[Penile prosthesis for erectile dysfunction in the neurological patient, indication, complications and satisfaction: Retrospective study on 27 patients].

INTRODUCTION

Penile prosthesis for erectile dysfunction in patients with spinal cord injury or multiple sclerosis is sometimes discussed after failure of drug or instrumental treatments (vacuum). The objective of this study was to evaluate the complications, evolution and patient satisfaction after the implantation of a penile prosthesis in the neurological patient.

MATERIALS AND METHODS

Multi-center retrospective study of 27 consecutive patients including 18 spinal cord injured patients and 9 patients with multiple sclerosis benefiting from the implantation of a penile prosthesis for erectile dysfunction purposes in two French centers between 2009 and 2019. Post-implantation complications, evolution of the use of the prosthesis and global patient satisfaction were evaluated using the standardized questionnaire Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) during a telephone call between March and May 2020.

RESULTS

The average age of implantation was 46.4 years (±12.74). The length of follow-up to date of call was 6.05 years (±2.86). 8/27 patients (29.6 %) had at least one complication of any Clavien-Dindo grade included 2 infection. 2/27 (7,4 %) patients had a mechanical prosthesis injury during follow-up. The patient's dexterity with inflation of the prosthesis was perfect in 85 % of cases, and 75 % for deflation. The satisfaction rate for prosthesis use at the time of the call was 75.36/100pts for the patient and 66.88/100pts for the partner.

CONCLUSION

This study found an increased rate of prothesis infection compared to the general population in the neurologic patient, but patient and partner satisfaction remain sustainable after more than 5 years of implantation. Dexterity was maintained over the long term, demonstrating a good selection of indications. These data invite to favorably consider the installation of a penile prosthesis in neurological patients who have failed first-line treatments.
