Stress urinary incontinence in female neurological patients: long‐term functional outcomes after artificial urinary sphincter (AMS 800TM) implantation

Aims To report the long‐term functional outcomes of artificial urinary sphincter (AUS) implantation in female adult neurological patients suffering from stress urinary incontinence (SUI) due to sphincter deficiency. Methods Female patients with neurological disease suffering from SUI due to sphincter deficiency who underwent AUS (AMS 800TM) implantation between 1984 and 2011 were included. Continence rate defined as no need for pads and survival rates of the device without needing explantation or revision using Kaplan–Meier curves were reported. Results Overall, 26 patients, median age 49.2 years (IQR 28.5–59.7) were included. The median follow‐up time was 7.5 years (IQR 3.9–23.8). At the end of follow‐up period, 15 patients (57.7%) still had their primary AUS. The AUS was explanted in five women because of infection or erosion. Survival rates, without AUS explantation were 90%, 84%, 84%, and 74% at 5, 10, 15, 20 years, respectively. Survival rates without AUS revision were 75%, 51%, 51%, and 51% at 5, 10, 15, 20 years, respectively. 71.4% of patients with AUS were continent. When considering the 26 initial patients, including the patients in whom the AUS was explanted, the continence rate was 57.7%. Conclusions For treating neurogenic sphincter deficiency in the long term, the AMS 800TM can offer a satisfying rate of continence to female patients, with a tolerable rate of explantation and revision.
