Transcutaneous sacral magnetic versus electrical stimulation for overactive bladder after spinal cord injury

Official title: The Effectiveness of Transcutaneous Sacral Neuromodulation Techniques-Magnetic Stimulation and Electrical Stimulation-on Detrusor Overactivity in Patients With Spinal Cord Injury

Run by Ankara City Hospital Bilkent · NCT07578532 · Data updated 2026-11-12

This trial will try two noninvasive sacral stimulation methods—magnetic and electrical—to see which better reduces bladder overactivity in adults (18–65) with suprasacral spinal cord injury who still have symptoms despite anticholinergic drugs.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with traumatic or nontraumatic suprasacral spinal cord injury, urodynamically confirmed detrusor overactivity, and stable anticholinergic/sympathomimetic treatment for at least 3 months are ideal candidates.

Probably not a fit

Patients with cardiac pacemakers, epilepsy, metal implants near the treatment site, recent bladder botulinum toxin or neuromodulation within 6 months, prior neurogenic bladder surgery, or other neurological diseases affecting bladder function are excluded and unlikely to benefit from these interventions in this trial.

What this trial studies

This is a prospective, randomized trial enrolling 40 adults with suprasacral spinal cord injury and urodynamically confirmed detrusor overactivity that is refractory to stable anticholinergic treatment. Participants are randomly assigned to receive either transcutaneous sacral magnetic stimulation (SMS) or transcutaneous sacral electrical stimulation (SES). Investigators will compare objective urodynamic measures (including maximum detrusor pressure during filling and bladder compliance), frequency of incontinence episodes, Neurogenic Bladder Dysfunction Score, and patient-reported discomfort/satisfaction. Safety and tolerability of both noninvasive stimulation approaches will also be recorded.

Why it matters

Potential benefit: If successful, one of these noninvasive stimulation methods could lower bladder pressures, reduce incontinence, and improve quality of life while avoiding or reducing reliance on medications or invasive procedures.

How similar studies have gone: Previous small studies and clinical experience with sacral electrical and magnetic stimulation show potential benefit for neurogenic detrusor overactivity, but direct randomized head-to-head comparisons are limited.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* 18-65 years old Traumatic and non-traumatic suprasacral SCI; Detrusor overactivity confirmed by urodynamics (spontaneous and/or provocative detrusor contraction during the filling phase will be accepted as detrusor overactivity) Patients who have been receiving anticholinergic and/or sympathomimetic treatment for the last 3 months and whose pharmacological medical treatment dose has not been changed since the last urodynamic examination will be included in the study.

Exclusion Criteria:

* Patients with a cardiac pacemaker,
* Patients diagnosed with epilepsy,
* Patients with a metal implant within a 10 cm radius of the area where the treatment will be applied,
* Patients who have received botox injection to the bladder in the last 6 months,
* Patients who have received any neuromodulation technique in the last 6 months,
* Patients who have undergone surgical procedure for neurogenic bladder,
* Patients with another neurological disease that may affect neurogenic bladder (Parkinson's, polyneuropathy, neurodegenerative disease, cerebrovascular disease, etc.)
* Patients with acute urinary tract infection,
* Patients diagnosed with bladder outlet obstruction (urethral stricture, benign prostatic hyperplasia, etc.) will not be included in the study.
