Sacral Neuromodulation for Neurogenic Lower Urinary Tract, Bowel and Sexual Dysfunction

Multiple Sclerosis Clinical Trial

Official title: Sacral Neuromodulation for Patients With Multiple Sclerosis With Neurogenic Lower Urinary Tract, Bowel and Sexual Dysfunction. A Multicenter Double-blind, Placebo-controlled Randomized Clinical Trial.

Status Recruiting

Clinical Trial Summary

A multi-center double-blinded placebo-controlled randomized clinical trial.

The patients will be randomized into two groups.

To investigate the efficacy of SNM to improve the key bladder diary variables compared to placebo (i.e. sham) for patients with MS having refractory neurogenic lower urinary tract dysfunction (NLUTD).

After first step SNM-procedure and a 3-4 weeks test period patients with more than 50% improvement in the key bladder diary variables will have the IPG implanted. After a month of optimization patients will into two groups: IPG ON or IPG OFF.

Period of randomization: four months. Number anticipated to be included: 60 patients

Clinical Trial Description

Patients with MS often suffer from pelvic-organ dysfunctions, i.e. lower urinary tract (LUT), bowel and sexual dysfunction, aside their cerebral affection. Sacral neuromodulation (SNM) is a reversible minimal invasive procedure affecting the function of the aforementioned pelvic organs. Changes in bladder, bowel and sexual function will be monitored.

Primary outcome:

Success of SNM for lower urinary tract dysfunction as improvement of at least 50% in the key bladder diary variables (i.e. number of voids and/or number of leakages, post void residual) compared to the baseline values.

Secondary outcome:

To assess the changes in bladder, bowel and sexual function due to SNM by using subjective patient reported outcome measures, quality of life and global assessment score,

• To assess the changes in urodynamic variables,

• To assess the safety of SNM for NLUTD and

• To register the implantation characteristics and the need for reprogramming

Data will be collected at Baseline 1: At inclusion Baseline 2: At evaluation after a three weeks test period Baseline 3: At randomization Baseline 4: At the end of study

The time frame of the RCT is six months

Patients with improvements of bowel symptoms only will be excluded from the trial but followed with the same questionnaires for the same time.

The patients will be followed-up every 6 months for a total of 5 years. ;
