Prospective clinical audit of two neuromodulatory treatments for fecal incontinence: sacral nerve stimulation (SNS) and percutaneous tibial nerve stimulation (PTNS).

Background And Purpose: Two types of neuromodulation are currently practised for the treatment of fecal incontinence (FI): sacral nerve stimulation (SNS) and percutaneous tibial nerve stimulation (PTNS). This study compares these therapies, as no data exist to prospectively assess their relative efficacy and costs.

Methods: The subjects of this study were two distinct cohorts undergoing SNS (between 2003 and 2008) or PTNS (2008-onwards) for FI.
