Transcutaneous Tibial Nerve Stimulation for Treating Neurogenic Lower Urinary Tract Dysfunction

August 31, 2020 updated by: University of Zurich
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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
