Renal Artery Pseudoaneurysm Following a Laparoscopic Partial Nephrectomy: Hemorrhage after a Successful Embolization

Laparoscopic partial nephrectomy is increasingly practiced by urologists, and its technique isconstantly improving. Recently, Simforoosh and colleagues reported a simplified technique for performing partial nephrectomy. (1) Renal artery pseudoaneurysm is an uncommon complication after laparoscopic partial nephrectomy. (2) Few cases have been reportedso far with this problem, and all of the reported patients who had undergone successful angioembolization were free from hematuria.(3,4) We present a patient who had a massive hematuria and severe drop of the blood pressure in spite of her successful embolization of renal artery pseudoaneurysm after laparoscopic partial nephrectomy.
