Tuberculous stricture of the urinary tract: antegrade balloon dilation and ureteral stenting.
In eight patients with tuberculous strictures of the urinary tract, antegrade balloon dilation and ureteral stenting was attempted. In six patients, antegrade balloon dilation was successfully performed; however, the procedure was aborted in the remaining two patients due to the failure in passing a guidewire through the stenotic lesions. In six patients in whom balloon dilation and ureteral stenting were performed, a total of nine stenotic lesions were dilated. Those were four ureteric lesions, two lesions of ureteropelvic junctions, two lesions of ureterovesical junctions, and a lesion of calyceal infundibulum. In all six patients in whom balloon dilation and ureteral stenting was successfully accomplished, intravenous urograms obtained 9-31 months after the procedure showed improvements both in contrast media excretion and in prestenotic dilatation. Antegrade balloon dilation of the urinary tract combined with ureteral stenting was an effective technique for the management of stenoses secondary to tuberculosis of the urinary tract.
