Abstract:
Objective To investigate the long-term efficacy and postoperative complications of artificial urinary sphincter (AUS) implantation in patients with stress urinary incontinence caused by traumatic urethral injury, so as to provide reference for the treatment of this condition. Methods A retrospective study was conducted on the clinical data of 26 patients treated at our center during Apr.2002 and Dec.2024. All patients had severe persistent urinary incontinence due to traumatic urethral injury and underwent AUS implantation. The daily pad usage and visual analog scale (VAS) scores before surgery and 6 months to 1 year after surgery were compared to evaluate the efficacy. Complications were recorded and analyzed, and the survival was analyzed using the Kaplan-Meier method. Results The patients included 25 males and 1 female, with a mean age (41.8± 16.0) years, median disease duration of 10.0 (2.0,16.0) years and follow-up of (11.7±5.9) years. One month postoperatively, all patients successfully activated the AUS device. At the latest follow-up (Jun.2025),20 devices (including 3 revised) were functioning. The social continence rate was 61.5% (16/26), and complete continence rate 38.5% (10/26). Daily pad usage decreased significantly from a preoperative median of 3.5 (3.0,5.0) pads/day to 0.5 (0,1.0) pads/day (P<0.05). The median VAS score decreased from 8.0 (7.0,8.0) to 1.0 (0,1.0) (P<0.05). Complications occurred in 34.6% (9/26) patients, including urethral erosion (4 cases), fluid leakage (3 cases) and infection (2 cases). There was a significantly difference in age between patients with complications and those without complications [ (33.1±12.3) years vs. (46.4±16.1) years, P<0.05]. The median survival was 16 years, with the 5-year,10-year, and 15-year survival probabilities of 75.8%, 75.8% and 58.3%. Conclusion AUS implantation demonstrates good long-term efficacy and durability, and is a recommended treatment option.
