[Renal arteriovenous fistulae].

Arteriovenous fistulas (AVFs) involving the kidney are rare. They are generally classified as congenital, idiopathic or acquired. The authors present 5 cases of renal arterio-venous communications observed in recent years. These cases don't include the congenital type and represent the forms of AVFs that are more frequently observed (1 idiopathic, 3 iatrogenic, 1 associated with malignancy). This study is aimed at examining the clinical picture and the procedures of detection and monitoring of renal AVFs. The various adopted therapeutic procedures (nephrectomy, surgical ablation, radiological embolization) are analyzed.
