Clinical outcomes and patient satisfaction rates among elderly male aged ≥75 years with inflatable penile prosthesis implant for medically refractory erectile dysfunction

The purpose of the study is to assess the clinical outcomes and patient satisfaction rate between men aged under and over 75 years who underwent inflatable penile prosthesis (IPP) implantation. A retrospective review of clinical database and follow-up independent telephone survey was undertaken in all men who underwent first-time IPP implantation between January 2006 and November 2010. Patient demographics, surgical outcomes, and patient satisfaction rate using Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores were recorded. A total of 216 first-time IPP were implanted. Of these, 30 patients were aged >= 75 years. In men aged >= 75 years, 3 patients had IPP revision surgery for mechanical malfunction (average 18.6 months; 12-24 months). While the 2-year Kaplan-Meier estimates of mechanical survival showed better outcome in men aged >= 75 years than men aged < 75 years (95 vs. 92 %; p = 0.38), there was no difference in the IPP mechanical survival between the 2 groups at 3 years follow-up. There were no statistically significant differences in the ease of IPP use, and EDITS scores among the two groups. The majority of men were satisfied and would recommend the IPP surgery to other men. Men aged >= 75 years reported satisfactory outcome with IPP surgery with no statistical significant difference identified across device survival and satisfaction rates compared to men aged < 75 years.
