Percutaneous electrical stimulation of the posterior tibial nerve for the treatment of fecal incontinence: manometric results after 6 months of treatment.

Background: Posterior tibial nerve stimulation (PTNS) is a minimally invasive approach with little adverse effects, but obtaining good results as shown in the different scales for the evaluation of the severity of incontinence. The aim of this study was to determine the effects of PTNS based on manometric determinations of the anal sphincter and severity during a period of treatment of 6 months (18 sessions).

Patients And Methods: A prospective interventional study of patients with fecal incontinence was performed.
