Case of renal arterial pseudoaneurysm after laparoscopic partial nephrectomy

A 41 year-old man with a history of diabetes mellitus underwent computed tomography for screening on August 2007. The CT revealed an enhancing 3.0 cm mass in the middle pole of the left kidney. We diagnosed as renal cancer, clinical stage T1aN0M0. Then he underwent laparoscopic left partial nephrectomy. The pathological result was renal cell carcinoma, G2 > G1, pT1a. On post operative day 12, he appeared a gross hematuria and dysuria, then he was rehospitalized due to drop of hemoglobin and bladder tamponade. Enhanced CT showed left renal artery pseudoaneurysm. He underwent selective coil embolization of left renal artery pseudoaneurysm. After that he repeated gross hematuria, and appeared bladder tamponade again. On POD 65 he underwent selective coil embolization again. Since then the patient recovered uneventfully.
