Brain Effects of Sacral Neuromodulation

This study is currently recruiting participants.
Verified by University Hospital Inselspital, Berne, July 2008

Sponsored by: University Hospital Inselspital, Berne
Information provided by: University Hospital Inselspital, Berne
ClinicalTrials.gov Identifier: NCT00610064
  Purpose

Sacral neuromodulation (SNM) has become an accepted treatment for patients with refractory lower urinary tract dysfunction such as urgency frequency syndrome, urgency incontinence, non-obstructive chronic urinary retention and chronic pelvic pain syndrome. Modulation of central afferent activity is considered critical to this therapeutic effect but the neural mechanisms are poorly understood.

We hypothesize that SNM has a significant effect on brain activity detectable by positron emission tomography (PET).


Condition Intervention
Urinary Tract Disease
