Sacral and tibial nerve stimulation to improve bladder function after recent suprasacral spinal cord injury

Effectiveness of Transcutaneous Tibial and Sacral Nerve Stimulation in Preventing the Development of Detrusor Overactivity in Patients With Subacute Suprasacral Spinal Cord Injury

Not applicable Interventional Ankara City Hospital Bilkent · NCT07343583

This trial will test whether noninvasive sacral or tibial nerve stimulation can prevent or reduce overactive bladder in adults within six months of a suprasacral spinal cord injury.

What this trial studies

Adults with traumatic or non‑traumatic suprasacral spinal cord injury (within six months of injury and above T11) are randomly assigned to transcutaneous tibial nerve stimulation (TTNS), transcutaneous sacral nerve stimulation (TSNS), or standard care without neuromodulation. Intervention groups receive 15 sessions of noninvasive neuromodulation, with urodynamic evaluations used to measure detrusor activity and bladder pressures before and after the intervention period. The protocol compares the two stimulation sites to determine which, if either, better prevents development or progression of neurogenic detrusor overactivity in the subacute phase. Outcomes focus on objective urodynamic measures and clinically relevant bladder symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18–65 with a suprasacral (above T11) spinal cord injury of less than six months' duration who do not have pacemakers, active urinary infection, other neurologic diseases affecting the bladder, prior pelvic radiation or bladder surgery, or medications that alter bladder function.

Not a fit: Patients with chronic (>6 months) or lower motor neuron spinal injuries, structural genitourinary abnormalities, active urinary tract infection, prior neuromodulation after injury, pacemakers, or other excluded conditions are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, these noninvasive approaches could reduce urinary incontinence and high bladder storage pressures, lowering the risk of kidney damage and the need for medications or invasive procedures.

How similar studies have performed: Transcutaneous tibial nerve stimulation has shown benefit in some neurogenic and non‑neurogenic bladder disorders, while transcutaneous sacral stimulation is less well studied and comparative data in subacute SCI are currently lacking.
