Experience with AS 800 artificial sphincter in pediatric and young adult patients.

Congenital or acquired sphincteric urinary incontinence in children and young adults is a severe social and physical burden. As a therapeutic option, we implanted 61 AS 800 artificial sphincters in 59 patients (46 males and 13 females). The mean age of the patients was 17.5 years (range, 6 to 34 years), and mean follow-up was forty-three months (range, 5 to 84 months). In addition to artificial sphincter implantation, intestinal cystoplasty was required in 22 patients to obviate problems of increased detrusor contractility or decreased detrusor compliance, or both. Continence was good in 47 patients (80%) and fair in 8 (14%). Four patients (7%) were awaiting sphincter modification or cystoplasty, or both. Careful and prolonged follow-up is mandatory in all patients managed in this fashion to preclude the deleterious effects of subtle changes in detrusor or ureteral function on the integrity of the upper urinary tracts.
