Abstract
PURPOSE The potential benefits of caffeine intake are currently receiving much attention and exploration. Urine flow rate (UFR) is an objective index to comprehensively reflect bladder function. The aim of this study was to investigate the association between caffeine intake and UFR using the National Health and Nutrition Examination Survey (NHANES) database. METHODS 14,142 participants were enrolled in this study. Weighted multivariate adjusted regression models were used to explore the relationship between caffeine intake and UFR. The dose-response relationships were explored using a restricted cubic spline (RCS) and a threshold effect analysis was conducted based on the inflection points identified by the two-segment linear regression model. In addition, subgroup analysis and sensitivity analysis were applied. RESULTS The findings suggested that the intake of caffeine was correlated with improved UFR [Model 3: 0.091 (0.057, 0.126), P value < 0.001]. In addition, the RCS supported a nonlinear relationship between them. The analysis of threshold effect further revealed a specific level of caffeine intake (34.51 mg/day) that exhibited a significant enhancement in UFR. Finally, through re-analyzing the data set obtained after multiple imputation (MI), we obtained similar results. CONCLUSION This study found a nonlinear beneficial relationship between caffeine intake and UFR, and revealed the recommended intake of caffeine. The values varied by gender, race, education, and smoking status.

Abstract
Concomitant use of sodium glucose cotransporter-2 inhibitors (SGLT-2i) and overactive bladder (OAB) drugs potentially poses a risk of urinary tract infections (UTIs) due to the urinary retention of highly concentrated glucose in the urine. Thus, this study aimed to investigate the risk of UTIs among patients who initiated SGLT-2i treatment while taking OAB drugs. This population-based cohort study included new-users of SGLT-2i or comparator antidiabetics (dipeptidyl peptidase-4 inhibitor (DPP-4i); glucagon-like peptide-1 receptor agonist (GLP-1RA)) with OAB drugs between 2014 and 2020 using claim data from Korea. Primary outcome was a composite UTI event composite end point comprising pyelonephritis, cystitis, and urethritis, using both inpatient and outpatient diagnoses. Propensity score fine stratification was used to adjust for potential confounding factors. Weighted hazard ratios (HR) were calculated using the Cox proportional hazards model. In the first cohort, 796 and 9,181 new-users of SGLT-2i and DPP-4i with OAB drugs were identified, respectively. This study found a similar risk of UTIs in concomitant users of SGLT-2i and DPP-4i (weighted HR 1.08, 95% confidence interval: 0.88-1.32) with OAB drugs. In the second cohort, 2,387 and 280 new-users of SGLT-2i and GLP-1RA with OAB drugs were identified, respectively. Initiation of SGLT-2i while on OAB treatment was not associated with increased risk of UTI (0.89, 0.50-1.60), compared with initiation of GLP-1RA. These results show that the concomitant use of SGLT-2i with OAB drugs was not associated with an increased risk of UTI compared with the concomitant use of DPP-4i or GLP-1RA with OAB drugs.

Abstract
Purinergic signaling plays an important role in regulating bladder contractility and voiding. Abnormal purinergic signaling is associated with lower urinary tract symptoms (LUTS). Ecto-5'-nucleotidase (NT5E) catalyzes dephosphorylation of extracellular AMP to adenosine, which in turn promotes adenosine-A2b receptor signaling to relax bladder smooth muscle (BSM). The functional importance of this mechanism was investigated using Nt5e knockout (Nt5eKO) mice. Increased voiding frequency of small voids revealed by voiding spot assay was corroborated by urodynamic studies showing shortened voiding intervals and decreased bladder compliance. Myography indicated reduced contractility of Nt5eKO BSM. These data support a role for NT5E in regulating bladder function through modulation of BSM contraction and relaxation. However, the abnormal bladder phenotype of Nt5eKO mice is much milder than we previously reported in A2b receptor knockout (A2bKO) mice, suggesting compensatory response(s) in Nt5eKO mouse bladder. To better understand this compensatory mechanism, we analyzed changes in purinergic and other receptors controlling BSM contraction and relaxation in the Nt5eKO bladder. We found that the relative abundance of muscarinic CHRM3 (cholinergic receptor muscarinic 3), purinergic P2X1, and A2b receptors was unchanged, whereas P2Y12 receptor was significantly downregulated, suggesting a negative feedback response to elevated ADP signaling. Further studies of additional ecto-nucleotidases indicated significant upregulation of the nonspecific urothelial alkaline phosphatase ALPL, which might mitigate the degree of voiding dysfunction by compensating for Nt5e deletion. These data suggest a mechanistic complexity of the purinergic signaling network in bladder and imply a paracrine mechanism in which urothelium-released ATP and its rapidly produced metabolites coordinately regulate BSM contraction and relaxation.

Abstract
OBJECTIVE To identify psychometrically robust quality-of-life (QOL) outcome measures for evaluating QOL among people with neurogenic overactive bladder (OAB). STUDY DESIGN Electronic databases (CINAHL, EMBASE, MEDLINE, Scopus and Web of Science) were searched from inception to January 2023. Two independent reviewers participated in study screening, data extraction and quality appraisal. Studies were included if they validated at least one psychometric property of a QOL outcome measure among adults (age ≥ 18 years) with neurogenic OAB. The COnsensus-based Standards for selecting health status Measurement INstruments (COSMIN) checklist and Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool were used to evaluate the methodological quality and quality of evidence, respectively, for each included study. RESULTS Database searches identified 47 studies that tested the psychometric properties of 15 QOL measures in a total of 19,994 participants with stroke, spinal cord injury, Parkinson's disease or multiple sclerosis. The Incontinence Quality of Life Questionnaire (I-QOL), King's Health Questionnaire, Overactive Bladder Questionnaire and Qualiveen were the best validated measures, with strong reliability, validity and responsiveness. I-QOL was the most robust, cross-culturally administered and psychometrically strong measure. The COSMIN checklist indicated sufficient methodological quality for 70% of measures, and the modified GRADE tool indicated quality of evidence ranging from moderate (67%) to high (33%). CONCLUSIONS This review identified the I-QOL as a culturally diverse measure with robust reliability, validity and responsiveness for assessing QOL among people with neurogenic OAB. These findings are supported by studies with good methodological quality (COSMIN) and high-quality evidence (GRADE).

Abstract
This study was to investigate urinary beta 3-adrenoceptor concentration as a biomarker for overactive bladder (OAB) and predictor of treatment outcomes in women receiving the beta 3-adrenoceptor agonist mirabegron. The study comprised 50 women identified with OAB and 35 women considered as healthy controls. All women with OAB received daily dosage of 50 mg of mirabegron for 12 weeks. Bladder diaries, OAB-related questionnaires, and global response assessment scale (GRAS) data were collected. Urinary beta 3-adrenoceptor concentration was measured through enzyme-linked immunosorbent assay. All OAB-related questionnaires and GRAS indicated improved posttreatment urinary health. After mirabegron treatment, the frequency of micturition and urgency episodes decreased, but the urinary beta 3-adrenoceptor/creatinine (Cr) ratio increased. The urinary beta 3-adrenoceptor/creatinine ratio was identified as a sensitive biomarker for OAB with a confidence interval of 0.656 to 0.856 (p < 0.001). A negative correlation (- 0.431, p = 0.040) between this biomarker and health-related quality of life (HRQL) scores. The Beta 3-adrenoceptor/Cr levels increased significantly in the treatment-responsive group, while they remained unchanged in the unsatisfactory outcome group. This study shows that 12 weeks of mirabegron treatment improves OAB symptoms and HRQL. Furthermore, urinary beta 3-adrenoceptor concentration may be a diagnostic biomarker for OAB.

