Background: Prior studies have failed to demonstrate clinical or statistical difference in fecal incontinence (FI) symptom improvement with neuromodulation by percutaneous tibial nerve stimulation (PTNS) vs sham. The results of these studies may be indicative of a placebo or sham effect and led us to investigate possible genetic biomarkers of placebo response among women with FI.
Objective: To evaluate the relationship between response to PTNS or sham and genetic polymorphisms associated with placebo response in women with FI.
Importance: Overactive bladder is a distressing syndrome that significantly affects quality of life. Transcutaneous tibial nerve stimulation (TTNS) has been proposed as a home-based, patient-centered therapy that could improve access to treatment for this condition.
Objective: We aimed to determine the efficacy of 12 weeks of TTNS versus sham therapy in reducing symptomatic bother in ambulatory women with urgency urinary incontinence.
Background: Bladder health encompasses total bladder well-being and not merely the absence of urinary symptoms. While much is known about the prevalence of urinary symptoms in women, little is known about the distribution of bladder health (eg, optimal to poor).
Objective: We report the distributions of multiple dimensions of bladder health and function in a population-based sample of community-dwelling women, overall and separately in women without urinary symptoms to begin to explore bladder health dimensions that may precede the onset of symptoms.
Introduction: Uroflowmetry is often used to assess lower urinary tract symptoms (LUTS). Criteria for characterization of flow patterns are not well established, and subjective interpretation is the most common approach for flow curve classification. We assessed the reliability of uroflowmetry curve interpretation in adult women.

Importance: Feasibility of home urogenital microbiome specimen collection is unknown.
Objectives: This study aimed to evaluate successful sample collection rates from home and clinical research centers.
Study Design: Adult women participants enrolled in a multicentered cohort study were recruited to an in-person research center evaluation, including self-collected urogenital samples.
Purpose: We aimed to estimate the prevalence of a wide range of lower urinary tract symptoms (LUTS) in US women, and explore associations with bother and discussion with health care providers, friends, and family.
Materials And Methods: We analyzed baseline data collected from May 2022 to December 2023 in the RISE FOR HEALTH study-a large, regionally representative cohort study of adult female community members. LUTS and related bother were measured by the 10-item Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index, and discussion was assessed by a study-specific item.
The composition of the human vaginal microbiome has been linked to a variety of medical conditions including yeast infection, bacterial vaginosis, and sexually transmitted infection. The vaginal microbiome is becoming increasingly acknowledged as a key factor in personal health, and it is essential to establish methods to collect and process accurate samples with self-collection techniques to allow large, population-based studies. In this study, we investigate if using AssayAssure Genelock, a nucleic acid preservative, introduces microbial biases in self-collected vaginal samples.

Methods: A planned secondary analysis of a US cross-sectional study designed to validate a bladder health instrument was conducted in women aged ≥18 years. A subset was invited to complete the novel 2-day bladder health diary capturing bladder storage and emptying experiences.
Introduction And Hypothesis: In randomized trials both percutaneous tibial nerve stimulation (PTNS) and sham result in clinically significant improvements in accidental bowel leakage (ABL). We aimed to identify subgroups who may preferentially benefit from PTNS in women enrolled in a multicenter randomized trial.
Methods: This planned secondary analysis explored factors associated with success for PTNS vs sham using various definitions: treatment responder using three cutoff points for St.
Objective: The Prevention of Lower Urinary Tract Symptoms (PLUS) research consortium launched the RISE FOR HEALTH (RISE) national study of women's bladder health which includes annual surveys and an in-person visit. For the in-person exam, a standardized, replicable approach to conducting a pelvic muscle (PM) assessment was necessary. The process used to develop the training, the products, and group testing results from the education and training are described.

