A case of congenital arteriovenous fistula diagnosed by measuring the oxygen saturation difference of renal veins at the time of selective renal angiographic examination and a review of 38 relevant Japanese cases are reported. The English as well as the Japanese literature was reviewed. Treatment has consisted of partial nephrectomy, ligation of the branch artery supplying the fistula and intentional embolization of the arterial branches, feeding the shunt by catheter.
