[Low-intensity extracorporeal shockwave therapy for Peyronie's disease: A preliminary study of 32 cases].Zhonghua Nan Ke Xue. 2018 Apr; 24(4):340-344.ZN
To investigate the clinical effect of low-intensity extracorporeal shockwave therapy (LI-ESWT) on Peyronie's disease.
From October 2016 to December 2017, we treated 32 cases of Peyronie's disease by LI-ESWT, with the therapeutic index of 0.09 mJ/mm2 and a pulse frequency of 120 beats/min. Each plaque was approached from two angles, each angle with a shockwave output of 900 times, and the larger ones from three points, each with an output of 600 times in addition to 300 times from the distal and proximal ends of the plaque, respectively. All the patients received 12 courses of treatment (2 courses a week) with a break of 3 weeks between the 1st and 2nd 6 courses. Then we observed the plague size and penile curvature of the patients, obtained their scores on the Visual Analogue Scale (VAS) and International Index of Erectile Function 5 (IIEF-5), and recorded their adverse reactions.
The plagues were softened or diminished in different degrees in 9 of the 32 cases and erectile pain was alleviated in 15 cases after treatment. Penile curvature at erection, however, showed no significant improvement. The IIEF-5 scores were increased in 18 of the patients complicated with varied degrees of erectile dysfunction after LI-ESWT. No obvious complications were observed in any of the patients.
Low-intensity extracorporeal shockwave therapy has a certain effect on Peyronie's disease by relieving plague-induced pain and improving the patient's penile erection and quality of life.
