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 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 Benign prostatic hyperplasia (BPH) is an age-related condition affecting many men. Emerging evidence highlights a strong relationship between BPH, lower urinary tract symptoms (LUTS) and sexual dysfunction, including erectile dysfunction (ED), reduced sexual desire, hormonal imbalances, and ejaculatory dysfunction, warranting a comprehensive approach to diagnosis and management. Objectives This report aims to provide recommendations for identifying and managing sexual dysfunction associated with BPH and LUTS. Methods Based on guidelines from the International Consultation on Sexual Medicine, a literature review was conducted. Recommendations were graded using the Grading of Recommendations Assessment, Development and Evaluation system. Results The association between BPH, LUTS, and sexual dysfunction is significant, with ED, ejaculatory dysfunction, and hypogonadism being common complications. Lifestyle modifications, medical therapies, minimally invasive surgical therapies, prostate artery embolization, and surgeries (eg, Transurethral resection of the prostate, HoLEP, Aquablation) are among the recommended treatments. Each intervention carries varying risks of sexual dysfunction, requiring specific tailored treatment plans. Conclusions BPH/LUTS significantly affect sexual health, emphasizing the need for a multidisciplinary approach to management. Future research should refine diagnostic criteria and develop treatments that minimize sexual side effects. Enhanced education for patients and their partners could improve quality of life and coping mechanisms.

Objectives To evaluate the pre‐ and intraoperative variables that impact the integrity of the corporal bodies over time after inflatable penile prosthesis (IPP) placement, as predictors of intraoperative corporal perforation and delayed cylinder complications have not been well characterized. Patients and Methods We retrospectively reviewed a 16‐centre multi‐institutional database of IPP surgeries performed by experienced implanters from 2016 to 2021. Poor corporal integrity (PCI) was defined as intraoperative (iPCI) corporal complications or postoperative (pPCI) corporal complications. Multivariable analysis was performed to identify independent predictors of PCI, iPCI, and pPCI. Primary outcomes included intra‐ and postoperative corporal complications. Results We identified 5153 patients for analysis from 5406 IPP cases, finding 152 (2.95%) cases of PCI. On multivariable analysis, predictors of PCI included revision IPP surgery (odds ratio [OR] 8.16, 95% confidence interval [CI] 5.15–12.92; P < 0.001), sequential dilatation (OR 2.12, 95% CI 1.32–3.39; P = 0.002), coronary artery disease (CAD)/peripheral vascular disease (PVD) (OR 1.81, 95% CI 1.18–2.77; P = 0.006), older age (OR 1.02, 95% CI 1.01–1.04; P = 0.013), and corporal scarring (OR 1.58, 95% CI 1.0–2.5; P = 0.049). Predictors of iPCI included revision IPP surgery (OR 7.34, 95% CI 4.18–12.88; P < 0.001), corporal scarring (OR 2.77, 95% CI 1.64–4.69; P < 0.001), radiation therapy (OR 2.25, 95% CI 1.0–5.04; P = 0.049), and older age (OR 1.03, 95% CI 1.0–1.05; P = 0.025). Revision IPP surgery (OR 7.92, 95% CI 3.69–17.01; P < 0.001), sequential dilatation (OR 3.4, 95% CI 1.61–7.19; P = 0.001), CAD/PVD (OR 2.98, 95% CI 1.56–5.72; P = 0.001), and history of priapism (OR 3.59, 95% CI 1.08–11.99; P = 0.038) were predictive of pPCI. Conclusion Coronary artery disease/PVD, being of older age, having corporal scarring, undergoing IPP revision surgery and sequential dilatation were predictive risk factors for complications associated with PCI. Identifying patients who are at risk of having PCI may improve patient‐specific counselling, consideration of referral to more experienced implanters, and surgical planning to potentially promote longer‐term device viability.

AbstractBackgroundMicrodenervation 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 prefer stripping of the vas deferens to preserve the vasal artery, hence preserving vasculature to the testis and possibly decreasing post‐operative congestion pain.ObjectiveTo compare outcomes of patients with chronic orchialgia, who underwent MSCD by either stripping or ligating the vas deferens.Materials and methodsA retrospective chart review of 85 patients who underwent MSCD from 2017–2023 was performed. Patients’ demographics including history of prior surgical procedures were recorded. Response to surgery was evaluated as either complete resolution of pain, partial resolution of pain, or no improvement in pain.ResultsEighty‐five patients underwent MSCD with a median (interquartile range, IQR) age of 36 (25.5–46.5) years and median duration of pain of 16 (6–31) months. Thirty‐seven patients underwent stripping of vas, while 48 underwent ligation of vas during MSCD. Median follow up was 12 months. Twenty‐one (43.5%) patients had prior inguinal scrotal surgery in the 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 two groups was similar, 67.6% of patients who underwent stripping had complete resolution of pain versus 66.7% of those who had ligation (p = 0.968), with similar rates of post‐operative complications (p‐value = 0.132).ConclusionsIn men with intractable chronic scrotal content pain with no interest in preserving fertility, ligation, or stripping of the vas deferens yields similar outcomes with regard to pain resolution. Both techniques are safe with no reports of any testicular atrophy.
