Interventional angiographic partial nephrectomy for idiopathic massive renal bleeding.

In a patient with idiopatic massive renal bleeding in which dominant abnormal findings could not be identified even by various diagnostic imaging methods, we selectively infused absolute ethanol and a stainless steel coil into one of the renal arteries to stop bleeding. CT two weeks after arterial embolization revealed the infarcted area in the lower pole of kidney. There was no evidence of hypertension or renal failure secondary to artificial renal infarction.
