BACKGROUND: Low anterior resection for rectal cancer often results in severe bowel dysfunction, specifically low anterior resection syndrome (LARS), with symptoms such as incontinence, urgency, and frequent bowel movements. Percutaneous tibial nerve stimulation (PTNS) resulted in a high rate of success in patients with fecal incontinence. The aim of this study was to evaluate the effectiveness of treatment with PTNS in LARS and to identify predictors of the outcome of the technique. METHODS: The study was conducted from May 2012 to April 2015 at the Alvaro Cunqueiro Hospital, University Hospital Complex of Vigo, Spain...

PURPOSE: Percutaneous tibial nerve stimulation (pTNS) was originally developed to treat urinary incontinence. Recently, some case series have also documented its success in the treatment of fecal incontinence. Nevertheless, the mechanism underlying this effect remains unknown but may be related to changes in rectal capacity. The aim of this study was to investigate the success of pTNS for the treatment of fecal urge incontinence and assess the influence of rectal capacity on treatment efficacy...

AIM: Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive procedure, which has been demonstrated to be effective in faecal/urinary incontinence, but has never been tested in Low Anterior Resection Syndrome (LARS). The severity of LARS may be evaluated by the LARS-score, but rectal cancer treatments may also affect urinary and sexual function, which are not explored by the LARS-score. The TAPE-score is a new validated index addressing the overall pelvic-floor functions...

Posterior Tibial Nerve Stimulation (PTNS) is an effective overactive bladder (OAB) therapy where electrical pulses are typically delivered once per week in a 12-week stimulation regime. While the mechanism of action remains unknown, effective long-term delivery of PTNS has recently become a subject of concern. To this end, a multi-contact electrode was surgically placed in the hind limb region of anesthetized cats to (1) investigate the feasibility of using a wirelessly powered system to stimulate PTN afferents and (2) characterize implant-driven effects of stimulation frequency on modulating bladder activity...

Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive and effective treatment for overactive bladder (OAB). However, clinical trials show that positive therapeutic outcomes among patients are difficult to predict (failure rate = 35% to 50%). Inconsistencies in the stimulation amplitudes used clinically and those used in preclinical animal studies led us to hypothesize that OAB therapy involves a secondary bladder-inhibitory pathway. In this paper, we implemented and tested a computer model of the human lower leg that investigated the differential activation of the saphenous nerve (SAFN) and tibial nerve (TN) during percutaneous electrical stimulation...

Posterior Tibial Nerve Stimulation (PTNS) is a minimally invasive yet effective therapy for treating overactive bladder (OAB) symptoms with electrical stimulations applied at 20 Hz coupled with amplitudes approximating the foot-twitch threshold (T). However, pre-clinical studies indicate that PTNS-evoked bladder reflexes require stimulation amplitudes exceeding 2T. The objective of this work was to evaluate the presence of secondary low-threshold sensory pathways in the hind-limb region that can be a potential target of activation during clinical PTNS set-up...

AIM: Chronic constipation can be aetiopathogenically classified into slow transit constipation (STC), rectal evacuation difficulty (RED) or a combination (BOTH). Although the efficacy of percutaneous tibial nerve stimulation (PTNS) in faecal incontinence has been well proved, a current literature search identifies only one study which assessed its effect on constipation. We aimed to evaluate the effectiveness of PTNS in patients with different causes of constipation. METHOD: Thirty-four patients [30 women, median age 50 (20-79) years] with constipation who had previously failed maximal laxative and biofeedback therapy participated in the study...

REVIEW
Melissa T Sanford, Anne M Suskind
While neuromodulation is a well-established treatment option for patients with non-neurogenic overactive bladder and urinary retention, its applicability to the neurogenic bladder population has only recently been examined more in depth. In this article we will discuss the outcomes, contraindications, and special considerations of sacral and percutaneous tibial nerve stimulation (PTNS) in patients with neurogenic lower urinary tract dysfunction.
