OBJECTIVE: To make a preliminary investigation on the safety and efficacy of focused low-intensity extracorporeal shock wave therapy (LI-ESWT) in the treatment of erectile dysfunction (ED).
METHODS: We treated 32 ED patients by focused LI-ESWT with the device of Medispec's ED1000. Before and at 4 and 12 weeks after treatment, we evaluated the erectile function of the patients using the International Index of Erectile Function-erectile function domain (IIEF-EF), Erection Hardness Score (EHS), Sexual Encounter Profile questions 2 and 3 (SEP2 and SEP3), and Global Assessment Questionnaire questions 1 and 2 (GAQ1 and GAQ2), and recorded the incidence rate of adverse events.
RESULTS: The patients averaged 30.69 years of age. Compared with the baseline, the mean IIEF-EF score of the patients was significantly increased at 4 and 12 weeks after LI-ESWT (14.94 vs 20.97 and 21.47, P <0.01), and so were the EHS (1.75 vs 2.66 and 2.56, P <0.01) and the "Yes" answers to SEP2 (21.88% vs 68.75% and 71.88%), SEP3 (0 vs 43.75% and 56.25%), GAQ1 (NA vs 81.25% and 71.88%) and GAQ2 (NA vs 65.63% and 68.75%). The total effectiveness rates at 4 weeks and 12 weeks were 75% and 71.88% respectively. One of the patients felt penile shaft pain with mild ecchymosis after LI-ESWT but was recovered without special treatment a week later.
CONCLUSIONS: LI-ESWT can significantly improve the erectile function of ED patients with no obvious adverse effects within 12 weeks after treatment.