Abstract
OBJECTIVE To elaborate on the effect of sleep duration on urinary incontinence (UI), we investigated the association between sleep duration with the risk of UI from the National Health and Nutrition Examination Survey (NHANES) dataset. METHODS A cross-sectional survey of female participants aged 20years old and above were enrolled from the year 2007-2018. We performed weighted multivariable logistic regression models to assess the association between sleep duration and UI. RESULTS A total of 6838 female participants were included. Compared with sleep duration less than 6 hours, other sleep duration was found to be not significantly correlated with total UI, stress urinary incontinence, and mixed urinary incontinence in all three models Compared to sleep duration less than 6 hours, multivariate regression demonstrated that moderate sleep (6-8 hours) indicated a lower urgent urinary incontinence (UUI, odds ratio=0.764, 95% confidence interval=0.620-0.944, P = .013). Inadequate sleep (<6 hours) indicated a higher UUI (odds ratio=1.308, 95% confidence interval=1.060-1.614, P = .013) compared to moderate sleep duration (6-8 hours). The association might be modified by the family income-to-poverty ratio. CONCLUSION Inadequate sleep (<6 hours) was associated with a higher incidence of UUI. A moderate sleep duration (6-8 hours) was related to a lower rate of UUI. Further studies are warranted for clinical prevention and treatment guidance.

Abstract
INTRODUCTION Overactive bladder (OAB) is a common syndrome in adults. Current pharmacologic treatment includes antimuscarinic agents and β-3 adrenoceptor agonists. For non-responders to oral medication, intravesical injection of botulinum toxin A (BoNT-A) is an effective option. However, these treatments have potential adverse events and should be cautiously selected for appropriate patients. This review presents the recently published results of clinical trials and studies for patients with OAB and the underlying pathophysiology of OAB. Appropriate medical therapy based on pathophysiology of OAB is also presented. AREAS COVERED Literature search from Pubmed from 2001 to 2023 including clinical background, pharmacology, and clinical studies for OAB medications. EXPERT OPINION Treatment of OAB syndrome with any antimuscarinic or β-3 adrenoceptor agonist is feasible as a first-line approach. For patients with suboptimal therapeutic effect to full-dose antimuscarinics or mirabegron, combination with both drugs can improve efficacy. Intravesical BoNT-A 100-U injection provides therapeutic effects for refractory OAB. Patients who are refractory to initial pharmacotherapies should be investigated for the underlying pathophysiology; then an appropriate medication can be added, such as an α1-blocker or anti-inflammatory agents. Patient education about behavioral modification and therapies should always be provided with oral medication or BoNT-A injection for OAB patients.

Abstract
Background The urinary system serves as a crucial pathway for eliminating metallic substances from the body, making it susceptible to the effects of metal exposure. However, limited research has explored the association between metal mixtures and bladder function. This study aims to investigate the relationship between urinary metal mixtures (specifically barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, and tungsten) and urine flow rate (UFR) in the general population, utilizing multiple mixture analysis models. Methods This study utilizes data obtained from the National Health and Nutrition Examination Survey. After adjusting for relevant covariates, we assessed the correlations between metal mixtures and UFR using three distinct analysis models: weighted quantile sum (WQS), quantile g-computation (qgcomp), and Bayesian kernel machine regression (BKMR). Additionally, a gender-stratified analysis was conducted. Finally, we also performed sensitivity analyses. Results A total of 7,733 subjects were included in this study, with 49% being male. The WQS regression model, when fitted in the positive direction, did not yield any significant correlations in the overall population or in the male and female subgroups. However, when analyzed in the negative direction, the WQS index exhibited a negative correlation with UFR in the overall group (β = -0.078; 95% CI: -0.111, -0.045). Additionally, a significant negative correlation between the WQS index and UFR was observed in the female group (β = -0.108; 95% CI: -0.158, -0.059), while no significant correlation was found in the male group. The results obtained from the qgcomp regression model were consistent with those of the WQS regression model. Similarly, the BKMR regression model revealed a significant negative correlation trend between metal mixtures and UFR, with cadmium and antimony potentially playing key roles. Conclusion Our study revealed a significant negative correlation between urinary metal mixture exposure and mean UFR in US adults, with notable gender differences. Specifically, higher urinary levels of cadmium and antimony were identified as potential key factors contributing to the decrease in mean UFR. These findings significantly contribute to the existing knowledge on the impact of metal mixtures on bladder function and provide valuable insights for safeguarding bladder health and preventing impaired bladder function.

Abstract
To review the available data on non-surgical management for neurogenic lower urinary tract dysfunction (NLUTD) in patients with chronic spinal cord injury (SCI) and provide the most updated knowledge for readers. We categorized the bladder management approaches into storage and voiding dysfunction separately; both are minimally invasive, safe, and efficacious procedures. The main goals for NLUTD management are to achieve urinary continence; improve quality of life; prevent urinary tract infections and, last but not least, preserve upper urinary tract function. Annual renal sonography workups and regular video urodynamics examinations are crucial for early detection and further urological management. Despite the extensive data on NLUTD, there are still relatively few novel publications and there is a lack of high-quality evidence. There is a paucity of new minimally invasive and prolonged efficacy treatments for NLUTD, and a partnership between urologists, nephrologists and physiatrists is required to promote and ensure the health of SCI patients in the future.

Abstract
Obesity and hypertension are intimately linked due to the various ways that the important cell types such as vascular smooth muscle cells (VSMC), endothelial cells (EC), immune cells, and adipocytes, communicate with one another to contribute to these two pathologies. Adipose tissue is a very dynamic organ comprised primarily of adipocytes, which are well known for their role in energy storage. More recently adipose tissue has been recognized as the largest endocrine organ because of its ability to produce a vast number of signaling molecules called adipokines. These signaling molecules stimulate specific types of cells or tissues with many adipokines acting as indicators of adipocyte healthy function, such as adiponectin, omentin, and FGF21, which show anti-inflammatory or cardioprotective effects, acting as regulators of healthy physiological function. Others, like visfatin, chemerin, resistin, and leptin are often altered during pathophysiological circumstances like obesity and lipodystrophy, demonstrating negative cardiovascular outcomes when produced in excess. This review aims to explore the role of adipocytes and their derived products as well as the impacts of these adipokines on blood pressure regulation and cardiovascular homeostasis.

Inhibitory effects of vibegron, a β 3-adrenoceptor agonist, on the myogenic contractile and mechanosensitive afferent activities in an obstructed rat bladder. Eur J Pharmacol 2022; 933:175272. [PMID: 36108733 DOI: 10.1016/j.ejphar.2022.175272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 08/05/2022] [Accepted: 09/08/2022] [Indexed: 11/22/2022]
Abstract
To determine the role of β3-adrenoceptor agonists on bladder sensory facilitation related to bladder myogenic contractile activities in bladder hyperactivity, we investigated the effects of vibegron, a β3-adrenoceptor agonist, on the bladder and sensory function by evaluating cystometry and mechanosensitive single-unit afferent activities (SAAs), respectively, in a male rat model of bladder outlet obstruction (BOO). BOO was created by partial ligation of the urethra. Ten days after the surgical procedure, cystometric and SAA measurements were taken under two distinct conditions: a conscious-restrained condition, in which the bladder was constantly filled with saline, and a urethane-anesthetized condition involving an isovolumetric process with saline. For each measurement, vibegron (3 mg/kg) or its vehicle was administered intravenously after the data were reproducibly stable. In addition, the expression of β3-adrenoceptor and substance P (SP), a sensory neuropeptide, in the bladder was further evaluated following immunohistochemical procedures. Number of non-voiding contractions (NVCs) in cystometry was decreased after vibegron-administration, which was a significant change from vehicle group. Number of microcontractions and SAAs of Aδ- and C-fibers were significantly decreased by vibegron-administration. Furthermore, β3-adrenocepor and SP were co-expressed in the suburothelium layer of the bladder. These findings indicated that vibegron showed inhibitory effects on NVCs and microcontractions of the bladder, and SAAs of the Aδ- and C-fibers in BOO rats. The study suggested that vibegron can partly inhibit the mechanosensitive afferent transduction via Aδ- and C-fibers by suppressing bladder myogenic contractile activities in the rat bladder hyperactivity associated with BOO.

