Abstract Introduction 0.05% Chlorhexidine Gluconate (CHG) has gained popularity as an irrigant for inflatable penile prosthesis (IPP). In vitro data has explored interactions between CHG and minocycline/rifampin impregnated (M/R) IPP surfaces Objective We aimed to assess clinical infection rates between intraoperative CHG use and M/R impregnated IPPs in a large multi-institutional cohort. Methods We conducted a retrospective analysis of 1,604 patients who underwent IPP implantation across 12 referral centers. Data collection spanned from January 1, 2017 to March 1, 2024. Each surgeon contributed patients who underwent IPP implantation with the use of CHG as an irrigant and an equal number of consecutive control patients where CHG was not used. The primary outcome was explant for postoperative infection. Patient demographics were compared using chi squared testing and logistic regression analysis was performed to assess factors associated with infection. Results M/R impregnated devices accounted for 695 cases. The incidence of infection with intraoperative CHG use was 1.7% (5/289) and was not significantly different from the 2.5% (10/406) infection rate in those without CHG (p=0.429). Patients with infection had a higher prevalence of hypertension and history of priapism (Table 1). On logistic regression analysis, only a history of priapism was significantly associated with an increased odds of infection (OR 11.47, 95%CI 2.25-58.40, p=0.003). Intraoperative CHG use was not associated with postoperative infection (OR 0.69, 95%CI 0.2-2.06. p=0.514). Conclusions In a large multi-institutional cohort, there was no difference in infection rate for patients with or without intraoperative CHG use, consistent with prior in vitro findings.

Abstract Introduction There is wide variation in male fertility preservation practices. While physician preference accounts for some of this diversity, practice patterns often reflect multiple extrinsic factors including patient demographics, equipment availability, laboratory protocols, and state law. Objective We sought to characterize national trends in sperm retrieval and storage across reproductive urology practices in the United States. Methods An anonymous 34-item survey characterizing provider demographics, practice settings, fertility preservation procedures, andrology laboratory practices, and cryopreservation expenses was designed. Practicing reproductive urologists were identified using information available through professional societies. Our survey was constructed using the Qualtrics platform and distributed electronically between October 2024 and May 2025. Results 39 responses were received by urologists practicing across 21 states (response rate: 21%, n=189). A majority (74%, n=29) of survey responders practiced at academic medical centers, with others practicing at non-academic hospitals (8%, n=3) and private practices (13%, n=5). The most common indications for fertility preservation reported included oncologic care (42%), gamete storage for planned ART (31%), transgender care (18%), pre-vasectomy sperm banking (10%), and pre-deployment banking for military personnel (5%). Nearly all providers performed microsurgical sperm retrievals (97%, n=38, Figure) and oncologic testicular sperm extractions (85%, n=33) when indicated. More than half of providers offered conventional testicular sperm extractions (72%, n=28), microsurgical epididymal sperm aspirations (59%, n=23), testicular sperm aspirations (56%, n=22), penile vibratory stimulation (54%, n=21), or percutaneous epididymal sperm aspirations (52%, n=20). Fewer providers offered post-mortem sperm retrieval (49%, n=19), pre-pubertal testicular tissue cryopreservation (36%, n=14), or electroejaculation (31%, n=12). Most respondents (62%, n=24) had access to an on-site andrology laboratory. Semen analyses were evaluated using manual (53%, n=20), computer-assisted (11%, n=4), or combinatorial methods (26%, n=10). Though many (37%, n=14) providers were uncertain about institutional costs for semen specimen processing, a plurality of respondents (40%, n=15) reported fees ranging from $100-500 with the remainder (23%, n=9) reporting fees exceeding $500. Respondents most frequently reported semen storage fees ranging between $100-300 per year (39%, n=15), while approximately a third (31%, n=12) estimated these costs to range between $300-600 per year. However, 18% (n=7) of respondents reported higher costs for specimen storage and 13% (n=5) were uncertain about the expense of this service. Conclusions This multi-institutional, geographically diverse survey reveals significant variation in reproductive urology practice patterns and cost associated with semen analyses and storage. Future studies will explore differences in practice patterns to better understand the factors influencing this variation and their effect on male reproductive healthcare. In the absence of society guidelines, reproductive urologists must collaborate, share best practices, and maintain price transparency to ensure sperm retrieval remains accessible and affordable.

