Abstract Introduction The EROS (Erectile Restoration Outcomes and Satisfaction) registry provides prospective, questionnaire-based follow-up after IPP, established in 2020. Objective We sought to assess general trends in the open-ended responses portion of the questionnaire. Methods Data were collected from 2020 to 2025, with a total of 568 responses. The survey included six open-ended questions pertaining to lifestyle change since IPP, reasons not to repeat the procedure, impediments to use, dissatisfaction, what patients wish they had known more about the procedure, and other recommendations. Evaluable data included 6-month responses from Rochester, Jacksonville, and Phoenix. Results Open-ended feedback was given by 66% of patients on what they wished they had known, 54% gave other recommendations, 38% gave lifestyle feedback, 7% elaborated upon reasons not to use, 3% on reasons for dissatisfaction, and 2% on reasons they would not repeat IPP. There was an overall very positive response (“Significant Improvement”, n=74.3%) from those who underwent the IPP placement, with some patients reporting that it was far more convenient than other forms of treatment, and even increased spontaneity in their sexual lives, leading to improved relationships. Among the reported responses are increased confidence (n=39.4%), increased sexual activity (n=13.3%), and improved health and exercise levels (n=6.6%). When questioning patients about why they would not repeat the procedure and what their sources of dissatisfaction were, among those who responded to each question (n=12, n=16), the most frequently reported complaint was the exaggeration of pre-existing curves (n=41.7%, n=25.0%), particularly due to Peyronie’s disease. When questioned about what prevents use, the main responses were partner-related or due to personal problems (n=45.2%). The patients did not have many recommendations, but hoped for a better way to deflate and inflate the device (n=20.4%) and reported adequate pre-operative education and use of the pump. The table below outlines the categories of responses and the percentage of each keyword reported per question type. Conclusions In addition to standard pre-operative IPP counseling, providers should also focus on potential difficulties with device inflation/deflation, length loss (IPP not in the glans), pain/ recovery expectations, the potential for new or worsened curve (erect or flaccid), and potential changes in sensation. IPP satisfaction is high, as only 2% of patients gave responses on why they would not repeat the IPP, with many men expressing an increased level of overall confidence. Disclosure No

Abstract Background Erectile dysfunction (ED) is a known precursor and sequela of cardiovascular disease (CVD), with ED severity predicting CVD severity. Aim This study aimed to evaluate the utility of ceramide levels in patients with ED. Methods We initiated ceramide testing in all patients with ED. We retrospectively analyzed ceramide levels from electronic records and stratified by severity of symptoms using the erectile function domain of the International Index of Erectile Function (IIEF). Outcomes The study aimed to determine whether abnormal ceramide levels were associated with ED severity and increased cardiovascular risk. Results Three hundred and fifty-four patients were reviewed, of whom 253 (71.5%) had moderate or higher ED. A statistically significant difference in abnormal ceramide values was found in patients with moderate to severe symptoms, and the odds of getting an abnormal ceramide test were increased based on the IIEF scoring alone (odds ratio [OR] 2.3 [1.04-5.12]; P-value = .034). Clinical Implications Serum ceramide testing could be beneficial in identifying cardiovascular risk in men with ED, potentially prompting cardiac referrals and lifestyle modifications. Strengths and Limitations The strengths of this study include a large sample size and the use of a well-established scale, while the limitations include the retrospective nature of the study and the need for further research to validate the findings. Conclusion Patients undergoing management for ED may benefit from serum ceramide testing and subsequent cardiac referral.

