Reconstruction of the urinary tract after diversion has been successful in patients with normal innervation of the lower tracts. However, the possibility of urinary incontinence after such major surgical procedures has dissuaded many surgeons from attempting urinary undiversion in patients in whom the continence status cannot be determined accurately before the operation or who were known to be incontinent before the original diversion. For this reason, the presence of neuropathic bladder dysfunction has been considered a relative contraindication to urinary undiversion unless it can be established preoperatively that the patient will obtain urinary continence. Eight patients are reported who had successful outcome with the use of the AS792 artificial urinary sphincter to control incontinence after urinary undiversion. Because of this successful experience it is now believed that patients with neuropathic bladder dysfunction or anatomically abnormal lower tracts are no longer precluded from urinary undiversion. A variety of methods has been used to reconstruct the urinary tract, including total reconstruction of the bladder and urethra with the sigmoid colon in 1 case. In the latter case the artificial sphincter was placed around the bowel segment to provide continence. The use of the artificial sphincter around a bowel segment offers many possibilities for reconstructive procedures involving bowel in the future.
