AbstractPeyronie’s disease is a common yet poorly understood condition characterized by penile pain, curvature, sexual dysfunction and psychological bother. Peyronie’s disease represents a penile wound healing disorder, and is thought to arise from exuberant scarring in response to penile trauma in genetically predisposed men. In the absence of active treatment, the majority of men experience stable or worsening symptoms, with few reporting spontaneous resolution in penile curvature or other deformity. In contrast, penile pain improves or resolves in the majority of men. Treatment options vary based on symptom severity and stability. Several oral therapies are commonly prescribed, although to date there are no strong data to support any oral agents as monotherapy for Peyronie’s disease. Other options including penile traction therapy and intralesional injections result in modest improvements for many patients, particularly when used early after symptom onset. Penile straightening through approaches, such as penile plication and plaque incision or partial excision and grafting, represent the most rapid and reliable approach to correct penile curvature once the symptoms have stabilized. Side‐effects vary based on the type of surgery carried out, and include penile shortening, sensation changes and erectile dysfunction in the minority of men. In patients with drug refractory erectile dysfunction and Peyronie’s disease, placement of a penile prosthesis will address both issues, and is associated with high levels of patient satisfaction. The current review provides a practical approach to the modern evaluation and management of patients presenting with Peyronie’s disease.

Abstract Background Climacturia is an under-reported complication of definitive therapy for prostate cancer (PCa) - that is, radical prostatectomy (RP) and/or radiation therapy (RT). Aim We sought to identify the prevalence and predictors of climacturia and associated patient/partner bother in patients with and without prior PCa treatment. Methods We analyzed a database of patients who presented to our Men's Health clinic and filled out a questionnaire related to sexual function and pertinent medical histories. The prevalence of climacturia and associated patient/partner bother in patients with/without prior RP/RT was calculated. Univariable and multivariable logistic regressions were performed to identify predictors associated with climacturia and patient/partner bother. Outcomes The primary outcomes were the prevalence and predictors of climacturia and associated patient/partner bother in patients with/without history of definitive PCa treatment. Results Among 1,117 patients able to achieve orgasm, 192 patients (17%) had prior history of definitive therapy for PCa (RP alone = 139 [72%]; RT alone = 22 [11%]; RP + RT = 31 [16%]). Climacturia was reported by 39%, 14%, 52%, and 2.4% of patients with history of RP alone, RT alone, RP + RT, and neither RP nor RT, respectively (P < .05 between all groups). 33 to 45 percent of patients with climacturia noted significant patient/partner bother. Factors significantly associated with climacturia were prior RP, prior RT, history of other prostate surgery, and erectile dysfunction, although erectile dysfunction was not significant on multivariable analysis. Significant reduction in climacturia prevalence was noted for patients who were ≥1 year out from RP, compared with patients who were <1 year out. Among patients with prior RP/RT, stress urinary incontinence was associated with increased risk of climacturia, whereas diabetes was associated with decreased risk. No factors were associated with patient/partner bother. Among patients with prior RP, nerve-sparing technique did not predict presence of climacturia but was associated with reduced patient/partner bother. Clinical translation Given significant prevalence of climacturia and associated patient/partner bother, patients should be counseled on the risk of climacturia before undergoing RP/RT. Strengths and limitations Strengths include the large study population and the focus on both RP and RT. Limitations include the facts that this is a single-institution study that primarily relies on patients’ subjective reporting and that the study population may not represent the general population. Conclusions Climacturia affects a significant proportion of patients with history of RP/RT for PCa, and many patients and their partners find this bothersome.

Abstract Background A subset of patients with Peyronie's disease (PD) treated with collagenase clostridium histolyticum (CCH) experience persistent bother and some require surgery. Aim We characterize patients experiencing persistent bother after CCH treatment and identify associations and predictors of surgical intervention/outcomes. Methods We retrospectively identified patients with PD from October 2014 to October 2019 and identified those presenting with persistent bother after CCH treatment by other urologists. Intracavernosal injection and penile Doppler ultrasonography were performed, and subsequent interventions/outcomes were recorded. Baseline characteristics were compared with Student t-test and chi-square test. Predictors of surgical intervention and complications were assessed using multivariable logistic regression. Outcomes The primary outcome was surgery after CCH treatment. Secondary outcomes included worsened erectile function, sensory deficits, and penile length change. Results Of 573, 67 (11.7%) patients with PD had undergone prior CCH treatment with median 6 injections (range 2–24). Mean post-CCH PD Questionnaire bother score was 10.1 (SD: 3.1), and total International Index of Erectile Function-5 was 15.3 (SD: 8.7). Mean PD duration was 27.8 (SD: 35.7) months, with a mean composite curvature (MCC) of 69.0° (SD: 33.8) measured after injection. Of 67, 44 (65.7%) patients had MCC >60°. Of 67, 52 (77.6%) patients had indent, narrowing, or hourglass and 26 (38.8%) had hinge effect (buckling of the erect penis with axial pressure) on examination. Calcification was identified in 26 of 67 (38.8%) patients, with grade 3 calcifications comprising 6 of 23 (26.1%) patients. Of 67, 33 (49.3%) patients underwent surgery, with 20 (60.1%) undergoing partial plaque excision and grafting with/without tunica albuginea plication, 6 (18.2%) undergoing tunica albuginea plication alone, and 7 (21.2%) undergoing penile prosthesis with plaque incision and grafting. Surgical patients had greater mean curvature (82.6 vs 55.4, P = .001) and were more likely to have hinge (54.5% vs 20.6%, P = .005). On multivariable analysis, MCC ≥60° predicted patient’s decision for surgery (odds ratio: 2.99, P < .01, 95% confidence interval: 1.62–4.35). There were no associations between surgical complications and number of injections or CCH-associated adverse events. Clinical Implications Patients presenting with persistent bother after CCH treatment often have narrowing and calcifications (despite calcifications being a contraindication to CCH treatment), and those who have hinge or severe curvature are more likely to undergo surgery with low rates of complications. Strengths/Limitations This study's generalizability is limited by selection bias, but useful data are provided for patient counseling. Conclusion Patients with persistent bother after CCH treatment had high rates of indentation/narrowing, plaque calcifications, and MCC >60° at completion of CCH treatment. Surgical intervention is more common with hinge and is safe and feasible in these patients, with low rates of complications. These findings suggest possible negative prognostic factors for CCH treatment, which merit further investigation.

