Long-term lower urinary tract sequelae following AUS cuff erosion.

AIMS: To examine the rate of lower urinary tract complications (LUTC) and urinary diversion (UD) after artificial urinary sphincter (AUS) explantation with the acute reconstruction of AUS cuff erosion defects. METHODS: We performed a retrospective study of patients who underwent in-situ urethroplasty (ISU) for AUS cuff erosion from June 2007 to December 2020. Outcomes included LUTC (urethral stricture, diverticulum, fistula), AUS reimplantation, and UD. Defect size was prospectively estimated acutely and a subanalysis was performed to determine the impact of erosion severity (small erosions [<33% circumferential defect] and large erosions [≥33%]) on these outcomes. Kaplan-Meier curves were created to compare survival between the two groups. RESULTS: A total of 40 patients underwent ISU for urethral cuff erosion. The median patient age was 76 years old with a median erosion circumference of 46%. The overall LUTC rate was 30% (12/40) with 35% (14/40) of patients requiring permanent UD. Secondary AUS placement occurred in 24/40 (60%) patients with 11/24 (46%) leading to repeat erosion. On subanalysis, small erosion was associated with improved LUTC-free and UD-free survival but not associated with AUS reimplantation. CONCLUSIONS: Lower urinary tract complications are common after AUS cuff erosion and can lead to the need for permanent UD. Patients with larger erosions are more likely to undergo UD and reach this end-stage condition earlier compared to patients with small erosions.

Presenting signs and symptoms of artificial urinary sphincter cuff erosion.

PURPOSE: To characterize the most common presentation and clinical risk factors for artificial urinary sphincter (AUS) cuff erosion to distinguish the relative frequency of symptoms that should trigger further evaluation in these patients. MATERIALS AND METHODS: We retrospectively reviewed our tertiary center database to identify men who presented with AUS cuff erosion between 2007 - 2020. A similar cohort of men who underwent AUS placement without erosion were randomly selected from the same database for symptom comparison. Risk factors for cuff erosion - pelvic radiation, androgen deprivation therapy (ADT), high-grade prostate cancer (Gleason score ≥ 8) - were recorded for each patient. Presenting signs and symptoms of cuff erosion were grouped into three categories: obstructive symptoms, worsening incontinence, and localized scrotal inflammation (SI). RESULTS: Of 893 men who underwent AUS placement during the study interval, 61 (6.8%) sustained cuff erosion. Most erosion patients (40/61, 66%) presented with scrotal inflammatory changes including tenderness, erythema, and swelling. Fewer men reported obstructive symptoms (26/61, 43%) and worsening incontinence (21/61, 34%). Men with SI or obstructive symptoms presented significantly earlier than those with worsening incontinence (SI 14 ± 18 vs. obstructive symptoms 15 ± 16 vs. incontinence 37 ± 48 months after AUS insertion, p<0.01). Relative to the non-erosion control group (n=61), men who suffered erosion had a higher prevalence of pelvic radiation (71 vs. 49%, p=0.02). CONCLUSION: AUS cuff erosion most commonly presents as SI symptoms. Obstructive voiding symptoms and worsening incontinence are also common. Any of these symptoms should prompt further investigation of cuff erosion.

Radiographic Assessment of Inflatable Penile Prosthesis Reservoir Location Variability in Contemporary Practice.

