Combined magnetic stimulation and ultrasound for detrusor overactivity in spinal cord injury
Official title: A Randomized, Double-Blind, Sham-Controlled Trial of Sacral Nerve Root High-Frequency Magnetic Stimulation Combined With Ultrasound Therapy for Detrusor Overactivity in Patients With Spinal Cord Injury
Run by Shengjing Hospital · NCT07704268 · Data updated 2026-11-12
This study tests whether using high-frequency sacral nerve stimulation together with bladder-directed ultrasound can reduce involuntary bladder contractions and improve bladder function in people with spinal cord injury.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults 18-80 with SCI above the sacral level and documented detrusor overactivity who can comply with study visits and procedures.
✕Probably not a fit
Patients without detrusor overactivity or with unstable medical conditions or implants near the stimulation area may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The trial assesses whether combining two therapies—high-frequency sacral nerve root magnetic stimulation and bladder-directed ultrasound—provides added benefit over magnetic stimulation alone for detrusor overactivity in SCI. Participants are randomly assigned to receive magnetic stimulation, bladder ultrasound, or both, once daily for three weeks (seven sessions per week). Before and after treatment, urodynamic testing and bladder/urinary tract ultrasound assess safety and bladder health, along with voiding diaries and validated quality-of-life questionnaires. The study is conducted at the Rehabilitation Center of Shengjing Hospital in Shenyang, China, sponsored by Shengjing Hospital.
Why it matters
Potential benefit: If successful, the combined therapy could offer a more effective non-pharmacologic option to reduce detrusor overactivity and improve urinary function in SCI patients.
How similar studies have gone: Previous approaches using neuromodulation or ultrasound for bladder function have shown potential benefits, but the combined approach is exploratory.
