title: The cold-knife technique for endourological management of stenoses in the upper urinary tract.
abstract: Between 1985 and October 1989 we managed 13 patients with primary and 43 with secondary obstruction of the upper urinary tract with the endourological cold-knife technique. We treated 26 patients with stenosis of the ureteropelvic junction, 9 with infundibular stenosis, 12 with ureteral obstruction after inflammation or radiation therapy, 7 with stricture of the ureter in kidney transplants and 2 with stenosis of the ureter after ureterosigmoidostomy. Endourological management was successful in 42 of 56 cases with a decrease or total elimination of obstruction. Stenosis recurred in 9 patients. Our results indicate that the cold-knife technique should be attempted as the initial approach in all cases of primary or secondary obstruction of the upper urinary tract.
