Low-intensity Shockwaves Therapy + Tadalafil 5mg for the Treatment of Severe Erectile Dysfunction

This is a randomized, double‐blind, sham‐controlled, 3 parallel arms, clinical trial. All patients will be PDE5I users or ex‐users. After 1 month wash‐out period, ED patients will be screened, in order to randomize 51 men with vasculogenic ED. Patients will be randomized in 3 groups (17 subjects in each group) to receive shockwave treatments (12 sessions for all subjects, 5000 shockwaves at each session, at energy level 7), three times a week (total of 4 weeks) without treatment interval. One group will be sham‐control at energy level 7 whereas 2 groups will receive active treatment.Three identical standard probes (probes A, B, C) will be used for the study, 2 of them active and one sham. Starting at first LiST session and finishing at the final week of LiST sessions, subjects will receive Tadalafil 5mg for 4 weeks daily. Total treatment period = 4 weeks. The IIEF‐ED domain will be evaluated at Visit 1 and, consequently, at baseline and all follow up visits together with the SEP diaries.
