Purpose:
Low-intensity extracorporeal shock wave therapy (Li-ESWT) stimulate the angiogenesis to increase the blood flow during erection. Theoretically, the objective penile hemodynamic will be enhanced to match the results of erectile performance. So we perform a small scale study to assess penile hemodynamic before and after LI-ESWT in a group of patients with vasculogenic erectile dysfunction.
Materials and Methods:
Thirty-nine patients with mild to moderate ED underwent LI-ESWT. This was a single arm trial. All patients underwent penile Doppler ultrasonography by the same investigator at baseline and one month. We also record the IIEF-5 and EHS to investigate the improvement in objective hemodynamic results.
Results:
Thirty patients with ED underwent LiESWT for 6 treatment sessions in 6 weeks. The values of PSV and IIEF-5 before and after Li-ESWT showed significant improvement, but RI did not change significantly. The improvement of IIEF-5 did not correlate well with the PSV change. There was no difference in RI between the two groups with and without improvement in PSV. EHS and erectile angle has no significant difference after treatment in average.
Conclusions:
The present study confirms the beneficial effect of LI-ESWT on penile arterial perfusion, but no improvement on venous occlusion. The discrepancy between the IIEF-5 and PSV give us the space to explore the real mechanism of shock wave in the treatment of erectile dysfunction.