Drug-induced Urinary Retention: An Analysis of a National Spontaneous Adverse Drug Reaction Reporting Database. Eur Urol Focus 2022; 8:1424-1432. [PMID: 34275763 DOI: 10.1016/j.euf.2021.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 06/07/2021] [Accepted: 07/02/2021] [Indexed: 12/16/2022]
Abstract
BACKGROUND Numerous drugs have been associated with urinary retention (UR), but updated information on drugs that may induce UR is limited. OBJECTIVE To evaluate drug-induced UR using the Italian spontaneous adverse drug reactions (ADRs) reporting database. DESIGN, SETTING, AND PARTICIPANTS We selected all suspected spontaneous reports of drug-induced UR collected into the Italian spontaneous reporting system (SRS) database from its inception to June 30, 2019. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The Mantel-Haenszel χ2 test and the Mann-Whitney U test were performed for statistical comparisons of categorical and continuous variables, respectively. As a measure of disproportionality, we calculated the reporting odds ratios (RORs) with corresponding 95% confidence intervals using a statistical case/noncase methodology. RESULTS AND LIMITATIONS A total of 506 383 ADR reports were received in the Italian SRS database during the study period. Of these, 421 reports (0.1%) included UR-related ADRs, for a total of 497 suspected drugs. The median (interquartile range [IQR]) age of patients experiencing UR was 67 (47-77) yr. Overall, 174 (41.3%) ADR reports were considered serious. One-third of male patients experiencing UR suffered from benign prostatic hyperplasia, followed by diabetes mellitus (N = 58, 13.8%), and bladder-related disorders (N = 21, 5.0%). The median lag time between the start of drug treatment and UR onset was 7 (IQR 1-47.5) d. Overall, a statistically significant ROR was reported for 39 individual drugs, and for five (12.8%) of them (dapagliflozin, gabapentin, lithium, celecoxib, and piroxicam) UR was not described in their summary of product characteristics. Limitations include under-reporting and selective over-reporting of suspected ADRs and lacking information on the number of drug users. CONCLUSIONS A disproportionality analysis identified five potentially new UR signals for dapagliflozin, gabapentin, lithium, celecoxib, and piroxicam, requiring further evaluation. PATIENT SUMMARY In this analysis of the Italian spontaneous reporting system database, we found new urinary retention signals, requiring further evaluation, for dapagliflozin, gabapentin, lithium, celecoxib, and piroxicam.

Abstract
In the lower urinary tract, transient receptor potential (TRP) channels are primarily involved in physiological function, especially in cellular sensors responding to chemical and physical stimuli. Among TRP channels, TRP melastatin 8 (TRPM8) channels, responding to cold temperature and/or chemical agents, such as menthol or icilin, are mainly expressed in the nerve endings of the primary afferent neurons and in the cell bodies of dorsal root ganglia innervating the urinary bladder (via Aδ- and C-fibers); this suggests that TRPM8 channels primarily contribute to bladder sensory (afferent) function. Storage symptoms of overactive bladder, benign prostatic hyperplasia, and interstitial cystitis are commonly related to sensory function (bladder hypersensitivity); thus, TRPM8 channels may also contribute to the pathophysiology of bladder hypersensitivity. Indeed, it has been reported in a pharmacological investigation using rodents that TRPM8 channels contribute to the pathophysiological bladder afferent hypersensitivity of mechanosensitive C-fibers. Similar findings have also been reported in humans. Therefore, a TRPM8 antagonist would be a promising therapeutic target for bladder hypersensitive disorders, including urinary urgency or nociceptive pain. In this review article, the functional role of the TRPM8 channel in the lower urinary tract and the potential of its antagonist for the treatment of bladder disorders was described.

Abstract
Background Overactive bladder (OAB) affects 12 to 30% of the world’s population. The accompanying urinary urgency, frequency and incontinence can have a profound effect on quality of life, leading to depression, social isolation, avoidance of sexual activity and loss of productivity. Conservative measures such as lifestyle modification and pelvic floor physical therapy are the first line of treatment for overactive bladder. Patients who fail these may go on to take medications, undergo neuromodulation or receive injection of botulinum toxin into the bladder wall. While effective, medications have side effects and suffer from poor adherence. Neuromodulation and botulinum toxin injection are also effective but are invasive and not acceptable to some patients. Methods We have developed a novel transcutaneous spinal cord neuromodulator (SCONE™,) that delivers multifrequency electrical stimulation to the spinal cord without the need for insertion or implantation of stimulating electrodes. Previously, multifrequency transcutaneous stimulation has been demonstrated to penetrate to the spinal cord and lead to motor activation of detrusor and external urethral sphincter muscles. Here, we report on eight patients with idiopathic overactive bladder, who underwent 12 weeks of SCONE™ therapy. Results All patients reported statistically significant clinical improvement in multiple symptoms of overactive bladder, such as urinary urgency, frequency and urge incontinence. In addition, patients reported significant symptomatic improvements as captured by validated clinical surveys. Conclusion SCONE™ therapy represents the first of its kind therapy to treat symptoms of urgency, frequency and urge urinary incontinence in patients with OAB. Trial registration The study was listed on clinicaltrials.gov (NCT03753750).

Abstract
OBJECTIVE Magnetic stimulation (MS) provides a novel strategy for the treatment of urinary incontinence (UI), although its efficacy remains uncertain. This systematic review both evaluated the effects of MS treatment on UI and investigated its impacts on female patients' life quality. METHODS A review of the literature that was conducted in EMBASE, PubMed, Google Scholar, and the Cochrane Library (2016-2021) with the search terms; Incontinence of stress OR urge of urination OR Urinary incontinence mixed type. The search was carried out for all randomised controlled trials (RCTs) in English. A manual search has also been conducted for the reference lists of the studies found. Seven studies, with a total of 523 patients (475 patients with SUI), 12 urge urinary incontinence. The study included patients with (UUI) and 36 patients with mixed urinary incontinence (MUI). A total of 10 male patients were excluded from the study. In the included studies, The International Incontinence Questionnaire-Short Form was used to investigate the effects of MS therapy on UI symptoms (ICIQ-SF). RESULTS According to the literature review, MS is an effective therapy option for female patients with UI. Still, to establish the efficacy of MS in this area, more large-scale, high-quality RCTs with extended follow-up periods that use consistent stimulation modalities and evaluate comparable outcomes are needed. CONCLUSION MS treatment leads to an improvement in the symptoms of UI, in addition to an associated Improved quality of life for patients, without any reported side effects, while the longer-term treatment outcomes must be determined by long-term trials.

