Abstract Introduction Sexual therapy for male sexual dysfunction has been used to help patients address a variety of sexual dysfunction-related conditions. While this intervention is frequently recommended for patients by male sexual health experts, the rate of adherence to the recommended therapy and associated factors is unknown. Objective To understand factors leading to completion of sex therapy consultations and barriers that prevent it. Methods A survey was developed by experts in the management of male sexual dysfunction and sex therapy at our institution. The survey included questions focusing on the decision to pursue sex therapy (or not), barriers or facilitating factors, patient perceptions regarding the referral, and treatment success. A retrospective chart review was performed to identify those patients who were referred for sexual therapy after undergoing evaluation for male sexual dysfunction at an academic Men’s Health urology clinic from 2017 - present. The survey was mailed out to these patients, and respondent survey data was compiled to evaluate survey responses. Results To date, 23 patients completed the survey (20% response rate). Sixty-five percent of survey respondents were ≥ 50 years of age, 87% were straight, and 71% were married. Reasons for sex therapy referral were frequently multi-factorial and included erectile dysfunction (65%, n=15), low libido (43%, n=10), ejaculatory dysfunction (39%, n=9), performance anxiety (30%, n=7), relationship problems (30%, n-7), and genital pain (14%, n=3). Seventy-eight percent of patients (n=18) felt that sex therapy consultation was a reasonable part of their treatment plans. Six (26%) patients did not attend their recommended sex therapy consultations. Reported barriers included sense of shame (n=2), embarrassment (n=2), scheduling conflicts (n=1), lack of anticipated benefits (n=1), and feeling dismissed by the referring provider (n=2). Those who attended sex therapy frequently reported the perception that referral made sense based on their symptoms (n=10, 59%) and/or a feeling of desperation to “do anything do get better” (n=11, 65%). Seventy-eight percent of patients who attended sex therapy found it helpful and would recommend it to a friend with a similar concern. Conclusions The majority of male patients who are referred to sexual therapy feel it is beneficial. However, one in four men choose not to pursue this line of treatment despite recommendations from their treating physicians. Future work is needed to address barriers to pursuing sex therapy.

Abstract Introduction Sexual Health Curriculum (SHC) in medical schools has been insufficiently training medical students for many years. While most medical schools report teaching a SHC, many medical students and residents report being inadequately trained in sexual health. This has led to infrequent physician screening for sexual problems due to insufficient knowledge and a lack of training about sexual function and dysfunction. Objective To investigate the current body of literature for changes in SHC in medicals schools in the last 20 years, and to identify any discrepancies between SHC taught in medical school and resident and medical student comfort in treating Sexual Health Dysfunction. Methods A literature review was conducted in PubMed on “sexual health education in medical school”, and of 16,962 results 37 relevant papers published in the U.S. and Europe were identified and analyzed. Results In 2003 86% of medical schools reported teaching over 3 hours of SHC, but by 2021 only 65% of students and 50% of PGY 4/5 Urology residents recalled a dedicated SHC in medical school. Consistently 50% of medical students are unsatisfied with their SHC, 52% are rarely or never evaluated on their sexual history taking skills, and 7% report not learning about human sexuality at all. Most German medical students believe that sexual health courses should be mandatory. Medical students have overall positive attitudes towards sexual and gender minority populations but lack adequate knowledge, especially about transgender and intersex health. Only 55% of 3rd/4th year OBGYN residents reported feeling comfortable in performing a targeted sexual dysfunction exam, and 66% of residents in Family Med, IM, OBGYN, and Psych had no previous educational experience in sexual problem management. Conclusions Sexual health curriculum in medical schools has not significantly improved in the last 20 years, leading to students and residents inadequately prepared to treat sexual health dysfunctions. The adoption of previously proposed SHC competencies for medical schools should be strongly considered.

