Transcutaneous Tibial Nerve Stimulation for Treating Neurogenic Lower Urinary Tract Dysfunction
- Conditions
- Neurogenic Bladder Dysfunction
- Interventions
- Device: Transcutaneous Tibial Nerve Stimulation (TTNS)
- Registration Number
- NCT02859844
- Lead Sponsor
- University of Zurich
- Brief Summary
Many patients with neurological diseases suffer from neurogenic lower urinary tract dysfunction (NLUTD), which often severely impairs quality of life, due to urinary urgency with or without incontinence and voiding dysfunction. In addition, the upper urinary tract may be jeopardized because of high intravesical pressure caused by detrusor overactivity with concurrent detrusor-sphincter-dyssynergia and/or low bladder compliance. The treatment of NLUTD is a challenge since conventional conservative therapies often fail and more invasive treatments such as intradetrusor onabotulinumtoxinA injections, bladder augmentation and urinary diversion have to be considered. Neuromodulation therapies including tibial nerve stimulation (TNS) may be alternative non-invasive treatment options. Indeed, TNS is an effective and safe treatment for idiopathic overactive bladder proven in randomized controlled trials (RCTs), but its value in neurological patients is unclear. In a recent systematic review, the investigators found evidence that TNS might become a promising treatment option for NLUTD, however, more reliable data from well-designed RCTs are urgently needed to reach definitive conclusions. However, the investigators study will be the first adequately sampled and powered, randomized, placebo-controlled, double-blind trial assessing transcutaneous TNS (TTNS) for NLUTD. This trial will provide significant insights into the efficacy of TTNS in patients suffering from NLUTD and in the case that this treatment is really effective in the neurological population, the investigators findings would completely revolutionize the management of NLUTD in daily clinical practice. Moreover, this interdisciplinary trial will relevantly influence the neurological and urological approach in the management of NLUTD promoting future collaborative projects improving patients' medical care and underlying the pioneering role of Switzerland in the rapidly developing and ambitious research field of neuro-urology.
