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.