Abstract Introduction The optimal antimicrobial prophylaxis strategy for inflatable penile prosthesis (IPP) surgery remains a subject of ongoing investigation. Our institution recently discontinued the use of chlorhexidine gluconate (CHG) and returned to traditional antibiotic-based prophylaxis protocols. Objective To evaluate infection rates following the reinstitution of antibiotic-based prophylaxis after discontinuing CHG in IPP surgery. Methods We conducted a retrospective, consecutive cohort study of patients who underwent Coloplast Titan IPP insertion between May 2024 and May 2025. The antibiotic prophylaxis protocol consisted of rifampin/gentamicin device dipping and vancomycin/gentamicin irrigation. Primary and revision cases were analyzed separately. Results A total of 188 patients underwent IPP insertion during the study period, including 119 primary implantations and 69 revision procedures. Mean patient age was 69.6 ± 11.5 years, BMI was 27.6 ± 4.2 kg/m2, and operative time was 67.1 ± 24.1 minutes. No infections occurred in the primary implantation cohort. One infection (1.4%) occurred in the revision group in a diabetic patient with prolonged operative time (176 minutes). Compared to our previously published data using CHG, infection rates decreased significantly in the revision group (1.4% vs. 9.67%, p < 0.001), while the primary group showed a numerical reduction from 2.22% to 0%. Conclusions The reinstitution of antibiotic following discontinuation of CHG resulted in significantly lower infection rates, particularly in revision cases. These findings support the continued use of antibiotic dipping and irrigation protocols for IPP surgery as a safe and effective strategy for infection prevention. 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 Glans ischemia and subsequent necrosis is a rare but devastating complication of inflatable penile prosthesis (IPP) placement. Differentiating true glans ischemia from severe ecchymosis is often difficult to distinguish, yet it remains paramount given the glans ischemia principle: “when in doubt, take it out.” Objective We present several clinical scenarios and associated postoperative images wherein there was concern for post-IPP glans ischemia based on initial clinical examination. In addition, we review pertinent clinical factors that can be used to help distinguish between greater than “average” glans ecchymosis and true ischemia. Methods We present four cases from 2025 and describe clinical factors likely responsible for increased glans discoloration. Results Traditional risk factors for glans ischemia are constrictive IPP wrap, vasculopathy, use of prolonged large bore catheters, and concomitant surgery (circumcision, distal counter-incision, urethral/neurovascular bundle mobilization). Case 1 was a patient with a history of radiation for prostate malignancy who had notably hypervascular corpora intraoperatively. On postoperative day (POD) #1, the urethral meatus was ecchymotic along with patchy ecchymosis throughout the glans. The Kerlix wrap can be seen around the penile shaft up to the corona. Removing the constrictive wrap and increasing room lighting revealed a well-vascularized glans with spotty ecchymosis likely from passage of the Keith needles during deployment. Case 2 was another patient examined on POD1 after uneventful IPP placement under local anesthesia. Note the similar level of ecchymosis involving the scrotum. Case 3 is another patient examined POD1 from a penoscrotal IPP that required multiple firing attempts with the Keith needle. Again, multifocal areas of patchy ecchymosis are interspersed with areas of normal appearing glans. The patient’s skin color was also similar in appearance to the areas of ecchymosis, requiring careful attention to detail to differentiate. Finally, Case 4 is an image on POD0 after uneventful IPP. The patient required several Keith needle passes because Furlow tool severed suture. Notably, decision was made to leave the penile implant in place in all cases. The penile wrap and/or catheter was removed and lighting was optimized to evaluate for clinical change. No patient reported paresthesia or pain out of proportion to the clinical examination. All glans were warm to the touch. Rates of glans bruising at POD3 for 298 implants performed since 2024 under local anesthesia, with bruising scored 0-4, were as follows: 0: 3.7% 1: 48.7%, 2: 25.5% 3: 21.1% 4: 0.3%. This demonstrates high rates of glans bruising with local anesthesia. We speculate that the increased rate of glans bruising may be attributed to the aggressive nature of the local anesthesia block, which can result in vasodilation and ecchymosis due to needle trauma and increased vascular permeability. Conclusions IPP cylinder deployment requiring multiple Keith needle punctures, constrictive post-op penile wrap, hypervascular corpora, exam/images with poor lighting, extensive bruising in other areas, and IPPs performed under local anesthesia appear may contribute to glans discoloration that mimics ischemia. A detailed physical exam and close clinical monitoring are essential when postoperative glans discoloration is observed. Disclosure No

