Abstract
Overactive bladder in women is a common chronic condition of urinary storage, affecting a significant proportion of the population. It is defined as a symptom diagnosis that indicates lower urinary tract dysfunction, in which patients experience urinary urgency, with or without urge incontinence, usually accompanied by frequency and nocturia. The diagnosis and treatment of overactive bladder are straightforward and systematic in line with national and international guidelines. However, women are required to disclose their bladder symptoms, and be motivated to make changes to their lifestyle to see improvements. This article focuses specifically on idiopathic detrusor overactivity; its diagnosis, treatment and psychological effects on women. Healthcare professionals require an understanding of the pathophysiology and treatment rationale for the condition to ensure appropriate management strategies for patients presenting to primary and secondary care are implemented.

Abstract
Objectives To evaluate whether urodynamic investigation (UDI), the gold standard to assess refractory lower urinary tract symptoms (LUTS), is appropriate to select healthy volunteers with apparent normal lower urinary tract function as control subjects for comparative studies. Subjects and Methods 42 healthy subjects (22 women, mean age 32±10 years; 20 men, mean age 37±12 years) without LUTS were included into this prospective single-centre cohort study. All subjects recorded a 3-day bladder diary, completed validated questionnaires regarding LUTS, and underwent neuro-urological assessment as well as free uroflowmetry. Same session repeat UDI was performed according to “Good Urodynamic Practice” recommended by the International Continence Society, but using an air-charged instead of a water-filled catheter, and evaluated by a blinded investigator. Results All 3-day bladder diaries, LUTS questionnaires, neuro-urological assessments and free uroflowmetries were within normal limits. Overall (either during the first or second UDI), same session repeat UDI revealed pathological findings in 71% (30/42): Detrusor overactivity was detected in 14% (3/22) and 30% (6/20), post void residual >100mL in 14% (3/22) and 25% (5/20), bladder outlet obstruction in 9% (2/22) and 20% (4/20) and detrusor sphincter dyssynergia in 77% (17/22) and 65% (13/20) of our women and men, respectively. Repeatability of detrusor overactivity (κ = 0.78, 95% CI: 0.54–1.02) and detrusor sphincter dyssynergia (κ = 0.77, 95% CI: 0.55–0.98) showed substantial agreement between both UDIs. All other assessed urodynamic parameters had wide 95% limits of agreement for differences in the parameters indicating poor repeatability. Conclusions More than 70% of our healthy subjects showed pathological urodynamic findings. Although UDI is the gold standard to assess refractory LUTS, it seems not to be applicable in healthy subjects to define normal lower urinary tract function. Therefore, we do not recommend using UDI to select healthy control subjects.

Abstract
Overactive bladder syndrome affects millions of women in the U.S. and is defined by urinary urgency, urinary frequency, and small volume voids, with or without nocturia and incontinence. Overactive bladder is a diagnosis of exclusion, and several therapies exist for the management of this condition. This article outlines a systematic approach that the primary care physician can take when treating a patient with overactive bladder.

Abstract
Objective To compare the cost-effectiveness of bladder ultrasonography, clinical history, and urodynamic testing in guiding treatment decisions in a secondary care setting for women failing first line conservative treatment for overactive bladder or urgency-predominant mixed urinary incontinence. Design Model-based economic evaluation from a UK National Health Service (NHS) perspective using data from the Bladder Ultrasound Study (BUS) and secondary sources. Methods Cost-effectiveness analysis using a decision tree and a 5-year time horizon based on the outcomes of cost per woman successfully treated and cost per Quality-Adjusted Life-Year (QALY). Deterministic and probabilistic sensitivity analyses, and a value of information analysis are also undertaken. Results Bladder ultrasonography is more costly and less effective test-treat strategy than clinical history and urodynamics. Treatment on the basis of clinical history alone has an incremental cost-effectiveness ratio (ICER) of £491,100 per woman successfully treated and an ICER of £60,200 per QALY compared with the treatment of all women on the basis of urodynamics. Restricting the use of urodynamics to women with a clinical history of mixed urinary incontinence only is the optimal test-treat strategy on cost-effectiveness grounds with ICERs of £19,500 per woman successfully treated and £12,700 per QALY compared with the treatment of all women based upon urodynamics. Conclusions remained robust to sensitivity analyses, but subject to large uncertainties. Conclusions Treatment based upon urodynamics can be seen as a cost-effective strategy, and particularly when targeted at women with clinical history of mixed urinary incontinence only. Further research is needed to resolve current decision uncertainty.

