In a nutshell
This study analyzed the results of 7 studies to examine the effectiveness of low-intensity shock wave therapy (LIST) for erectile dysfunction. Authors concluded that LIST resulted in a significant improvement in erectile function.
Some background
Low-intensity shock wave therapy (LIST) has recently been introduced as a new therapeutic approach for erectile dysfunction. LIST allows for an increase in penile blood flow by delivering low-intensity (non-harmful) shock waves to the penis. These are believed to stimulate the formation of new blood vessels, which is important in achieving an erection. LIST is an alternative treatment option for men who do not respond to, or tolerate, drug therapy with phosphodiesterase-5 inhibitors, such as sildenafil (Viagra). More high-quality studies are needed to examine its effectiveness for erectile dysfunction.
Methods & findings
The aim of this study was to examine the effectiveness of LIST in treating erectile dysfunction.
The results of 7 separate studies were pooled into a single analysis. A total of 607 men with erectile dysfunction were included. Men were randomly assigned to be treated with either LIST or with a placebo procedure involving no active treatment. Changes in erectile function were measured using a questionnaire, where scores ranged from 5 (severe erectile dysfunction) to 25 (no erectile dysfunction). Patients were followed for an average of 19.8 months.
Erectile function significantly improved among men treated with LIST compared to those receiving the placebo treatment. The average erectile function score before treatment was 9.2 (considered moderate erectile dysfunction). Men treated with LIST improved by an average of 6.4 points. In contrast, men in the placebo group improved by 1.65 points.
The bottom line
Authors concluded that LIST significantly improved erectile function.