Abstract Introduction Inflatable Penile Prostheses (IPPs) are a surgical implant used to treat erectile dysfunction in patients who do not respond to clinical treatments. IPP cylinder size often changes with cylinder exchange upon revision, but trends in these changes have not been formally assessed in the existing literature. Objective To analyze patient data for changes in implant size upon first revision. Methods Data included patients who underwent IPP surgical revision at Mayo Clinic Rochester between January 2021 and May 2024. Inclusion criteria specified cylinder exchange upon first revision of the IPP. A total of 48 patients were included in the analysis. A Bayesian regression was used to estimate the posterior probability of an increase in cylinder size upon first revision, after adjusting for patient age, revision service provider, and duration between implant and revision as covariates. Linear regression was used to assess the relationship between the extent of cylinder size increase and duration before revision. Results The median increase in cylinder size is 2 cm for the left cylinder and 1.75 cm for the right cylinder. The median increase for each patient’s average cylinder size is 1.625 cm. The median percentage increase in cylinder size is 9.76% for the left cylinder and 8.11% for the right cylinder. The median percentage increase for each patient’s average cylinder size is 8.13%. Posterior probabilities of increase were significant for the left cylinder, right cylinder, and the average cylinder size (Left PP: 97.53%; Right PP: 98.05%; Average PP: 98.05%). The extent of cylinder size increase is not significantly associated with duration before revision (Left p-value = 0.476; Right p-value = 0.500). Conclusions Patients and surgeons can expect about a 10% increase in cylinder size with their first revision. However, the extent of increase is not significantly associated with the duration between implant date and first revision. Future research efforts should focus on identifying where exactly this additional size is generated and what extent of size increase amounts to a noticeable difference for patients.

Abstract Introduction Proximal perforation in complex penile prosthesis placement is well recognized. If recognized, suture sling repair amongst other techniques is our favored approach. Unrecognized proximal perforation often results in unilateral or bilateral perineal bruising, often with eventual proximal device migration and palpability of the proximal device in the buttock. Objective We present a series of 5 cases in which the suture sling technique was utilized for known proximal perforation, with subsequent need for immediate or delayed revision. Methods We assessed all cases performed at Mayo Clinic since 2018 that resulted in a known suture sling complication amongst 3 high volume implanters. We identified 5 cases in which the suture sling technique required revision surgery. All patients underwent cross sectional imaging for further evaluation. Results Patients were males aged 59 to 89 with erectile dysfunction. There were no consistent factors amongst the 5 cases that may have predicted suture sling complication. The majority of cases were inflatable penile prostheses (4/5), were prosthesis revision cases (3/5), utilized the penoscrotal approach (4/5), were Coloplast devices (4/5), utilized rear tip extenders (3/5), utilized Prolene suture sling (3/5), and returned to OR within 2 days for revision (3/5). The majority of the complications (4/5) involved excessive proximal cylinder length that were palpable on examination of the buttocks or near the rectum (one felt on rectal exam). One case demonstrated improper anchoring of the device not allowing proximal seating and thus S shaped deformity. We noted medial cylinder deviation on all imaging, as corporal perforation was always medial to the true corporal path. Conclusions When performing suture slings, surgeons should be very wary of oversizing. The medial cylinder path and prior surgical capsule may mislead surgeons when choosing appropriate cylinder length. If perforated, we advocate against rear tips and for under sizing in general, as proximal anchoring is reliant upon the suture, not a true corporal boundary. Similarly, the device should be fully inflated and proximally seated on palpation prior to tying down the sling to avoid S deformities. Disclosure No

Abstract Introduction The U.S. Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization (June 2022), which overturned Roe v. Wade, has prompted significant shifts in reproductive health behavior, particularly among men. Several studies have reported trends in vasectomy-related interest and procedural volume following the decision, suggesting a growing inclination to pursue vasectomy as a long-term contraceptive option amid changing abortion access on national and statewide levels. Emerging research has also begun to explore the motivations behind this trend, pointing to a complex interplay of personal, social, and policy-related factors. However, the current body of evidence is fragmented, spanning various settings and study designs. Thus, there is a need to map the breadth and scope of this literature, identify key themes, and highlight gaps in knowledge. Objective To review the published literature assessing changes in vasectomy interest and utilization following the Dobbs decision. Methods This scoping review was conducted in accordance with established methodological frameworks to systematically map the existing literature on vasectomy trends in the United States following the Dobbs decision. A scoping review was chosen rather than a systematic review or meta-analysis due to the heterogeneity in study designs, populations, and outcome measures. Eligible studies included peer-reviewed articles examining adult patients concerning vasectomy in U.S. settings, with a focus on changes in utilization, interest, or related behaviors in response to abortion policy shifts. A comprehensive search strategy was developed to capture English-language peer-reviewed literature from 2010 onward. Searches were conducted in January 2025 across six databases: PubMed (n=207), Embase (n=243), Scopus (n=195), Web of Science (n=48), Cochrane Library (n=17), and ClinicalTrials.gov (n=0). Search terms included variations of “vasectomy” and “abortion.” Two independent reviewers screened articles and extracted data using a piloted form on the Covidence platform, collecting information on study characteristics, population demographics, outcomes related to vasectomy trends, patient motivations, and contextual policy factors. Results A total of 405 unique records were identified through the literature search, with 34 articles reviewed in full text. Seventeen studies met final inclusion criteria. Internet search analyses (29%, n=5) demonstrated increased interest in both vasectomy and tubal ligation following the Dobbs decision, with all reporting greater relative increases for “vasectomy” across short-, mid-, and long-term timeframes. Procedural trend analyses (29%, n=5) showed overall increases in vasectomy volume compared with 6-month to 5-year pre-Dobbs baselines. Six studies found that men undergoing or seeking vasectomy post-Dobbs were significantly younger. Five studies reported higher proportions of childless or fewer-child patients. Additionally, five studies identified shifts in marital or partner status, with increased rates of single, unpartnered, or nonmarried patients post-Dobbs. Geographic differences were observed across 47% of studies (n=8), with greater vasectomy and tubal ligation interest reported in states with abortion trigger laws or more restrictive abortion environments. Conclusions This scoping review identified key demographic and geographic patterns in vasectomy trends following the Dobbs decision. Findings underscore increased interest and utilization, particularly among younger, childless, and unpartnered men, and highlight regional variation aligned with abortion policy restrictiveness. These results warrant further prospective study on patient-level motivations for permanent sterilization. Disclosure No