BACKGROUND: Inflatable penile prosthesis (IPP) reservoirs are typically placed into the Space of Retzius (SOR) or alternative locations including the High Submuscular (HSM) space via transinguinal (TI) or counter incision (CI) techniques. A cadaver study showed variability in reservoir location after TI-HSM placement. AIM: To evaluate reservoir location using cross-sectional imaging following IPP insertion. METHODS: We retrospectively reviewed our institutional database and identified men who underwent virgin penoscrotal IPP insertion between 2007 and 2019. We then identified those men who subsequently underwent cross-sectional imaging prior to October 2019. Radiologists evaluated cross-sectional imaging in a blinded manner and categorized reservoir locations as follows: 1) submuscular; 2) posterior to the external oblique fascia and lateral to the rectus abdominis musculature; 3) preperitoneal; 4) retroperitoneal; 5) intraperitoneal; 6) inguinal canal; 7) subcutaneous. Patients were stratified by reservoir placement technique, transinguinal space of Retzius (TI-SOR), transinguinal high submuscular (TI-HSM), or counterincision high submuscular (CI-HSM). Clinical characteristics and outcomes were reviewed and compared. Statistical analysis was performed using Chi-squared and Fisher's exact tests. OUTCOMES: Variability exists in the TI placement of SOR and HSM reservoirs, CI-HSM reservoirs were associated with a low level of variability. RESULTS: Among 561 men who underwent virgin IPP insertion during the 12-year study period, 114 had postoperative cross-sectional imaging (29 TI-SOR, 80 TI-HSM, and 5 CI-HSM). Among the 114 patients imaged, TI-HSM reservoirs were more likely than TI-SOR to be located anterior to the transversalis fascia (48 vs 14%, P < .01) and were less likely to be located in the preperitoneal space (18 vs 62%, P < .01). Rates of intraperitoneal reservoir location were similar between the TI-HSM and TI-SOR groups (5 vs 7%, P = .66). Among imaged CI-HSM reservoirs, 4 (80%) were anterior to the transversalis fascia and 1 (20%) was within the inguinal canal. Among all 536 transinguinal cases (131 TI-SOR and 405 TI-HSM), rates of reservoir-related complications requiring operative intervention were similar between groups (5 vs 2%, P = .24). No complications were noted among the 25 patients in the CI-HSM cohort. CLINICAL IMPLICATIONS: The level of variability seen in this study did not seem to impact patient safety, complications were rare in all cohorts. STRENGTHS AND LIMITATIONS: This study is the first and largest of its kind in evaluating reservoir positioning in live patients with long-term follow-up. This study is limited in its retrospective and nonrandomized nature. CONCLUSIONS: Despite variability with both TI-HSM and TI-SOR techniques, reservoir related complications remain rare.

Most men with artificial urinary sphincter cuff erosion have low serum testosterone levels.

AIMS: To evaluate the relationship between serum testosterone (T) levels and artificial urinary sphincter (AUS) cuff erosion in a population of incontinent men who underwent AUS placement. METHODS: A retrospective analysis of our single-surgeon AUS database was performed to identify men with T levels within 24 months of AUS placement. Men were stratified into two groups based on serum testosterone: low serum testosterone (LT) (<280 ng/dl) and normal serum testosterone (NT) (>280 ng/dl). Multivariable analysis was performed to control for risk factors. The outcome of interest was the incidence of and time to spontaneous urethral cuff erosion; other risk factors for cuff erosion were also evaluated. RESULTS: Among 161 AUS patients with serum testosterone levels, 84 (52.2%) had LT (mean: 136.8 ng/dl, SD: 150.4 ng/dl) and 77 (47.8%) had NT (mean: 455.8 ng/dl, SD: 197.3 ng/dl). Cuff erosion was identified in 42 men (26.1%) at a median of 7.1 months postoperatively (interquartile range: 3.6-13.4 months), most of whom (30/42, 71.4%) were testosterone deficient. LT levels were less common (54/119, 45.4%) in the non-erosion cohort (p = 0.004). Men with low T were nearly three times as likely to suffer AUS erosion than men with normal T (odds ratio = 2.519, p = 0.021). LT level was the only factor associated with AUS erosion on multivariable analysis. CONCLUSIONS: LT is an independent risk factor for AUS cuff erosion. Men with LT are more likely to present with cuff erosion, but there is no difference in time to erosion.

State of the Reservoir: Current Concepts of Penile Implant Reservoir Placement and Potential Complications.

