[Congenital intraparenchymatous renal arteriovenous fistulas]

The authors report a new case of congenital renal arteriovenous fistula (AVF) in a young adult, who presented with gross haematuria. The diagnosis and treatment of this rare disease required collaboration between the urologist and radiologist. The key examination is renal arteriography, allowing selective embolization of the lesion. Conventional surgery now has a usually limited place, following failure of embolization.
