Purpose: Sacral nerve stimulation is an effective treatment for patients suffering from fecal incontinence. However, less is known about predictors of success before stimulation. The purpose of this study was to identify predictors of successful sacral nerve stimulation in patients with idiopathic fecal incontinence.
Methods: Consecutive female patients, receiving peripheral nerve evaluation and sacral nerve stimulation between September 2008 and October 2014, suffering from idiopathic fecal incontinence were included in this study. Preoperative patient's characteristics, anal manometry, and defecography results were collected prospectively and investigated by retrospective analysis. Main outcome measures were independent predictors of treatment success after sacral nerve stimulation.
Results: From, all in all, 54 patients suffering from idiopathic fecal incontinence receiving peripheral nerve evaluation, favorable outcome was achieved in 23 of 30 patients after sacral nerve stimulation (per protocol 76.7%; intention to treat 42.6%). From all analyzed characteristics, wide anorectal angle at rest in preoperative defecography was the only independent predictor of favorable outcome in multivariate analysis (favorable 134.1 ± 13.9° versus unfavorable 118.6 ± 17.1°).
Conclusions: Anorectal angle at rest in preoperative defecography might present a predictor of outcome after sacral nerve stimulation in patients with idiopathic fecal incontinence.

Importance: Patients deciding between advanced therapies for overactive bladder syndrome may be interested to know the likelihood of treatment crossover after sacral neuromodulation, intradetrusor OnabotulinumtoxinA, or percutaneous tibial nerve stimulation. Treatment crossover was defined as a switch from one advanced therapy to another.
Objectives: The aim of this study was to estimate the rate of treatment crossover after each advanced therapy for nonneurogenic overactive bladder syndrome.

Fecal incontinence is a common condition that can significantly impact patients' quality of life. Obstetric anal sphincter injury and anorectal surgeries are common etiologies. Endoanal ultrasound and anorectal manometry are important diagnostic tools for evaluating patients.

Bladder dysfunction is a common clinical problem in stroke patients and a strong prognostic factor of disability and exerts an enormous impact on health and economy. The aim of this narrative review was tο examine the pathophysiological mechanisms of lower urinary tract symptoms after stroke, as well as the relevant clinical anatomy. Normal micturition is achieved through complex coordination between brain regions, spinal cord, and peripheral nerves, and anatomic brain connectivity is crucial to lower urinary tract physiology.

Objective: To identify the sonomorphological appearance and to measure the thickness of the piriformis muscle (PM) and the proximal portion of the sacral nerve roots S1-S3 in healthy premenopausal women.
Materials And Methods: This prospective multicentric observational study included a consecutive series of women undergoing transvaginal sonography (TVS) at two tertiary gynecological referral centers. Standardized assessment of the pelvic organs was performed followed by an attempt to visualize the right and left PM and sacral nerve roots S1-S3 at their origin in proximity to the sacral neuroforamen.
