We report 2 cases of kidney autotransplant for patients with long loss of upper ureter at Hue Central Hospital. Ureteral injury occurs due to complications of previous surgery such as endoscopic retrograde lithotripsy and retroperitoneal re - insertion of the ureter into the bladder with ureteral stone removal. Two patients had kidney surgery with ureteral lesions grafted into the contralateral iliac fossa: renal artery transplantation into the external iliac artery, renal vein into the external iliac vein by end - to - side anastomography and ureteroscopy by Boari flap (case 1) and Lich - Gregoir procedure (case 2). Both patients were discharged after 2 weeks, and the JJ catheter was removed after 1 month. Post - operative follow - up 2 patients were completely healthy, the parameters of the transplanted kidney were within normal level. The success is a premise for us to indicate kidney autotransplant incase long ureteral loss, complicated renal vascular disease, large kidney tumor, large kidney stone.
