Acute renal vein thrombosis: successful treatment with intraarterial urokinase

When acute renal vein thrombosis is associated with renal failure, aggressive therapy to eliminate the venous obstruction is indicated. There are reports of successful treatment of this condition with thrombolytic agents administered systemically or directly into the renal vein. Renal arterial administration of urokinase was used successfully to treat acute renal vein thrombosis associated with renal failure in a 9 1/2-year-old child.
