ABSTRACT

Recently. the endopyelotomy has been used as a first choice of treatment in selected cases of ureteropelvic or ureteral strictures. 24 consecutive cages of endourologic-tomy procedure including 12 cases of endopyelotomy. 8 cases of endoureterotomy and 4 cases of endocalicotomy were performed from Nov. '89 to May '91. The causes of stricture were previous operation (7 cases), congenital (6 cases). tuberculosis (5 cases) and others. They were all followed more than 3 months. The overall success rete was 83.3%. The success means improvement of clinical symptoms and radiographic findings. The complications were upward migration of stent (1 case), granuloma (1 case) and re-stricture (2 cases). Especially in 1 cases of caliceal stricture the success rate was 100% with no complication. Our experience indicates that endourologic-tomy procedure has relatively good success rate, low morbidity, Low complication and a shorter recovery time. Especially endocalicotomy is one of the best method to treat caliceal stricture.
