title: Massive renal hemorrhage owing to polyarteritis nodosa.
abstract: We report a case of massive renal hemorrhage owing to unsuspected polyarteritis nodosa. The bleeding was ultimately controlled by embolization of the renal artery. The findings on renal angiography and enhanced computerized tomography were characteristic of the disorder and they should be familiar to all urologists.