PURPOSE OF REVIEW: To discuss mechanical and surgical innovations in inflatable penile prosthesis (IPP) surgery and their implications on reservoir placement and patient outcomes. RECENT FINDINGS: The past decade has seen a new emphasis on optimizing outcomes and minimizing complications associated with IPP reservoirs. Innovations in device design have accordingly yielded safer, more durable IPP outcomes over the past four decades. Modifications in surgical approach for reservoir placement abound for both traditional space of Retzius and ectopic reservoir placement techniques. Surgical and medical history, patient anatomy, and patient preference should all be considered when choosing approach for IPP reservoir placement. Prosthetic urologists should be proficient in multiple approaches to provide the best care to their patients.

Artificial Urinary Sphincter Complications: Risk Factors, Workup, and Clinical Approach.

PURPOSE OF REVIEW: To review risk factors for AUS complications and present a systematic approach to their diagnosis and management. RECENT FINDINGS: Established risk factors for AUS complications include catheterization, channel TURP, pelvic radiation, urethroplasty, anticoagulation, cardiovascular disease, diabetes mellitus, frailty index, hypertension, low albumin, and low testosterone. We present our algorithm for diagnosis and management of AUS complications. Despite being the gold standard of treatment for men with SUI, major and minor complications can occur at any point after AUS insertion. Careful consideration of the urologic, medical, and operative risk factors for each patient can help prevent complications. A systematic approach to early and late complications facilitates their identification and effective management. The evaluating urologist must have a thorough understanding of potential AUS complications in order to restore quality of life in men with bothersome SUI.

Male stress urinary incontinence is often underreported.

INTRODUCTION Patient-reported pads per day use is a widely used metric in grading the severity of stress urinary incontinence and guiding surgical decision-making, particularly in mild-to-moderate cases. We sought to compare patient-reported stress urinary incontinence severity by pads per day with objective findings on standing cough test. We hypothesize that patient-reported pads per day often underestimates stress urinary incontinence severity. MATERIALS AND METHODS: We retrospectively reviewed our male stress urinary incontinence surgical database and identified 299 patients with self-reported mild-to-moderate stress urinary incontinence who were evaluated with standing cough test prior to surgical intervention between 2007 and 2019. Patients were evaluated with the Male Stress Incontinence Grading Scale for urinary leakage during a standing cough test. This test has been shown to reliably and accurately predict surgical success. Binary logistic regression analysis was used to identify parameters associated with stress urinary incontinence upgrading in a multivariable model. RESULTS: Among 299 patients with reported mild-to-moderate stress urinary incontinence, 101 (34%) were upgraded to severe stress urinary incontinence by standing cough test. Prior stress urinary incontinence surgery (OR 4.1, 95% CI 2.0-8.0, p < 0.0001) and radiation (OR 3.2, 95% CI 1.7-5.7, p < 0.0001) were significantly associated with Male Stress Incontinence Grading Scale upgrading in multivariable analysis. CONCLUSIONS: Roughly one-third of men who report mild-to-moderate stress urinary incontinence actually have severe incontinence observed on physical examination. All men being evaluated for stress urinary incontinence should undergo standing cough test to accurately grade incontinence severity and guide surgical management.

Standing cough test stratification of moderate male stress urinary incontinence.

