Endourological management of ureteroileal anastomotic strictures: is it effective?

Ureteroileal stenosis represents a serious postoperative threat to the obstructed kidney and open revision in these patients often is difficult. We evaluated 9 patients with 10 ureteroileal strictures who were treated with semirigid fascial dilators (1), balloon dilation (4) or a combination of balloon dilation and percutaneous intraureteral surgery (4). All 5 patients who had semirigid fascial or balloon dilation alone had early recurrence of the strictures. However, in 4 patients dilation in conjunction with percutaneous intraureteral incision of the stricture through a flexible choledochonephroscope resulted in short-term resolution of each ureteroileal stricture. However, by 6 months these strictures had recurred in 50 per cent of the patients.
