Prostatic artery pseudoaneurysm presenting with hematuria following robot-assisted radical prostatectomy: a case report.

Pseudoaneurysm following robot-assisted radical prostatectomy is an infrequent complication. We present a rare case of gross hematuria caused by a pseudoaneurysm. A 76-year-old man was diagnosed with prostatic adenocarcinoma and underwent robot-assisted radical prostatectomy. On postoperative day 9, he presented with gross hematuria and clot retention, accompanied by anemia. Bladder irrigation was performed, resulting in improvement of the hematuria. Contrast-enhanced computed tomography revealed a pseudoaneurysm. As his hematuria improved and his vital signs remained stable, angiography was performed on postoperative day 10. This revealed a pseudoaneurysm arising from the prostatic artery, which was successfully treated with transcatheter arterial embolism. His postoperative course was uneventful, and he was discharged on postoperative day 14. Pseudoaneurysm after robot-assisted prostatectomy is rare but important to consider in patients with delayed hematuria. Early diagnosis and embolization can lead to good outcomes.
