Percutaneous balloon dilatation of ureteral strictures

Balloon dilatation and insertion of temporary coated stents using a retrograde approach in patients with irreversible strictures of the distal ureter

“…1,7,10.11 Short, annular, avascular, hard strictures can be treated successfully only with balloon-catheter dilatation. 8,12 The choice and the order of the treatment methods used depend on the duration of the stricture, duration of PCN residence in the body, and the morphology of the stricture. The latter is evaluated by CT urography combined with administration of radiopaque contrast through the PCN catheter, if the patient has one.…”

Percutaneous balloon catheter dilatation of benign ureteral strictures: effect of multiple dilatation procedures on long-term patency.

“…The overall success rates of percutaneous dilatations of unetenal strictures with a balloon catheter reported vary markedly from 16% to 83% [3][4][5][6][7][8][9][10]. In our series of 28 uneteral stnictunes, all patients initially responded to the balloon dilatation.…”

Tuberculous stricture of the urinary tract: Antegrade balloon dilation and ureteral stenting

“…An antegrade or retrograde balloon dilation in benign ureteral strictures of various causes has produced generally favorable results [2][3][4][8][9][10][11][12][13][14][15]. Factors which have been reported to affect the results of balloon dilation are cause, location, length, and duration of the strictures, as well as presence or absence of the vascular compromise [2][3][4].…”

“…suits of the antegrade or retrograde balloon dilation of the benign ureteral strictures, and they regarded the age of the stricture and vascular supply to the lesion as the prime determinants of a success of the procedure [2][3][4]. Although cystoscopic dilatation and stent placement for tuberculous ureteral strictures have been described [1,[5][6][7]] and a few previous reports of ureteral balloon dilation have included cases of tuberculous strictures [4,8,9], the results of antegrade balloon dilation in a series of patients with urinary tract tuberculosis have not been specifically documented.…”
