Abstract
We reviewed the records of 20 patients (21 ureters) treated during the last 5 years for ureteral stricture disease. The causes of stricture formation included ureterolithotripsy in 47.7% of the patients, open ureterolithotomy in 9.5%, other urological procedures in 23.8%, general surgical and gynecological procedures in 9.5% and miscellaneous factors in 9.5%. A total of 20 patients (21 ureters) underwent endourological treatment with balloon dilation (19) or balloon dilation and internal ureterotomy (2), with good results in 57.1% and a mean followup of 24 months. Of the 9 patients who failed endourological management 3 underwent successful open repair, 3 underwent nephrectomy, and 3 had a relatively large ureteral lumen and became asymptomatic, receiving no further treatment. The interval between injury and treatment was not a decisive factor. The length of ureteral stricture assumes the most significant parameter to predict success in the rreatment of ureteral stricture. There were no intraoperative or postoperative complications. The association of balloon dilation and incision by special endoureterotomy scissors is a potentially useful technique.
