Introduction:
After implantation of an artificial urinary sphincter (AUS) due to stress urinary incontinence, in some cases revision procedures may be necessary. This is mostly due to device infection or cuff erosion in the long term. The aim of this study was to evaluate the impact of early revision procedures (prior to or immediately after AUS activation) on the long-term outcome.
Methods:
We retrospectively evaluated patients who underwent primary AUS implantation between 2006 and 2019. Patients with previous radiotherapy, urethroplasty, urethral stent placement, or repeat AUS implantation were excluded. Early revision was defined as prior to or immediately after AUS activation and comprised pump repositioning or cuff size adaptation due to difficulties in using the pump, persistent urinary incontinence, or urinary retention. Patients were compared with regard to complication rates, functional outcome, and patient satisfaction. Univariable and multivariable logistic regression analyses were performed to analyze risk factors for early AUS revision. Kaplan-Meier analysis evaluated explantation-free survival.
Results:
A total of 250 patients were included. Twenty patients (8%) required early revision (pump repositioning in 15 cases [75%], cuff downsizing in 3 cases [15%], and cuff upsizing in 2 cases [10%]). Mean follow-up was 78.6 months. 96.4% of all patients were objectively continent at the time of last follow-up without differences between both groups, and patient satisfaction was high in both groups. No differences with regard to mechanical implant failure, tissue atrophy, and AUS explantation due to cuff erosion or implant infection were observed. Explantation-free survival was comparable in both groups. On univariable logistic regression analysis, coronary artery disease and transcorporal cuff placement were associated with early AUS revision.
Conclusion:
Early revision after AUS implantation can be performed without negative impact on the long-term outcome.
