Satisfaction and surgical outcomes in patients undergoing penile prosthesis implantation for drug-refractory erectile dysfunction: mid-term results in a single center French cohort.

Introduction: To investigate the mid-term results of penile prosthesis (PP) implantation in patients with erectile dysfunction (ED) from a "real-life" historic cohort in a French academic center.

Materials And Methods: All patients receiving an inflatable PP between 2004 and 2014 in our institution were included in this study. ED was assessed preoperatively using the IEEF-5 questionnaire. Postoperative satisfaction with the PP was assessed using the EDITS questionnaire at each follow up visit. Postoperative complications were classed according to the Clavien classification. Surgical and functional outcomes were recorded prospectively.

Results: Seventy-six men received a PP during the 10 year study period. Median (IQR) age was 62 (58-69) years. The main causes of ED were radical prostatectomy (n = 40; 53%) and diabetes mellitus (n = 28; 36.8%). Five patients (6.6%) had a non-functioning PP in place requiring complete substitution or a previous penile implant which had already been removed at the time of surgery. Sixty-nine (90.8%) patients received an AMS 700 CX device and seven (9.2%) a Coloplast Titan. The surgical approach was penoscrotal in 45 (59.2%) and infrapubic in 31 (40.8%). Intraoperative complications occurred in four (5%) patients, without compromising the intervention. Postoperative complications occurred in 27 (35.5%) patients: 17 (22%) were Clavien I-II and 10 (15%) Clavien III. All major complications resulted in prosthesis removal (n = 9; 11.8%) or revision (n = 1; 1.3%). Median (IQR) follow up was 43 (34-55) months. At the end of follow up, 70 (92.1%) patients had a functional implant. Fifty-four (71.1%) patients were satisfied with the device at the 6 month follow up visit and beyond. Early satisfaction (at 3 months) was reported by 44 (57.9%) patients. A previous PP was the only significant risk factor for prosthesis removal (p = 0.001).

Conclusion: PP implantation is a safe and satisfactory treatment for ED. However, patient selection remains crucial in determining the post-surgical success of this procedure.
