[Cutaneous ureterostomy with vascular prosthesis. Preliminary results of a new technique].

Cutaneous ureterostomy represents a simplified and less traumatic alternative for urine diversion. The small diameter ureter is often responsible for stenosis of the stomal end. In order to avoid this complication, we developed a surgical method with application of vascular endoprosthesis to prevent stenosis of the ureter. The method was first applied experimentally, and later on 12 patients. A description of the method and the results for the first 12 patients are given. The lack of complication and the good functional results are encouraging, but a longer follow-up and more patients are needed for final evaluation.
