Comparing Argus sling and artificial urinary sphincter in patients with moderate post-prostatectomy incontinence.

Abstract

Post-prostatectomy incontinence (PPI) is a main complication of radical prostatectomy. The purpose of this study was to compare the efficacy and safety of the Argus male sling (Argus) with that of artificial urinary sphincters (AUS) in patients with moderate PPI. A total of 33 moderate PPI patients underwent AUS or Argus implantation from January 2009 to June 2013 (13 AUS, 20 Argus). We defined moderate PPI as the use of 2–4 pads per day. To compare efficacy, we assessed the success rate between the two groups. Success was defined as the daily need for no pads or one small safety pad that remained dry most of the day. The mean patient age was 73.5±6.3 yr in the AUS group and 70.9±5.1 yr in the Argus group, and the mean follow-up period was 29.8±14.9 months in the AUS group and 24.7±11.8 months in the Argus group. The success rate was 72.7% in the AUS group and 85.0% in the Argus group (P=0.557). Abnormal postoperative pain persisted in more patients in the Argus group (6/20, 30%) than in the AUS group (1/13, 7.7%) (P=0.126). However, the rate of other complications was not different between the two groups (7.7% and 15.0% for AUS and Argus, respectively, P=0.822). Argus surgery showed similar success and complication rates to those of AUS in moderate PPI patients, indicating that it could be an alternative surgical option for the treatment of moderate PPI.
