[Reconstructive-restorative microsurgical operations in cicatricial ureteral stenosis of tuberculous etiology].

The authors describe a new method of operative intervention with cutting a flap out of the urinary bladder wall. The urinary bladder is anastomosed with the ureter with the help of nodular microsurgical sutures put from the outside, the antireflux protection being realized distal to the zone of anastomosis by the formation of two urinary bladder flaps and their suture "cross by cross" in front of and behind the base of the created urinary bladder tube. Experimental and clinical materials showing the effectiveness of the proposed treatment are described.
