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 Introduction Device malfunction remains a serious concern for patients with inflatable penile prosthesis (IPP), with pump failure being one of leading causes of revision surgery. Complete device replacement has been the traditional approach, but partial device replacement for the pump may offer a less invasive and cost-effective alternative, with potentially lower complication risk. Objective To evaluate the safety, efficacy, and clinical outcomes of pump replacement (with or without obvious tubing leak/fracture), manipulation or fluid addition in patients undergoing IPP revision surgery. Methods A retrospective review was conducted on patients who underwent IPP pump replacement with or without additional component exchange by a single surgeon, between January 2018 and April 2025. Thirty patients met the inclusion criteria. Clinical, intraoperative and postoperative data were collected and descriptively analyzed. Outcomes included postoperative infectious and non-infectious complication rates. Results The median age at revision was 77 years, with a median time to revision of 76 months post-implantation. Most common indications were frozen or pump difficulties (67%), pump + tubing damage (30%) and fluid addition requirement (10%). No intraoperative complications occurred. Postoperative complications were reported in 3 patients (10.0%), all due to mechanical malfunction, with no infections observed. Median time to complication was 24 months (IQR 7–72). One patient progressed to IPP explanation after successive revisions for impending erosion not thought related to pump manipulation. Another underwent complete replacement at 7 months for fluid leak from reservoir. A third required non-exchange revision at 24 months. The majority (91%) received Coloplast pumps. The median operative time was 53 minutes (IQR 43–70). Conclusions Pump replacement appears to be a safe and effective option for select patients, potentially reducing surgical morbidity and preserving viable components. The absence of infection in this series is reassuring, particularly in a revision setting where infection risk is amplified. Consideration of device age and patient specific factors is important in guiding the choice between partial and complete component exchange. Disclosure No

Abstract Introduction Inflatable penile prosthesis (IPP) implantation is a common and effective surgical treatment for erectile dysfunction. However, the presence of comorbidities and the use of anti-thrombotic therapy (AT) can complicate surgical decision-making. Due to the correlation between erectile dysfunction and cardiovascular disease, the preoperative comorbidities of surgical patients are important to examine. Objective The goal of this study was to assess the outcomes of IPP implantation in men on active AT therapy compared to a non-AT therapy cohort. Methods A retrospective analysis from 2015 to 2023 was conducted using data from three high-volume implant centers. The study focused on men who underwent three-piece IPP placement. Demographics, comorbidities, secondary procedures, drain information, and complications were recorded. The three centers each have different techniques and approaches to the surgery. Center 1 utilizes a penoscrotal approach, never places a drain, and places the reservoir in an ectopic location. Center 2 utilizes an infra-pubic approach, places a drain which remains in place for 3 days, and utilizes various reservoir locations depending on patient profile. Lastly, center 3 utilizes a penoscrotal approach, places a drain with removal when output is less than 50 mL over 8 hours, and places the reservoir in an ectopic location. Outcomes were analyzed using multivariate and univariate analysis. Results A total of 210 patients on active AT therapy and 128 non-AT patients were included. The AT and non-AT groups showed significant differences in baseline comorbidities, with the AT group exhibiting higher rates of cardiovascular disease, hypertension, and thrombosis (p<0.05). Among patients on anti-thrombotic therapy, 27.6% required revision surgeries and had increased rates of ectopic reservoir placement compared to the non-AT group (p<0.001). Despite these differences, there were no statistically significant variations in overall complication rates between the two groups. Drain output was notably higher in the AT cohort on postoperative days 1 (mean 110.5 cc vs 60 cc, p<0.001) and 2 (mean 78 cc vs 20 cc, p<0.001); however, hematoma rates remained comparable between both groups (p=0.667). Importantly, neither the type of anti-thrombotic therapy nor the surgical approach used appeared to influence postoperative outcomes. Eleven patients (5.2%) experienced complications in the AT arm and 5 patients (3.9%) experienced complications in the non-AT arm (p=0.793). Conclusions IPP implantation is feasible and safe in men on active anti-thrombotic therapy when performed in high-volume centers with appropriate perioperative management. Further studies with larger cohorts and longer follow-up are needed to refine protocols and determine long-term outcomes for these high-risk patients. Disclosure No

Abstract Introduction Penile prosthesis (PP) implantation is associated with high patient satisfaction in patients with medically refractory erectile dysfunction (ED). There remains a paucity in the literature regarding the temporal evolution of patient following PP surgery. Objective We sought to evaluate mechanical-associated outcomes in our Penile prosthesis (PP) cohort. Methods We analyzed our prospective penile registry that includes patient-completed surveys regarding device outcomes administered at 6 and 12-months after PP placement. We specifically examined the questions: “Have you had another [prosthesis] surgery since your first operation?”; and, “Does the device ever inflate or deflate on its own, if Yes how bothersome is this for you on a scale of 1-10 (1- very bothersome, 10 no bother)?”. Chart review was performed to identify pertinent variables including reservoir location (retropubic vs submuscular) and need for prosthesis revision for survey respondents. Results A total of 304 patients were enrolled in the registry. Of these, 101 completed the 6-month assessment and 79 completed the 1-year survey. The vast majority of PP were Coloplast (91.4%) utilizing the “classic” pump. Mean chart review follow up was approximately 3 years. One device was explanted for implant infection. No additional operations were reported for mechanical failure. Auto-inflation (AI) was reported in 38 patients at 6 months and 21 patients at 12 months. AI was most common in patients with submuscular reservoir placement (75.9% of those who reported AI at 6 months and 50% at 12 months respectively). The relative risk of developing AI was doubled in patients with a submuscular reservoir [2.2 (1.05-3.44); p < 0.001)]. Degree of bother had a reported median of 5 (3.75-9) at 6 months and became less bothersome after 12-months year with a reported median of 7 (5-9) (p = 0.230) [Fig. 1]. Conclusions Early Penile prosthesis mechanical failure requiring revision surgery did not occur in our cohort but patient-reported auto-inflation was identified more frequently than previously reported. Further study is warranted, but patients may benefit from pre-operative counseling regarding the incidence of auto-inflation. Disclosure Yes, this is sponsored by industry/sponsor: Coloplast.

