Summary

This study tests whether low-intensity shock wave therapy, a non-surgical treatment applied over the lower abdomen, can ease overactive bladder symptoms in women who haven't found relief from standard treatments. Forty women will be randomly assigned to receive either the real therapy or a sham version once a week for six weeks. Researchers will compare symptom scores and quality of life between the groups to see if the therapy offers a meaningful benefit.

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) delivered via the PiezoWave 2 device
What this could lead to
If effective, this non-surgical therapy could offer a new option for women with overactive bladder symptoms that don't improve with standard care.
What could go wrong
This is a small early-stage trial, and the sham comparison means the real benefit is uncertain. The therapy may not outperform placebo, and individual results can vary.
