Abstract Background: We determined the long‐term result of our percutaneous antegrade balloon dilation technique performed for adult patients with ureterointestinal anastomotic stricture between 1992 and 1997. Methods: Balloon dilation was performed on 13 ureterointestinal anastomotic strictures in 10 patients. After a nephrostomy was performed, a guide wire was introduced into the intestinal loop through the stenotic portion under direct observation using a ureterorenoscope. Dilation was performed using the Olbert balloon dilator (30‐Fr) inserted along a guide wire into the stenotic portion. A 20‐Fr or 22‐Fr multihole catheter was left for approximately 6 weeks. No major complications were encountered during or after these procedures. After removal of the indwelling catheters, the progress of each patient was followed for at least 14 months. Results: Additional dilation was necessary in three of 10 patients for the recurrent stricture. The balloon dilation was ineffective in two patients with a long stenosis of the ureter or a previous history of radiation therapy for uterine cancer. Eight of 10 patients showed satisfactory outcomes during the mean follow‐up period of 47.1 months. Conclusions: Based on these results, we believe that the balloon dilation could be the first line of treatment for strictures of uro‐digestive anastomosis, except for some patients with a long stenosis or a previous history of intrapelvic radiation.
