Abstract

PURPOSE
To evaluate the role of antegrade balloon dilatation and uteteral stenting in benign ureteral strictures.
METHODS
AND MATERIALS: Percutaneous antegrade balloon dilatation was attempted in 46 patients with benign ureteral strictures. The underlying causes of the strictures were urinary tract tuberculosis in 20 patients, congenital ureteropelvic junction obstruction in eight, ureteroneocystostomy or ureteroileostomy state in five, postoperative or post-extracorporeal shock wave lithotripsy state for ureteral calculi in eight, ureteral injury during surgery in four, and retroperitoneal fibrosis in one.
RESULTS
Antegrade balloon dilatation was performed with initial technical success in 43 patients but the procedure was aborted in the remaining three with urinary tract tuberculosis due to the failure in passing a guidewire through the stenotic lesions. Intravenous urograms obtained 4-76 months after the procedure showed improvements in 76%(13/17) with urinary tract tuberculosis, in 63%(5/8) with congenital ureteropelvic junction obstruction, in 88%(7/8) with strictures associated with ureteral calculi, and in 100%(4/4) with iatrogenic ureteral injury. The results were relatively poor in strictures of the ureteral anastomosis(1/5) and in ureteralstrictures associated with retroperitoneal fibrosis(0/1).
CONCLUSION
Antegrade balloon dilatation of the urinary tract combined with ureteral stenting was an effective technique for the management of the benign ureteral strictures.
