NCT ID NCT07460167
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested low-intensity shock wave therapy (LiSWT) in 25 men with erectile dysfunction after a pelvic fracture and urethral injury. The treatment uses a device that delivers gentle shock waves to the penis to improve blood flow. Researchers measured changes in penile blood flow and erectile function scores over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- low-intensity shock wave therapy (LiSWT) device
- What this could lead to
- If it works, this could offer a non-drug treatment option for erectile dysfunction after pelvic injury.
- What could go wrong
- This is a very small pilot study with only 25 participants and no control group. Results may not apply to everyone, and the therapy may not work for all.

Exclusion Criteria: * Previous hypospadias surgery. * Previous surgery for congenital curvature or Peyronie's disease. * Previous pelvic irradiation therapy. * Known grave psychiatric disorder. * Haemophilia or any other clotting disorder that causes bleeding diathesis. * Use of medication to increase erectile function, such as phosphodiesterase type 5 inhibitors and intracavernous injections, during the study. * Other causes of erectile dysfunction either physical causes as diabetes mellitus, hypertension, cardiovascular disease \& emotional causes. * Any condition or situation that, in the investigator's opinion, puts the patient at significant risk, could confound the study results, or could interfere significantly with the patient's participation in the study.