Abstract Introduction Infection following inflatable penile prosthesis (IPP) placement is an uncommon yet serious complication, and its management poses significant clinical challenges. IPP infection management strategies continue to evolve, however, multicenter and robust studies evaluating and describing current practice patterns are lacking. Objective Using a large cohort from tertiary IPP referral centers in the United States to evaluate current infection management practice patterns and to identify factors that could predict the approach to managing IPP infections. Methods We queried a retrospective 14-center multi-institutional database for patients with IPP infections between April 2017 and January 1/2025. Patients were categorized by infection management strategy, which included device explant, malleable salvage, and 3-piece IPP salvage. Patient characteristics were compared using chi-square and independent t-tests. Multinomial analysis was performed to investigate patient and perioperative factors associated with management strategy at the time of infection. Results Among 2,934 cases, 85 (2.9%) patients developed IPP infection at a median of 40 (22-78) days after IPP implantation. Infections occurred after primary IPP surgery in 59 (69%), revision in 25 (29%), and after infection salvaged with IPP in 1 (1%). Infections were managed with device explant in 32 (38%), malleable salvage in 43 (51%), and IPP salvage in 10 (12%). A significantly higher proportion of non-White patients underwent salvage (either with malleable or IPP) compared to White patients (p=0.01). Multinomial regression showed no association between patient and perioperative characteristics and infection management (p>0.05). Conclusions In this multi-institutional cohort of experienced implanters, infections were most commonly managed with malleable salvage. Patient and perioperative factors did not predict management approach, suggesting that the decision between explanation and salvage is primarily driven by individual surgeon preference.

Abstract Introduction With the growing use of 0.05% Chlorhexidine Gluconate (CHG) as irrigation and dip for inflatable penile prosthesis (IPP) surgery, understanding the possible relationship between CHG use and non-infectious complications is imperative. Such information may guide provider decision-making during implant surgery. Objective We therefore sought to determine whether the use of 0.05% Chlorhexidine Gluconate (CHG) during inflatable penile prosthesis (IPP) surgery was associated with non-infectious wound complications. Methods We performed a multi-institutional retrospective cohort study of patients undergoing IPP surgery from January 2017 to March 2024. The primary outcome was wound complications (ex. rash, wound dehiscence, edema). Secondary outcomes included other non-infectious complications (Table 1). The primary exposure was whether patients received intraoperative CHG either as irrigation or dip. Descriptive comparisons were used to compare CHG and non-CHG cohorts. Univariable logistic regression was utilized to assess if CHG use was associated with any non-infectious complication. Multivariable logistic regression was subsequently performed to assess factors associated with certain non-infectious complications after IPP surgery – controlling for age, body mass index, race, diabetes, and hypertension as covariables. Results Across 2,933 patients, there were 1,573 non-CHG and 1,359 CHG patients. Non-infectious complications occurred in 83 (5%) non-CHG patients and in 65 (5%) CHG patients. Median follow-up was 22 months (IQR 7-59) for non-CHG patients and 8 months (IQR 3-16) for CHG patients. The incidence of wound complications was greater among CHG patients than non-CHG patients (1.0% vs. 0.1%, p<0.01). On univariable logistic regression, CHG use was associated with increased odds of wound complications (OR 7.34, 95% CI 1.65-32.71) but was not associated with any other non-infectious complication (Table 2). On multivariable logistic regression, CHG use remained associated with an increased odds of wound complications (OR 13.86, 95% CI 1.80-106.44). Conclusions Among patients experiencing non-infectious complications after IPP, CHG use during IPP surgery appears to be associated with an increased odds of wound complications.
