title: Case report: late recurrent hematuria following laparoscopic radical prostatectomy may predict internal pudendal artery pseudoaneurysm and arteriovenous fistula.
abstract: We report two cases of a pseudoaneurysm of the internal pudendal artery with arteriovenous fistula after extraperitoneal laparoscopic radical prostatectomy. The clinical presentation was delayed recurrent hematuria and urinary retention that necessitated bladder clot evacuation. Subsequent arteriography detected the vascular abnormality and a superselective embolization was performed. Hematuria was no longer observed, and the quality of penile erection remains unchanged in both patients.