Abstract Introduction Collagenase Clostridium Histolyticum (CCH) is an FDA-approved treatment for Peyronie’s Disease (PD). Based on phase-3 trials, the recommended treatment course consists of 8-injections over the course of roughly 18-20 weeks. While its efficacy has been established, less is known about patient-specific reasons for electing to discontinue CCH injection therapy. Objective To evaluate patient-reported factors associated with premature CCH discontinuation. Methods We queried a database of all patients (n=406) who underwent CCH at a single institution from 2014-2021. Patients who did not complete the recommended 8 injections were identified, and a detailed review was undertaken to determine causes of discontinuation. Patients were excluded from our analysis for the following reasons: deceased at the time of chart review, declined to participate, or could not be reached in 3 phone calls. Results Out of 406 patients who underwent Xiaflex treatment at our single institution, 133 did not complete 8 injections (32.8%). The mean number of CCH injections was 4.42 (SD 1.65). The most common reasons for discontinuing Xiaflex were satisfactory curve reduction (27%), unsatisfactory curve reduction (21%), bothersome side effect (15%), and decision to pursue surgery (12%) [Figure 1]. Other less common reasons included other health concerns, pausing treatments due to the Covid-19 pandemic, high treatment cost, transferring care elsewhere, and lack of awareness that more injections were indicated. Conclusions In our single institution study, we find that nearly 1/3 of patients who begin Xiaflex injections will not complete the full recommended treatment course. Understanding the reasons for discontinuation can help providers better stratify patients for Xiaflex treatment versus other modalities. In addition, given previous studies that indicate that 2/3 of men who fail to achieve a 20% curve reduction after their first 4 injections will go on to achieve this curve reduction after their final 4 injections, our data points to the potential impact of improved patient education for the 21% of individuals who discontinue due to unsatisfactory curve reduction (Alom et al 2021).

Abstract Introduction Independently performed procedures by well-trained advanced practice providers (APP) facilitate access to specialized care. We sought to compare outcomes between physicians and APPs with intralesional collagenase clostridium histolyticum (CCH). Objective Compare outcomes of CCH injections based on injection provider. Outcomes included curvature improvement and adverse events. Methods Men receiving CCH between 2014-2021 at our institution by four physicians and four APPs were included in an IRB-approved database. CCH was delivered as a series of 8 injections per protocol. Patient demographics, procedural-related adverse events, and curvature changes were recorded. The “APP-ratio” is defined as percentage of total injections administered by an APP per patient. Results After excluding patients who did not complete the entire CCH course or return for final assessment, 150/406 patients were analyzed. Mean baseline penile curvature was 66.2° (SD 23). Mean absolute and percent improvements in curvature were 21.7° (SD 18) and 33% (SD 27). The mean APP ratio was 69%, and 133 patients (89%) had at least 25% of their injections performed by an APP. There was no significant difference (p=0.65, p=0.39) in absolute or relative curvature improvement based on the APP-ratio [Figure 1]. There was also no difference in adverse events (pain, swelling, and hematoma). Conclusions In our high-volume CCH practice, APPs achieve the same outcomes and safety compared to physicians. Greater training efforts expand access to care for patients with PD. Disclosure No

Abstract Introduction Since the FDA approval of Collagenase Clostridium Histolyticum (CCH), few studies have been able to identify variables which predict curve improvements, with baseline extent of curvature most highly correlated. In addition to extent of baseline curvature, our team has previously identified curve direction and plaque calcification as additional predictive variables. We therefore sought to create an integrated predictive model which incorporated several factors to better estimate anticipated outcomes. Objective To report outcomes of a novel scoring system designed to better predict outcomes of men undergoing CCH injections for Peyronie’s disease (PD). Methods A prospective database has been maintained of men undergoing CCH injections for PD. Data were reviewed to identify variables predictive of curve improvements in men with isolated curvature as well as among those with key characteristics, including indentations, hourglass deformities, penile tapering, and calcification. A predictive model was subsequently developed to improve correlations between disease factors and subsequent CCH outcomes. The final model (CLINiC Score) assigned points as follows: +1 point for every 10 degrees of curvature (C for Curvature), +5 points for penile narrowing >25% (IN for INdent), +3 points for narrowing 0-25%, -4 points for pure lateral curvatures (L for Lateral), and -2 points for plaque calcification (C for Calcification). Patients were assigned scores based on the CLINiC model, and results were correlated with final curve outcomes. Results A total of 476 PD men were included in the current analysis. Baseline variables for the cohort included a mean age of 55.6 yrs (SD 10.9), PD duration 31.9 months (SD 61.4), composite curvature 64.6 degrees (SD 23.9), 47% with indentations, 42% with hourglass deformity, and 17% with calcification. The mean CLINiC score for the cohort was 6.9 (SD 3.4). For the overall cohort, the use of the CLINiC score increased the correlation coefficient from 0.35 to 0.46 (r-squared 0.13 vs 0.21), with a predictive linear formula of 2.1 - 3.2 * CLINiC score. The difference was more pronounced among a subset cohort of men who had pure lateral curvatures, plaque calcification, or narrowing deformity. In comparing the CLINiC predictive model to baseline curve alone, the correlation coefficient increased to 0.54 (r-squared 0.29, p<0.0001) compared to 0.38 (r-squared 0.15, p<0.001). The linear equation to predict curve improvement outcomes using the CLINiC score was 2.2 - 3.5 * total CLINiC score. Conclusions Use of a novel scoring system (CLINiC) improves upon baseline curvature alone to predict post-CCH curve improvements, with the difference more pronounced among men with pure lateral curvatures, plaque calcification, and/or narrowing deformities. External validation is warranted. Disclosure No

