Sound waves vs. radiation damage: new hope for bladder pain?
NCT ID NCT07016451
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed early-phase trial tested whether low-intensity shockwave therapy (Li-ESWT) can ease symptoms of radiation cystitis, a painful bladder condition from pelvic radiation. Twenty-five adults who had radiation at least six months prior were enrolled. The study compared shockwave treatment to standard medications, tracking changes in urinary symptoms and bladder inflammation markers.
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 extracorporeal shock wave therapy (Li-ESWT)
- What this could lead to
- If it works, this could offer a new, non-drug option to ease bladder pain and urinary symptoms caused by past radiation therapy.
- What could go wrong
- This is a very early, small trial with only 25 people. The results may not apply to everyone, and the treatment might not work better than standard medications.
