Long‐term outcomes of primary implantation and revisions of artificial urinary sphincter in men with stress urinary incontinence

摘要

Aims To evaluate long‐term outcomes of primary implantation and revisions of artificial urinary sphincter (AUS) in men with stress urinary incontinence (SUI). Methods The medical records of 155 consecutive patients who underwent AMS 800? implantation from 2003 to 2015 were reviewed. Treatment success (TS) was defined as no need for pads, and social continence (SC) was defined as a need for pad ≤1/day at last follow‐up. The efficacy, complication rates, and associated risk factors with reoperation and durability of primary AUS implantation, as well as treatment outcomes following AUS revision were evaluated. Results The median age was 69.0 years (range 27‐85), and median follow‐up was 45.1 months (range 9‐126). The rates of TS and SC were 63.2% and 84.5%, respectively. The reoperation rate of AUS was 26.4%. Non‐mechanical failure (70.7%) was a dominant etiology of reoperation. The 5‐year device survival rate without reoperation was 67.0%. The immediate TS rates of primary AUS without reoperation (pAUS) and AUS revision without secondary reoperation (rAUS) groups were 88.6% and 79.2% ( P ?=?0.352), respectively. At last follow‐up, the SC rate was higher in patients with pAUS (92.1%) than with rAUS (62.5%) ( P ?=?0.001). Conclusions Although there are appreciable rates of reoperation, the AMS 800? offers high rates of continence in men with SUI. The immediate TS rate was comparable in patients with pAUS and rAUS. At the final follow‐up, however, the SC rate was significantly higher in patients with pAUS than with rAUS.
