This preliminary study demonstrates that percutaneous tibial nerve stimulation is an effective and very well tolerated treatment for patients with urge fecal incontinence with particular improvement in reducing fecal urgency.

PTNS is an effective treatment in female patients with FI. Improvements in clinical outcomes were independent of damage to the anal sphincter complex in patients with normal rectal sensation.

PTNS is a well-tolerated treatment with high acceptability in the majority of patients. It provides a sustained improvement in FI up to 42 months in a relatively noninvasive manner. The effect of PTNS diminishes with time and additional therapy sessions at 6 monthly intervals may result in greater improvements. PTNS ought to be considered as the first step in all patients with FI refractory to maximum conservative therapies.
