Comparing TENS and PTNS for treating overactive bladder

INvestigation of TENS Efficacy Versus Posterior Tibial Nerve Stimulation for Overactive Bladder

Not applicable Interventional University of New Mexico · NCT05309993

This study is testing whether a new electrical nerve treatment is just as good as a different nerve treatment for helping women with overactive bladder feel better.

What this trial studies

This research aims to evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) compared to percutaneous tibial nerve stimulation (PTNS) in improving the quality of life for women suffering from idiopathic overactive bladder (OAB) and urgency urinary incontinence (UUI). The study will involve a non-masked, non-inferiority randomized controlled trial design, where participants will be informed of their treatment assignment. Eligible women will have previously failed first- and second-line treatments and will undergo a thorough evaluation to confirm their diagnosis before enrollment. The study will assess the outcomes over a series of office visits to monitor the effectiveness of the interventions.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with overactive bladder or urgency urinary incontinence who have not responded to conservative or pharmacologic treatments.

Not a fit: Patients with urinary fistulas, male genital anatomy, or those under 18 years old will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-surgical treatment option that significantly improves the quality of life for women with overactive bladder.

How similar studies have performed: Other studies have shown promising results with similar electrical stimulation approaches for treating overactive bladder, indicating potential for success.
