Renal varices.
Renal vein varices are abnormalities known to be responsible for intermittent hematuria, but may be found in patients with no history of bleeding. Diagnosis is suggested by characteristic changes on a drip infusion pyelogram and retrograde pyelogram and is made by renal venography done seconds after the injection of epinephrine into the ipsilateral renal artery.