Abstract
The pathophysiological mechanisms underlying overactive bladder syndrome (OAB) can include dysfunction of sensory pathways of the peripheral and central nervous systems, resulting in bladder hypersensitivity. Central sensitization describes an induced state of spinal hypersensitivity that is associated with a variety of chronic pain disorders that share many attributes with OAB, albeit without the presence of pain. As such, the concept of central sensitization might be relevant to understanding the mechanisms and clinical manifestations of OAB syndrome. An understanding of the pathophysiology and clinical manifestations of central sensitization, and the evidence that supports a role of central sensitization in OAB, including the potential implications of mechanisms of central sensitization for the treatment of patients with OAB could provide a novel approach to the treatment of patients with this disease. Such an approach would be especially relevant to those patients with central sensitization-related comorbidities, and has the potential to improve the outcomes of these patients in particular.

Abstract
AIM OF STUDY Urinary dysfunction in Creutzfeldt-Jakob disease (CJD) patients is attributed to functional incontinence, since they often have immobility and loss of motivation. In contrast, previously no urodynamic findings are available in CJD patients. CASE REPORT We had 2 CJD patients who had urinary frequency and urinary retention. We performed urodynamics with the spouse's informed consent in order to explore the mechanism of urinary dysfunction in those cases. Case 1 had typical acute cognitive deterioration with incontinence and urinary retention, while case 2 had subacute cognitive deterioration (that started after admission) and nocturia. The urodynamic findings were diverse. One feature was detrusor overactivity during bladder filling in case 1. Another feature of urodynamic finding includes neurogenic change of sphincter EMG in case 1 and decreased bladder sensation in case 2. CONCLUSION Urodynamics in our two CJD patients revealed detrusor overactivity and neurogenic sphincter electromyogram, presumably reflecting pathological lesions in the prefrontal cortex/basal ganglia as well as the sacral spinal cord in CJD.

Abstract
INTRODUCTION Intravesical botulinum toxin (BoNT-A) is a safe and effective treatment for overactive bladder syndrome. There are many reports on the clinical experience with BoNT-A, especially in patients with neurogenic detrusor overactivity. The US Food and Drug Administration has recently approved its use for idiopathic overactive bladder (iOAB). Various studies have reported positive results for iOAB in the short-term. Yet little is known about the results after repeated BoNT-A injections. In this study, we evaluated the long-term results of botulinum toxin (BoNT-A) in women with iOAB. METHODS Patients treated with BoNT-A from 2004 until 2009 were evaluated in a non-academic teaching hospital (Zuyderland MC, Heerlen, the Netherlands). All female patients with a follow-up of >5 years with idiopathic bladder dysfunction were included. All patients received 200 U of onabotulinum toxin-A in 20 intradetrusor injections. In some patients, we applied a dose adjustment for repeated injections. Patients were instructed how to use clean intermittent self-catheterization (CISC) before the treatment. We advised patients to commence CISC if post-void residual exceeded 150 ml. RESULTS A total of 128 women were included. All patients had at least 5-year follow-up after their first injection. The mean follow-up was 97 (60-125) months. The mean age was 67 (46-88) years. Of all patients, 30 % were still on BoNT-A treatment at the last follow-up visit. Of the 70 % that discontinued treatment, 27 % had insufficient effect and 43 % had tolerability issues. Most patients discontinued treatment after the first (79 %) and second (19 %) injections. Only 2 % of patients discontinued treatment after more than two injections during follow-up. CONCLUSION Intravesical BoNT-A is an effective treatment for women with idiopathic OAB. However, in time, almost two-thirds of patients in our study discontinued therapy. Most patients discontinue treatment after one or two injections and mainly due to tolerability issues.

