Abstract

Interventional uroradiologic management of ureteral stricture is recently getting more interest due to its greater advantages than surgical management and rapid development of radiologic imagine technique. We performed 47 interventional management for ureteral stricture during 7 years between March 1986 and February 1993. The underlying diseases or conditions of the ureteral stricture were invasion of tumor in 22 cases, tuberculous ureteritis in 13, surgery to ureter in 8, ureteroneocystostomy in renal transplantation in 2 and retroperitoneal fibrosis in 2. According to their individual conditions such as underlying cause, location. age and severity of stricture. ureteral managements by balloon dilatation only or stenting only or balloon dilatation combined with stenting were performed As a result of these managements and follow up of at least 2 months, complete relief of uretera1 obstruction and marked improvement of renal function were observed in 9 cases(19%), preservation or renal function and minimal improvement of obstruction were observed in 24(51%) and progression of ureteral stricture and aggravation of renal function were observed in 14(30%). So. this study showed that if we are aimed at prevention of progression of ureteral stricture and preservation of renal function. interventional management had great merit of 70% of success rate. Complications occurred in 7 cases which consisted of obstruction in 3, migration of stent in 2, urinary tract infection in 1, irritation in 1 and severe hematuria in 1. These complications were managed by conservative treatments with no sequelae.