PURPOSE: Patient-reported history of pads per day (PPD) is widely recognized as a fundamental element of decision-making for anti-incontinence procedures. We hypothesize that SUI severity is often underestimated among men with moderate SUI. We sought to compare patient history of incontinence severity versus objective in-office physical examination findings. MATERIALS AND METHODS: We retrospectively reviewed our single-surgeon male SUI surgical database from 2007-2019. We excluded patients with incomplete preoperative or postoperative data and those who reported either mild or severe SUI, thus having more straightforward surgical counseling. For men reported to have moderate SUI, we determined the frequency of upgrading SUI severity by recording the results of an in-office standing cough test (SCT) using the Male Stress Incontinence Grading Scale (MSIGS). The correlation of MSIGS with sling success rate was calculated. Failure was defined as >1 PPD usage or need for additional incontinence procedure. RESULTS: Among 233 patients with reported moderate SUI (2-3 PPD), 89 (38%) had MSIGS 3-4 on SCT, indicating severe SUI. Among patients with 2-3 PPD preoperatively, sling success rates were significantly higher for patients with MSIGS 0-2 (76/116, 64%) compared to MSIGS 3-4 (6/18, 33%) (p <0.01). CONCLUSIONS: Many men with self-reported history of moderate SUI actually present severe SUI observed on SCT. The SCT is a useful tool to stratify moderate SUI patients to more accurately predict sling success.

Artificial Urinary Sphincter Cuff Erosion Heat Map Shows Similar Anatomical Characteristics for Transcorporal and Standard Approach.

PURPOSE: We describe and compare artificial urinary sphincter cuff erosion sites and associated clinical implications. MATERIALS AND METHODS: We retrospectively reviewed men who presented with artificial urinary sphincter erosion treated by a single surgeon between 2007 and 2019 at a tertiary medical center. Transcorporal indications included complications of prior anti-incontinence procedures and prior urethral reconstruction. Location of artificial urinary sphincter cuff erosion defects was assessed by cystoscopy prior to device explantation, and findings were stratified into patients who had transcorporal vs standard artificial urinary sphincter placement. RESULTS: Out of 723 artificial urinary sphincter cases in 611 patients we identified 54 (7.5%) cuff erosions. Erosion developed in 15 of 82 (18.3%) cases of transcorporal artificial urinary sphincter and 39 of 641 (6.1%) cases of standard artificial urinary sphincter (p <0.05). Artificial urinary sphincter cuff erosions occurred predominantly ventrally in both groups (66.7% for transcorporal and 79.5% for standard artificial urinary sphincter, p=0.4) followed by lateral urethral location (33.3% transcorporal and 20.5% standard, p=0.3). Dorsal erosions were rare in both groups (20% transcorporal and 5.1% standard, p=0.1). History of artificial urinary sphincter and previous erosion were associated with transcorporal artificial urinary sphincter erosion. History of radiotherapy, prior urethroplasty, hypogonadism and urethral cuff size were similar between groups. CONCLUSIONS: Artificial urinary sphincter cuff erosions appear to occur ventrally and laterally in most patients regardless of cuff placement. Dorsal erosions were the least common in both groups. The protective effect of transcorporal artificial urinary sphincter could not be conclusively demonstrated.

Avoiding deep pelvic complications using a 'Five-Step' technique for high submuscular placement of inflatable penile prosthesis reservoirs.

OBJECTIVES: To compare our extended experience with high submuscular (HSM) reservoir placement to traditional space of Retzius (SOR) placement and to present our current, refined 'Five-Step' technique (FST) for HSM placement. PATIENTS AND METHODS: Data were retrospectively collected on patients undergoing inflatable penile prosthesis (IPP) placement between January 2009 and June 2019. Re-operative cases were excluded. Reservoir-related complications and subsequent revisions were compared between SOR (2009-2012) and HSM reservoir groups (2012-2019). HSM patients were subdivided into two cohorts: 'Initial Technique' (2012-2014) and FST (2014-2019). The refined FST protocol was developed in 2014 to optimise outcomes and includes the following steps: (i) Position and Access; (ii) Develop Lower HSM Pocket; (iii) Develop Upper HSM Pocket; (iv) Reservoir Delivery (fill and fine-tune); (v) Confirm and Connect. RESULTS: Between January 2009 and June 2019, 733 total IPP procedures (586 HSM, 147 SOR) were performed by a single surgeon at our institution, 561 of which were virgin cases (430 HSM, 131 SOR) and included in this analysis. Overall, surgical revision was required in 10/430 (2.3%) HSM cases (one delayed bowel obstruction, nine herniations) and six of 131 (4.6%) SOR cases (one bladder erosion, two vascular injuries, and three herniations, P = 0.22). When comparing the FST to the Initial Technique, we noted a significant decrease in complications requiring surgical revision (P = 0.01). Among 133 cases performed with the Initial Technique, seven (5.3%) required surgical revision (one bowel obstruction after placement into the peritoneal cavity, six herniations). Among 297 FST cases, three (1.0%) required revision, all due to herniation. CONCLUSION: HSM placement of IPP reservoirs is a safe alternative to traditional SOR placement. Major deep pelvic reservoir complications were minimised using our current refined FST.