Abstract
INTRODUCTION Urinary urgency is a hallmark symptom of overactive bladder (OAB). Several scales have been used to measure urgency. Taking into account the exceptional importance of these scales, it is important to determine their reliability, which depends directly on the accuracy of the wording and clarity to patients. AIM To determine reliability of Russian-language translation of the Patient Perception of Intensity of Urgency Scale (PPIUS) in identifying and assessing urgency in patients with OAB. MATERIALS AND METHODS The study included 50 patients (46 women and 4 men) aged 19 to 70 years (mean age 56.5 years). At the time of entering the study, all patients had symptoms of OAB and received anticholinergic therapy for at least 3 months with any drug approved for the use in Russia. PPIUS scale validation was performed by assessing reliability, absence of "habituation" effect of and indicators of convergent, divergent, and content validity. RESULTS The Russian version of voiding diary with PPIUS scale was found to have good psychometric properties and besides the content validity also had significant signs of convergent and divergent validity. CONCLUSION The Russian-language versions of urgency scales PPIUS and TUFS can be considered validated for using in clinical practice and in clinical and non-interventional studies in patients with OAB in Russia.

Abstract
PURPOSE We compare the systemic (nonurological) symptoms between patients with overactive bladder and subjects without overactive bladder. We also compare the urinary symptoms, quality of life and psychosocial measures between the 2 subgroups of patients with overactive bladder with a high vs low systemic symptom burden. MATERIALS AND METHODS Patients diagnosed with overactive bladder (51) and age matched individuals without overactive bladder (30) were administered the polysymptomatic, polysyndromic questionnaire to assess the numbers and distribution of systemic symptoms across multiple organ systems. Validated instruments were administered to evaluate urinary symptoms (ICIQ-UI, ICIQ-OAB, OAB-q, USS), quality of life (UDI-6, IIQ-7, OAB-q) and psychosocial difficulties (depression, anxiety, stress, sexual trauma, sleep, fatigue). Patients with overactive bladder were divided into 2 subgroups (with and without widespread systemic symptoms) and their responses were compared. RESULTS Patients with overactive bladder reported significantly more systemic (nonurological) symptoms compared to controls (mean ± SD 17.5 ± 12.3 vs 6.4 ± 7.9 symptoms, p <0.001). Differences were observed across multiple organ systems (neurologic, cardiopulmonary, gastrointestinal, sexual, musculoskeletal and gynecologic, p <0.05). About a third of patients with overactive bladder (31.4%) reported widespread systemic symptoms across multiple organ systems (mean 32.0 symptoms). The presence of widespread systemic symptoms among patients with overactive bladder was correlated with worse incontinence/overactive bladder symptoms (ICIQ-UI, OAB-q), poorer quality of life (UDI-6, IIQ-7, OAB-q) and more psychosocial difficulties (depression, anxiety, fatigue and higher stress, p <0.05). CONCLUSIONS The increased presence of nonurological symptoms in overactive bladder suggests an underlying systemic etiology and pathogenetic mechanisms that may contribute to overactive bladder. This study highlights the importance of understanding systemic factors in urological conditions otherwise thought to be organ specific.

