Arterial embolization to control renal hemorrhage in patients with percutaneous nephrostomy.

Two patients with renal hemorrhage treated by arterial embolization are reported. In one patient, one kidney was injured and the another had poor function. The other patient had one kidney. Although both patients had hematuria and underwent percutaneous nephrostomy, the bleeding location was not detected angiographically. Repeated embolization and irrigations through a nephrostomy catheter following each embolization arrested the bleeding.
