The authors have made extensive studies of ureteroneocystostomies, that are intravesical and extravesical methods, and postoperative urological complications on 58 cases of living related renal transplants and 12 cases of cadaveric renal transplants at the Second Department of Surgery, Hiroshima University School of Medicine.

Among the 21 cases in whom intravesical ureteroneocystostomy was employed, there was one case of urinary fistula.

Among the 49 cases in whom extravesical ureteroneocystostomy was employed, two case of postoperative bleeding, a case of stenosis of the ureter and a case of urinary fistula of the anastomosis were observed.

There was one case of graft loss in each method, but no case died.

The incidence of complications is low on both methods. But extravesical ureteroneocystostomy does not require a large incision of the vesical wall and is advantageous in having a possibility to conduct the submucosal tunnel visually and a easy doing of anastomosis between the ureter and the vesical mucosa.

Then, the procedure of our modified extravesical ureteroneocytostomy was reported.