Favourable multi-institutional experience with penoscrotal decompression for prolonged ischaemic priapism.

OBJECTIVES: To report our multi-institutional experience using penoscrotal decompression (PSD) for the surgical treatment of prolonged ischaemic priapism (PIP). MATERIALS AND METHODS: We retrospectively reviewed clinical records for patients with PIP treated with PSD between 2017 and 2020. Priapisms were confirmed as ischaemic based on clinical presentations and cavernosal blood gas abnormalities. Treatment with irrigation and injection of α-agonists in all patients had failed prior to PSD. Patient characteristics, peri-operative variables and outcomes, and changes in International Index of Erectile Function (IIEF) scores were evaluated. RESULTS: We analysed 25 patients who underwent a total of 27 PSD procedures. The mean duration of priapism at initial presentation was 71.0 h. Irrigations and injections in all patients had failed, while corporoglanular shunt treatment in 48.0% of patients (12/25) had also failed prior to PSD. Of the 10 patients who underwent unilateral PSD, two (20.0%) had priapism recurrence. Both were treated with bilateral PSD, with prompt and lasting detumescence. Among the 15 patients undergoing primary bilateral PSD, none had priapism recurrence. Of the 15 patients with documented sexual function status at last follow-up, nine (60%) reported spontaneous erectile function adequate for penetration, while six (40%) reported erectile dysfunction. The median (interquartile range) decrease in IIEF-5 score was 3.5 (0-6.75) points after PSD. Two patients underwent uneventful inflatable penile prosthesis placement following PSD. CONCLUSIONS: Penoscrotal decompression presents a simple, safe, highly effective and easily reproducible procedure for resolution of PIP. PSD should be considered as a viable salvage or alternative strategy to corporoglanular shunt procedures.

Explantation of High Submuscular Reservoirs: Safety and Practical Considerations.

BACKGROUND: Over the past decade, high submuscular (HSM) placement of inflatable penile prosthesis (IPP) reservoirs has emerged as a viable alternative to space of Retzius (SOR) placement; however, data comparing the feasibility and complications of HSM vs SOR reservoir removal do not presently exist. AIM: To present a comparison of the safety, feasibility, and ease of removal of HSM vs SOR reservoirs in a tertiary care, university-based, high-volume prosthetic urology practice. METHODS: Data were retrospectively collected on patients who underwent IPP reservoir removal between January 2011 and June 2020. Cases were separated into 2 cohorts based on reservoir location. Statistical analysis was performed using Fisher's exact and Chi-squared tests for categorical variables and Student's t-test for continuous variables. Timing from IPP insertion to explant was compared between the HSM and SOR groups using the Mann-Whitney U test. OUTCOMES: Time from IPP insertion to explant, operative time, intraoperative and postoperative complications, and need for a counter incision were compared between the HSM and SOR groups. RESULTS: Between January 2011 and June 2020, 106 (73 HSM, 33 SOR) patients underwent IPP removal or replacement by a single surgeon at our institution. Average time from IPP insertion to removal was 43.6 months (24.2 HSM, 52.7 SOR, P = .07)-reservoir removal occurred at the time of device explant in 70 of 106 (66%) cases. More HSM reservoirs were explanted at the time of IPP removal compared with the SOR cohort (54 of 73, 74% HSM vs 16 of 33, 48.5% SOR, P = .01). Similar rates of complications were noted between the HSM and SOR groups (1.9% vs 6.3%, P = .35). There was no significant difference in need for counter incision between the 2 groups (24 [42%] HSM vs 4 [25%] SOR, P = .16) or in average operative times (76.5 ± 38.3 minutes HSM vs 68.1 ± 34.3 minutes SOR, P = .52). CLINICAL IMPLICATIONS: Our experience with explanting HSM reservoirs supports the safety and ease of their removal. STRENGTHS AND LIMITATIONS: Although the absolute cohort size is relatively low, this study reflects one of the largest single-institution experiences examining penile implant reservoir removal. In addition, reservoir location was not randomized but was instead determined by which patients presented with complications necessitating reservoir removal during the study period. CONCLUSIONS: HSM reservoir removal has comparable perioperative complication rates and operative times when compared with SOR reservoir removal. Kavoussi M, Bhanvadia RR, VanDyke ME, et al.

