Evaluation of Autonomic Nervous System Changes in Response to Stimulation by Sacral Neuromodulation
Overactive bladder syndrome (OAB) is defined by urgent and frequent urges to urinate associated with frequent night-time urination and sometimes urinary incontinence. Sacral neuromodulation (SNM) is now one of the second-line treatments for OAB. The mode of action of SNM is still poorly understood but a number of data from recent scientific literature suggest that SNM may act, among other things, by altering the balance of the autonomic nervous system (ANS) - located at the interface between the urinary tract and the brain structures regulating the functioning of the urinary tract. The aim of this study would therefore be to develop a predictive tool for the effectiveness of SNM.
