title: Balloon catheter dilation of ureteroenteric strictures: long-term results.
abstract: Balloon catheter dilation of benign ureteroenteric anastomotic strictures has been proposed as an alternative to either surgical revision or chronic ureteral stenting, with moderately successful short-term results reported by several groups in a limited number of patients. However, the authors' experience with 29 patients exhibiting 37 benign ureteroenteric strictures treated over the past 7 years revealed that in the majority of cases (23 patients, 26 strictures [70%]), strictures recurred within 6 months of balloon catheter dilation/ureteral stent therapy. Furthermore, of the 11 strictures that appeared to have been successfully dilated at a follow-up interval of 6 months, five restenosed within 1 year. Therefore, only six of 37 (16%) ureteroenteric stricture dilations could be considered successful when viewed at least 1 year after interventional therapy. Furthermore, repeat dilations have often been required to maintain ureteral patency in these patients.
