[Renal arteriovenous fistula detected 25 years after nephrolithotomy: a case report].

We report a case of intrarenal arteriovenous fistula (AVF) with macroscopic hematuria detected after nephrolithotomy performed 25 years previously. The present case, successfully treated by transcatheter embolization with steel coils, is the eighth case of postnephrolithotomy AVF reported in English and Japanese literatures. The necessity of renal arteriography in patients with postoperative massive hematuria is stressed.
