Renal artery pseudoaneurysm after laparoscopic partial nephrectomy for renal cell carcinoma in a solitary kidney.

Renal artery pseudoaneurysms are a well-documented complication following trauma or percutaneous urological procedures, but are rare after partial nephrectomy. We present the case of a 34-year-old woman who, after undergoing a left nephrectomy in childhood due to Wilms' tumor, had a pseudoaneurysm in a solitary kidney after laparoscopic right partial nephrectomy with extraperitoneal approach for a renal cell carcinoma. The segmental renal artery feeding the pseudoaneurysm was embolized with coils without significant loss of residual renal function.