Abstract
BACKGROUND Although cholinesterase inhibitors (ChEIs) are the primary treatment for dementia, they are associated with overactive bladder (OAB), necessitating antimuscarinic use. Limited data exist regarding the risk of OAB across individual ChEIs in dementia. This study evaluated the risk of OAB associated with individual ChEIs in older adults with dementia. METHODS This was a new user retrospective cohort study using Medicare claims data involving Parts A, B, and D claims dataset from 2013 to 2015. The study included older adults (aged 65 and older) with a diagnosis of dementia using donepezil, galantamine, or rivastigmine. New ChEI claims were identified with a 6-month baseline washout period. Patients with OAB diagnosis or any antimuscarinic or mirabegron use in the baseline period were excluded. The primary outcome of interest was OAB diagnosis or prescription of antimuscarinics or mirabegron within 6 months of ChEI initiation. Multivariable cox proportional hazards regression with propensity scores (PS) as covariates and inverse probability of treatment weighting generated using generalized boosted models was used to assess the risk of OAB among donepezil, galantamine, and rivastigmine users. RESULTS The study included 524,975 older adults with dementia who were incident users of ChEIs (donepezil 80.72%, rivastigmine 16.41%, galantamine 2.87%). Overall, OAB diagnosis/antimuscarinic/mirabegron prescription was observed in 5.07% of the cohort within 6 months of ChEIs prescription. The Cox regression model with PS as covariate approach found that donepezil use increased the risk of OAB compared to rivastigmine (aHR, 1.13; 95% CI, 1.08-1.28; p < 0.0001). However, there was no differential risk of OAB between galantamine and rivastigmine. The findings were consistent with the generalized boosted models. CONCLUSIONS The study found that the risk of OAB varies across individual ChEIs with an increased risk of OAB with donepezil compared to rivastigmine. The study findings suggest the need to understand and manage medication-related morbidity in older adults with dementia.

Abstract
Pharmacological management of urinary incontinence (UI) is currently based on antimuscarinic and beta-3-agonist drugs. Botulinum toxin A detrusor injections represent an effective but more invasive alternative. This review covers the latest developments of the currently available drugs and the emerging compounds for the treatment of UI. Evidence shows that new antimuscarinics and beta-3-agonists with improved safety profiles may offer unique options to patients intolerant to currently available drugs. Combination therapy proved to be a non-invasive alternative for patients refractory to first-line monotherapy. Exciting advances are ongoing in the research to improve the efficacy/tolerability profile of botulinum toxin, through innovative routes of administration. Several new agents emerged from preclinical studies, some of which have now entered the clinical phase of development and could represent, in the coming years, a new way for the treatment of UI. Recent evidence on the existence of different overactive bladder phenotypes could be the key to tailored treatment. Rather than discovering new molecules, reaching the ability to identify the right drug for the right patient could be the real gamechanger of the future.

Abstract
Urinary incontinence (UI) is a bothersome symptom with population studies suggesting a prevalence of 13.1% in women and 5.4% in men. While a significant cohort of patients with this complaint may ultimately require surgical management to achieve complete continence, a number of non-surgical measures exist to improve symptoms and quality of life. A range of guidelines exist on this topic, including those published by the European Association of Urology (EAU), the International Continence Society (ICS), the American Urological Association (AUA) and the UK's National Institute for Health and Care Excellence (NICE). The aim of our study is to provide an overview of the initial assessment of patients with UI including history taking, examination and basic investigations. Our review outlines non-surgical management strategies for UI, including conservative measures, behavioral and physical therapies and drug treatment. We shall also examine the above guidelines and present a narrative overview of the literature surrounding the diagnosis and non-surgical management of urinary incontinence.

Abstract
BACKGROUND Acetylcholinesterase inhibitors (AChEIs) have been associated with an increased risk of starting antimuscarinic treatment to treat overactive bladder (OAB)-an example of a prescribing cascade. Limited comparative data exist regarding the prescribing cascade of antimuscarinics across individual AChEIs in older adults with dementia. OBJECTIVE This study examined the association between individual AChEI use and antimuscarinic cascade in older adults with dementia. METHODS We conducted a new user retrospective cohort study from January 2005 to December 2018 using data from the TriNetX electronic medical record database, a federated electronic medical records network in the US. The cohort included patients 65 years or older with a diagnosis of dementia using AChEIs (donepezil, galantamine, or rivastigmine). Individual AChEIs were identified with index dates from 1 January 2006 to 31 June 2018, with a 1-year washout period. The study excluded patients with any antimuscarinic use and OAB diagnosis 1 year before the AChEI index date. The primary outcome of interest was the prescription of antimuscarinics within 6 months of the AChEI index date. A Cox proportional hazard model was used to assess the association between individual incident AChEI use and antimuscarinic prescribing cascade after controlling for several covariates. RESULTS The study included 47,059 older adults with dementia who were incident users of AChEIs. Most of these patients were initiated with donepezil (83.1%), followed by rivastigmine (12.3%) and galantamine (4.6%). Overall, 8.16% of the study cohort had incident OAB diagnosis or antimuscarinic prescription. Antimuscarinics were initiated by 1725 (3.7%) older adults with dementia within 6 months of AChEI prescription, and cascade varied widely across individual agents-donepezil (3.9%), rivastigmine (2.6%), and galantamine (2.9%). Cox proportional hazard analyses revealed that donepezil users had an increased risk of receiving antimuscarinics (adjusted hazard ratio 1.55, 95% confidence interval 1.31-1.83) compared with rivastigmine. The findings were consistent in sensitivity analyses. CONCLUSION This study found that donepezil use is more likely to lead to antimuscarinic cascade than rivastigmine. Future studies are needed to determine the potential consequences of this cascade in dementia.

Abstract
Background: Polycyclic aromatic hydrocarbon (PAH) metabolites have received increasing attention because several of these organic substances are highly carcinogenic or mutagenic. Exposure to PAHs is associated with many harmful health effects; however, we are not aware of any study that has explored the exposure to PAHs and urinary conditions in the general population. The present work aimed to investigate the correlation among PAH and urine flow rate (UFR). Method: Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2009–2012 were used in our study. A total of 4172 participants and a total of nine PAH metabolites were examined. The UFR was measured as the amount of urine excreted in a period of time (mL/h). Several covariates were adjusted in linear regression models. Result: After adjusting for variables, the PAH metabolites in urine showed a significant correlation with UFR. Dose-dependent associations between PAH metabolites in the urine and UFR were also found. Higher quartiles of PAH metabolites in urine exhibited higher regression coefficients. Conclusion: Our study highlighted that PAH metabolites in urine had a strong association with decreased UFR in the US adult population. These findings support the possibility that PAH exposure is related to bladder dysfunction. Further prospective studies are warranted.

Abstract
OBJECTIVE This is a follow-up study from a multicenter, prospective, before-and-after quasi-experimental, controlled trial to assess effectiveness at 36 months of an intervention designed to promote the revision and deprescribing of mirabegron in primary care in patients with overactive bladder. METHODS Intervention included patients who attended in 17 PHCs located in North Barcelona; control included patients who attended in the other 34 PHCs located in South, East and West Barcelona. The primary endpoint was mirabegron review and deprescribing when GPs considered appropriate, which was measured by the percentage of change of the number of patients with treatment at 36 months compared to the baseline. The intervention consisted of meetings with all the directors of the PHCs; distribution of the infographic to the GPs; providing information regarding the intervention for urologist and gynaecologist; and review of the treatments by the GPs. A monthly follow-up was done during the first year, and every three months thereafter until month 36. RESULTS Overall, 1932 patients were included, mean age 71.6 years (female 53.8%). A total of 540 patients included in the intervention discontinued mirabegron at some point during the 36 months follow-up (540/762, 70.8%) compared to 759 patients in the control (759/1170, 64.9%), (p < 0.001). A total of 324/433 patients (74.8%) who discontinued mirabegron use at 12 months remained without pharmacological treatment at 36 months. With respect to the baseline cohort, there was a lower introduction of new patients with mirabegron in the intervention (546/762, 71.6%) compared to the control (1246/1170, 106.5%), (p < .001). Regarding the treated patients, there was an increase of 41.6% in the control and a slight increase of 0.8% in the intervention at 36 months, (p < .001). CONCLUSION Our data indicate that an intervention can enhance the review use of mirabegron in the primary care setting, and promote their deprescribing.

