In plain words

What the trial is, and whether it could suit you

The goal of this clinical trial is to assess the efficacy and safety of linear piezoelectric Li-SWT for erectile dysfunction patients who have poor treatment respond from PDE5i oral treatment. Participants will be randomised to either receive 4 cycles, once per week, of Li-SWT treatment on the penis or the Sham group, where the treatment appears to be identical but the shockwave machine is deactivated. Investigators will compare the before and after treatment erectile function using the IIEF questionnaire of the two groups 1 month after treatment to assess the treatment outcome. After that, the Sham group patient would be offered to receive compensatory Li-SWT treatment and their post treatment response will be assessed. All the patients completing the Li-SWT treatment will be followed up at 6 and 12 months to assess the efficacy and adverse events.
