Is low-intensity shockwave therapy for erectile dysfunction a durable treatment option?-long-term outcomes of a randomized sham-controlled trial.
Background: Low-intensity shockwave therapy (LiSWT) is an emerging non-invasive and restorative therapy for erectile dysfunction (ED) with demonstrated efficacy and few adverse events. Although LiSWT has been shown to improve erectile function amongst men with ED, few studies have examined its long-term durability. We present the long-term results of a randomized controlled trial (RCT) assessing erectile function after LiSWT.
Methods: A total of 30 patients with baseline ED seen at the University of Virginia were randomized to LiSWT or sham treatment. Patients in the sham group crossed over at 1 month and were unblinded. After initial trial completion, patients enrolled in the long-term outcome study were considered one combined cohort. Patients were treated twice weekly for 3 consecutive weeks with a Storz® Duolith™ device delivering 3,000 shockwaves at 0.1 mJ/mm2 to the distal penis, the base of the penis, and the crura. Primary outcomes were changes in Sexual Health Inventory for Men (SHIM) and Erection Hardness Score (EHS) from baseline (3 months pre-treatment) up to 36 months post-treatment. Changes in SHIM and EHS scores were evaluated using linear mixed effects models. Patient satisfaction was assessed with the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) index.
Results: The mean baseline SHIM score was 10.8±0.94. At 12-, 24-, and 36-month assessment following treatment, the mean SHIM scores were 15.6±1.27 (P<0.001), 15.0±1.14 (P<0.001), and 12.2±1.43 (P=0.31). The mean baseline EHS score was 1.87±0.17. At 12-, 24-, and 36-month assessment following treatment, the mean EHSs were 2.70±0.24 (P<0.001), 2.66±0.21 (P<0.001), and 2.29±0.26 (P=0.10). The median [interquartile range (IQR)] EDITS score was 48.9 (22.7, 74.4), indicating moderate satisfaction with LiSWT. There were no adverse events recorded.
Conclusions: Our analysis demonstrates sustained long-term improvement in erectile function after LiSWT for a heterogeneous cohort. While limited by population size, the results suggest durable improvement in erectile function for the first 2 years with a peak treatment effect at 1 year. Treatment effect appears to decline between 2 and 3 years.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