Abstract Introduction Limited data currently exist on the role and efficacy of additional series of collagenase clostridium histolyticum (CCH) injections among Peyronie’s disease (PD) men who have previously failed a first series of injections. We have previously reported outcomes of men undergoing a more aggressive protocol for CCH injections. We therefore sought to evaluate results of men who had previously failed CCH injections to determine if they would respond to a repeat course using a more aggressive protocol. Objective To evaluate outcomes of a novel, aggressive protocol for CCH injections among men who had previously failed 6-8 CCH injections using a traditional approach. Methods A randomized, controlled trial (NCT05108558) is ongoing. All participants had previously failed to achieve ≥20% curvature improvement with 6-8 prior CCH injections. Men are randomized 3:1 to receive either CCH + traction (RestoreX) + sildenafil (treatment) up front or initial observation followed by treatment (controls). Outcomes are subsequently compared between treatment and control groups. Key measures include objective curve improvements, and standardized / non-standardized questionnaires, with assessments obtained at baseline, 6-weeks after completion of CCH (treatment arm), after the no treatment period (controls), and at 1 year. Results A total of 11/40 men have been randomized to date, with one having completed four series of CCH injections, three completing one series, and three completing two series. The average age of the cohort is 64.4 years, with a mean PD duration of 28.1 months. Mean baseline curvature was 82.9 degrees (composite curve). The average estimated improvement with prior CCH injections (before enrollment in the current study) was 10%. Preliminary outcomes of men who had completed one series and had a follow-up curve assessment available (n=3) demonstrated an absolute improvement of 28.3 degrees (42%). Of the one patient who completed four full series, the absolute curve improvement was 55 degrees (65%). The overall range of improvement among the four men was 20 to 55 degrees or 31 to 65%, with no patients failing to experience improvements thus far. Conclusions Preliminary data suggests that a repeat course of CCH using a previously described more aggressive administration protocol is effective at improving penile curvature in the majority of men. It is unclear if the improvements are due to the difference in administration protocol, or due to the repeat course of CCH alone. Given the very preliminary nature of the current results, additional data, including external validation, are warranted.

