Abstract
Percutaneous incision and balloon catheter dilation of the ureteropelvic junction (UPJ) was performed in nine patients with secondary UPJ strictures. In all patients, the UPJ was successfully dilated, and no immediate complications were encountered. After a postoperative follow-up period of 4-27 months, six patients showed marked improvement on excretory urograms. Three patients had recurrent obstruction after 3-18 months. The 66% success rate of percutaneous balloon dilation with or without endopyelotomy compares favorably with the success rate of open surgical repair of secondary UPJ strictures in adults.
