Abstract

BACKGROUND:

This randomized clinical trial (October 2012-December 2013) compared extracorporeal shock wave therapy (ESWT) and a vacuum erectile device (VED) for management of erectile dysfunction (ED).

METHODS:

Consecutive Chinese patients (20-55 years) with ED, abnormal nocturnal penile tumescence and rigidity (NPTR), and international index of erectile function-5 items (IIEF-5) score <22 were randomized to receive ESWT or VED (twice weekly, 4 weeks). Primary outcomes were treatment efficacy and success rate 4 weeks after completion of therapy. Secondary outcomes included changes in IIEF-5 score, sex encounter profile (SEP) score, erection hardness score (EHS) and NPTR assessments 4 weeks post-therapy. All enrolled patients (n = 30 per group) completed the study. At baseline, age, IIEF-5 score, SEP score, EHS, and NPTR assessments were similar between groups.

RESULTS:

Four weeks post-therapy, IIEF-5 score increased in the ESWT (15.03 ± 3.00 vs. 11.60 ± 2.28) and VED (15.10 ± 3.06 vs. 11.53 ± 2.27) groups, as did SEP score, EHS, and NPTR measures (all P < .05). Efficacy in the ESWT and VED groups was excellent in 10% and 13.3%, respectively, and moderate in 63.3% and 53.3%, respectively. Treatment success rate in the ESWT and VED groups was 73.3% and 67.7%, respectively.

CONCLUSION:

VED use and ESWT have comparable efficacies in the treatment of ED in Chinese patients.
