Management of Tunica Albuginea Disruption Secondary to Malleable Penile Implant Fracture: Insights into Etiology and Surgical Approach

Abstract Background The tunica albuginea is a key anatomical structure supporting penile implants. Several factors can lead to anatomical penile defects, contributing to penile prosthesis malfunction.The aim is to describe the consequences of malleable penile implant fractures, their contribution to tunica albuginea defects, and management outcomes. Results This study included three patients with malleable penile implant malfunction secondary to device fracture. Two patients underwent PC and device replacement. One patient experienced persistent device instability despite device replacement without PC but later underwent corrective PC. The mean age at revision was 71.3 years. All patients achieved device stability and reported satisfaction after PC and device replacement, with a median follow-up of 28 months. Conclusions Malleable penile device fractures are extremely rare. They can cause tunica albuginea disruption and tears, compromising penile penetration and device stability. Device replacement combined with PC is an essential component of surgical management.
