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.

I found it in Pubmed: "The article, “Comparison of the effects of extracorporeal shock wave therapy and a vacuum erectile device on penile erectile dysfunction: a randomized clinical trial”[1], which appeared in Volume 96, Issue 44 of Medicine, is being retracted for plagiarized data previously published in another study."

This retraction is published in: Medicine (Baltimore). 2018 Mar; 97(12): e0262. Published online 2018 Mar 23. doi: 10.1097/MD.0000000000010262

Could you say me what is the original study?

Best regards

There is currently a great interest and research activity in how to treat patients with ED. Accordingly there has been a dramatic improvement in the therapeutic options during past decades. The major progress came with the introduction of phosphodiesterase-5 inhibitors (PDE5i; e.g. Viagra). Attributable to insufficient effects in a certain proportion of PDE5i-treated ED patients, other alternatives were invented. This article addressed the use of ESWT and VED (vacuum erectile device).

The purpose of this randomized study was to compare these two methods. Both ESWT and VED-treatment were carried out with Chinese devices. Follow-up after 4 weeks showed a very similar outcome.

Inasmuch as ESWT in different studies is carried out with different strategies, it should be noted that the effect achieved in this report was obtained by delivery of 1500 sw distributed on five treatment points twice a week during four weeks.

Two questions arise:
1. Would a later follow-up have been of interest when considering the different physiological mechanisms? My own assumption is that the effect of ESWT would be later than that of VED-treatment.
2. How would a combined treatment with PDE5i and ESWT turn out?
