Efficacy of Low-Intensity Extra Corporal Shockwave Therapy (LI-ESWT) In Patients With Erectile Dysfunction

Abstract

Objective: Erectile dysfunction (ED) is a common cause of sexual disorders in men with limited treatment options. This study aimed to determine the efficacy of low-intensity extra corporal shockwave therapy (LI-ESWT) in patients suffering from ED.
 Materials and methods: A single-group, pre-test, and post-test pre-experimental study were conducted. Thirty-one ED patients were prospectively selected according to the eligibility criteria. In each session, 3000 shocks were applied at 5 points over the penis. Eight sessions were delivered in total with a 2–3-day interval. The patient’s condition was assessed using the International Index of Electric Function (IIEF-5) questionnaire at baseline and one month after the last treatment session. Paired t-test was used to determine the difference between the pre-test and post-test.
 Results: Mean age of the patients was 44.6 (± 14.70) ranging from 25 to 78 years. The majority of them were married (83.9%) and service providers (51.6%). We have also found 51.6% overweight, 9.7% obese, 48.4% diabetic, 45.2% hypertensive, 12.9% with enlarged prostate, 45.2% smoker, 25.8% alcoholic, and 71% with sleep disturbances. During the pre-test, 9.7% had severe ED and 51.6% had moderate ED. After the treatment, no patients were found with severe ED, and few of them had moderate ED (9.7%). The mean difference in IIEF-5 score during the pre-test and post-test was statistically significant (p= < 0.001).
 Conclusion: The study showed efficacy of LI-ESWT in a subset of patients with ED. Future studies with larger sample size, placebo group, and longer follow-up periods are recommended.