Abstract Introduction Since the FDA approval of Collagenase Clostridium Histolyticum (CCH) for the treatment of Peyronie’s Disease (PD), there has been significant debate as to its role and comparable efficacy in relation to surgical therapies. Specifically, investigators have compared relative utilization, costs, and outcomes with varying conclusions. Objective To compare various objective and subjective outcome measures between men undergoing CCH or surgery for PD. Methods A randomized, controlled trial (NCT04786106) is ongoing. Participants are randomized 1:1 to receive either CCH + traction (RestoreX) + sildenafil or penile surgery (plication and/or incision and grafting) + traction + sildenafil for PD. Objective, standardized (International Index of Erectile Function [IIEF] and Peyronie’s Disease Questionnaire [PDQ]), and non-standardized assessments are obtained at baseline, and post-treatment at 3, 6, 12, 24, 36, 48, and 60 months. Key outcomes include differences in standardized questionnaires, penile curvature, penile length, subsequent interventions, and non-standardized questionnaire responses. Curvature is measured in two planes and summed to provide a composite curvature. Penile length is measured from pubic symphysis to corona. All therapies were stopped prior to the 3-month time point (i.e. traction and sildenafil). Results A total of 40 men have been randomized, with 3-month data available on 27 men (CCH=14, surgery=13) and 12-month data on 15 men (CCH=5, surgery=10). Mean age at enrollment was 54.9 years, PD duration 36.6 months (mo), composite curvature 72.3 degrees (deg), and penile length 12.7 cm. All baseline variables were statistically similar between cohorts. Regarding the primary outcome, post-treatment, CCH men reported higher overall satisfaction (3-months: 100% vs 88% surgery, p=0.16; 12-months 80% vs 70%, p=0.52). For secondary outcomes at 3 months, the median differences between CCH and surgery respectively were: IIEF-EFD (+3.5 vs +7, p=0.64), PDQ-physical (-10 vs -7, p=0.47, note: lower is better for PDQ scales), PDQ-pain (-2 vs -0.5, p=0.21), PDQ-bother (-4.5 vs -8.5, p=0.60), length change (+1.0 vs -0.5 cm, p<0.01), curvature absolute change (-26 vs -65 degrees, p=0.01), and curvature percentage improvement (46% vs 84%, p<0.01). More CCH men felt that treatment improved sexual function (86% vs 79%, p=0.45), erectile function (64% vs 56%, p=0.04), penile length (36% vs 6%, p<0.0001), and had less impact on sensation (14% less sensation vs 56%, p<0.01), while surgery men were more likely to report satisfaction with curvature (75% vs 64%, p=0.52). 100% of men in both groups would recommend treatment to a friend at 3 months, whereas 100% of CCH vs 70% of surgery men would recommend their therapy at 12 months. When asked which treatment they would pick if they could start again, at 3 months 100% of CCH men reported CCH and/or traction, while 79% of surgery men indicated surgery. Conclusions Preliminary data suggests that, when compared to surgery, CCH results in higher overall satisfaction (not statistically significant), decreased curve improvement, improved penile length, and fewer impacts on erectile function and sensation.

AbstractBackgroundCollagenase Clostridium histolyticum (CCH) has been proven effective in multiple subpopulations of PD men; however, no studies have evaluated its role with congenital penile curvature (CPC).AimTo evaluate the safety and efficacy of CCH in men with CPC.MethodsA prospective registry was queried of men undergoing CCH injections at our institution. Beginning in 2016, CCH was administered to CPC men using a similar protocol to PD. A comparative analysis was performed between cohorts to evaluate the safety and efficacy of therapy.OutcomesObjective measures included penile length and curvature, while subjective outcomes included standardized (International Index of Erectile Function and Peyronie’s Disease Questionnaire) and non-standardized assessments. Curvature outcomes were categorized as follows: 1 – included all men, with the most recent assessment considered final, and 2 – only men who had completed eight CCH injections or stopped early due to satisfaction.ResultsFrom 2014 to Oct 2021, a total of 453 men (408 PD, 45 CPC) underwent one or more CCH injections. In comparing cohorts, CPC men were younger (33 vs 58 years, p<0.0001), had lesser baseline curvatures (52.5 vs 65°, p<0.01), more ventral curves (25.7 vs 9.2%, p<0.01), and longer penile lengths (12.5 vs 12.0 cm, p=0.04). Following treatment, both cohorts experienced similar curvature improvements. Specifically, PD men experienced 20-25° or 33-35% improvements depending on definition compared to 25-30° or 40-50% in CPC men (all p-values >0.05). CPC and PD men also demonstrated similar changes on standardized questionnaires, with the exception of the Psychological and Physical subdomain, which was more improved in CPC men (-11 vs -4, p<0.01). Baseline curvature was positively correlated with greater absolute (degree) and relative (percent) improvements. Adverse events were similar between groups after controlling for confounders.Clinical ImplicationsCCH may be safely and effectively administered in men with CPC. These data provide the first evidence for the efficacy of a non-surgical therapeutic option in this cohort.Strengths and LimitationsStrengths – large, prospective series with standardized assessments; Limitations - non-randomized study, short-term follow-up, and lack of standardized method to differentiate CPC from PD.ConclusionsCCH may be safely and effectively administered to men with CPC, with similar success rates compared to PD. Increasing curvature was associated with greater absolute (degree) and relative (percent) improvements, supporting the role for CCH in men with mild, moderate, or severe curvatures. External validation is warranted prior to routine implementation.