Abstract
Urinary incontinence of idiopathic nature is a common complication of bladder cancer, yet, the mechanisms underlying changes in bladder contractility associated with cancer are not known. Here by using tensiometry on detrusor smooth muscle (DSM) strips from normal rats and rats with bladder cancer induced by known urothelial carcinogen, N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN), we show that bladder cancer is associated with considerable changes in DSM contractility. These changes include: (1) decrease in the amplitude and frequency of spontaneous contractions, consistent with the decline of luminal pressures during filling, and detrusor underactivity; (2) diminution of parasympathetic DSM stimulation mainly at the expense of m-cholinergic excitatory transmission, suggestive of difficulty in bladder emptying and weakening of urine stream; (3) strengthening of TRPV1-dependent afferent limb of micturition reflex and TRPV1-mediated local contractility, promoting urge incontinence; (4) attenuation of stretch-dependent, TRPV4-mediated spontaneous contractility leading to overflow incontinence. These changes are consistent with the symptomatic of bladder dysfunction in bladder cancer patients. Considering that BBN-induced urothelial lesions in rodents largely resemble human urothelial lesions at least in their morphology, our studies establish for the first time underlying reasons for bladder dysfunction in bladder cancer.

Abstract
Lower urinary tract dysfunction (LUTD) is a common health challenge in dementia patients with significant morbidity and socioeconomic burden. It often causes lower urinary tract (LUT) symptoms, restricts activities of daily life, and impairs quality of life. Among several LUT symptoms, urinary incontinence (UI) is the most prominent storage symptom in the later stages of dementia. UI in patients with dementia results not only from cognitive impairment, but also from urological defects such as detrusor overactivity. Management of LUTD in patients with dementia is based on multiple factors, including cognitive state, functional impairment, concurrent comorbidities, polypharmacy and urologic condition. Behavioral therapy under caregiver support represents appropriate treatment strategy for UI in these patients. Pharmacological treatment can be considered in patients refractory to behavioral therapy, but it is more effective when combined with behavioral therapy. Antimuscarinics and mirabegron, a beta-3 receptor agonist, are effective for managing storage symptoms involving the LUT. However, anticholinergic side effects in elderly subjects are a concern, particularly when there is a risk of exacerbating cognitive impairment with prolonged use of antimuscarinics. Proper recognition and treatment of LUTD in dementia can improve quality of life in these patients.

Abstract
Underactive bladder (UAB) is a symptom complex suggestive of detrusor underactivity (DU). Although it implies a primary dysfunction of the detrusor muscle, many other conditions such as advanced age, neurogenic factors, and bladder outlet obstruction also lead to UAB. The current understanding of the pathophysiology directly leading to UAB is limited. We believe that by identifying the morphological changes associated with UAB might shed light on this. Therefore, we searched literature with keywords of electron microscopy, ultrastructure, UAB, and DU to review current ultrastructural evidence concerning UAB.

Abstract
INTRODUCTION Overactive bladder is a prevalent symptom complex that affects the patient's quality of life. Any disruption between the neuronal micturition pathway can lead to bladder overactivity. Neurogenic causes, myogenic causes, aging, bladder outlet obstruction, sex, and psychological factors are some of the factors contributing to bladder overactivity. The complaint of any symptoms of OAB, which is highly prevalent and affects overall QOL, often needs therapeutic interventions. When conservative therapy methods fail, the addition of medications is recommended. The most commonly used agents for the treatment of OAB are antimuscarinic drugs. New classes of drugs, such as beta-3 agonists, have enriched our pharmacologic armamentarium. AREAS COVERED In this review, with a special focus on oral pharmacological treatments, we discussed the definition, etiology, symptoms, diagnosis, and management of OAB. EXPERT OPINION OAB is a multifactorial condition with every patient presenting with a different collection of symptoms and signs. Medical therapies should be given in conjunction with behavioral therapies. Using high or low doses, flexible doses, and stopping or changing the medications are interchangeable strategies based on the level of treatment efficacy and patient satisfaction.

Abstract
Background Lower urinary tract symptom (LUTS) is a common condition in older men. In accordance with the Dutch College of General Practitioners Guideline “Micturition symptoms in men”, the diagnosis can be made based on a patient’s medical history and a physical examination. GPs lack additional tools in primary care to assess the residual urine volume. A residual volume usually requires a referral to a urologist. We hypothesized that the IPSS screening questionnaire score (measuring the severity of symptoms) might be related to patients’ residual urine volume. The research objective was to examine the relation between the IPSS score and the residual urine volume. Methods In a cross-sectional study, we analysed patients’ IPSS and residual urine volume. Men aged over 50 with LUTS who consulted Dutch primary-care physicians were included. The interventions comprised an IPSS screening and a bladder scan. Data regarding the patients’ residual volume, total IPSS score, single IPSS score, IPSS storage score, and IPSS voiding score were recorded and analysed. We used odds ratios to describe the relation between the IPSS categories associated with the presence of a normal or abnormal (above 100 cc and above 200 cc) residual urine volume. Results A total of 126 patients were included in this study. Patients with higher scores on the overall IPSS, separate IPSS, IPSS storage and IPSS voiding showed no higher odds ratios of having an abnormal residual volume, neither above 100 mL or 200 mL. Conclusion We did not find a relation between the IPSS core to an abnormal residual urine volume in men aged over 50 with LUTS consulting primary-care physicians. Trial Registration This study has been approved by the Central Committee on Research Involving Human Subjects for the Arnhem-Nijmegen Region and is registered with ToetsingOnline under ID number 29822.091.10.

Abstract
Solifenacin (Sol), an antimuscarinic agent has been widely used for the treatment of overactive bladder. Transdermal formulations can be administered without water as well as absorbed slowly into the blood over a long period of time. The aim of this study was to develop cream and tape formulations of Sol, and evaluate the transdermal permeation and absorption of the drug from the two formulations in vitro and in vivo, respectively. In the preparation of cream formulation, Sol succinate was dissolved in purified water, and the mixture was added to the hydrophilic cream. Then, aqueous sodium hydroxide was added to the cream. In the tape formulation, Sol succinate was dissolved in a solvent with propylene glycol, diisopropanolamine, triethyl citrate, and EUDRAGIT E100. The dissolved solvent was poured onto a polyethylene film. Cream (5%) and tape (15%) formulations demonstrated high skin permeability. Addition of an adsorption enhancer (N-methyl-2-pyrrolidone) did not further increase the level of skin permeability. In subsequent in vivo experiments in rats, both the cream and tape formulations led to slow absorption of Sol into plasma, with increased t1/2 compared with oral administration. Plasma Sol concentrations peaked 24 h after transdermal application and the drug was still detectable in plasma 72 h after application. Additionally, the cream (5%) and tape (15%) formulations resulted in a higher area under the plasma concentration vs. time curve from 0 to 72 h (AUC0-72) compared with oral formulation (30 mg/kg). In conclusion, significant in vitro permeability and in vivo absorption of Sol from the transdermal formulations were observed.

