Introduction and objectives: From 2006 to 2013 the authors have 5 patients ureteral stenosis posttransplantation. The outcome resulted from the treatment of these 5 cases of ureteral stenosis has provided us some valuable experiences for further management of this relatively rare complication of the kidney transplantation. Patients and method: This study was conducted in a period from 2006 to 2013 at Viet-Duc Hospital in a small group of 5 patients with ureteral stenosis occurring after kidney transplantation. Results: This studied series consisted of 4 male patients and 1 female. The average age of the patients was 40.8 years (range: 33-51 years). The mean time from the date of kidney transplantation to the date of ureteral stenosis diagnosis was 2 months. All 5 patients were initially treated by endoscopic ureteral dilation and ureteral stent placement. In the first attempt this procedure was successfull in 3 out of 5 patients, but failed in the 2 others. In three patients with successful! stent placement, however, ureteral stenosis recurrence developed 4 weeks after the stent removal; a second stent placement had been performed but with no success. Ureteral reconstruction was performed using these methods: ureterovesical reimplantation using the Lich-Gregoir technique in 3 patients. Recontruction using the Boari method in 1 patient; and in one patients because of a too long ureteral stenosis the authors had to perform a native-to-transplant ureteropyelostomy after having excised the stenosed ureter. Conclusion: The result of this study suggests that open plastic surgery may be a safe and effective approach for the treatment of post-renal transplant ureteral stenosis.