AbstractBackgroundThe advent of antibiotic-coated devices has reduced the rate of inflatable penile prosthesis (IPP) infections; however, this may have altered microbial profiles when infections do occur.AimTo describe the timing and causative organisms behind infection of infection retardant–coated IPPs in the context of our institution’s perioperative antimicrobial protocols.MethodsWe retrospectively reviewed all patients undergoing IPP placement at our institution from January 2014 to January 2022. In all patients, perioperative antibiotic administration was congruent with American Urological Association guidelines. Boston Scientific devices are impregnated with InhibiZone (rifampin and minocycline), and all Coloplast devices were soaked in rifampin and gentamicin. Intraoperative irrigation was performed with betadine 5% irrigation prior to November 2016 and with vancomycin-gentamicin solution afterward. Cases involving prosthesis infection were identified, and variables were extracted from the medical record. Descriptive and comparative statistics were tabulated to identify clinical characteristics, including patient comorbidities, prophylaxis regimen, symptom onset, and intraoperative culture result. We previously reported an increased infection risk with Betadine irrigation and stratified results accordingly.OutcomesThe primary outcome was time to infectious symptoms, while the secondary outcome was description of device cultures at the time of explantation.ResultsA total of 1071 patients underwent IPP placement over 8 years with an overall infection rate of 2.6% (28/1071). After discontinuation of Betadine, the overall infection rate was significantly lower at 0.9% (8/919) with a relative risk of 16.9 with Betadine (P < .0001). Primary procedures represented 46.4% (13/28). Of 28 patients with infection, only 1 had no identified risk factors; the remainder included Betadine at 71% (20/28), revision/salvage procedure at 53.6% (15/28), and diabetes at 50% (14/28). Median time to symptoms was 36 days (IQR, 26-52); almost 30% of patients had systemic symptoms. Organisms with high virulence, or ability to cause disease, were found in 90.5% (19/21) of positive cultures.Clinical ImplicationsOur study revealed a median time to symptoms of just over 1 month. Risk factors for infection were Betadine 5% irrigation, diabetes, and revision/salvage cases. Over 90% causative organisms were virulent, demonstrating a microbial profile trend since antibiotic coating development.Strengths and LimitationsThe large prospectively maintained database is a strength along with the ability to follow specific changes in perioperative protocols. The retrospective nature of the study is a limitation as well as the low infection rate, which limits certain subanalyses from being performed.ConclusionIPP infections present in a delayed manner despite the rising virulence of infecting organisms. These findings highlight areas for improvement in perioperative protocols in the contemporary prosthetics era.

Abstract To determine effects of sexual health curriculum (SHC) in medical school on future urology specialty and subspecialty selection, residents, fellows, and practicing urologists completed a 15-question survey regarding their exposure to SHC during medical school, topics covered, and the influence of mentors in career choice. 95 respondents, primarily post-graduate year 4 and 5 (46%), completed the survey. Approximately 50% recalled dedicated SHC during medical school with 46% planning to pursue fellowship training in sexual medicine/reconstruction. Topics commonly covered included reproductive anatomy/physiology and sexual history-taking, while respondents rarely recalled topics such as sexual aids/toys and pornography. Only 25% felt SHC provided an adequate fund of knowledge to address patient’s sexual health concerns, and only 14% believed SHC influenced their decision to pursue urology. Individuals pursuing fellowship were more likely to have an attending mentor, a mentor with expertise in sexual dysfunction, and considered their mentor as important or very important in their decision to subspecialize (p<0.05). Most urology trainees do not have strong exposure to SHC during medical school and cite mentorship as more important in the decision to pursue subspecialty training. These data support the need for a standardized formal SHC and continued exposure to sexual health experts during training.
