Sound waves for endometriosis: do the benefits last?
NCT ID NCT07179419
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 140 patients who previously received High-Intensity Focused Ultrasound (HIFU) for rectal endometriosis. Researchers want to see if the treatment's benefits—like pain relief and better quality of life—hold up over the long term. Participants fill out online questionnaires to track their health years after the procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- High-Intensity Focused Ultrasound (HIFU)
- What this could lead to
- If successful, this could show that HIFU offers a non-invasive, long-lasting option to manage rectal endometriosis symptoms and improve quality of life.
- What could go wrong
- This is a follow-up study without a control group, so results may not prove HIFU is better than other treatments. Long-term benefits are uncertain, and some patients may still need additional therapy.
