Urethral Stricture Formation Following Cuff Erosion of AMS Artificial Urinary Sphincter Devices: Implication for a Less Invasive Explantation Approach
2022
ObjectivesThe objective of this study is to describe a standardized less invasive approach in patients with artificial urinary sphincter (AUS) explantation due to cuff erosion and analyze success and urethral stricture rates out of a prospective database. Evidence regarding complication management is sparse with heterogenous results revealing high risk of urethral stricture formation despite simultaneous urethroplasty in case of AUS explantation.Patients and MethodsData of all patients undergoing AUS implantation due to stress urinary incontinence (SUI) in our tertiary center were prospectively collected from 2009 to 2015. In case of cuff erosion, AUS explantation was carried out in an inst…
Risk factors for resurgery in men with artificial urinary sphincter: Role of urethral strictures
2017
Objective: The aims of the present study were to evaluate the outcome of implantation of an artificial urinary sphincter (AUS) in male patients with iatrogenic urinary incontinence and to analyse possible risk factors for resurgery, with particular focus on the effects of posterior urethral strictures (US). Methods: The outcomes of AUS implantation surgeries performed by 2 surgeons on consecutive patients between January 1999 and 2015 were evaluated retrospectively. Univariate analysis with Cox proportional hazard regression was used to assess correlations between resurgery (explantation or substitution of the urethral cuff) and risk factors. Hazard ratios (HR) associated with AUS survival …
Antibiotic Coating of the Artificial Urinary Sphincter (AMS 800): Is it Worthwhile?
2016
Objective To investigate the impact of the antibiotic coating InhibiZone on the infection and explantation rates of the AMS 800 in comparison to the AMS 800 without InhibiZone. Materials and Methods We retrospectively identified 305 patients with an AMS 800 in a multicenter cohort study. Patients were subsequently divided into InhibiZone and without InhibiZone-coated groups. Infection and explantation rates were analyzed by univariate and consecutively by multivariate logistic regression adjusted to variable risk factors. The infection-free interval was estimated by Kaplan-Meier plot and compared by the log-rank test. A P value below .05 was considered statistically significant. Results We …
Artificial Urinary Sphincter Cuff Size Predicts Outcome in Male Patients Treated for Stress Incontinence: Results of a Large Central European Multice…
2019
Purpose The aim was to study the correlation between cuff size and outcome after implantation of an AMS 800 artificial urinary sphincter. Methods A total of 473 male patients with an AMS 800 sphincter implanted between 2012 and 2014 were analyzed in a retrospective multicenter cohort study performed as part of the Central European Debates on Male Incontinence (DOMINO) Project. Results Single cuffs were implanted in 54.5% and double cuffs in 45.5% of the patients. The cuffs used had a median circumference of 4.5 cm. Within a median follow of 18 months, urethral erosion occurred in 12.8% of the cases and was associated significantly more often with small cuff sizes (P<0.001). Multivariate ana…
Two-stage transperineal management of posterior urethral strictures or bladder neck contractures associated with urinary incontinence after prostate …
2007
Objectives: The treatment of posterior urethral strictures or bladder neck contracture associated with severe urinary incontinence after prostate surgery and failure of endoscopic treatments is controversial. We report our experience with a transperineal approach in two steps: end-to-end urethroplasty/anastomosis and subsequent artificial urinary sphincter implantation.Methods: Between September 2001 and January 2005, we observed six patients (58-68 yr old), with a combination of severe urinary incontinence and posterior urethral stricture with anastomotic bladder neck contracture after prostate surgery. In all cases, repeated endoscopic treatments of the strictures failed. The patients und…
Risk Factors for Failure of Male Slings and Artificial Urinary Sphincters: Results from a Large Middle European Cohort Study.
2016
<b><i>Introduction:</i></b> We analysed the impact of predefined risk factors: age, diabetes, history of pelvic irradiation, prior surgery for stress urinary incontinence (SUI), prior urethral stricture, additional procedure during SUI surgery, duration of incontinence, ASA-classification and cause for incontinence on failure and complications in male SUI surgery. <b><i>Materials and Methods:</i></b> We retrospectively identified 506 patients with an artificial urinary sphincter (AUS) and 513 patients with a male sling (MS) in a multicenter cohort study. Complication rates were correlated to the risk factors in univariate analysis. Subsequentl…
Transrectal ultrasound guided implantation of the ProACT adjustable continence therapy system in patients with post-radical prostatectomy stress urin…
2006
Purpose: We evaluate the feasibility and potential advantages of ProACT system implantation using transrectal ultrasound rather than fluoroscopy for guidance. Materials and Methods: The transrectal ultrasound guided procedure was done between June and October 2005 in 7 patients with a mean age of 68.4 years (range 53 to 76) with mild to severe stress urinary incontinence after laparoscopic transperitoneal radical prostatectomy. Results: The ProACT system was successfully implanted in all cases without perioperative complications. Time needed to complete the overall procedure was 15 to 30 minutes. All transrectal ultrasound studies performed during the mean followup of 4.2 months (range 2 to…
Targeting Moderate and Severe Male Stress Urinary Incontinence With Adjustable Male Slings and the Perineal Artificial Urinary Sphincter: Focus on Pe…
2017
Purpose: To analyze perioperative complications and postoperative explantation rates for selected readjustable male sling systems and the perineal single-cuff artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort. Methods: Two hundred eighty-two male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included in the study (n = 127 adjustable male sling [n = 95 Argus classic, n = 32 Argus T], n = 155 AUS). Perioperative characteristics and postoperative complications were analyzed. The explantation rates of the respective devices were assessed using the Fisher exact test and the Mann-Whitney U-test. A Kapl…
The impact of perioperative complications on favorable outcomes after artificial urinary sphincter implantation for post-prostatectomy incontinence
2020
ABSTRACT Objective To investigate the effect of perioperative complications involving artificial urinary sphincter (AUS) implantation on rates of explantation and continence as well as health-related quality of life (HRQOL). Materials and methods Inclusion criteria encompassed non-neurogenic, moderate-to-severe stress urinary incontinence (SUI) post radical prostatectomy and primary implantation of an AUS performed by a high-volume surgeon (>100 previous implantations). Reporting complications followed the validated Clavien-Dindo scale and Martin criteria. HRQOL was assessed by the validated IQOL score, continence by the validated ICIQ-SF score. Statistical analysis included Chi (2) test, M…