Abstract
We investigated the influence of nocturia and sleep disturbance on health-related quality of life(HRQOL) using the Medical Outcomes Study 8-item Short Form Health Survey (SF-8) in patients with nocturia. We also assessed the effect of therapeutic intervention by means of an anticholinergic agent on the results of the SF-8. One hundred and eighty-four patients who voided at least once per night were surveyed using the SF-8, Overactive Bladder Symptom Score (OABSS), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS). These parameters were also evaluated before and after 12 weeks of imidafenacin treatment in 51 patients with OAB accompanied by nocturia. The SF-8 physical component summary score (PCS) showed a significant decrease as nighttime voiding frequency increased. The mental health component summary score was 47.1 and 47.6 (which were lower than the standard value of 50) in the group with a nighttime frequency of once and ≥3/night, respectively. The SF-8 PCS and 6 subscales were negatively associated with nighttime voiding frequency, while the PSQI global score was positively associated with it. Imidafenacin significantly improved the OABSS, PSQI, and ESS, as well as the SF-8 score. This is the first study using the SF-8 to show that nocturia and sleep disturbance have a major influence on comprehensive HRQOL and that the SF-8 can be used to monitor HRQOL in OAB patients receiving treatment for nocturia.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of this study was to evaluate for any association between pretreatment cystometry results and outcome of treatment with mirabegron in women with overactive bladder (OAB) symptoms. METHODS This was a prospective observational study of women with OAB symptoms that proved refractory to conservative management. All women underwent filling and voiding subtraction cystometry prior to further treatment. Women were treated with mirabegron 50 mg once daily, and outcomes were evaluated after 6 weeks' treatment. The primary outcome measure was change in symptoms as indicated by response to the Patient Global Impression of Improvement (PGI-I) scale. The presence of detrusor overactivity (DO), the highest detrusor pressure recorded during the filling phase, the presence of urodynamic stress incontinence (USI), cystometric capacity, voided volume, maximum flow rate and detrusor pressure at maximum flow were all compared between responders and nonresponders. RESULTS The study population consisted of 169 women; response rate to mirabegron was 69.8 %. There was no association between the presence of DO or maximum detrusor pressure during filling and USI, cystometric capacity, maximum flow rate and detrusor pressure at maximum flow and treatment response. In a subgroup with OAB symptoms refractory to previous treatment with antimuscarinics, there was an association between the presence of DO and a positive treatment response (p = 0.02). CONCLUSIONS Overall, there is no association between urodynamic findings and response to treatment with mirabegron. This may reflect the fact that mirabegron's mode of action mechanisms are not measurable using cystometry. In women with refractory symptoms, however, the presence of DO is associated with a positive response to treatment.

Abstract
Overactive bladder (OAB) is a common condition in both women and men. Although prevalence's are similar in both genders, sex specific differences do exist in relation to individual OAB symptoms as well as degree of bother and quality of life. The added effect of prostatic enlargement in men leads to slightly different evaluation and treatment regimens in both genders. This review will examine the gender differences in OAB related to epidemiology, OAB evaluation, investigation and treatment. This information will assist the primary care physician in assessing and initiating treatment in patients with OAB. It will further the understanding of the spectrum of treatments available for OAB and assist in determining the appropriateness and timing of referral of such patients to a urologist.

Abstract
OBJECTIVES This study examined potential benefits of diagnosing and treating elderly adults with overactive bladder (OAB) symptoms. METHODS Data were analysed from the OAB Re-Contact Study (N = 2750), a cross-sectional, self-reported Internet survey. Elderly respondents (65+ years old) with OAB were identified according to current medication use to control OAB symptoms or by scores > 14 (men) or > 16 (women) on the OAB Awareness Tool. Treated were those currently using prescription medication and never treated were those who never used prescription medication for OAB. Outcome measures included health-related quality of life, activity impairment, OAB-related severity and symptoms, and healthcare resource use (e.g. hospitalisations). Generalised linear models predicted health outcomes as a function of diagnosis or treatment, adjusting for covariates. RESULTS Diagnosed vs. not diagnosed elderly respondents had higher mental component summary (MCS) scores and SF-6D health utilities, and less activity impairment. Treated vs. never treated elderly respondents had higher MCS and SF-6D health utilities, less activity impairment, fewer OAB symptoms, lower OAB Awareness Tool scores, and lower odds of having bladder problems or incontinence. There were no significant differences in healthcare resource use. Further analysis by age group (middle-aged vs. elderly respondents) revealed significantly greater diagnosis- and treatment-related benefits on MCS (2.93 and 4.49 points more, respectively) and activity impairment (1.24 and 1.37 times as much, respectively) among elderly respondents. CONCLUSIONS Diagnosis and treatment were each associated with a lower health burden for elderly adults with OAB symptoms. These findings highlighted the importance of diagnosis and treatment in alleviating OAB symptoms and their impact on health outcomes.

