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: All patients underwent malleable device surgery were reviwed retrospectively in our center. We included three patients with malleable penile implant disruption. Two patients underwent concomitant plication corporoplasty (PC) with device replacemen and one patient with device replacement only that showed intact tunica albuginea. The mean age at revision was 71.3 years. All patients achieved device stability and reported successful vaginal penetartion after PC and device replacement, with a median follow-up of 28 months.

Conclusions: Malleable penile device fractures are extremely rare findings. They can cause tunica albuginea disruption and tears, compromising penile penetration and device stability. Device replacement combined with PC is an essential component of successful vaginal pentration.