Abstract
BACKGROUND Patients with dementia commonly suffer from symptoms of overactive bladder (OAB); however, limited research exists on the clinical impact of coexisting OAB among patients with dementia. As such, the objective of this study was to examine the impact of OAB on clinical outcomes, health-care resource use, and associated costs among patients with dementia. METHODS We conducted a retrospective cohort analysis of patients with dementia using 3861 matched pairs of patients with and without OAB. Analyses were based on administrative claims data from January 1, 2007, to September 30, 2015, and compared clinical outcomes, health services use, and associated costs. RESULTS Patients with dementia and OAB were more likely than those without OAB to have least one fall (incidence rate ratio [IRR]: 1.43, 95% confidence interval [CI], 1.22-1.68, P < .001), fracture (IRR: 1.23, 95% CI, 1.05-1.44, P = .008), combined fall/fracture (IRR: 1.25, 95% CI, 1.11-1.42, P < .001), or urinary tract infection (IRR: 2.75, 95% CI, 2.55-2.96, P < .001). Patients with dementia and OAB demonstrated greater utilization of all-cause encounter types compared to similar patients without coexisting OAB (P < .01). All-cause and dementia-related total health-care costs were approximately 23% (95% CI, 0.19-0.28, P < .001) and 13% (95% CI, 0.05-0.20, P = .001), respectively, greater than similar patients without coexisting OAB. CONCLUSION Coexisting OAB was associated with impacts on clinical outcomes, health-care resource utilization, and costs in patients with dementia.

Abstract
Contractile behaviour of the urinary bladder and its sympathetic inhibition during storage phases are not well understood. Here, we explore muscularis mucosae (MM) as a predominant mucosal contractile element and the capability of sympathetic nerves to relax detrusor smooth muscle (DSM) or MM. Distribution of α-smooth muscle actin (α-SMA)-immunoreactive cells was compared in pig, human, guinea pig, rat and mouse bladders by immunohistochemistry, while contractility of the bladder mucosa was compared in these species by isometric tension recordings. In pig, human and guinea pig bladders, DSM and MM located in the lamina propria expressed α-SMA immunoreactivity, while both rat and mouse bladders lacked a MM. Consistent with this presence or absence of MM, bladder mucosa of pig, human and guinea pig but not rat and mouse developed spontaneous phasic contractions (SPCs). Distribution of tyrosine hydroxylase (TH)-immunoreactive sympathetic nerve fibres was compared in pig DSM, MM, trigone and urethra, as were their sympathetic nerve-evoked contractile/relaxing responses examined. In pig DSM or MM, where TH-immunoreactive sympathetic fibres exclusively projected to the vasculature, sympathetic relaxations were difficult to demonstrate. In contrast, sympathetic contractions were invariably evoked in pig trigone and urethra where the smooth muscle cells receive TH-immunoreactive sympathetic innervations. Thus, SPCs of bladder mucosa appear to predominantly arise from the MM displaying species differences. Despite the currently accepted concept of sympathetic nerve-mediated DSM relaxation during the storage phase, it is unlikely that neurally released noradrenaline acts on β-adrenoceptors to relax either DSM or MM due to the anatomical lack of sympathetic innervation.

Abstract
Abnormalities in purine availability or purinergic receptor density are commonly seen in patients with lower urinary tract symptoms (LUTS), but the underlying mechanisms relating altered receptor function to LUTS are unknown. Here we provide extensive evidence for the reciprocal interplay of multiple receptors responding to ATP, ADP (adenosine diphosphate), and adenosine, agonists that regulate bladder function significantly. ADP stimulated P2Y12 receptors, causing bladder smooth muscle (BSM) contraction, whereas adenosine signaling through potentially newly defined A2b receptors, actively inhibited BSM purinergic contractility. The modulation of adenylyl cyclase-cAMP signaling via A2b and P2Y12 interaction actively regulated bladder contractility by modulating intracellular calcium levels. KO mice lacking the receptors display diametrically opposed bladder phenotypes, with P2Y12-KO mice exhibiting an underactive bladder (UAB) phenotype with increased bladder capacity and reduced voiding frequency, whereas A2b-KO mice have an overactive bladder (OAB), with decreased capacity and increased voiding frequency. The opposing phenotypes in P2Y12-KO and A2b-KO mice not only resulted from dysregulated BSM contractility, but also from abnormal BSM cell growth. Finally, we demonstrate that i.p. administration of drugs targeting P2Y12 or A2b receptor rescues these abnormal phenotypes in both KO mice. These findings strongly indicate that P2Y12 and A2b receptors are attractive therapeutic targets for human patients with LUTS.

Abstract
INTRODUCTION Overactive bladder (OAB) affects adults of all ages. The risk for medication-related adverse events (AEs) may differ between age groups, given age-related changes in pharmacokinetics and pharmacodynamics. No previous study has differentiated the risk of AEs between older and non-older adults with OAB. OBJECTIVE Our objective was to assess the risk of AEs and treatment discontinuations between older and non-older adults with OAB initiated on an antimuscarinic. METHODS We searched MEDLINE (PubMed interface), Embase, SCOPUS, and Cochrane Central Register for Controlled Trials in a previous analysis in February 2015 and repeated the search in August 2018, with no additional studies identified. Studies that delineated AEs or treatment discontinuations between the older and non-older (age <65 years) subjects were included. RESULTS Six studies that made nine comparisons between older and non-older subjects met the inclusion criteria. The AEs of dry mouth (46.7%), constipation (10.3%), and headache (7.7%) were most frequently reported. Older subjects were more likely to experience dry mouth (relative risk [RR] 1.09; 95% confidence interval [CI] 1.00-1.19), constipation (RR 1.92; 95% CI 1.52-2.43), dizziness (RR 2.37; 95% CI 1.21-4.62), and urinary retention (RR 4.17; 95% CI 1.76-9.89) than were non-older subjects. Headache was less likely to occur in older subjects (RR 0.58; 95% CI 0.40-0.86). Treatment discontinuations due to AEs were more likely to occur in the older subjects (RR 1.59; 95% CI 1.20-2.11). CONCLUSION Treatment of OAB with antimuscarinics in the older population resulted in significantly higher rates of AEs, barring headache, when compared with non-older subjects.

Abstract
Background/aim This study aimed to perform a limited observational study to ascertain whether there is statistical support that nocturnal enuresis (NE) is a predisposing factor in the development of overactive bladder (OAB). Materials and methods The authors recruited patients diagnosed with OAB over a period of twelve months, and those who declared a history of NE were asked additional questions regarding the features of their NE. Results A total of 285 patients were diagnosed with overactive bladder, and 98 (34.38%) of them had previously displayed NE symptoms that had diminished before reaching the median age of 9.83. Separation of patients by sex revealed a male majority (58.16%). Additionally, most patients had urban origins (75.51%). The median time span from remission of NE to diagnosis of OAB was 24.79 years, and the median age at which patients began to suffer was 31.80 years. Behavioral factors (smoking, alcohol consumption) and psychological and infectious factors (past history of urinary tract infection) were identified at varying degrees. Conclusion The presence of NE in a third of the patients who developed over time OAB and the earlier onset of OAB for these patients suggests a causal physiopathological relationship between NE and OAB. The preponderance of urban patients confirms the existence of acquired urban triggering factors of OAB (nutritious, social, or professional).

