Abstract Introduction Down-sized inflatable penile prosthesis (IPP) cylinders are useful in cases with substantial penile fibrosis such as history of priapism or prior infection. Although down-sized IPP cylinders have a clear role in fibrotic corpora, their role in primary implant cases is unclear. Objective To identify factors associated with the use of down-sized cylinders in men undergoing primary IPP placement. Methods We conducted a retrospective analysis of 4,389 patients undergoing primary IPP placement from our multicenter database. Patients were categorized by down-sized (AMS 700 CXR, Coloplast NB) vs. standard sized cylinders (AMS 700 CX, AMS 700 LGX, Coloplast Titan). We collected demographic, intraoperative, and postoperative data. A multivariable analysis was performed to identify factors associated with use of down-sized cylinders Results A total of 4,389 men undergoing primary inflatable penile prosthesis (IPP) placement were included in the study, with a mean age of 62.3 ± 10.3 years. Among them, 1,485 (34%) had diabetes and 2,131 (49%) had hypertension. A total of 406 down-sized cylinders and 3,983 standard cylinders were implanted. Non-infectious complications occurred more frequently with the use of down-sized cylinders (odds ratio [OR] = 2.0, p < 0.001). Specifically, non-infectious complications were reported in 44 out of 185 men (23.8%) with down-sized cylinders, compared to 192 out of 2,727 men (10.9%) with standard cylinders. Cylinder complications constituted 13.9% and 13.0% of the non-infectious complications in the down-sized and standard cylinder groups, respectively. Conclusions The rate of cylinder-related complications were similar between the down-sized cylinder and standard cylinder groups. Urologists should be prepared to place down-sized cylinders during IPP placement in diabetic men and in men requiring serial dilation due to fibrosis.

Abstract Introduction Obesity, defined as an elevated Body Mass Index (BMI) >30, is a prevalent public health concern with far-reaching implications for various medical procedures and outcomes. In the context of inflatable penile prosthesis placement (IPP), where patient well-being and surgical success are of paramount importance, the impact of obesity on postoperative and intraoperative complications warrants thorough investigation. Objective Our study aimed to investigate the impact of BMI on both postoperative and intraoperative complications in an international, multi-institutional cohort of patients who underwent IPP placement. Methods We performed a retrospective chart review of 4398 cases. These cases were divided into two distinct groups based on BMI: less than 30 (n = 2260) and greater than or equal to 30 (n = 2138). The study assessed various surgical factors as well as complications, including overall complications, corporal scarring, incontinence, intraoperative complications, proximal perforation, distal perforation, proximal crossover, distal crossover, and urethral injury. Results Our analysis revealed that there were no statistically significant differences in intraoperative or postoperative complications between the two BMI categories. Notably, proximal corporal measurement was significantly higher for >30 BMI group (9.55 +/−2.18) compared to <30 BMI group (9.14 +/−2.19), (p = < 0.001). The incidence rates for overall complications (30.2% vs. 28.7%; p = 0.164), corporal scarring (18.2% vs. 16.7%; p = 0.36), incontinence (3.53% vs. 3.13%; p = 0.076), intraoperative complications (1.94% vs. 1.68%; p = 0.253), and specific complications all exhibited no significant differences. Similarly, post-operative complications, including both non- infectious (6.99% vs. 6.22%; p = 0.215) and infectious (2.61% vs. 1.87%; p = 0.165) complications, did not significantly vary between BMI categories. Conclusions Our findings indicate that BMI does not exert a statistically significant influence on postoperative and intraoperative complications in the context of high-volume prosthetic urology. In the absence of any other differences between patients of differing BMIs, surgeons may need to be mindful of pump tubing length concerns in obese patients.

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.

Abstract Introduction Penile prosthesis (PP) is one of the main approved therapies for erectile dysfunction (ED). Greater than 50 years of clinical use has led to considerable innovation in PP surgery and patient care. Objectives To summarize the current literature and provide updated clinical evidence to inform healthcare providers on best practices with PP. 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 but not limited to the last 10 years. The quality of each individual study was judged with Oxford levels of evidence (LOE) criteria, but overall LOE were not used as systematic review was not performed. The expert panel generated consensus statements based on the quality of evidence and criteria of GRADE (Grading of Recommendations Assessment, Development and Evaluation). Results PP provides excellent outcomes for the treatment of ED. The panel developed 35 recommendations building upon previous recommendations. Nine recommendations (4, 5, 11,13,17, 25, 26, 31, and 32) are retained without change from 2015. Twelve recommendations (1, 2, 3, 7, 9,14,16,19,21, 28, 33, and 34) change syntax to make statements more active or change details. Fourteen recommendations (6, 8, 10, 12, 15, 18, 20, 22, 23, 24, 27, 29, 30, and 35) are novel in this update. Conclusion Since the 4th ICSM, new evidence has emerged to guide PP use in modern sexual medicine. While multi-institutional studies are needed to improve outcomes, key challenges remain: reducing infections, enhancing devices, and improving awareness and accessibility. We recommend following 5th ICSM guidelines while emphasizing the importance of clinical judgment and shared decision-making for optimal PP outcomes.

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.
