Fecal incontinence (FI) is a disabling problem affecting women. Conservative treatment includes dietary modification, antimotility agents, and pelvic floor physical therapy. If conservative medical management is unsuccessful, surgical intervention may be required. Surgical options include rectal sphincteroplasty, bulking agent injection, radiofrequency anal sphincter remodeling procedure and sacral nerve stimulation (SNS) therapy. Recently, a new therapy for FI, the FENIX Continence Restoration System has become available...

REVIEW
Amanda S J Chung, Kurt A McCammon
Lower urinary tract symptoms (LUTS) after urethral stricture repair are not uncommon. Urgency has been reported in 40% of men and urge incontinence in 12% of men after anterior urethroplasty. De novo urgency and urge incontinence is seen in 9 and 5% of men, respectively, after urethroplasty. Once a complication of urethroplasty (such as recurrent urethral stricture or diverticulum) has been excluded as a cause, evaluation of LUTS in such patients should focus on differentiating bladder dysfunction (overactive bladder, underactive bladder), from other outlet obstruction (such as benign prostatic obstruction), dysfunctional voiding, or medical causes (such as nocturnal polyuria)...

Overactive bladder (OAB) affects millions of people around the world and decreases quality of life for those affected. Over the past two decades, significant advances in treatment have transformed the lives of those with OAB. Sacral neuromodulation (SNM), posterior tibial nerve stimulation (PTNS), and dorsal genital nerve stimulation are the most effective contemporary treatment modalities. New techniques and bio-sensing schemes offer promise to advance therapy beyond what is currently available. Current neuromodulation techniques do not use real-time data from the body or input from the patient...

Overactive bladder (OAB) syndrome is a highly prevalent condition that may lead to medical complications and decreased quality of life. Emerging therapies focusing on selective electrical stimulation of peripheral nerves associated with lower urinary tract (LUT) function may provide improved efficacy and reduced side effects compared to sacral neuromodulation for the treatment of OAB symptoms. Prior studies investigating the effects of pelvic nerve (PelN) stimulation on LUT function were focused on promoting bladder contractions, and it is unclear if selective stimulation of the PelN would be beneficial for the treatment of OAB...

PURPOSE: Sacral nerve and tibial nerve stimulation have been singly used to treat overactive bladder (OAB). This study evaluated the effects of both combined stimulation on treating bladder overactivity in pigs and explored a novel treatment modality for OAB. METHODS: An implant-driven stimulator of the S3 spinal nerve was implanted in 5 pigs. The contralateral tibial nerve was stimulated by an external stimulator. Multiple cystometrograms were performed to determine the effects of single nerve stimulation and combination sacral nerve stimulation (SNS) and tibial nerve stimulation (TNS) on the micturition reflex by infusing normal saline (NS) or acetic acid (AA)...