Objective: This study aimed to report evidence of validity of the self-administered, multidimensional bladder health scales and function indices for research in adult women.
Study Design: A cross-sectional population-based validation study with random assignment to paper or electronic administration was conducted using national address-based probability sampling supplemented by purposive sampling of women with lower urinary tract symptoms in 7 clinical research centers.
Objectives: To describe the methods for the in-person assessment of the RISE FOR HEALTH (RISE) study, a population-based multicenter prospective cohort study designed to identify factors that promote bladder health and/or prevent lower urinary tract symptoms in adult women, conducted by the Prevention of Lower Urinary Tract Symptoms Research Consortium (PLUS).
Methods And Results: A subset of RISE participants who express interest in the in-person assessment will be screened to ensure eligibility (planned n = 525). Eligible consenting participants are asked to complete 15 physical assessments in addition to height and weight, to assess pelvic floor muscle function, musculoskeletal (MSK) status, and pain, and to provide urogenital microbiome samples.
Replicability is a well-established challenge in microbiome research with a variety of contributing factors at all stages, from sample collection to code execution. Here, we focus on voided urine sample storage conditions for urogenital microbiome analysis. Using urine samples collected from 10 adult females, we investigated the microbiome preservation efficacy of AssayAssure Genelock (Genelock), compared with no preservative, under different temperature conditions.

Methods: Women aged 18 years or older with ≥3 months of moderate-to-severe FI that persisted after a 4-week run-in phase were randomized 2:1 (PTNS:sham stimulation) to 12 weekly 30-minute sessions in this multicenter, single-masked, controlled superiority trial. The primary outcome was change from baseline FI severity measured by St.
Urobiome research has the potential to advance the understanding of a wide range of diseases, including lower urinary tract symptoms and kidney disease. Many scientific areas have benefited from early research method consensus to facilitate the greater, common good. This consensus document, developed by a group of expert investigators currently engaged in urobiome research (UROBIOME 2020 conference participants), aims to promote standardization and advances in this field by the adoption of common core research practices.

However, clinical experience suggests that some women with outcome "failures" are asymptomatic and perceive their surgery to be successful and that other women have anatomic resolution but continue to report symptoms. Characterizing failure types could be a useful step to clarify definitions of success, understand mechanisms of failure, and identify individuals who may benefit from specific therapies.

Objective: The aim of this study was to describe effects of vaginal estrogen (VE) on the urogenital microbiome in postmenopausal women with recurrent urinary tract infections (rUTIs).
Methods: This is a secondary analysis of 17 participants enrolled in a randomized controlled trial of VE versus placebo on urinary tract infection recurrence in postmenopausal women with rUTIs. Paired clean-catch urine samples were collected at baseline and after 6 months of VE and sequenced using 16S rRNA gene sequencing.
Objectives: High-level evidence for second-line noninvasive treatments for fecal incontinence in women is limited. We present the rationale for and design of the NeuromOdulaTion for Accidental Bowel Leakage trial, a randomized controlled trial of percutaneous tibial nerve stimulation (PTNS) and validated sham stimulation in women with refractory accidental bowel leakage.
Methods: The rationale and goals for a 2-part study with a run-in phase, use of a generic pulse generator for PTNS and sham stimulation, masking, participant inclusion, primary and secondary outcome measures, and adverse event collection are described.
Objectives: The objective of this study was to compare efficacy and adverse events between 100 U and 200 U of onabotulinumtoxinA for 6 months in women with nonneurogenic urgency incontinence.
Methods: This is a secondary analysis of 2 multicenter randomized controlled trials assessing efficacy of onabotulinumtoxinA in women with nonneurogenic urgency incontinence; one compared 100 U to anticholinergics and the other 200 U to sacral neuromodulation. Of 307 women who received onabotulinumtoxinA injections, 118 received 100 U, and 189 received 200 U.
Background: Bladder health is an understudied state and difficult to measure due to lack of valid and reliable instruments. While condition specific questionnaires assess presence, severity and degree of bother from lower urinary tract symptoms, the absence of symptoms is insufficient to assume bladder health. This study describes the methodology used to validate a novel bladder health instrument to measure the spectrum of bladder health from very healthy to very unhealthy in population based and clinical research.
