD and 162 with AI were identified. The VOD cohort were treated either percutaneously (60.4%; n = 128) or after surgical exposure of the deep dorsal vein (33.5%, n = 71), or it was unspecified (6.1%; n = 13). The most common embolic used was n-butyl cyanoacrylate (51.9%; n = 109). Meta-analysis found an overall clinical success rate of 59.8% in VOD patients. Complications occurred in 5.2% of patients (n = 11), with 9 considered to be mild and 2 considered to be severe. The AI cohort contained 162 patients most commonly treated via stenting of the internal pudendal artery (40.1%; n = 65). Meta-analysis found an overall clinical success rate of 63.2% in AI patients. Complications occurred in 4.9% of patients (n = 8), with 4 considered to be mild and 4 considered to be severe.
CONCLUSIONS
Endovascular therapy for medically refractory ED is safe and may provide a treatment alternative to more invasive surgical management; however, conclusions are limited by the heterogeneity of clinical success definitions among the included studies.

INTRODUCTION
Erectile dysfunction supplements (ED-Ss) are featured on online marketplaces like Amazon.com, with dedicated pages and claims that they naturally treat ED. However, their efficacy and safety are largely unknown, limiting the ability to counsel patients regarding their use.
AIM
To evaluate the highest rated and most frequently reviewed ED-Ss on Amazon.com to facilitate patient counseling regarding marketing myths, ingredient profiles, and evidence for product efficacy and safety.
METHODS
The Amazon marketplace was queried using the key term "erectile dysfunction" with default search settings and ranking items based on relevance. The top 6 ED-S products identified on September 29, 2018, were reviewed based on price, ratings, reviews, manufacturer, and ingredients. Consumer reviews were categorized using subtopics within the International Index of Erectile Function (IIEF) questionnaire to better understand ED-S efficacy and then reanalyzed following filtration of untrustworthy comments using ReviewMeta.com, a proprietary Amazon review analysis software.
OUTCOMES
Quantitative and qualitative evaluation of ED-S products sold on Amazon.com.
RESULTS
The top 6 ED-Ss had an average of 2,121 ± 1,282 reviews and a mean rating of 3.92 ± 0.42 stars. A total of 21 ingredients were identified in these ED-Ss. Ginseng, horny goat weed, L-arginine, and tongkat ali were the most popular ingredients included in the analyzed products. Our literature review identified 413 studies involving the 21 identified ingredients, of which 59 (16%) involved human subjects. Among these 69 human studies, only 12 (17%) investigated supplement ingredients individually and reported improvement in ED. Analysis of top-ranked customer reviews from the first 2 pages of reviews for each supplement revealed differences in IIEF scores before and after ReviewMeta.com filtration. After filtration, we observed a 77% decrease in reviews reporting improved erection strength, an 83% decrease in reviews reporting improved ability to maintain erection, a 90% decrease in reviews reporting increased sexual satisfaction, an 88% decrease in reviews reporting increased enjoyment with intercourse, and an 89% decrease in reviews reporting increased erection confidence.
STRENGTHS & LIMITATIONS
Study strengths include a novel approach to ascertaining consumers' perceptions and satisfaction with ED-Ss and practical summary information that clinicians can provide to patients. Limitations include selection bias, the small number of supplements analyzed, and the proprietary nature of the Amazon review analysis software.
CONCLUSIONS
Our investigation revealed that human studies evaluating the efficacy of ED-S ingredients are limited and have yielded no definitive findings of the effects on ED. Patients considering ED-S use should receive appropriate counseling, given the prevalence of disingenuous reviews and the ready availability of Food and Drug Administration-approved drug therapies.

BACKGROUND
Penile prostheses are commonly used to achieve erectile rigidity after phalloplasty in trans masculine patients. Implantation poses significant challenges because of the delicate nature of the neophallus and lack of native erectile tissue. Many groups have developed novel phalloplasty and prosthesis insertion techniques, but none have proven superior.
AIM
To analyze and aggregate reported characteristics and outcomes of penile prosthesis implantation in the trans masculine patient.
METHODS
A comprehensive literature search of Medline, EMBASE, and Cochrane Registry databases was conducted for studies published through February 19, 2019, with multiple search terms related to penile prosthesis use in gender-affirming surgical procedures.
OUTCOMES
Studies were included and tabulated if they reported prosthesis outcomes in patients who received a neophallus as part of a gender-affirming procedure.
RESULTS
23 journal articles met inclusion criteria from 434 references identified. All selected articles were either retrospective or case series/reports. A total of 1,056 patients underwent phalloplasty, and 792 received a penile prosthesis. Most (83.6%) of the prostheses were inflatable, whereas 16.4% were non-inflatable. The number of cylinders used for each prosthesis was 61.0% single-cylinder and 39.0% double-cylinder. The mean follow-up duration was 3.0 years. Of patients who received a prosthesis, 36.2% reported a prosthesis complication; at follow-up 60.0% of patients had their original implant present, and 83.9% reported achieving penetration.
CLINICAL IMPLICATIONS
Prosthesis implantation in gender-affirming operations poses significant risk of complication, but it is still a reasonable and useful method to achieve rigidity necessary for sexual intercourse.
STRENGTH & LIMITATION
This is the first study to aggregate all reported penile prosthesis characteristics and outcomes in trans masculine patients. This study was significantly limited by inconsistent reporting of demographics, sensation, urinary health, patient satisfaction, and penetrative sex. The lack of comparative studies precluded any meaningful meta-analytical comparison.
CONCLUSIONS
There is a great need for a prosthesis designed to meet the specific needs of the trans masculine patient after phalloplasty. Standardized methods of reporting implant outcomes including sexual function, sensation, and patient satisfaction should be refined for future studies. This study can assist patients and surgeons about the risks and benefits of this procedure. Rooker SA, Vyas KS, DiFilippo EC, et al.