Abstract Introduction Resistance training by recreational sportspeople in fitness settings has become increasingly popular worldwide, moreover an increasing landscape of social media (SM) influencers in bodybuilding have arisen since 2021, specially on short-duration videos (clips). Some Image enhancer drug users, including anabolic androgenic steroids (AAS) are known to mistrust medical health professionals and seek out information and advice from online sources. Objective we aimed to quantitatively assess the quality of social media videos as an information source for AAS usage in the general population. Methods A search was performed on the most popular short-clips social media platforms in the US (TikTok, YouTube) with the most searched terms for AAS. The first 50 results with any search term listed by relevance were selected in each platform. Video features (views, likes, subscribers) and video sources were collected. Each video included in the study was assessed using DISCERN score to quantify the source quality. Results A total of 100 videos were included and analyzed. Most videos (84%) were from non-health professionals (influencers/clip source/podcasts), only 7% of the videos came from a health educator/physician. Most videos were rated as “very poor” (85%) and “poor” (7%) According to the DISCERN classification, there was a statistically significant difference (p < 0.001) by both content creator type, and platform with the highest scores among physicians [37 (33-41)] and YouTube [19(17.7-30.2]. [Fig]. Conclusions Image-centric social media use is positively associated with the use of AAS. Despite the increasing number of information, the overall quality was poor. The misleading, inaccurate and incomplete information may pose a health risk to the viewers. Further efforts in health policies are strongly encouraged to assess this problem. Disclosure No.

Abstract Introduction Penile prosthesis (PP) implantation is associated with high patient satisfaction and improved sexual quality of life in medically refractory erectile dysfunction (ED). While reported patient satisfaction with this surgery is high, there are a variety of factors that can influence patient satisfaction after PP surgery. Objective We aimed to identify factors responsible for patient dissatisfaction after PP surgery. Methods We initiated a registry of patients undergoing surgery for placement of a PP. After consent, Perioperative study assessments and follow-ups were conducted. After surgery, patients were directed to fulfill a survey at 6 months and 12 months. Patients who completed both surveys were included in the analysis. Results A total of 304 patients had a PP placement, of these 101completed at least the first survey. Patients reported using their PP a median of 4 (2-8) times per month at 6 months, and 5 (2-9) at 12 months (p = 0.651). Main reasons of lack of use of the PP can be seen in Fig. 1A. The most frequent reported reason was lack of interest from partner (20.3% at 6-months, 18.8% at 12-months). Patient reported reasons for dissatisfaction are seen in Fig. 1B. Examples include penile pain (19% at 6-months, 11% at 12-months), difficulty with orgasm (39% at 6-months, 37% at 12-months), unsatisfactory penile cosmesis (28% at 6-months, and 25% at 12-months), problems inflating of the prosthesis (14.9% at 6-months, and 21.5% at 12-months), and problems deflating of the prosthesis (33.7% at 6-months, and 31.6% at 12-months). Despite these concerns, most patients found PP easy to use (83.2% at 6-months, and 82.1% at 12-months) and a reported a very or somewhat natural sensation with their erections (66.4% at 6-months, and 62.8% at 12-months) Fig. 1C. Conclusions There was a higher than anticipated rate of penile pain, difficulty achieving climax, and unsatisfactory cosmesis that warrant further investigation. Despite this, the majority of patients found their PP easy to use and a reported natural sensation when having erections. Disclosure Yes, this is sponsored by industry/sponsor: Coloplast.

Abstract Introduction Penile prosthesis (PP) implantation is associated with high patient satisfaction in patients with medically refractory erectile dysfunction (ED). There remains a paucity in the literature regarding the temporal evolution of patient satisfaction and well-being following PP surgery. Objective We aimed to identify factors responsible for patient satisfaction after surgery. Methods We initiated a registry of patients undergoing surgery for placement of a PP. After consent, perioperative study assessments and follow-ups were conducted. After surgery, patients were directed to a survey at 6 months and 12 months. Patients who completed both items were included in the analysis. Results A total of 304 patients had a PP placement, of these 101 completed the initial surveys. Overall patient satisfaction was favorable and durable and 6- and 12-months (87% and 82% respectively, p = 0.11). Confidence with device use was reported by 92% at 6 months, without significant change at 1 year (vs. 95%, p = 0.91). At 6 months, 81% of patients reported that their PP met or exceeded expectations, 83% of patients reported that they would undergo the procedure again, and 80% would recommend to a friend/family member. [Figure 1] At 6 months, 78 patients (77%) reported a moderate to high improvement in their overall sense of well-being related to their PP. This percentage further increased to 91% at 12-months (p < 0.001). Additionally, 36% of patients reported that they had made significant improvements to their overall lifestyle since receiving the PP, and this increased to 48% by 12 months post-operatively (p = 0.082). Conclusions Penile prosthesis satisfaction is evident and durable as early as 6 months following surgery. Factors such as perceived overall well-being continued to significantly improve past 6 months, and nearly half of patients reported overall lifestyle improvement following surgery.
