Abstract

Renal artery pseudoaneurysm is an uncommon disease. A 47-year-old man complained of recently developed gross hematuria and left flank pain. The initial laboratory study and radiographic evaluation revealed acute pyelonephritis. After the treatment with antibiotics, gross hematuria was resolved and the patient was discharged. However, he revisited with repeated gross hematuria and throbbing left flank pain. The renal angiography revealed left intra-renal arterial pseudoaneurysm. Angiographic embolization by glue injection was successfully performed. Thereafter, gross hematuria and flank pain were disappeared. We report a successful glue embolization of intra-renal artery pseudoaneurym associated with acute pyelonephritis.