Reservoir Placement Considerations During Inflatable Penile Prosthesis Surgery.

PURPOSE OF REVIEW: To discuss emerging alternative strategies for reservoir placement during inflatable penile prosthesis surgery. RECENT FINDINGS: Innovations in penile prosthesis design have facilitated the development of various alternative approaches for reservoir placement. Avoiding the space of Retzius is particularly appealing in patients with a history of pelvic surgery and/or radiation. The high submuscular technique utilizes a low-profile reservoir in combination with the implant's lockout valve to allow for safe placement in the potential space between the anterior abdominal wall musculature and the transversalis fascia, far cephalad from the external inguinal ring and without the need for a counter-incision. Multiple recent publications have demonstrated the safety and efficacy of the high submuscular technique. High submuscular inflatable penile prosthesis reservoir placement is a safe and effective alternative to placement within the space of Retzius.

Epidemiology of Genitourinary Injuries among Male U.S. Service Members Deployed to Iraq and Afghanistan: Early Findings from the Trauma Outcomes and Urogenital Health (TOUGH) Project.

PURPOSE: In this study we report the number, nature and severity of genitourinary injuries among male U.S. service members deployed to Operations Iraqi Freedom and Enduring Freedom. MATERIALS AND METHODS: This retrospective cross-sectional study of the Department of Defense Trauma Registry used ICD-9-CM codes to identify service members with genitourinary injuries, and used Abbreviated Injury Scale codes to determine injury severity, genitourinary organs injured and comorbid injuries. RESULTS: From October 2001 to August 2013, 1,367 male U.S. service members sustained 1 or more genitourinary injuries. The majority of injuries involved the external genitalia (1,000, 73.2%), including the scrotum (760, 55.6%), testes (451, 33.0%), penis (423, 31%) and/or urethra (125, 9.1%). Overall more than a third of service members with genitourinary injury sustained at least 1 severe genitourinary injury (502, 36.7%). Loss of 1 or both testes was documented in 146 men, including 129 (9.4%) unilateral orchiectomies and 17 (1.2%) bilateral orchiectomies. Common comorbid injuries included traumatic brain injury (549, 40.2%), pelvic fracture (341, 25.0%), colorectal injury (297, 21.7%) and lower extremity amputations (387, 28.7%). CONCLUSIONS: An unprecedented number of U.S. service members sustained genitourinary injury while deployed to Operation Iraqi Freedom/Operation Enduring Freedom. Further study is needed to describe the long-term impact of genitourinary injury and determine the potential need for novel treatments to improve sexual, urinary and/or reproductive function among service members with severe genital injury.

Non-erosive urethral perforation between tandem artificial urinary sphincter cuffs.