Abstract
RESUMO Objetivou-se avaliar a eficácia dos exercícios perineais, da eletroestimulação transcutânea do nervo tibial posterior (ETNTP) e da oxibutinina em mulheres com síndrome da bexiga hiperativa, que é a segunda causa mais comum de incontinência urinária, com sintomas urinários extremamente incômodos que prejudicam a qualidade de vida. Foram randomizadas 65 mulheres, das quais 57 completaram o tratamento. Formaram-se três grupos: o de exercícios perineais, ETNTP e o grupo controle, que utilizou oxibutinina. Os exercícios foram realizados em grupo, nas posições em pé, supino e sentado, duas vezes por semana, com duração de 30 minutos cada sessão, totalizando 12 sessões. Na ETNTP utilizou-se eletrodo transcutâneo posicionado em maléolo medial e outro 10cm acima, com frequência de 10Hz e largura de pulso de 200 microssegundos, por 30 minutos, duas vezes por semana, totalizando 12 sessões. Na medicação as pacientes receberam oxibutinina de 10mg/dia de liberação imediata divididos e duas doses de 5mg/dia, durante 12 semanas consecutivas. Antes e depois dos tratamentos, as pacientes passaram por uma avaliação composta pela análise do diário miccional, avaliação funcional do assoalho pélvico e aplicação de questionário de qualidade de vida OAB-V8. Houve redução da incontinência de urgência em 50%, 70,5% e 41% nos grupos de exercício, ETNTP e oxibutinina, respectivamente, com significância estatística somente da eletroestimulação. As três modalidades de tratamento foram eficazes na melhora da qualidade de vida para a terapêutica em curto prazo, estatisticamente semelhantes entre si.

Abstract
β3 -Adrenoceptor agonists are used in the treatment of overactive bladder syndrome. Although the relaxant response to adrenergic stimulation in human detrusor smooth muscle cells is mediated mainly via β3 -adrenoceptors, the plasma concentrations of the therapeutic dose of mirabegron, the only clinically approved β3 -adrenoceptor agonist, are considerably lower than the EC50 for causing direct relaxation of human detrusor, suggesting a mechanism of action other than direct relaxation of detrusor smooth muscle. However, the site and mechanism of action of β3 -adrenoceptor agonists in the bladder have not been firmly established. Postulated mechanisms include prejunctional suppression of ACh release from the parasympathetic nerves during the storage phase and inhibition of micro-contractions through β3 -adrenoceptors on detrusor smooth muscle cells or suburothelial interstitial cells. Implications of possible desensitization of β3 -adrenoceptors in the bladder upon prolonged agonist exposure and possible causes of rarely observed cardiovascular effects of mirabegron are also discussed.

Abstract
Urinary incontinence is a common, often undertreated, condition that impacts millions of Americans. Primary care physicians are well equipped to diagnose and treat urinary incontinence. Key to successful treatment is accurately determining the type of incontinence that ails the patient and using patient-reported quality-of-life indicators to guide stepwise treatment.

Abstract
OBJECTIVE To review the literature regarding the efficacy and safety of mirabegron for the treatment of overactive bladder (OAB). DATA SOURCES A literature search was performed using MEDLINE (PubMed) prior to December 31, 2013, using the terms "mirabegron" and "randomized-controlled trial." STUDY SELECTION/DATA EXTRACTION All published, double-blind, randomized-controlled trials assessing mirabegron were included. Articles were reviewed and included if mirabegron was used as monotherapy and if the primary outcome analyzed drug efficacy. DATA SYNTHESIS The efficacy of mirabegron for the treatment of OAB has been demonstrated in the selected five randomized, placebo-controlled trials. The majority of these trials lasted 12 weeks and compared various doses of mirabegron with placebo and/or tolterodine extended-release (ER). Primary efficacy outcomes for the trials included mean number of micturitions per 24 hours and mean number of incontinence episodes per 24 hours. Included trials showed statistically significant reductions in both efficacy outcomes for various doses of mirabegron when compared with placebo. CONCLUSION Based on the trials reviewed, mirabegron has been efficacious in reducing mean number of micturitions and incontinence episodes per 24 hours, as well as in improving other secondary outcomes such as OAB symptoms and quality-of-life measures. Common adverse drug events seen with mirabegron include: hypertension, nasopharyngitis, urinary tract infections, headache, constipation, upper respiratory tract infection, arthralgia, diarrhea, tachycardia, abdominal pain, and fatigue. Given the efficacy and safety data currently available, mirabegron represents a reasonable alternative to antimuscarinics for patients with OAB. Future studies are needed to determine the utility of mirabegron for OAB in a variety of demographics.

Abstract
OBJECTIVE To investigate the efficacy and safety of noninvasive intravesical instillation of onabotulinum toxin-A (OBTX-A) through systematic review and meta-analysis. Recently, several studies of noninvasive intravesical instillation of OBTX-A have been published. However, its efficacy is not well validated yet compared to well-known efficacy of minimally invasive intravesical injection of OBTX-A. METHOD Systematic review and meta-analysis were performed to evaluate the efficacy of noninvasive intravesical instillation of OBTX-A in patients with overactive bladder and interstitial cystitis/bladder pain syndrome by measuring outcomes such as urgency episode per 72 hours, frequency per 72 hours, urgency urinary incontinence, voided volume (VV), postvoided residual volume, maximum flow rate, and patient perception of bladder condition. RESULT Six trials in 4 studies that compared instillation of OBTX-A and placebo involving 248 patients (121 experimental and 127 controls) were included for final data extraction. Instillation of OBTX-A significantly increased VV, with a mean difference of 38.48 (95% confidence interval: 76.05, 0.92) compared to the placebo group. However, other outcomes showed statistically insignificant changes. Major adverse events were not reported in the group receiving intravesical instillation of OBTX-A. CONCLUSION Intravesical instillation of OBTX-A showed limited efficacy with improvement of VV for treatment of overactive bladder or interstitial cystitis/bladder pain syndrome. More studies are needed to overcome the efficacy of current noninvasive bladder instillation of OBTX-A regarding effective drug transport.

Abstract
OBJECTIVES To develop a new tool to assess constraints due to urinary treatments in neurological patients. MATERIALS AND METHODS A prospective, monocentric study has been conducted from January to May 2017. Out-patients (multiple sclerosis, spinal cord injury, Parkinson disease) were included in a referral center if they had LUTS treatment for at least 3 months. To validate psychometric properties, we conducted a literature review, qualitative interviews, and discussion with a panel of six experts. Comprehension, acceptation, and pertinence were tested by a pilot study. A validation study, designed to calculate content validity, internal consistency reliability, and test-retest reliability [intraclass correlation coefficient (ICC)] has been conducted. The primary outcome was good psychometric properties defined with Cronbach's α > 0.7 and ICC > 0.7. RESULTS Comprehension, acceptation, and pertinence were excellent. Validation study showed a perfect content validity (r2 = 1) and excellent internal consistency reliability (Cronbach' α = 0.90). Total score was between 0 (best score) to 66 (maximal constraints). Test-retest reliability calculated using ICC was 0.81. Time to fill questionnaire was 4 min 20 s. The final version was composed by 22 items. CONCLUSION LUTS TCA is the first validated tool to assess constraints of urinary treatment and has excellent psychometric properties.

Abstract
PRACTICAL RELEVANCE When a cat is presented for evaluation of a problem behaviour, it is likely that the cat's wellbeing is negatively affected by the condition. In addition, the owners and any other animals around the cat may also be experiencing negative consequences. When managing these cases, it is important to consider all options (including behaviour modification, environmental changes, medications) that can help to reach an optimal solution. Medication cannot teach the cat how to behave or change a particular behaviour; it can, however, reduce arousal, excitability, reactivity and anxiety. RATIONALE The rationale for using psychoactive medications in behavioural medicine, or veterinary psychiatry, is to increase the wellbeing of the animal and to aid the owner and practitioner in managing problem behaviours. Medications should always be used as an adjunct to behavioural and environmental modification. CLINICAL CHALLENGES Many psychoactive medications cannot be used in the face of certain physical illnesses or concurrently with other medications. Some medications may also have side effects, not be effective at the recommended dose or have a paradoxical effect. Furthermore, success is reliant on the owner being able to administer the medication. AIMS This article aims to guide practitioners by discussing questions such as how to choose the appropriate medication, how to dose it and how long to use it. The psychoactive medications most commonly used in feline medicine are reviewed, as well as some that are newer or less common. EVIDENCE BASE Data for the use of medications in cats is limited, with just a small number of clinical-, species- and problem-directed studies available, and a few more case series and case reports. Where feline-specific research is not available, the authors have drawn upon research published in other species, such as humans, dogs and rats, as well as anecdotal reports and expert opinions.

