Proximal Extracapsular Tunneling: A Simple Technique for the Management of Impending Cylinder Erosion and Complications Related to Corporal Dilation

Abstract

Introduction: Impending cylinder erosion and floppy glans secondary to an undersized penile prosthesis are rare complications that can cause cosmetic deformity and patient discomfort. Aim: To demonstrate a technique for the management of impending cylinder erosion and floppy glans secondary to cylinder under-sizing. Methods: We retrospectively reviewed 6 patients who required the proximal extracapsular tunneling technique during penile prosthesis revision surgery. Main Outcome Measure: Main outcome was successful placement of a penile prosthesis with proper cylinder placement. Results: Mean patient age for these 6 patients was 71.2 years (64–86 y). After a mean follow-up of 6.6 months, all 6 patients who underwent this procedure had a functional penile prosthesis without evidence of recurrence. Conclusion: The proximal extracapsular tunneling technique is a simple approach performed through a single incision that can be used for proper cylinder replacement during penile prosthesis revision surgeries. It may be utilized for the management of impending cylinder erosion and other cases with coporal dilation-related complications in which the surgical pseudo-capsule has already formed around the implant. This technique can be safely performed without the need of a distal counter-incision on the penis. Clavell-Hernández J.
