Objective: The objective of this study is to characterize an acceptable health state, using the patient acceptable symptom state (PASS) question, in adult women with urinary incontinence.

Methods: This is a prospective multicenter cohort study determining PASS thresholds from condition-specific measures using an electronic research platform in English-speaking women seeking nonsurgical treatment of urinary incontinence between March 2019 and May 2020. Exclusions included pregnancy, isolated overactive bladder, and pelvic organ prolapse greater than stage II.

Objectives: To evaluate if age and medical comorbidities are associated with progression to implantation of sacral neuromodulation devices in women with symptomatic chronic urinary retention.

Methods: This multisite retrospective cohort included women with symptomatic chronic urinary retention who had a trial phase of sacral neuromodulation. The primary outcome was progression to implantation.

Objective: To evaluate changes in self-reported depression after treatment of fecal incontinence (FI) with sacral neuromodulation.

Materials And Methods: This is a subanalysis of data collected from March 2016 to October 2017 for an Institutional Review Board-approved retrospective cohort study. Demographic information, medical history, psychiatric comorbidities, and the Patient-Reported Outcomes Measurement Information System item bank t-scores were extracted from the electronic medical record.

Objective: To evaluate if age and comorbidities are associated with progression from trial phase to implantation of an implantable pulse generator in women with overactive bladder.

Methods: This multisite retrospective cohort included women with overactive bladder with or without urinary incontinence who had a trial phase for sacral neuromodulation. The primary outcome was progression to implantation.

Objective: To identify risk factors associated with surgical revision of midurethral sling (MUS) due to mesh extrusion.

Materiald And Methods: This is a case-control study identifying women who underwent primary surgical revision of polypropylene MUS for vaginal mesh extrusion from 2001 to 2016. Cases of surgical revision were compared to a randomly selected control group in a 1:5 ratio.

Purpose: The aim of this study is to evaluate changes in sleep disturbance following treatment of overactive bladder with sacral neuromodulation.

Materials And Methods: This is a sub-analysis of data collected from an institutional review board approved retrospective cohort study evaluating women with Patient-Reported Outcomes Measurement Information System-Sleep Disturbance (PROMIS-SD) before and after sacral neuromodulation for overactive bladder between March 2016 and October 2017. Data collected included demographics, clinical characteristics, and additional PROMIS item banks.

Purpose: To examine associations if any between changes in voiding function, hematuria, and bladder ultrasonography metrics in murine cyclophosphamide-induced chemical cystitis.

Materials And Methods: Cystitis was induced in 6 female mice by an intraperitoneal injection of cyclophosphamide (300 mg/kg). Voiding frequency, void volume, hematuria assessment, and ultrasonographic measurements of the bladder were obtained at baseline, days 1 to 5, and days 9, 11, and 13.

Objective: This study aimed to determine the incidence and risk factors associated with revision or removal of a sacral nerve stimulation device for treatment of lower urinary tract dysfunction or fecal incontinence.

Materials And Methods: This is a single-center multidisciplinary retrospective cohort study conducted at a university hospital from January 2013 through October 2017. Subjects who underwent successful sacral neuromodulation were identified via procedural codes.

Introduction And Hypothesis: In the United States, vesicovaginal fistula (VVF) most often results from gynecologic surgery causing significant morbidity and distress to both the patient and surgeon. The use of tissue interposition at time of primary repair has been advocated to decrease the risk of recurrence. The aim of this study is to describe our experience with interposition of sigmoid epiploica during robotic extravesical repair of supratrigonal VVF.

Background: Rates of administration of intravenous sodium fluorescein during cystoscopy have increased since indigotindisulfonate sodium was removed from the market in 2014. Although sodium fluorescein has been extensively evaluated and found to be safe, side effects including anaphylaxis have been observed, with an incidence between 0.05% and 1.

Transobturator tape procedure is a popular and effective minimally invasive technique to treat stress urinary incontinence. We report a case of transient obturator neuropathy caused by transobturator tape placement for stress urinary incontinence. Findings on physical examination were significant for bilateral obturator neuropathy resulting in significant motor deficit, prompting removal of the sling to avoid the potential of prolonged or permanent morbidity.
