Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether delivering tiny electrical bursts to a nerve bundle in the lower back can reduce pain in women with bladder pain syndrome. Five women will receive the procedure once and be followed for six months. Researchers will measure pain, bladder symptoms, mood, and sexual function. Because it is a very small, early study without a placebo group, results will be preliminary.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
pulsed radiofrequency ablation
What this could lead to
If it works, this could point toward a new, non-drug option for women with bladder pain syndrome.
What could go wrong
This is a very small, early case series with only 5 participants and no comparison group. The procedure may not provide lasting pain relief, and there are risks from needle insertion near the spine.