AbstractIntroductionPeyronie's disease (PD) is characterized by pain, deformity, sexual dysfunction, and psychological bother. Several treatments are available with varying levels of efficacy, and significant limitations exist with the currently available literature.AimTo explore modern-era methodological challenges inherent to PD research as they pertain to intervention studies.MethodsWe performed a critical review of the PD intervention literature to identify common methodological challenges with emphasis on aspects of patient assessment and treatment outcomes, study design, and statistical analysis. The key objective was to provide an impetus on which to build future research protocols, rather than focus on weaknesses with any individual studies.Main Outcome MeasureExpert opinion was used to summarize limitations with commonly reported objective outcomes such as penile curvature, girth, and length along with imaging modalities and objective questionnaires. Appropriate study design and statistical analysis were also reviewed to discuss common pitfalls in the PD literature.ResultsThere are multiple shortcomings inherent to studying objective PD outcomes such as penile curvature, girth, and length. These include lack of standardized protocols for preintervention and postintervention assessment, interobserver and intraobserver variability, and lack of consistent definitions for what defines an objective outcome as clinically “meaningful” for patients. Similarly, imaging studies including penile ultrasound are subject to marked variation, thereby limiting their utility to measure predefined primary or secondary study outcomes including cavernosal artery hemodynamics and penile plaque size. Objective and validated questionnaires such as the Peyronie's Disease Questionnaire and International Index of Erectile Function require that patients have recently engaged in sexual activity, which is challenging for many patients as a result of penile deformity with PD. Finally, careful study design and statistical analysis (including appropriate study power) are imperative to ensure reliable results. Current shortcomings in the majority of studies contribute to the low level of evidence available for most PD interventions.Clinical ImplicationsFuture PD intervention studies should focus on optimizing study design and statistical analysis. Furthermore, authors must incorporate standardized protocols for assessing preintervention and postintervention outcomes.Strength & LimitationsThe current analysis and recommendations for future study are based on the expertise and opinion of the manuscript authors.ConclusionMultiple areas of weakness in study design, statistical analysis, and patient outcomes assessment limit the reliability of data derived from PD intervention studies in the modern era. The global themes identified herein should serve as a basis upon which to build future research protocols.

Abstract Background Glanular hypermobility (GH) or supersonic transporter (SST) deformity are occasionally encountered during penile prosthesis (PP) implantation, yet management strategies are underreported with minimal data available on surgical outcomes. Aim To describe a modified technique for glanulopexy to correct GH/SST in men undergoing PP placement and assess outcomes associated with this technique. Methods Glanulopexy was performed in men with GH/SST identified at the time of or following PP placement. A modification to previously described techniques was performed, whereby a suture is passed into the glans and secured to the tissue overlying the corpora through small incisions on the lateral aspects of the distal penile shaft. Outcomes Correction of the anatomic deformity (GH/SST), device infection, and changes in penile sensation were evaluated during post-operative follow-up. Results From 2014–2017, a total of 12 patients underwent modified glanulopexy for GH/SST. Nine (75%) were performed at the time of PP, while the remaining 3 were performed in a delayed fashion. At a median follow-up of 12 months (range 1–33 months), all patients with the device in situ demonstrated appropriate glanular positioning, and no patients reported changes in penile sensation. A single patient required device removal secondary to infection. Clinical Translation Glanulopexy with permanent suture successfully corrects severe GH or SST in men with inflatable PP without reduced penile sensation. Conclusions Strengths of the current study include the description of a simple, safe, and reproducible technique for GH/SST that adds minimal operative time and can be performed under local anesthesia when necessary. To our knowledge, this represents one of the largest reported series of glanulopexy outcomes reported in the literature. Limitations include that this is a single-surgeon series, there is limited follow-up, and lack of a comparison group. Further study with external validation is warranted to establish the optimal role for the procedure.
