Neurourology and Urodynamics

BACKGROUND: Obesity is a modifiable risk factor for urinary incontinence, yet few studies have investigated how waist circumference as compared to body mass index (BMI) influences the risk of urinary incontinence. OBJECTIVE: To estimate how BMI and waist circumference associates with risk of urinary incontinence in midlife and determine which of the two is the strongest predictor of urinary incontinence. METHODS: Cohort study among mothers in the Danish National Birth Cohort...

AIMS: Sacral neuromodulation (SNM) is an advanced therapy option for the treatment of overactive bladder (OAB), nonobstructive urinary retention, and fecal incontinence. The aim of this ongoing prospective, multicenter, global, postmarket study is to confirm safety and clinical performance of the InterStimTM Micro system for SNM in all indications. Reported here are the results for the OAB cohort through 6-month follow-up. METHODS: Eligible OAB subjects that had a successful therapy evaluation were enrolled after implant of an InterStim Micro implantable pulse generator (IPG)...

INTRODUCTION: Few instruments measure knowledge, attitudes, and beliefs (KAB) related to bladder health. Existing questionnaires have predominantly focused on KAB related to specific conditions such as urinary incontinence, overactive bladder, and other pelvic floor disorders. To address this literature gap, the Prevention of Lower Urinary Tract Symptoms (PLUS) research consortium developed an instrument that is being administered in the baseline assessment of the PLUS RISE FOR HEALTH longitudinal study...

INTRODUCTION: The prevalence of healthy bladder storage and emptying function in community-dwelling women is not well established. 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. Overall healthy bladder function was defined as ≤8 waking/daytime voids and ≤1 void during sleeping/nighttime; along with the absence of leakage, urgency, emptying difficulties (initiation, flow, efficacy, relief of urge sensation) and pain...

INTRODUCTION: Sacral neuromodulation (SNM) is a treatment approved for use in several conditions including refractory overactive bladder (OAB) and voiding dysfunction. Chronic pelvic pain (CPP) is a debilitating condition for which treatment is often challenging. SNM shows promising effect in patients with refractory CPP. However, there is a lack of clear evidence, especially in long-term outcomes. This systematic review will assess outcomes of SNM for treating CPP. METHODS: A systematic search of MEDLINE, Embase, Cochrane Central and clinical trial databases was completed from database inception until January 14, 2022...

INTRODUCTION: Radiofrequency (RF) energy application stimulates collagen and elastin remodeling to restore the elasticity, and moisture of the superficial vaginal mucosa. This is the first study to report on the use of microneedling to deliver RF energy to the vaginal canal. Microneedling increases the response of the collagen contraction and neocollagenesis in deeper layers of tissue, thus increasing the support to the surface. The novel intravaginal microneedling device used in this study allows penetration of the needles to 1, 2, or 3 mm...

BACKGROUND: We aimed to study the test-retest reliability of the Multiple Array Probe Leiden (MAPLe), a multiple electrode probe designed to acquire and discriminate electromyography signals in the pelvic floor muscles, in men with lower urinary tract symptoms (LUTS). METHODS: Adult male patients with LUTS with sufficient knowledge of Dutch language, but without complications (e.g., urinary tract infection), or previous urologic cancer and/or urologic surgery were enrolled...

OBJECTIVE: To quantitate the changes in stress urinary incontinence (SUI) outcome measures after 12 weeks of vaginal estriol cream in women with stress incontinence. METHODS: A prospective multicentre observational study conducted in tertiary urogynaecology centers. Postmenopausal women with pure SUI or stress predominant mixed urinary incontinence (MUI), not receiving any other treatment for their incontinence were given written instructions regarding digital application of a standard dose of vaginal estriol cream...

PURPOSE: Chronic pelvic pain syndromes (CPPS) are commonly encountered by urologists and urogynecologists and pose diagnostic and therapeutic challenges. Body maps have been helpful adjuncts to verbal descriptions of pain and may serve a role in phenotyping what is known to be a heterogeneous patient population. The aim of this study was to assess whether patterns of pain as marked on a body map of the pelvis exist among common CPPS diagnoses. The secondary aim was to investigate the association between the total number of pain locations marked on the map and clinical indices in patients with 1 to 3 CPPS diagnoses...

INTRODUCTION/BACKGROUND: The pulse width (PW) parameter in sacral neuromodulation (SNM) is understudied, with no evidence-based guidance available on optimal PW for urinary indications. The aim of this prospective, randomized, single-blinded, 3 × 3 cross over design study was to estimate the effect of two PW settings (60 µs, 420 µs) compared to the industry standard (210 µs) on SNM efficacy, quality of life, and device parameters in patients who were stable and satisfied with their SNM treatment...

PURPOSE: Sparse published reports exist nowadays on vibegron and pediatric overactive bladder, so its usefulness of this agent remains unclear. The purpose of this study was to clarify the effectiveness of vibegron for pediatric cases of daytime urinary incontinence (DUI), including refractory cases. METHODS: Participants comprised 57 patients treated with vibegron for DUI from March 2019 to April 2022. To investigate treatment outcomes and risk factors for pediatric patients with refractory DUI, the following factors were evaluated: age at initiatial administration; frequency of DUI; duration of vibegron treatment; presence of neurodevelopmental disorders (NDDs); presence of constipation; and anticholinergic medications before and after initiation of treatment...

OBJECTIVE: To develop a novel predictive model for identifying patients who will and will not respond to the medical management of benign prostatic hyperplasia (BPH). METHODS: Using data from the Medical Therapy of Prostatic Symptoms (MTOPS) study, several models were constructed using an initial data set of 2172 patients with BPH who were treated with doxazosin (Group 1), finasteride (Group 2), and combination therapy (Group 3). K-fold stratified cross-validation was performed on each group, Within each group, feature selection and dimensionality reduction using nonnegative matrix factorization (NMF) were performed based on the training data, before several machine learning algorithms were tested; the most accurate models, boosted support vector machines (SVMs), being selected for further refinement...

AIMS: The aim of this study was to compare the clinical characteristics of men with lower urinary tract symptoms (LUTS) grouped by 24-h urine output determined from a bladder voiding diary. METHODS: An online database was queried to identify men who completed a 24-hour bladder diary (24HBD), and the Lower Urinary Tract Symptom Score (LUTSS) questionnaire from 2015 to 2019 using a mobile app. Data from the bladder diary and questionnaire were contemporaneously matched within a 2-week period...

INTRODUCTION: Midurethral tapes (MUTs) were the most common surgical treatment for stress urinary incontinence (SUI) between 2008 and 2017. Transobturator tapes were introduced as a novel way to insert MUTs. Some women have experienced life-changing complications, and opt to undergo a total excision of transobturator tape (TETOT). There is a paucity in evidence about the outcomes of TETOT, which is a complex operation. This study aims to report clinical outcomes of all women who underwent TETOT in a specialist mesh center...

AIMS: Pelvic floor symptoms (PFS), including lower urinary tract symptoms, defecation problems, sexual dysfunction, and pelvic pain, are common in males and females. Comparing pelvic floor musculature (PFM) function between sexes may reveal important differences relevant to clinical care. This study aimed to compare male and female PFM function and to assess the function of both sexes with the number and type of PFS. METHODS: We purposively enrolled males and females aged ≥ 21 years with 0-4 PFS based on questionnaire responses in an observational cohort study...
