Perioperative Antimicrobial Strategies in Inflatable Penile Prosthesis Surgery: Associations Between Antifungals, Oral Antibiotics, and Intravenous Antibiotic Duration, and Infection Outcomes
Abstract Introduction Vacuum erectile device (VED) is 1 of the main approved therapies for erectile dysfunction (ED). The introduction of phosphodiesterase type 5 inhibitor (PDE5i) for ED significantly changed the roles of VED in contemporary sexual medicine. Objective To provide updated clinical evidence to inform health care providers on best practices with VED. Methods A consensus panel was held with leading sexual medicine experts during the 5th International Consultation on Sexual Medicine (ICSM). Relevant peer-reviewed literature was reviewed with focus on research from the last 10 years, but not limited to the last 10 years. The expert panel generated consensus statements based on the quality of evidence and criteria of Grading of Recommendations Assessment, Development and Evaluation. Results As a primary or combination therapy for ED, VED has been shown to be successful in all populations studied, including difficult to treat cohorts, such as diabetes mellitus, spinal cord injury, and post-radical prostatectomy (RP), but long-term attrition rates are high. Available evidence has shown that VED can preserve or restore penile size for patients after RP, after incision and grafting surgery for Peyronie’s disease, before and after penile prosthesis, and after other post pelvic surgeries. However, it has not demonstrated a more rapid recovery of spontaneous erectile function after RP. VED does not increase penile length for subjective short penis. Studies with female specific VED for female sexual dysfunction are very limited. Conclusions Since the prior 4th ICSM, more evidence is available to support the new roles of VED in contemporary sexual medicine. Research into the penile pathophysiologic changes with VED therapy and clinical outcomes for various conditions are ongoing. We encourage sexual medicine clinicians to follow the 5th ICSM recommendations, but providers should also use their own judgement and adopt shared decision making with their patients/partners when considering VED for a specific disorder.
(165) NOVEL INSIGHTS ON PERIOPERATIVE ANTIMICROBIAL PROPHYLAXIS PATTERNS FOR INFLATABLE PENILE PROSTHESIS: FINDINGS FROM A LARGE MULTINATIONAL COLLABORATIVE
Abstract Introduction Inflatable penile prosthesis (IPP) surgery is a well-established treatment for erectile dysfunction (ED). There is little information in the literature regarding the utilization of perioperative antimicrobial prophylaxis in primary and revision IPP surgeries. Objective We investigated the patterns of perioperative antimicrobial prophylaxis among a large multinational cohort of primary and revision IPP surgeries. Methods We conducted a retrospective analysis of 5,400 patients (4,187 primary IPP patients and 849 revision IPP patients) from our Prosthetic Urology Multi-Institutional Partnership (PUMP) institutions. Usage data for intravenous (IV), preoperative oral, and postoperative oral antimicrobials were analyzed. We specifically assessed patient profiles, antimicrobial selection, and antimicrobial duration. Multivariate statistical analyses were conducted to identify significant variations between primary and revision surgeries. Results For patients undergoing primary IPP placement, 81.9% received IV antibiotics for <24 hours whereas 18.1% received IV antibiotics for >24 hours. Preoperative oral antimicrobials were used in 59.4% of patients and 99.4% received postoperative oral antimicrobials. The overall infection rate for primary implants was 2%. Notably, quinolone administration shows a higher postoperative infection rate (11.4%) compared to gentamicin (1.9%), cephalosporin (0%), and vancomycin (1.0%). Multivariable regression analysis identifies factors such as a history of infection, diabetes, and priapism as predictors for postoperative infections. Furthermore, the study finds that perioperative antifungal use is associated with a decreased risk of infection. Conclusions This study provides valuable insights into the patterns of perioperative antimicrobial prophylaxis. Duration, type, and route of antibiotics given preoperatively or postoperatively do not affect postoperative infection rates among high volume prosthetic urologists. Giving IV antibiotics for more than 24 hours does not affect postoperative infection. Perioperative antifungals are a protective factor.

