027 Single-center, 7-year Experience of Inflatable Penile Prosthesis Revision Surgery

Abstract

Inflatable Penile Prosthesis (IPP) remains the mainstay for surgical management of erectile dysfunction (ED). Complications such as malfunction, infection and erosion oftentimes require explanation of the prosthesis. The primary aim was to determine the feasibility and efficacy profile of performing revision IPP operations. A single-center, retrospective review of all patients who underwent IPP re-implantation from 2008-2015 were included in our analysis. Age, BMI, original surgery date, etiology of explantation, and re-implantation surgical variables including operative duration, blood loss, hospital duration, and date of activation were recorded for each patient. Feasibility and efficacy were determined by comparing blood loss, hospital duration and date of activation to patients undergoing primary implantation. 57 patients with a mean age and BMI of 68 years and 29.3, respectively, underwent revision IPP placement between 2008 and 2015. 15% (9/57) of patients had a prior history of multiple (>2) IPP surgeries prior to revision surgery at our institution. The date of original implantation ranged from 1977 to 2014. The most common reason for revision was IPP malfunction (pump, reservoir or tubing leak, etc.) at 82.5% followed by infection at 12.3%, exchange from semi-rigid to three-piece IPP at 3.6%, and erosion at 1.8%. Revision surgery resulted in an average blood loss of 44.9, operative duration of 130.2 minutes, and hospital duration of 1.1 days. Time to activation of IPP was approximately 52.7 days.
