title: A renal cause for massive retroperitoneal hemorrhage--renal angiomyolipoma.
abstract: In any case of intra-abdominal trauma or hemorrhage a preoperative IVP is essential to determine the renal status. Preoperative catheter occlusion of the renal artery in these vascular tumors may be attempted to decrease blood loss. Stigmas of tuberous sclerosis should be sought in patients with vascular renal tumors, especially if they are bilateral. Conservation of renal tissue in tuberous sclerotic patients harboring renal angiomyolipomas is important.