Tandem cuff artificial urinary sphincter (AUS) is a well-accepted treatment modality for refractory urinary incontinence following prostatectomy. We present a unique case of a 60-year-old male who experienced spontaneous urethral perforation between tandem AUS cuffs following a strong valsalva maneuver. The patient was treated with immediate AUS explant and transcorporal single cuff placement several months later.

Poor quality of life in patients with urethral stricture treated with intermittent self-dilation.

PURPOSE: We assessed patient perceptions of regular intermittent self-dilation in men with urethral stricture. MATERIALS AND METHODS: We constructed and distributed a visual analog questionnaire to evaluate intermittent self-dilation via catheterization by men referred for urethral stricture management at a total of 4 institutions. Items assessed included patient duration, frequency, difficulty and pain associated with intermittent self-dilation as well as interference of intermittent self-dilation with daily activity. The primary outcome was patient perceived quality of life. Multivariate analysis was performed to assess factors that affected this outcome. RESULTS: Included in the study were 85 patients with a median age of 68 years, a median of 3.0 years on intermittent self-dilation and a median frequency of 1 dilation per day. On a 1 to 10 scale the median intermittent self-dilation difficulty was 5.0 ± 2.7, the median pain score was 3.0 ± 2.7 and median interference with daily life was 2.0 ± 1.3. Overall quality of life in patients with stricture was poor (median score 7.0 ± 2.6 with poor quality of life defined as 7 or greater). On univariate analysis younger age (p <0.01), interference (p = 0.03), pain (p <0.01) and difficulty performing intermittent self-dilation (p = 0.03) correlated with poor quality of life in a statistically significant manner. On multivariate analysis only difficulty catheterizing (p <0.01) and younger age (p = 0.05) were statistically significant predictors. Patients with stricture involving the posterior urethra had a statistically significant increase in difficulty and decrease in quality of life (each p = 0.04). CONCLUSIONS: Most patients with urethral stricture who are on intermittent self-dilation rate difficulty and pain as moderate, and inconvenience as low but report poor quality of life.

Decreasing need for artificial urinary sphincter revision surgery by precise cuff sizing in men with spongiosal atrophy.

PURPOSE: Many patients with persistent incontinence after an artificial urinary sphincter procedure gain improved continence after cuff downsizing. In 2010 a new, smaller (3.5 cm) artificial urinary sphincter cuff was introduced. We hypothesized that men with spongiosal atrophy previously treated with a 4.0 cm cuff would now show a decreased rate of revision surgery due to more accurate cuff sizing. MATERIALS AND METHODS: We evaluated the outcome in men who received identical 4.0 cm cuff sizes in 2 eras, before (2007 to 2009) and after (2010 to 2013) the introduction of the 3.5 cm artificial urinary sphincter cuff. Patients with a history of cuff erosion or those undergoing tandem, transcorporal, or 4.5 cm or greater cuff placement were excluded from analysis. We validated our institutional results using the nationwide AMS® PIF (Patient Information Form) database from identical time frames. RESULTS: Of 236 men who underwent artificial urinary sphincter placement at our institution during the study period 170 with a mean age of 67 years met study inclusion criteria, of whom 88 (52%) received a 4.0 cm artificial urinary sphincter cuff. Mean followup was 34 months. Ten of 45 patients (22.2%) who had a 4.0 cm cuff placed from 2007 to 2009 required cuff downsizing for persistent incontinence while only 2 of 43 (4.7%) who received a 4.0 cm cuff from 2010 to 2013 required revision (p <0.001). Nationally patients with a 4.0 cm cuff underwent fewer revisions during the latter era (16.2% vs 7.5%, p = 0.001). In local and national cohorts Kaplan-Meier analysis revealed improved survival of the 4.0 cm cuff after the introduction of the 3.5 cm cuff (p <0.05). CONCLUSIONS: The incidence of artificial urinary sphincter revision surgery in patients with a 4.0 cm cuff has decreased since the availability of the 3.5 cm cuff. This suggests that precise cuff sizing appears to be beneficial in men with spongiosal atrophy.
