An outcomes analysis of over 200 revision surgeries for penile prosthesis implantation: a multicenter study.
(Journal Article;Multicenter Study)
INTRODUCTION: Inflatable penile prosthesis (IPP) implantation is a well-established treatment for medically refractory erectile dysfunction, with long-term reliability. Overall survival is 96% at 5 years and 60% at 15 years for primary (virgin) implantation. AIM: The aim of this study was to explore factors associated with success and complications of IPP revision surgery in a multicenter study. MAIN OUTCOME MEASURES: Reasons for revision including mechanical issues, patient dissatisfaction, corporal deformity, and supersonic transport (SST) deformity were recorded. METHODS: At four institutions, 214 clinically uninfected IPP revisions were performed between November 2000 and November 2007. Data were incomplete for 28 cases (14%). Failure-free survival was estimated using Kaplan-Meier's Meier product limit method. RESULTS: The majority of revisions were secondary to mechanical failure (N = 109; 65%) and combined erosion or infection (N = 17 + 15 = 32; 19%). Sixteen percent (N = 26) were carried out on functional uninfected prostheses secondary to patient dissatisfaction (N = 9), SST deformity (N = 10), scrotal hematoma (N = 2), or upsize revision because of corporal fibrosis (N = 5). Average age at revision was 66 years. Mean follow-up time was 55.7 months. In this study, 12 individuals required a secondary revision procedure or suffered a complication. Despite prior reports of high infection rates with revision surgery, only 5.7% of clinically uninfected and noneroded prostheses were complicated by infection or impending extrusion/erosion, following a revision washout protocol. Overall, 93% of cases were successfully revised, providing functioning IPPs. CONCLUSIONS: For this study population, component exchange followed by revision washout showed a low incidence of infection and subsequent mechanical failure.
