Modified extravesical ureterocystoneostomy of the kidney transplant allograft with completely duplicated ureters

Background: The technique of ureterocystoneostomy for completely duplicated ureters has not yet been established. We report on a case of a living-related transplant recipient who successfully received his mother's kidney having completely duplicated ureters. Methods/Results: The recipient was a 33-year-old male patient introduced to hemodialysis due to focal glomerulosclerosis. The donor was his 60-year-old mother having left completely duplicated ureters. We adopted the modified extravesical ureterocystoneostomy technique. Postoperative drip infusion pyelography and voiding cystography of the recipient showed no evidence of urinary tract obstruction or vesicoureteral reflux. Conclusions: We conclude that this technique is suitable for the transplantation of the kidney with complete ureteral duplication.