(012) USE OF REAR TIP EXTENDERS IS ASSOCIATED WITH INCREASED RISK OF POST-OPERATIVE COMPLICATIONS AND PENILE PROSTHESIS REVISION IN PATIENTS UNDERGOING PRIMARY INFLATABLE PENILE PROSTHESIS PLACEMENT: RESULTS FROM A LARGE MULTI-INSTITUTIONAL COLLABORATIVE
Abstract Introduction The utilization of rear tip extenders (RTE) is often imperative during Inflatable Penile Prosthesis (IPP) placement. The impact of RTE on perioperative morbidity of IPP surgery is underexplored. Objective In this study, we assess intraoperative and postoperative outcomes among patients undergoing primary IPP implantation with or without RTE. Methods We performed a multicenter, retrospective analysis of men undergoing primary IPP placement between July 2016 and July 2021. A total of 4308 patients were identified, of which 2963 had no RTE and 1345 had RTE. After 1:1 propensity score matching for all confounding variables, 840 patients without RTE were compared to patients with RTE for intraoperative and postoperative outcomes. Chi-square and Mann–Whitney tests were used for statistical analysis for categorial and continuous variables respectively. For multivariable analysis, we used a forward stepwise model and included significant variables found on preoperative characteristics of patients. Kaplan–Meier time to event analysis were compared with Mantel-Cox log-rank test. Results Patients with RTE use had more postoperative complications (9.6% vs 5.2%, p < 0.001). More specifically, RTE patients had more episodes of postoperative hematoma and bleeding (2.0% vs 0.7%, p = 0.033), device malfunction (2.7% vs 1.8%, p = 0.006), and glans-related complications (0.8% vs 0, p = 0.015). On multivariable analysis, use of RTE (OR 1.58, 95% CI 1.07-2.34, p = 0.021), AMS 700 series device (OR 1.93, 95% CI 1.27-2.94, p = 0.002), penoscrotal approach (OR 2.60, 95% CI 1.61-4.18, p < 0.001), and older age (OR 1.02, 95% CI 1.00-1.04, p = 0.035) were associated with increased risk of postoperative complications. Patients with RTE use had increased rate of postoperative IPP revision (5.0% vs 2.1%, p = 0.002). The use of RTE (OR 1.71, 95% CI 1.00-2.90, p = 0.046), AMS 700 series device (OR 1.73, 95% CI 1.01-2.97, p = 0.048), penoscrotal approach (OR 3.16, 95% CI 1.63-6.17, p < 0.001), and history of Peyronie’s disease (OR 2.24, 95% CI 1.31-3.82, p = 0.003) were associated with increased risk of postoperative IPP revision or explantation. On Kaplan–Meier analysis, use of RTE was associated with increased risk of postoperative complications and IPP revision or explantation within 48 months (log rank p = 0.001 and p = 0.002 respectively). Conclusions In this large multi-institutional cohort, patients with RTE experienced more hematoma, device malfunctioning, and glans related post operative complications. The use of RTE is an independent predictor of post-operative complications and IPP revision or explanation. Disclosure No.

