Using tibial nerve stimulation to treat neurogenic bladder dysfunction

Transcutaneous Tibial Nerve Stimulation (TTNS) for Treating Neurogenic Lower Urinary Tract Dysfunction: a Multicentre, Randomised, Sham-controlled, Double-blind Clinical Trial

NA · University of Zurich · NCT04315142

This study is testing if a new non-invasive treatment using tibial nerve stimulation can help people with neurogenic bladder problems that haven't improved with regular medications.

What this trial studies

This clinical trial investigates the effectiveness of transcutaneous tibial nerve stimulation (TTNS) as a non-invasive treatment for patients suffering from neurogenic lower urinary tract dysfunction (NLUTD). The study compares the effects of TTNS against a sham treatment in individuals with refractory neurogenic bladder issues, aiming to improve their quality of life. Participants must have experienced urinary dysfunction that has not responded to conventional medications. The trial seeks to provide insights into the potential benefits of neuromodulation therapies for this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with refractory neurogenic bladder dysfunction due to a neurological disorder.

Not a fit: Patients who have not undergone recent urodynamic investigations or those whose bladder dysfunction is not refractory to standard treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve urinary function and quality of life for patients with neurogenic bladder dysfunction.

How similar studies have performed: Previous studies have shown that tibial nerve stimulation is effective for idiopathic overactive bladder, but its application in neurological patients is still being explored.

Inclusion Criteria:

* Informed consent
* Age ≥18 years
* Last urethro-cystoscopy and bladder washing cytology within 1 year before inclusion

  3. Combination of neurogenic OAB and neurogenic voiding dysfunction (i.e. urgency frequency syndrome with or without urgency incontinence and incomplete / complete urinary retention) refractory to antimuscarinics (pharmacotherapy for at least 4 weeks with at least 2 antimuscarinics) and alpha-blocker (pharmacotherapy with an alpha- blocker for at least 4 weeks)
