title: Angio-embolization of renal artery pseudoaneurysm after renal biopsy: a case report.
abstract: Renal artery pseudoaneurysm is a rare clinical entity that has been reported after renal biopsy, percutaneous renal surgery, penetrating trauma, and rarely blunt renal trauma. We present the case of a 37-year-old man with ruptured renal artery pseudoaneurysm accompanied by massive gross hematuria, urinary clot retention, and bladder tamponade, which were the presenting signs seven hours after renal biopsy. Abdominal CT scan showed a large perinephric, intracapsular hematoma of left kidney. His angiogram revealed a left renal segmental artery pseudoaneurysm that measured 1 cm x 1 cm. He was successfully treated by selective embolization of the arterial branch supplying the pseudoaneurysm.