Does climate impact inflatable penile prosthesis infection (IPP) risk? Assessment of temperature and dew point on IPP infections
Abstract Background Variations in climate have been associated with a greater risk of surgical site infections, urinary tract infections, and changes in the skin microbiome; however, limited data exist on the impact of climate on inflatable penile prosthesis (IPP) infections. Aim We sought to evaluate the impact of climate on the risk of IPP infections in a large international, multicenter cohort. Methods We performed a multi-institutional, retrospective study of patients undergoing IPP surgery. We then evaluated whether the month or season, during which surgery was performed, affected device infections. Implant infections were defined as infections requiring device explantation. A univariate logistic regression analysis was undertaken. Outcomes Our primary outcome was implant infection. Results A total of 5289 patients with a mean age of 62.2 ± 10.8 years received IPP placement. There was a fairly even distribution of implants performed in each season. A total of 103 (1.9%) infections were recorded. There were 32 (31.1%) IPP infections in patients who underwent surgery in the summer, followed by 28 (27.2%) in the winter, 26 (25.2%) in the spring, and 17 (16.5%) in the fall. No statistically significant differences were recorded in terms of season (P = .19) and month (P = .29). The mean daily temperature (P = .43), dew point (P = .43), and humidity (P = .92) at the time of IPP placement was not associated with infection. Clinical Implications These findings provide reassurance to prosthetic urologists that infection reduction strategies do not need to be tailored to local climate. Strengths and Limitations Climate data were not directly recorded for each hospital, but rather based on the monthly averages in the city where the surgery was performed. Conclusion The climate at time of IPP placement and time of year of surgery is not associated with IPP infection risk.
(103) Prior Intracavernosal Injection Therapy and Prostate Cancer Treatment are Both Independently Associated with Increased Risks of Complications in Men Undergoing Inflatable Penile Prosthesis Placement
Abstract Introduction Intracavernosal injection (ICI) therapy for erectile dysfunction (ED) carries a risk of corporal fibrosis, potentially making placement of an inflatable penile prosthesis more difficult. Prostate cancer treatment may also induce corporal fibrosis. Objective To assess whether a history of ICI or prostate cancer treatment is associated with complications following IPP placement. Methods A retrospective cohort study of primary IPP cases from 2016–2021 across 16 institutions. Patients were stratified by history of ICI and between-group differences in risk factors were assessed. Multivariable logistic regression was used to assess for predictors of intraoperative complications, postoperative non-infectious complications and postoperative infection. Results A total of 2540 patients met inclusion criteria of which 781 (30.8%) had a history of ICI. Patients with a history of ICI tended to be older (mean 63 vs 64 years, p=0.002) and were more likely to have history of radical prostatectomy (21.0% vs. 32.1%, p<0.001) and/or radiation (5.51% vs 10.9%, p<0.001). On multivariable regression, a history of ICI, prostatectomy, and radiation were all significant predictors of intraoperative complications (OR 2.11, p=0.03; OR 2.27, p=0.03; OR 2.40, p=0.04, respectively). A history of ICI and patient age were predictors of non-infectious postoperative complications (OR 1.44, p=0.02, OR 1.02, p=0.004 respectively)). None of the variables were significant predictors of infection. Conclusions In men undergoing IPP placement, a history of ICI is associated with an increased risk of both intraoperative and postoperative, non-infectious complications. Prostate cancer treatment with radiation or surgery is independently associated with increased risk of intraoperative complications.

(484) Single Dilation in Primary Inflatable Penile Prosthesis Placement is Associated with Less Corporal Complications than Sequential Dilation
Abstract Introduction In primary implant patients without significant corporal fibrosis, penile implant surgical technique varies in implementation of either single dilation (SingD) or sequential dilation (SeqD). Vigorous debate exists regarding both methods, but there is no robust evidence supporting one technique over the other in the literature. Objective We compared the rates of intraoperative complications and postoperative outcomes from a large international database of inflatable penile prostheses (IPP) performed by expert implant surgeons to determine if there were any significant differences in rates between SingD and SeqD. Methods We analyzed IPP cases performed by international implanters from 2016-2021. All primary implant cases were included, while