[Baloon dilatation of benign ureteroileal anastomotic strictures]

The study is presenting own experience with the use of percutaneous balloon angioplasty in the patients with the strictures of ureteroenteric anastomoses. A study group consisted of 11 patients with urinary bladder cancer in whom ureteroenteric anastomosis was performed. All patients developed in the postoperative period ureter strictures or the stenosis at the junction point of ureteroenterostomy resulting in retention of urea in the ureter and pyelocalyceal system requiring percutaneous nephrostomy. High-pressure balloon catheter inserted through the nephrostomy was placed centrally in the point of stenosis. The catheter was insufflated with physiological saline solution and contrast agent until ballon waisting disappeared. Subsequently temporary double-J catheter with diameter of 9 F or 12F was inserted and remained in place for the period of 1-6 months. All patients were followed-up for 2 years, and underwent control USG and CT examinations. Fourteen urethral dilatations of bilateral strictures were performed in 3 patients and in 9 patients with unilateral strictures. In 10 (71%) cases the symptoms of stenosis disappeared for the period of 1 year. Procedure of ballon dilatation follow by introduction of the double-J catheter should be method of first choice in all cases of benign ureteroileal anastomotic strictures.
