Neuropathic urinary incontinence in pediatric patients: management with artificial sphincter

From June 1982 to November 1990, 37 patients, aged 13 to 19 years (35 males and 2 females), were treated in our division for neuropathic urinary incontinence with an artificial sphincter. All patients were treated before sphincter implantation with drugs, transurethral sphincterotomy in boys, and bladder flap urethroplasty was carried out in females during the surgical procedure. The cuff was placed at the bladder neck in 33 cases, and in 4 cases at the urethral bulb. The sphincter was activated about 3 weeks after implantation and after 2 months in two patients with associated bladder augmentation. Operative and perioperative complications occurred in four cases during the initial phase of our experience. Later we had to perform 19 revisions on 14 patients due to mechanical and surgical failure (reoperation rate, 0.38). Thirty-three patients are presently dry (90% of successes). Postoperatively, normal upper urinary tract conditions were found in all patients except two.
