Abstract
Balloon catheter dilatation is now an accepted method for treating strictures of the upper urinary tract. A successful result was obtained in 34 (85%) of 40 patients with symptomatic stricture. The number of dilatations required for improved runoff from the kidney was one in 26 cases, two in six cases and three in one case. One patient had a permanent stent and six required a conventional operation. There were seven recurrences of stricture, all within 4 months after the dilatation. One of these patients required nephrectomy because of nonfunctioning kidney.
