Satisfaction rate at 1‐year follow‐up in patients treated with penile implants: data from the multicentre prospective registry <scp>INSIST</scp> ‐ <scp>ED</scp>

Abstract

OBJECTIVES: To investigate scores and predictors of patient satisfaction at 1 year after penile prosthesis implantation (PPI) using the validated Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) questionnaire. PATIENTS AND METHODS: Analyses were performed for 142 patients prospectively included in the national multicentre registry Italian Nationwide Systematic Inventarization of Surgical Treatment for Erectile Dysfunction (INSIST-ED), which provided 1-year follow-up data. Postoperative patient satisfaction was assessed using the validated QoLSPP tool. Linear logistic regression analyses assessed predictors of QoLSPP total and single domain scores, including age at surgery, erectile dysfunction aetiology, type of prosthesis, surgical approach, surgeon experience and complications. Locally weighted regression methods were used to explore the relationship between surgeon experience and QoLSPP scores. RESULTS: Overall, high median functional, relational, social, personal and total QoLSPP scores were reported at 1 year after PPI. Patients implanted with hydraulic devices had higher functional (23 vs 21.5; P = 0.01) and total scores (68 vs 65.5; P = 0.03) than those with a malleable prosthesis. Surgeon experience emerged as the only independent predictor of higher satisfaction scores, depicting a non-linear association with both QoLSPP total and single domain scores (all P < 0.03). Data suggested that the higher the number of procedures per year, the greater the satisfaction scores, reaching a plateau after l5 procedures/year. CONCLUSIONS: This study reports high functional and patient satisfaction scores at 1 year after PPI surgery using a dedicated tool for the first time. Better outcomes should be expected for patients treated by surgeons with greater experience.
