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.

Abstract Introduction Microdenervation of the spermatic cord (MSCD) is an effective treatment modality for men with intractable scrotal content pain. For patients not interested in preserving fertility, some centers advocate ligation of the vas during denervation while others perfer stripping of the Vas deferens to preserve the vasal artery, hence preserving vasculature to testis and possibly decreasing post operative congestion pain. Objective This multicenter study analyzes outcomes of patients that underwent MSCD by either stripping or ligating the vas deferens. Methods A retrospective chart review of 85 patients who underwent MSCD from 2020–2023 was performed. Patients’ demographics including history of prior surgical procedures was recorded. Response to surgery was evaluated as either complete resolution of pain, partial resolution of pain or no improvement in pain. Results 85 patients underwent MSCD with a median (IQR) age of 36 (25.5–46.5) years and median duration of pain of 16 months. 37 patients underwent stripping of vas while 48 underwent ligation of vas during MSCD. Median follow up was 12 months. 21(43.5%) patients had prior inguinal scrotal surgery in ligation group compared to 5 (13.5%) in the stripping group p=0.003. The etiology of pain was similar between the groups. The response to MSCD between the 2 groups was similar (p=0.968), with similar post op complications (Table 1). Conclusions In men with intractable chronic scrotal content with no interest in preserving fertility, ligation or stripping of the vas deferens yields similar outcomes with regards to pain resolution. Both techniques are safe with no reports of any testicular atrophy.

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.

Abstract Purpose The purpose of this white paper is to educate health care professionals about the evolution of telemedicine (TM) and to propose a hybrid model that leverages the strengths of traditional in-person medicine as well as virtual medicine while maximizing the safety and quality of men’s sexual health care. Literature Search Strategy A literature search focused on the use of TM in urology and men’s health was performed through PubMed/MEDLINE, Embase, and Web of Science (January 1, 2012–April 26, 2022). Keywords included all known permutations of the terminology used to refer to virtual health, care as well as the terminology used to refer to urologic diseases, issues specific to men’s health, and men’s sexual health concerns. Publications that emerged after the literature search that met this criterion also were incorporated. Opinion pieces, letters to the editor, meeting abstracts, and conference proceedings were excluded. Additional resources were retrieved, such as governmental technical reports, legislative updates and reviews, and blogs. This search strategy yielded 1684 records across databases after removal of duplicates. Abstracts from the retrieved records were reviewed for relevance. Relevant publications were defined as those that reported data on any aspect of TM use specific to urology, men’s health, and/or men’s sexual health. If relevance was unclear from the abstract, then the full text of the article was retrieved for a more detailed review. In addition, the published evidence-based practice guidelines relevant to care for erectile dysfunction, Peyronie’s disease, ejaculatory dysfunction, and hypogonadism were retrieved. The most common reasons for article exclusions were a focus on TM use in disciplines other than urology and the absence of data (ie, opinion pieces). After exclusions, a total of 91 publications remained and constituted the evidence base for this paper.

Abstract Introduction Inflatable penile prosthesis (IPP) placement is associated with high postoperative patient satisfaction. Patients often express concerns about postoperative penile length. There is scant evidence in the literature of clinical and surgical factors that predict IPP length. Objective To evaluate predictors of cylinder length for men undergoing primary IPP placement in a large multicenter cohort. Methods Patients undergoing primary IPP placement for treatment of erectile dysfunction at 16 high-volume implant centers were included. All patients had preoperative demographics, surgical characteristics, and device length retrospectively collected at their respective institutions and combined for analysis. Descriptive statistics were reported for the full group. Univariate analysis was utilized to isolate variables significantly associated with device length and all variables reaching p<0.1 were included in linear regression modeling. Results 3,953 men underwent primary IPP placement. The mean age was 61.8±10.4 years and BMI was 29.8±4.2 kg/m2. The mean total device length was 20.6±2.1cm. 1291 (32.7%) had diabetes mellitus, 641 (16.2%) were smokers, 705 (17.8%) had a prior radical prostatectomy, 195 (4.9%) had prior radiation, 549 (13.9%) had Peyronie’s disease, and 884 (22.4%) had a history of intracavernosal injections. In univariate analysis, BMI (B=0.05, 95%CI 0.04 to 0.07, p<0.001), a history of Peyronie’s disease (20.4 vs 20.6cm, p=0.02), and use of intracavernosal injection (20.7 v 20.9cm, p=0.02) were predictors of shorter total device length. Use of rear tip extenders (20.7 v 20.0cm, p<0.001), penoscrotal approach (21.0 v 20.3, p<0.001), and single corporal dilation (20.8 v 20.4cm, p<0.001) were associated with longer length. In multivariable analysis, a history of Peyronie’s disease (B=-0.29, 95%CI -0.47 to -0.11, p=0.002) and greater BMI (B=0.05, 95%CI 0.03 to 0.07, p<0.001) were predictors of shorter total device length. Independent predictors of longer device length were penoscrotal approach (B=-0.85, 95%CI -1.03 to -0.65, p<0.001), rear tip extender use (B=1.00, 95%CI 0.84 to 1.17, p<0.001), and single corporal dilation (B=-0.5, 95%CI -0.67 to -0.34, p<0.001). Conclusions In this series, Peyronie’s disease and greater BMI are independent predictors of shorter IPP device length, while use of rear tip extenders, single corporal dilation, and penoscrotal approach are independent predictors of longer device length. These results are important in counseling patients regarding expectations of postoperative length.