Abstract
BACKGROUND Overactive bladder (OAB) is defined by subjective symptoms such as urgency, frequency, and urge incontinence, rather than objective measures. Using questionnaires like OABSS can help in diagnosis and evaluation of patients'symptoms for further assessment. OBJECTIVE To evaluate test-retest reliability of OABSS in 2-week interval and to evaluate the correlation of OABSS with voiding diary, IPSS, and PPBC. MATERIAL AND METHOD Between August 2009 and January 2011, 56 Thai women aged more than 18 years, attending urogynecology clinic at King Chulalongkorn Memorial Hospital were recruited in the study. They were diagnosed as having the overactive bladder with these criteria, symptoms of urinary frequency, urgency with or without urge incontinence, for more than three months, and at least one episode of urgency with or without incontinence in last three days. After giving the written informed consents, the patients were instructed to complete the voiding diary before starting the study and at the second visit (two weeks apart). The Thai version of self-answered questionnaires (OABSS, IPSS, and PBC) were also given at 0- and 2-week visit. The questionnaires were translated by one linguist from the Language Institute, Chulalongkorn University, Thailand, and translated back by another linguist to English. The content and language validity were checked by one urogynecologist at our department. The study was conducted after the protocol was approval by the Institutional Review Board (IRB). RESULTS The test-retest reliabilities (intraclass correlation) of the OABSS, PPBC, and IPSS total score were 0.88, 0.44, and 0.85. The overall Cronbach's alpha of OABSS was 0.31 and 0.41 at 0- and 2-week respectively. CONCLUSION Thai version of OABSS was reliable, valid, and related to the abnormal voiding symptoms. Further use of Thai version OABSS questionnaire was advocated for both clinical study and clinical practice in Thai women with OAB.

Abstract
AIMS The clinical relevance of urethral pressure variations (UPV) in the pathophysiology of over active bladder syndrome (OAB) has remained controversial to date. Some studies report an association with OAB and/or detrusor over activity (DO). Recently the International Consultation on Incontinence-Research Society recommended new clinical research to be performed on this subject. We provide a systematic review of the literature to specify this recommendation. METHODS Literature search was performed in PubMed, Embase, Web of Science, Cochrane, Central, Cinahl, Academic Science Premier, Science Direct, and Wiley Online using a sensitive search string combination. All authors independently reviewed and scored full text papers and consensus about methodological quality was obtained according to Oxford Level of Evidence (LoE). RESULTS Four hundred eighty seven abstracts were screened, 25 papers met all predefined inclusion selection criteria. Incidence figures of UPV varied between 2% and 95%. Studies are of poor methodological quality with Oxford LoE scores of 3B and 4. Measurement methods and techniques show a large variety. The above mentioned association of DO/OAB with UPV is however frequently reported. CONCLUSION There exists a phenomenon of UPV, apart from DO, which may be a separate entity within OAB syndrome. Large variation in measurement techniques and patient populations hinders fundamental research as well as clinical progress. Clinical relevance of UPV and consequences for treatment therefore are yet to be established. Future prospective research with well-defined patient population and standardised urodynamic measurement techniques is needed. Results of standardized and objective evaluations should be compared to clinical signs and symptoms by validated questionnaires. Neurourol. Urodynam. 36:51-56, 2017. © 2015 Wiley Periodicals, Inc.

