Influence of preoperative bladder capacity and compliance on the outcome of artificial sphincter implantation in patients with neurogenic sphincter incompetence.

We performed a retrospective study of 23 patients with neurogenic sphincteric incompetence who had undergone implantation of an artificial urinary sphincter to determine if bladder capacity and compliance as determined by cystometrography could predict the need for enterocystoplasty. Study criteria were neurogenic sphincteric incompetence, no previous operations on the lower urinary tract, and performance of preoperative and postoperative cystometrography. Patients were 5 to 17 years old at implantation.
