Dorsal Penile Artery Avulsion After Collagenase Clostridium histolyticum (Xiaflex) for Peyronie’s Disease: A Case Report

Collagenase Clostridium histolyticum (CCH) is frequently used as first-line therapy for patients with Peyronie’s disease. It was United States Food and Drug Administration approved in 2013 and since then, has been widely accepted as a safe and effective treatment option with most adverse effects being minor and amenable to conservative management. We report an unusual and previously unreported complication after CCH (Xiaflex) injection: avulsion of a dorsal penile artery, which required surgical exploration and ligation. This article seeks to inform urologists about an unexpected complication that should be considered in the differential diagnosis for severe penile hematoma after CCH injection and discusses our strategy for surgical management.