Abstract Introduction Predictors of intraoperative corporal perforation and delayed cylinder complications in inflatable penile prosthesis (IPP) placement have not been well-delineated in the literature. Inflatable penile prosthesis (IPP) can offer high satisfaction rates of patients, but this procedure is not without complications that can be encountered intraoperatively and postoperatively. Particularly, predictors of intraoperative corporal perforation and delayed cylinder complications in IPP placement have not been well-delineated in the literature. Objective We evaluated our retrospective multi-institutional database of IPP surgeries performed by expert implant surgeons to identify risk factors that are predictive of the development of these non-infectious complications. Methods IPP cases performed by sixteen international implanters from 2016-2021 were identified. All primary and revision cases were included. Salvage cases for infection were excluded. Demographic characteristics, intraoperative variables, and postoperative outcomes were assessed. Poor corporal integrity (PCI) was defined as intraoperative corporal complications (proximal and/or distal perforation of the corpora, corporal crossover) or postoperative corporal complications (cylinder erosion, extrusion, impending erosion, or deformity). Risk factor analysis and multivariate analysis were performed to identify predictors of PCI. Results A total of 5406 IPP cases across 16 separate institutions were assessed. There were 163 (3.0%, mean age 64) cases of PCI. Of the 156 complications that occurred, 101 (64.7%) occurred intraoperatively, while 55 (35.3%) occurred postoperatively. The rates of diabetes (p=0.669), vascular disease (p=0.054), and history of intracavernosal injections (p=0.111) all had no statistically significant effect on corporal integrity. Patients with PCI tended to have hypertension (p=0.045), current smoking (p=0.03), history of IPP infection (p<0.001), and history of shunt for priapism (p<0.001). On multivariate analysis, predictors of PCI include hypertension (OR 1.64 (1.09-2.47), p=0.018), history of IPP infection (OR 4.41 (2.52-7.84), p<0.001), and age (OR 1.02 (1.00-1.04), p=0.027). Obesity was found to be protective (OR 0.63 (0.42-0.95), p=0.027). Conclusions Our multicenter analysis found that hypertension, current smoking, history of IPP infection and age were risk factors for complications associated with poor corporal integrity. Recognizing these risk factors preoperatively can allow for improved patient-specific counseling and changes in surgical strategy to potentially prevent these complications.

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.

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.

Abstract Introduction The American Urological Association (AUA) recommendations on antibiotic prophylaxis in penile implant surgery are based on low quality evidence and expert opinion. Recent evidence suggests the recommended regimens may be suboptimal. Objective To determine if the AUA recommended antibiotic regimen (vancomycin + gentamicin) for primary penile implant surgery is associated with a higher infection risk than non-standard regimens. Methods We performed a multicenter, retrospective cohort study of patients undergoing primary IPP surgery. Patients undergoing revision surgery or with a history of IPP placement were excluded. Additionally, patients who underwent concomitant procedures for Peyronie’s disease or stress urinary incontinence were excluded. Patients were divided into those receiving standard AUA antibiotic prophylaxis (vancomycin + gentamicin) and those receiving any other (non-standard) antibiotic prophylaxis. The time to postoperative device explanation due to infection via a Cox regression model, the microorganisms involved, and the management of patients with device infection were evaluated. A subgroup analysis to identify the appropriate dosage of gentamicin was also performed. Results 4,161 patients underwent primary IPP placement (2,411 received vancomycin + gentamicin and 1,750 received other regimens). The infection rate was similar between groups, 1.0 vs 1.2% for standard vs non-standard prophylaxis. In the multivariate Cox regression analysis, the use of vancomycin + gentamicin (HR: 2.74, 95%CI: 1.38-5.41, p=0.004) and diabetes (HR: 1.87, 95%CI: 1.03-3.39, p=0.04) were significantly associated with higher risk of device explantation due to infection. Concomitant infusion of antifungals (HR: 0.08, 95%CI: 0.03-0.19, p<0.001) was associated with lower risk of infection. Staphylococcus aureus and Escherichia coli were the most frequently cultured microorganisms. Device infection was most commonly managed with salvage using a malleable prosthesis (40.4%). In patients of both groups receiving gentamicin as part of perioperative antibiotic prophylaxis, the use of weight-based gentamicin compared to 80 mg gentamicin was associated with similar risk of device explantation due to infection (HR: 2.88, 95% CI: 0.83 to 10, p = 0.1). Conclusions Vancomycin + gentamicin for antibiotic prophylaxis in primary penile implant surgery is independently associated with a higher infection risk than non-standard antibiotic regimens while antifungal use is associated with lower infection risk. There does not appear to be a difference in weight-based vs low dose (80mg) gentamicin on infection risk. Our results further demonstrate the importance of antifungal use in prophylaxis regimens. Additionally, a critical review of the recommended prophylactic regimens is needed. Tailoring individual regimens to local antibiograms may provide the best infection prevention.
