[Endoscopic ureterocutaneostomy]

The authors have developed and used in 16 patients an endoscopic technique of continuous drainage of the upper urinary tracts by means of ureterocutaneostomy and assisting retroperitoneoscopy. The most reliable cutaneous fistula not inclined to scarring or narrowing can be established of small triangular skin flap from the wound margin sutured into the 2-3 cm longitudinal incision of the ureteral stump (stump ureterotomy). Such fistula may even heal without further internal drainage. In a short ureteral stump skin anastomosis may be formed in the depth of the wound with the use of longer cutaneous graft.
