Brief Summary

This study is a prospective, randomized, single-blinded, cross-over trial to investigate the efficacy of low-intensity extracorporeal shockwave therapy in the treatment of erectile dysfunction (ED). We will enroll 60 subjects (International Index of Erectile Function Questionnaires, 5 ≦ IIEF-5 ≦ 21). 30 subjects receive ESWT (LM-IASO, Litemed Co., Taiwan) for 6 courses in 3 weeks (0.05mJ/mm2, 3000 pulses) and 30 subjects receive Sham therapy for 3 weeks (the machine turning on but the energy is zero). After 3 weeks, the two groups are cross over. The primary outcome is the 4th week change from baseline for IIEF-5 score. Secondary outcomes are the 8th week change from baseline for IIEF-5 score, EHS, QoL; AEs. The between-group relationships of baseline and 4-week data were evaluated by using the Student's t-test or Mann-Whitney U-test where appropriate. Multiple linear regression was carried out to test the variables associated with treatment outcome. P-values \< 0.05 were considered statistically significant.

Outcome Measures

Primary Outcomes (1)

  • IIEF-5 score

    the 4th week and the 8th week change from baseline for IIEF-5 score change from baseline for IIEF-5 score. The IIEF-5 Questionnaire Over the past 6 months: 1. How do you rate your confidence that you could get and keep an erection? (1-5) 2. When you had erections with sexual stimulation, how often were your erections hard enough for penetration? (1-5) 3. During sexual intercourse, how often were you able to maintain your erection after you had penetrated your partner? (1-5) 4. During sexual intercourse, how difficult was it to maintain your erection to completion of intercourse? (1-5) 5. When you attempted sexual intercourse, how often was it satisfactory for you? (1-5) Total Score: 1-7: Severe ED 8-11: Moderate ED 12-16: Mild-moderate ED 17-21: Mild ED 22-25: No ED

    the 4th week and the 8th week

Secondary Outcomes (3)

  • Penile Doppler Ultrasound (PDU)

    the 4th week and the 8th week

  • EHS(Erection Hardness Score)

    the 4th week and the 8th week

  • QoL: questionnaire

    the 4th week and the 8th week

Study Arms (2)

1

EXPERIMENTAL

30 subjects receive ESWT (LM-IASO, Litemed Co., Taiwan) for 6 courses in 3 weeks (0.05mJ/mm2, 3000 pulses). Thereafter, the two groups are cross over.

Device: low energy extracorporeal shockwave therapy

2

SHAM COMPARATOR

30 subjects receive Sham therapy for 3 weeks (the machine turning on but the energy is zero). Thereafter, the two groups are cross over.

Device: low energy extracorporeal shockwave therapy

Interventions

Low-intensity extracorporeal shockwave therapy (LI-ESWT) was proved to be useful in various medical conditions; for example, neovascularization in myocardial ischemia, nonhealing wounds, ED and chronic pelvic pain syndrome
