Detection of renal artery pseudo-aneurysm six months after robotic assisted partial nephrectomy in a patient whose only complaint was flank pain.

Abstract Renal artery pseudoaneurysm (RAP) is a potentially life-threatening complication after partial nephrectomy (PN). Studies suggests that most cases present within 15 days post operatively with one of three classic symptoms: gross hematuria, flank pain and/or anemia. However, there are a limited number of reports in the literature regarding delayed RAP (≥four months). To the best of our knowledge we report the first case of RAP six months following robotic-assisted PN.
