OBJECTIVES: To report our results after antegrade endoscopic treatment of @entity1901 with @entity384 with or without holmium laser endoureterotomy. @entity1901 is the most common long-term urologic complication of renal transplantation. METHODS: From July 2000 to October 2002, 9 renal transplant @entity1 with @entity1695 diagnosed by an increase in serum @entity1011 and radiologic evidence presented for endoscopic treatment. All @entity1 were treated with nephrostomy tube drainage followed by antegrade flexible nephroureteroscopy and @entity384 of the stricture. Three @entity1 required holmium laser endoureterotomy during the same procedure because of fluoroscopic and endoscopic evidence of persistent stricture. All @entity1 were treated with ureteral stents and nephrostomy tubes postoperatively. The median follow-up was 24 months (range 6 to 32). RESULTS: The site of stenosis was at the ureterovesical @entity254 in all @entity1 , and the mean stricture length was 0.28 cm. Two @entity1 had previously undergone ureteroneocystostomy for prior @entity1901 . Six @entity1 (66%) required only @entity384 , and 3 @entity1 (33%) also required holmium laser endoureterotomy. The median ureteral stent and nephrostomy tube duration was 40 and 62 days, respectively. The mean serum @entity1011 level was 2.3 mg/dL at presentation and 1.7 mg/dL at the last follow-up visit. After a median follow-up of 24 months, the ureteral patency and graft function rates were both 100%. No perioperative @entity532 occurred. CONCLUSIONS: Balloon dilation with or without holmium laser endoureterotomy was successful and safe in this group of renal transplant @entity1 with short ureterovesical anastomotic strictures.
