Radial Shockwave Therapy for Erectile Dysfunction

Objective: To evaluate the efficacy and safety of radial shock waves for the treatment of erectile dysfunction [ED]. Patients and methods: Randomized, double-blind clinical trial. The study will include patients of legal age with diagnosis of ED and score on the International Index of Erectile Function [IIEF-EF] scale between 11 and 21 points, who voluntarily decide to participate and sign the informed consent. Patients with bladder cancer, prostate cancer or active colon, ED of psychological origin, any psychiatric disorder, spinal cord injury, clinical suspicion of hypogonadism (score on the Aging Males' Symptoms scale greater than 36), infections or active lesions of the penis or pubic area, ED secondary to treatment with medications (antiandrogenic therapy, use of corticosteroids, anti-Parkinson's, antipsychotics), radical prostatectomy or other radical pelvic surgery, history of pelvic radiotherapy, penile implantation, or endocrine diseases that occur with ED (acromegaly, gigantism, Addison's disease, hyperprolactinemia, androgenic deficiency), sickle cell anemia, and anticoagulated patients will be excluded. Patients will be randomly assigned to one of the following treatment arms: * Arm 1 (Standard treatment (oral sildenafil) + Radial wave therapy) * Arm 2 (Standard treatment (oral sildenafil) + Placebo therapy) Measurements will be made of the Erection Hardness Score [EHS] and IIEF-EF scale scores, of the use of medication and of the possible adverse events of the therapy, at the beginning and end of the treatment, and one month after the therapies are finished.
