[Does urinary sacral neuromodulation improve bowel symptoms other than fecal incontinence: A systematic review]. / La neuromodulation sacrée urinaire a-t-elle un effet sur les troubles digestifs autre que l'incontinence fécale : revue de la littérature.

ABSTRACT

PURPOSE: To evaluate literature data about urinary sacral neuromodulation and its effects on bowel symptoms other than fecal incontinence. METHOD: A systematic review was conducted using PubMed/Medline with the following keywords sacral neuromodulation, urinary incontinence, voiding symptoms, intestinal bowel syndrome, constipation, epidemiology. RESULTS: Urinary SNS seems to improve intestinal bowel symptoms scores (level of evidence 4). However, for constipation, there are more contrasting results. If symptoms scores seem to improve, QOL scores are not significantly changed. Furthermore, some people reported an aggravation of their constipation symptoms (level of evidence 4). Those contrasted results could be explained by the various causes of constipation which implies various pathophysiological pathways. CONCLUSIONS: A better evaluation of digestive symptoms in patient candidate to urinary SNS could help identifying patients able to be improve by SNS. LEVEL OF EVIDENCE 4.