revision cases, salvage operations, and patients with evidence of corporal fibrosis were excluded. Intraoperative complications and postoperative noninfectious outcomes were assessed between the two groups. These included proximal/distal perforation and cylinder crossover. Results After exclusion based on aforementioned criteria, we identified 3045 patients who underwent IPP. After 1:1 propensity matching of both groups, we analyzed 572 patients who underwent SingD and 572 patients who underwent SeqD. Between the two groups, more men of non-Caucasian race underwent SingD vs SeqD (p<0.001). There was a significant difference in cylinder length in the SeqD group vs the SingD group (20cm ± 1.5 vs. 20 cm ±2 respectively, p=0.018). There were 8 (0.7%) intraoperative complications in total, 7 in the SeqD group and 1 in the SingD group (p=0.034). Of these intraoperative complications, 3 (37.5%) patients who underwent SeqD sustained a proximal perforation, 3 (37.5%) sustained distal crossover, and 1 (12.5%) sustained proximal crossover. 1 patient (12.5%) with intraoperative complication who underwent SingD sustained a proximal perforation. Postoperatively, 78 (82%) of complications were in the SeqD group and 17 (18%) in the SingD group (p<0.001). Of these postoperative complications, there were 15 patients with bleeding or hematoma, of which 14 were in the SeqD group vs 1 in the SingD group (p<0.001). Of the 35 patients who were noted to have device-related malfunction, 29 underwent SeqD and 6 underwent SingD (p<0.001). Postoperative complications were more related to technical error in the SeqD vs the SingD group (11 patients and 1 patient respectively, p<0.011). On multivariate analysis, prior radical prostatectomy was predictive of intraoperative complications (OR 4.59 with IQR 1.39-15.16, p=0.024), while larger cylinder size seemed to be protective (OR 0.66 with IQR 0.50-0.89, p=0.006). On multivariate analysis, SeqD was predictive of postoperative complications (5.16 with IQR 3.01-8.83, p<0.001), as was history of priapism (4.15 with IQR 1.30-13.29, p=0.017). Patients who undergo SeqD may be calibrated by the surgeon to have more complex corpora, which could explain higher complication rates. We identified 3045 patients who underwent IPP. Conclusions In our international multicenter assessment of primary IPPs without corporal fibrosis performed by expert surgeons, patients undergoing single dilation appear to have slight benefit in total cylinder length. Sequential dilation may confer greater risk of intraoperative and postoperative complications, including bleeding and hematoma. Single dilation is a safe technique for primary inflatable penile prosthesis.

(291) Long-term Assessment of the Safety and Efficacy of the Mini-Jupette Sling: 5-year Follow-up of the Original Series
Abstract Introduction Climacturia has been reported in up to 64% of patients following radical prostatectomy (RP). In 2017, a prospective multicenter, multinational, investigational pilot study was conducted examining outcomes using a novel surgical technique, the Mini-Jupette sling, for the management of men with post-RP erectile dysfunction (ED) and climacturia and/or minimal stress urinary incontinence (SUI). We sought to report the 5-year outcomes from this original cohort. Objective To assess long-term safety and efficacy of the mini-jupette sling in the treatment of ED and concomitant mild SUI and/or climacturia Methods We identified patients who were enrolled in the previous multicenter study with post-RP ED and climacturia and/or mild SUI (2 ppd) and underwent IPP insertion with simultaneous placement of a Mini-Jupette sling. Data including current ppd, improvement in climacturia, complications, need for revision of IPP or additional urinary incontinence surgery, and date of most recent follow-up were collected. Results Of the original 38 patients, 5 have since died and 10 were lost to follow-up with 23/38 (61%) patients available for evaluation of long-term outcomes. The average follow-up time was 59 months (SD= 8.8) with a mean age of 69 years (SD= 6.8). Most patients (n=21, 91%) had subjective improvement of SUI and climacturia. One patient with persistent bothersome incontinence underwent artificial urinary sphincter (AUS) placement in 2018 with no complications, while the other is still considering a repeat procedure due to minor but persistent SUI. The mean ppd decreased from 1.4 preoperatively to 0.3 at a mean 5 years of follow-up. Most patients reported satisfaction in their urinary symptoms with 91% and 73% reporting improvement in SUI and climacturia respectively, compared to 86% and 93% respectively in the original series. One (4.3%) patient had an IPP revision for pump malfunction. There were no device infections reported. Conclusions The Mini-Jupette sling appears to be a safe and effective procedure with durable improvements in SUI and climacturia at 5 years of follow-up.
