Methods: A retrospective cross-sectional study was conducted to evaluate 1050 patients with end - stage renal disease who underwent renal transplantation at Hue Central Hospital from January 2016 to September 2023. Results: The age group of 18 - 60 accounted for 95.1% of patients, and males accounted for 73.2%. The average time for ureteroneocystostomy surgery was 20.8 ± 6.1 minutes. The mean time for ureteral drainage was 5.8 days, surgical site drainage was 4.8 days, and removal of the JJ stent was 23.7 days. The most common complication following kidney transplantation was ureteral stricture, accounting for 4.1% of cases. Ureteral strictures were treated medically in 83.7% of cases, with interventional procedures in 16.3% of cases. 86% of ureteral stricture cases occurred within the first month after removal of the JJ stent.Conclusion: The Lich - Grégoir ureteroneocystostomy technique in kidney transplantation is a safe and effective procedure associated with low complication rates. The most common complication encountered was stricture formation at the ureteroneocystostomy anastomotic site
