Medical Hypothesis: Loss of the Endocrine Function of the Prostate Is Important to the Pathophysiology of Postprostatectomy Erectile Dysfunction

Current trends in erectile rehabilitation after radical prostatectomy: Results from a worldwide survey

We aimed to analyse the current trend of erectile rehabilitation (ER) following radical prostatectomy (RP) using a dedicated survey. An online survey was developed between July and September 2020, aiming to evaluate the ER protocols after RP in daily practice among urologists, andrologists, sexual medicine specialists and residents. We investigated demographics data, type of RP performed, and type, schedule, timing and duration of ER protocols. In total, 518 responders from 52 countries completed the survey. Surgical techniques reported were: 38.9% open, 22.9% laparoscopic and 38.2% robot-assisted RP. 33% of the responders begin ER at the catheter removal, 22% 1 month after surgery and 15% before surgery. Phosphodiesterase inhibitors were the most used medication as first-line treatment (99.4%). Tadalafil 20 mg was the most prescribed, and used daily in 48.2% of the cases, and 2-3 times/week in 46%. Intra-cavernosal injection of prostaglandin E1 was the second most common prescribed monotherapy (67.9%) followed by the association of phosphodiesterase inhibitors and vacuum-erection device (29.6%). The duration of ER was <6 months in 16.2%, between 6 and 11 months in 39%, between 12 and 18 months in 31.9%, between 19-24 months in 9.2% and >24 months in 3.7%. This study showed that the approach to ER after RP was inhomogeneous. International guidelines are urgently needed to standardise ER protocols.
