Extracorporeal Shock Wave Therapy in Peyronie's Disease: Clinical Efficacy and Safety from a Single-Arm Observational Study.

PURPOSE: In this study, we aimed to determine the role of extracorporeal shockwave therapy (ESWT) in the management of Peyronie's disease (PD).

MATERIALS AND

METHODS

A total of 325 patients suffering from PD were enrolled in this single-arm clinical study. All patients were received ESWT using a schedule of 1 treatment/wk. Penile curvature was measured by a goniometer after intracavernosal drug-induced erection using Alprostadil. Plaque size was measured with a ruler and sexual function assessed by the international index of erectile function (IIEF)-15 score. Severity of erectile dysfunction was classified as severe (IIEF-15 ≤10), moderate (IIEF-15 between 11 and 16), or mild (IIEF-15 between 17 and 25). Results were evaluated at baseline and 3 months after the treatment.

RESULTS

All the patients completed the study protocol. Median age was 59.0 years (55.0-64.0 years). After treatment, the median (interquartile range, IQR) plaque size reduced from 1.78 cm² (1.43-2.17 cm²) to 1.53 cm² (1.31-1.96 cm²) (p<0.001); the median (IQR) penile length in erection increased from 13.0 cm (12.0-14.0 cm) to 14 cm (13.0-15.0 cm) (p<0.001) and the median (IQR) penile curvature from 30.4° (22.2°-35.4°) to 25.0° (20.2°-30.4°) (p<0.001). We also observed a decrease in pain assessed by visual analogue scale (7 vs. 3; p<0.001), an improvement in each of the IIEF sub-domains (p<0.001) and an improvement in all three PD questionnaire domains (p<0.001).

CONCLUSIONS

Based on our findings, ESWT could be considered a safe and efficient minimally invasive option for the management of the patients suffering from PD.
