Overactive bladder

INTRODUCTION: Opinions differ on what drugs have both a rationale and a development potential for the treatment of bladder storage dysfunction. AREAS COVERED: In the present review, the focus is given to small molecule blockers of TRP channels (TRPV1, TRPV4, TRPA1, and TRPM8), P2×3receptor antagonists, drugs against oxidative stress, antifibrosis agents, cyclic nucleotide - dependent pathways, and MaxiK±channel - gene therapy. EXPERT OPINION: TRPV1 channel blockers produce hypothermia which seems to be a problem even with the most efficacious second-generation TRPV1 antagonists...

AIMS: There is limited evidence to support the efficacy of sacral neuromodulation (SNM) for older adults with overactive bladder (OAB). This study aims to report outcomes following SNM among nursing home (NH) residents, a vulnerable population with high rates of frailty and comorbidity. METHODS: This is a retrospective cohort study of long-stay NH residents who underwent a trial of percutaneous nerve evaluation (PNE) or Stage 1 permanent lead placement (Stage 1) between 2014 and 2016...

PURPOSE: This study aimed to investigate the effectiveness of the simplified intervention, consisting of fluid and caffeine management alone in older women with overactive bladder symptoms. PATIENTS AND METHODS: A quasi-experimental pretest-posttest design was used. Rural, community-dwelling older women were recruited at four senior centers in South Korea. Of the 63 participants initially enrolled, 34 met the inclusion criteria. One group (n = 15) used fluid and caffeine management alone (FM), and the other group (n = 12) used a combination of fluid and caffeine management and pelvic floor muscle training (FM+PFMT)...

PURPOSE: The suburethral sling procedure has been widely used as the first-line treatment for female stress urinary incontinence (SUI). This study retrospectively compared the long-term surgical outcomes and complications between retropubic and transobturator suburethral sling procedures. METHODS: From 2010 to 2022, a total of 533 women with SUI underwent retropubic pubovaginal sling (PVS) or transobturator tape (TOT) procedures using a synthetic polypropylene mesh with or without concomitant anterior colporrhaphy...

Patients with Parkinson's disease (PD) have disturbances in their bladder and sleep physiology that lead to nocturia and overactive bladder (OAB). These symptoms can be extremely bothersome and impact not only their quality of life (QoL) but also the QoL of their caretakers. We aim to highlight the changes in bladder and sleep physiology in PD and explore OAB/nocturia treatment strategies in this population.

An increasing number of young patients with severe bladder overactivity syndrome potentially caused by recreational ketamine use has been treated in our department. Ketamine has become a popular and increasingly used recreational drug in New Zealand. Ketamine bladder syndrome has been reported internationally; however, local New Zealand data do not exist. It can lead to irreversible damage to the bladder, and internationally, surgical procedures like cystectomy and urinary diversion or augmentation cystoplasty have been reported as necessary treatments...

Stretch-activated two-pore-domain potassium (K2 P) channels play important roles in many visceral organs, including the urinary bladder. The TWIK-related potassium channel, TREK-1, is the predominantly expressed K2 P channel in the urinary bladder of humans and rodents. Downregulation of TREK-1 channels was observed in the urinary bladder of patients with detrusor overactivity, suggesting their involvement in the pathogenesis of voiding dysfunction. This study aimed to characterize the long-term effects of TREK-1 on bladder function by using global and smooth muscle specific TREK-1 knock out (KO) mice...

This narrative review explores the use of external urinary catheters. These devices are available in various types and materials for male and female patients. The indications for the use of external urinary catheters include managing incontinence linked to overactive bladder and neurogenic lower urinary tract dysfunction. Contraindications to the use of external urinary catheters include urinary obstruction. Proper skin care and proactive infection control measures are necessary to prevent complications. The collection of a urine specimen for culture requires a standardized technique to prevent contamination...

BACKGROUND: Socioeconomic status inequality is an important variable in the emergence of urological diseases in humans. This study set out to investigate the association between the prevalence of overactive bladder (OAB) and the poverty income ratio (PIR) that served as a more influential indicator of socioeconomic status compared to education and occupation. METHOD: Data from the National Health and Nutrition Examination Survey (NHANES) conducted from 2007 to 2020 were used in this cross-sectional study...

PURPOSE: Overactive bladder (OAB) syndrome significantly impairs quality of life, often necessitating pharmacological interventions with associated risks. The fragility of OAB trial outcomes, as measured by the fragility index (FI: smallest number of event changes to reverse statistical significance) and quotient (FQ: FI divided by total sample size expressed as a percentage), is critical yet unstudied. MATERIALS AND METHODS: We conducted a systematic search for randomized controlled trials on OAB medications published between January 2000 and August 2023...

OBJECTIVE: Aim: The objective of this review paper is to comprehensively analyze and summarize the current understanding and clinical applications of Botulinum toxin in the field of urology. PATIENTS AND METHODS: Materials and Methods: The materials and methods for this review paper involved an extensive literature search on the use of Botulinum toxin in urology. Multiple online databases such as PubMed, Web of Science, and Google Scholar were utilized to gather peer-reviewed articles, clinical trials, and relevant books published within the last decades...

PURPOSE: Percutaneous Tibial Neuromodulation (PTNM) is used to treat Overactive Bladder (OAB). This analysis summarizes patient adherence to PTNM treatment and examines trends of other third-line therapy use during and after PTNM. METHODS: Optum's deidentified Clinformatics® Data Mart Database (CDM) and CMS Research Identifiable Files were queried for adults with OAB symptoms and who underwent PTNM treatment (2019-2020). We evaluated the proportion of patients who completed 12 visits within 1 year, and defined patients as treatment compliant if 12 PTNM visits were completed within 12 weeks...

To assess the pharmacologically relevant and selective muscarinic receptor occupancy in the bladder mucosa, we considered not only plasma drug concentrations but also urinary drug concentrations. The purpose of this study was to predict muscarinic receptor occupancy in the human bladder mucosa based on urinary concentrations in response to clinical dosages of antimuscarinic agents used to treat overactive bladder. The calculated mean plasma or serum unbound steady state concentrations were 0.06-11 nM in clinical dosages of five antimuscarinic agents...

OBJECTIVE: To determine whether duration of detrusor overactivity (DO) during a cystometric study is an independent predictive factor of upper urinary tract deterioration (UUTD) in patients with traumatic spinal cord injury (TSCI). STUDY DESIGN: Retrospective cohort study. SETTING: A rehabilitation facility in Chiang Mai, Thailand. METHODS: Data were obtained from medical records of patients who underwent cystometric evaluation at 6-12 months after TSCI...

PURPOSE: This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes. METHODS: We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered...

PURPOSE: We assessed the effectiveness and safety of using intravesical onabotulinumtoxinA (onabotA; BOTOX) injection with a low dose (75 units) for treating urinary storage symptoms in patients with detrusor overactivity with detrusor underactivity (DODU) compared to using the standard 100 units of onabotA in patients with overactive bladder (OAB).