Abstract
Purpose The association between menopause and overactive bladder is controversial. The purpose of this study was to determine the association between menopausal symptoms and overactive bladder, and identify the risk factors for overactive bladder. Methods A cross-sectional study was performed. The study included 403 women aged 36–76 years who visited the menopause clinic at Peking University First Hospital between September 2012 and December 2013. The overactive bladder symptom score and modified Kupperman index questionnaires were used. Differences were assessed using descriptive statistics to determine any association between the overactive bladder symptom score and modified Kupperman index score, and to evaluate the risk factors for overactive bladder. Results A total of 304 women were finally enrolled. The prevalence of overactive bladder was 9.43%, and the modified Kupperman index score; number of sexual problems; and frequency of urinary tract infections, vertigo, melancholia, and mood swings were significantly higher in patients with overactive bladder than in the patients without overactive bladder (p < 0.05). Menopausal symptoms (modified Kupperman index score ≥ 15) (odds ratio: 1.049, 95% confidence interval: 1.006–1.095, p = 0.025) and a low frequency of sexual intercourse in the last 6 months (odds ratio: 2.580, 95% confidence interval: 1.228–5.422, p = 0.012) were identified as independent risk factors for overactive bladder. The frequency of sexual intercourse was found to decrease with an increase in the severity of overactive bladder (p = 0.004, linear-by-linear association = 0.001). Conclusion Menopausal symptoms may be closely associated with overactive bladder, and sexual activity may be associated with the severity of overactive bladder. Moreover, sexual problems, urinary tract infections, vertigo, melancholia, and mood swings may be associated with overactive bladder.

Abstract
INTRODUCTION To develop and validate a lower urinary tract symptom score (LUTSS) as a measure of lower urinary tract symptom (LUTS) severity and a treatment outcome tool in adults. MATERIALS AND METHODS An expert panel was convened to develop the LUTSS questionnaire. Content validity was achieved by obtaining subject and expert feedback from two prospective drafts. Subjects were divided into three groups: normal, LUTS and overactive bladder (OAB). Questionnaire was administered on two separate occasions within 1-2 weeks. Test-retest reliability, internal consistency, discriminant validity, criterion validity and responsiveness to change were also assessed. RESULTS The questionnaire contains 14 questions with answers scored on a 5-point Likert scale (0-4). It includes 9 storage, 4 voiding and 1 bother question. One hundred ninety-one patients completed it; 80 males and 111 females, mean age 65 years (range 22-91). Seventy-two had OAB, 91 LUTS without OAB and 28 were normal. Test-retest intraclass correlation was 0.96 and Cronbach's-□ was 0.77, indicating strong test-retest reliability and internal consistency, respectively. ANOVA and post-hoc bootstrap-generated adjustments showed significant differences between the three groups (p < 0.001), demonstrating discriminant validity. Responsiveness to change was exhibited by the significant decrease between preop and postop scores and a concurrent patient global impression of improvement (PGI-I) score indicative of symptomatic improvement. CONCLUSION The 14-question LUTSS is a validated questionnaire that assesses a full range of LUTS in men and women. The ordinal nature of the data with its highly specific description of symptoms makes it ideally suited as a nuanced and comprehensive symptom score and patient reported outcome (PRO) tool.

Abstract
Case records of 1994 patients with injuries of the pelvic ring were analyzed. The article presents the results of examination and treatment of patients with urinary tract dysfunction. A frequent complications of pelvic fractures include overactive bladder syndrome (OAB) (18.9%). Many factors play a role in the development of this syndrome, in particular damage to the pelvic diaphragm and the development of pelvic hematoma. OAB is more common in unstable pelvic fractures (24.8%). Surgical stabilization of the pelvic ring injuries and the use of M-cholinoblockers and a1-blockers lead to a reduction of OAB.

Cost-Effectiveness of Mirabegron Compared with Antimuscarinic Agents for the Treatment of Adults with Overactive Bladder in the United Kingdom. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2015; 18:783-790.