Abstract Background Multiple guideline-based surgical treatment options for Peyronie’s disease (PD) exist, including penile plication and plaque incision or excision and grafting. Surgical incision type may differ depending upon location and severity of curve, planned concomitant procedures, and surgeon preference. Aim To evaluate postoperative wound complications comparing outcomes between ventral and subcoronal incisions in patients undergoing tunica albuginea plication (TAP) and plaque incision or partial excision and grafting (PG) for PD. Methods A single-surgeon, single-center retrospective chart review was conducted on all patients undergoing TAP or PG from 2019 to 2023. Patient demographics, including previous PD treatments, were recorded. A Mann–Whitney U test was utilized to determine differences in wound complication rate, median curvature improvement, and remaining postoperative curvature between ventral and subcoronal approaches. Outcomes Wound complication was classified as any dehiscence and/or wound exudate suspicious for infection within the first 3 months postoperatively. A secondary analysis was performed comparing these outcomes between TAP and PG. Results In the analysis, 189 patients were included, including PD straightening surgery, including 125 patients who underwent TAP (66%) and 64 patients (34%) who underwent PG. Among all cases, 49.7% underwent ventral incision (N = 94) and 50.3% (N = 95) underwent subcoronal incision. A total of 12 patients (6.3%) experienced a wound-related complication postoperatively (range 3-23 days), including 9/94 (9.6%) in the ventral incision cohort and 3/95 (3.2%) in the subcoronal cohort (P = 0.081). All the patients were treated with oral antibiotics and two patients required closure under local anesthesia (both in the ventral incision cohort). Secondary analysis did not reveal any significant difference in outcomes between TAP and PG cohorts with respect to wound complications. Clinical Implications While we did not identify a statistically significant difference, most of our wound complications, including infection and/or dehiscence, were seen in those undergoing a ventral penile raphe incision. Despite this, the rate of wound complications with either incisional approach as low. Strengths and Limitations Our report represents a large cohort of patients treated with surgical straightening for PD, and to our knowledge is one of the first to compare wound complications between ventral and subcoronal incisions. Limitations include the retrospective single-surgeon series without randomization, lack of power analysis, and heterogenous classification of wound complications. Conclusion Both ventral penile raphe and subcoronal (degloving) incisions can be considered for penile straightening procedures to correct PD curvature deformity with a low risk for serious wound-related complications.

Abstract Background Chlorhexidine gluconate (CHG) (0.05%) has recently been suggested as a dip and irrigation solution at time of inflatable penile prosthesis (IPP) surgery. Aim This study evaluated infection rates before and after implementing CHG protocol while investigating concurrent risk factors contributing to post operative infections. Methods A retrospective, consecutive cohort study was performed that included patients who underwent insertion of a Coloplast Titan IPP including both virgin and revision cases between 2021 and 2024. Cases performed from January 2021 to August 2022 utilized rifampin/gentamicin for dip and vancomycin/gentamicin for irrigation (ABX), whereas those from October 2022 to May 2024 utilized CHG for both dip and irrigation. Perioperative risk factors including dip and irrigation solution used at time of surgery were compared between groups. Outcomes We defined the incidence of postoperative infection and risk factors associated with infection in each group. Results The incidence of infection was significantly higher in the 0.05% CHG group (13/377) compared to the ABX group (0/320) (P < .001). When analyzed separately by subgroup, virgin cases treated with CHG for dip and irrigation demonstrated a significantly higher infection rate (7/315) compared to those in the ABX group (0/280) (P = .012). Similarly, in revision cases, the CHG group also exhibited a significantly higher infection rate (0/40) than the ABX group (6/62) (P = .043). Univariable analysis of the CHG cohort identified three significant risk factors for infection: diabetes mellitus (DM), extended operative time (OP), and revision surgery (P = .003, .001, and < .001, respectively). Multivariable regression analysis revealed that patients with DM had a 5.7-fold increased risk of infection (OR: 5.70, P = .004), while those undergoing revision surgery faced a 5.3-fold higher risk (OR: 5.26, P = .004). Additionally, each minute increase in OP was associated with a 1% higher infection risk (OR: 1.01 per minute, P = .007). These associations remained significant after adjusting for all variables in the model. Clinical Implications Prosthetic surgeons should be cautious about adopting 0.05% CHG for both dip and irrigation in the absence of strong clinical evidence demonstrating its non-inferiority to antibiotic solutions. Strengths and Limitations This is the first clinical study reporting infection rates after IPP surgery using 0.05% CHG for both dip and irrigation. While retrospective and non-randomized, we present a relatively large sample size of patients. Conclusions Our findings identify four risk factors for penile prosthesis infection: usage of the 0.05% CHG solution for dip and irrigation solution of Coloplast hydrophilic-coated devices, DM, revision surgery, and extended OP.
