Long-term functional outcomes after artificial urinary sphincter implantation in women with stress urinary incontinence.
OBJECTIVE
To assess the long-term outcomes obtained after artificial urinary sphincter (AUS) implantation in women with stress urinary incontinence (SUI).


METHODS
Women with SUI caused by intrinsic sphincter deficiency who underwent an AUS placement between 1984 and 1992 were included. Explantation, revision and deactivation rates of the AUS were reported. Continence, defined as no pad use, was assessed at the end of the follow-up. Kaplan-Meier survival curves were generated to evaluate the survival rate of the device without explantation or revision.


RESULTS
A total of 34 patients were included. The median (interquartile range [IQR]) age of the patients at surgery was 56.5 (50-64.7) years and the median (IQR) follow-up was 17 (12-19) years. Overall, 26 women (74%) still had their AUS in place at the end of the follow-up, while eight patients underwent an explantation of the device. The 10-, 15- and 20-year device survival rates without explantation were 80, 80 and 74%, respectively. The 10-, 15- and 20-year survival rates of the device without revision were 79, 65 and 40%, respectively. After 20 years of follow-up, 11 women still had successful outcomes (61%).


CONCLUSIONS
The AUS provided satisfactory very long-term functional results among women with SUI caused by intrinsic sphincter deficiency.