Abstract
BACKGROUND Mirabegron, a first-in-class selective oral β3-adrenoceptor agonist, has similar efficacy to most antimuscarinic agents and a lower incidence of dry mouth in patients with overactive bladder (OAB). OBJECTIVES To evaluate the cost-effectiveness of mirabegron 50 mg compared with oral antimuscarinic agents in adults with OAB from a UK National Health Service perspective. METHODS A Markov model including health states for symptom severity, treatment status, and adverse events was developed. Cycle length was 1 month, and the time horizon was 5 years. Antimuscarinic comparators were tolterodine extended release, solifenacin, fesoterodine, oxybutynin extended release and immediate release (IR), darifenacin, and trospium chloride modified release. Transition probabilities for symptom severity levels and adverse events were estimated from a mirabegron trial and a mixed treatment comparison. Estimates for other inputs were obtained from published literature or expert opinion. Quality-adjusted life-years (QALYs) and total health care costs, including costs of drug acquisition, physician visits, incontinence pad use, and botox injections, were modeled. Deterministic and probabilistic sensitivity analyses were performed. RESULTS Base-case incremental cost-effectiveness ratios ranged from £367 (vs. solifenacin 10 mg) to £15,593 (vs. oxybutynin IR 10 mg) per QALY gained. Probabilistic sensitivity analyses showed that at a willingness-to-pay threshold of £20,000/QALY gained, the probability of mirabegron 50 mg being cost-effective ranged from 70.2% versus oxybutynin IR 10 mg to 97.8% versus darifenacin 15 mg. A limitation of our analysis is the uncertainty due to the lack of direct comparisons of mirabegron with other agents; a mixed treatment comparison using rigorous methodology provided the data for the analysis, but the studies involved showed heterogeneity. CONCLUSIONS Mirabegron 50 mg appears to be cost-effective compared with standard oral antimuscarinic agents for the treatment of adults with OAB from a UK National Health Service perspective.

Abstract
The treatment failure often happens in overactive bladder (OAB) partly owing to its unknown pathogenesis. The purpose of this study is to find significant receptors or biological markers for OAB-related symptoms for establishment of potential order-made therapeutic strategies. The overactive bladder symptom scores (OABSS) and international prostate symptom scores (IPSS)/quality of life (QOL) were questioned in all the 18 patients with OAB diagnosis. Their bladder mucosal tissues were taken from the random biopsy of bladder cancer suspected patients without any finding such as inflammation or carcinoma in situ. They were investigated quantitatively by immunohistochemical (IHC) stainings for inflammatory or immune-system (Interleukin (IL)-6 and cyclooxygenase-2 (Cox-2)), Caspase-3 apoptosis markers, angiogenesis (CD-31), epithelial-mesenchymal transition (E-cadherin) and muscarinic receptor (Muscarine-2 (M)-2), adrenergic receptors (ARs) (alpha 1-d (α1-d) and beta-3 (β-3)). The statistical correlation between the expressions of these 5 markers and 3 receptors and these symptom scores were examined under the comparison between OAB patients and control patients who had urgency score with less than 2 in OABSS. The OABSS and IPSS/QOL was 7.39 ± 2.69 and 21.2 ± 6.59/4.33 ± 1.33, respectively but those of control patients were 2.00 ± 1.41 and 10.1 ± 9.52/2.14 ± 1.46, respectively (P<0.05). Regarding the correlation of those markers' expressions and symptom scores, in OAB patients, OABSS total significantly correlated with β-3 AR expressions (P=0.0457). IPSS post-voiding significantly correlated with β-3 AR expressions (P=0.0308) but no significant relationship in control patients (P>0.05). In conclusion, this study demonstrated that β-3 AR in our tested 8 markers or receptors was correlated strongly with OAB-related symptoms. These data may help elucidate the pathophysiology of OAB and offer possible strategy for its order-made therapies.