Abstract
Purpose In this study, we aimed to explain the role of oxidative stress in women with overactive bladder (OAB) by investigating the levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG), a marker of oxidative DNA damage, and malondialdehyde (MDA), an indicator of lipid peroxidation. Materials and Methods A total of 90 women were included in the study: 45 female patients diagnosed with OAB at Hopa State Hospital Urology Polyclinic and 45 healthy women without any metabolic or neurologic disease. Levels of MDA and 8-OHdG were measured in 24-hour urine samples for all subjects. Results Urinary levels of MDA and 8-OHdG were significantly higher in the OAB group than in the control group (p<0.001). A significant positive correlation (p<0.001) was found between the measurements of 8-OHdG and MDA. Conclusions Oxidative stress may be important in the pathophysiology of OAB, because levels of 8-OHdG and MDA are increased. Increased levels of 8-OHdG may be due to damaged nuclear and mitochondrial DNA as a result of oxidative attacks caused by free radicals. Nevertheless, further randomized and prospective studies with larger patient populations are needed.

Abstract
Antimuscarinic agents are now widely used as the pharmacological therapy for overactive bladder (OAB) because neuronal (parasympathetic nerve) and non-neuronal acetylcholine play a significant role for the bladder function. In this review, we will highlight basic and clinical aspects of eight antimuscarinic agents (oxybutynin, propiverine, tolterodine, solifenacin, darifenacin, trospium, imidafenacin, and fesoterodine) clinically used to treat urinary dysfunction in patients with OAB. The basic pharmacological characteristics of these eight antimuscarinic agents include muscarinic receptor subtype selectivity, functional bladder selectivity, and muscarinic receptor binding in the bladder and other tissues. The measurement of drug-receptor binding after oral administration of these agents allows for clearer understanding of bladder selectivity by the integration of pharmacodynamics and pharmacokinetics under in vivo conditions. Their central nervous system (CNS) penetration potentials are also discussed in terms of the feasibility of impairments in memory and cognitive function in elderly patients with OAB. The clinical aspects of efficacy focus on improvements in the daytime urinary frequency, nocturia, bladder capacity, the frequency of urgency, severity of urgency, number of incontinence episodes, OAB symptom score, and quality of life (QOL) score by antimuscarinic agents in patients with OAB. The safety of and adverse events caused by treatments with antimuscarinic agents such as dry mouth, constipation, blurred vision, erythema, fatigue, increased sweating, urinary retention, and CNS adverse events are discussed. A dose-dependent relationship was observed with adverse events, because the risk ratio generally increased with elevations in the drug dose of antimuscarinic agents. Side effect profiles may be additive to or contraindicated by other medications.

Abstract
Ketamine abusers may develop ulcerative cystitis and severe lower urinary tract symptoms, which is a medical dilemma. Recently, researchers have found the endemic of ketamine-induced cystitis worldwide. The intravesical administration of liposome-encapsulated onabotulinumtoxinA (Lipotoxin) might facilitate the healing of the damaged urothelium from liposomes, and reduce the urinary symptoms by onabotulinumtoxinA-induced chemo-denervation. Using female Sprague-Dawley rats, we investigated the effects of Lipotoxin on ketamine-induced cystitis. Functional magnetic resonance imaging, metabolic cage study, and cystometry were conducted. Paraffin-embedded sections were stained. The bladder mucosa and muscle proteins were assessed through Western blotting. We observed that repeated intravesical Lipotoxin instillation could improve suburothelial hemorrhage, recover the urothelial tight junction and adhesion proteins (zonula occludens-1 and E-cadherin), ensure less substance P in the urothelium, inhibit the overexpression of inflammatory mediators (IL-6, TNF-α, nuclear NF-κB, and COX-2) in the detrusor, suppress the upregulation of the mucosal TRPV1 and detrusor M2-mAChR, and ameliorate bladder overactivity in the ketamine-treated rats. These data reveal the mechanisms underlying the action of Lipotoxin in ketamine-induced cystitis of rats, which provide a basis of Lipotoxin for further treating ketamine-induced cystitis in humans.

Abstract
BACKGROUND Despite several new medications being Food and Drug Administration-approved for overactive bladder (OAB) and new prescription drug payment programs, there are limited population-based data regarding OAB medication use among older adults. OBJECTIVES To examine: (1) impacts of new medications and $4 generic programs on time trends for OAB-related medication dispensing for older adults in the United States; (2) differences by age and sex; and (3) temporal changes in OAB-related medication payments. METHODS Using Truven Health Analytics' Medicare Supplemental Database (2000-2015), we analyzed OAB-related medication claims for 9,477,061 Medigap beneficiaries age 65-104. We estimated dispensing rates (per 1000 person-months), assessed dispensing trends using interrupted time-series methods, compared dispensing rates by age and sex, and summarized payment trends. RESULTS From 2000 to 2015, 771,609 individuals filled 13,863,998 OAB-related prescriptions. During 2000-2007, 3 new extended-release medications became available (tolterodine, darifenacin, solifenacin), leading to increases in overall OAB-related dispensing rates by 19.1 (99% confidence interval, 17.0-21.2), a 92% increase since 2000; overall rates remained stable during 2008-2015. By 2015, the most common medications were oxybutynin (38%), solifenacin (20%), tolterodine (19%), and mirabegron (12%). Dispensing rates peaked at age 90 (rate, 53.4; 99% confidence interval, 53.1-53.7). Women had higher rates than men at all ages (average ratewomen-ratemen, 22.0). The gap between upper and lower percentiles of medication payments widened between 2008-2015; by 2015, 25% of reimbursed dispensed prescriptions had total payments exceeding $250. CONCLUSIONS Medication-specific dispensing rates for OAB changed when new alternatives became available. Recent changes in utilization and cost of OAB medications have implications for clinical guidelines, pharmacoepidemiologic studies, and payment policies.

Abstract
Purinergic signalling plays an important role in the regulation of bladder smooth muscle (BSM) contractility, and P2X4 receptor is expressed in the bladder wall, where it may act by forming heteromeric receptors with P2X1, the major purinergic force-generating muscle receptor. To test this hypothesis, we examined mouse BSM contractile properties in the absence and presence of selective P2X1 (NF449 & NF279) and P2X4 antagonists (5-BDBD). These drugs inhibited BSM purinergic contraction only partially, suggesting the possibility of a heteromeric receptor. However, carefully controlled co-immunoprecipitation experiments indicated that P2X1 and P2X4 do not form physically linked heteromers. Furthermore, immunofluorescence staining showed that P2X4 is not present in mouse BSM per se, but in an unknown cellular structure among BSM bundles. To investigate whether deletion of P2X4 could impact voiding function in vivo, P2X4 null mice were characterized. P2X4 null mice had normal bladder weight and morphology, normal voiding spot size and number by voiding spot assay, normal voiding interval, pressure and compliance by cystometrogram, and normal BSM contractility by myography. In conclusion, these data strongly suggest that P2X4 is not present in mouse BSM cells, does not affect smooth muscle contractility and that mice null for P2X4 exhibit normal voiding function.
