Clinical Experience With An Alloplastic Stoma Prosthesis (Biocarbon®) For Urinary Conduits And Cutaneous Ureterostomy

Abstract

An alloplastic stoma prosthesis, Biocarbon®, composed of 99.9% pure carbon in vitreous form, was used in six patients with conduit urinary diversion and in seven with cutaneous ureterostomy. The patients were thereafter observed for 2–86 months. Complications were subcutaneous infection, urinary fistula and ureteral stenosis, which necessitated removal of the prosthesis in most cases. The permanent stoma, without need for adhesive collecting device, was appreciated by the patients. Problems relating to biocompatibility remain to be solved before the place of the stoma prosthesis in urinary diversion can be determined.