Abstract
OBJECTIVE To assess change in overactive bladder (OAB) symptoms up to 5 years after surgery and to identify associated predictors of change from baseline. METHODS This is a secondary analysis of data from three multicenter urinary incontinence (UI) surgical trials of women with stress-predominant mixed UI assigned to Burch colposuspension, autologous fascial sling, or retropubic or transobturator midurethral slings. The primary outcome was improvement of 70% or greater from baseline in symptoms measured by the Urinary Distress Inventory-Irritative subscale. Surgical groups were compared within respective trials. Generalized linear models were fit using 1-year and up to 5-year data. RESULTS Significant improvements in Urinary Distress Inventory-Irritative scores were reported by each surgical group 1 year after surgery (P<.001). Most women (50-71%) reported improvement in OAB symptoms. Improvements were similar between midurethral sling groups at 1 year (65.5% compared with 70.7%, P=.32; odds ratio [OR] 0.83, 95% confidence interval [CI] 0.57-1.20 for retropubic compared with transobturator sling) and throughout the 5-year follow-up period. More women reported OAB symptom improvement after Burch compared with pubovaginal sling (67.9% compared with 56.6%, P=.01; OR 1.59, 95% CI 1.10-2.31 for Burch compared with sling); this group difference at 1 year persisted throughout the 5-year follow-up. At 1-year, 50.0-64.3% of patients reported 70% greater improvement in UI. This proportion declined to 36.5-54.1% at 5 years (P<.001). Preoperative use of anticholinergics and urodynamic parameters was not predictive of OAB symptom change after surgery. CONCLUSION Most women with stress-predominant mixed UI experienced significant improvement in OAB symptoms after incontinence surgery although this initial improvement diminished over time. Obesity blunted symptom improvement. LEVEL OF EVIDENCE II.

Abstract
OBJECTIVE The objective of this monitoring was to evaluate persistence in the treatment of patients with overactive bladder syndrome (OAB) using mirabegron. DESIGN Prospective clinical study. SETTING 10 gynecological and urological departments in CZE. MATERIALS AND METHODS This is an analysis of a prospective, multicenter monitoring which started in May 2014 and will continue for 1 year. This monitoring included patients 18 years old who have had symptoms of OAB for minimum 3 months. The patient check-up was performed 6 months (±2 weeks) after the first visit. The dosage of mirabegron was 50 mg per day. For the evaluation the treatment efficacy we employed the TS-VAS and PPBC. During the check-up it was ascertained how many patients discontinued the treatment with mirabegron, and reasons for this interruption were established. The statistics were calculated using the software SPSS 20.0. RESULTS A prospective monitoring was performed on 206 patients. Their mean age was 62.8 years (range 23-89); mean body mass index for the whole group of patients was 27.3. At the check-up 6 months post-initiation of treatment it emerged that 55/206 (27%) patiens had discontinued the treatment. The reasons for discontinuation of treatment were: 24/55 (43%) insufficient treatment efficacy, 29/55 (53%) other reasons (the main reasons here were hospitalisation, surgery, gravidity) and 2/55 discontinued therapy because of side effects. The side effects were tachycardia, eye irritation, lower abdominal pain and vasculitis, and they were mild in nature. The termination of the study was 7/28 (25%) in the group of patients without previous treatment before mirabegron. Discontinuation of the treatment in the group of patients with previous anticholinergic treatment was 48/178 (27%). At the evaluation of the efficacy of the treatment during the check-up 6 months after initiation of treatment the mean TS-VAS was 77.5, a decrease of the scale of bothers evaluated by PPBC before treatment from a mean value of 3.56 to a value of 1.77. CONCLUSIONS Our hypothesis, that persistence in treat-ment with mirabegron would be relatively high due to reduced side effects and better cure effect, was confirmed, and this is the reason for higher rates of persistence in the treatment at 6 months check-up (73%).

Abstract
BACKGROUND/AIM To evaluate the effects of pelvic floor muscle training (PFMT) on symptoms of overactive bladder (OAB) as well as uroflowmetry parameters and functional bladder capacity. MATERIALS AND METHODS Fifty-nine female patients with OAB symptoms were included. Patients were assessed by SEAPI-QMM, uroflowmetry, and abdominal ultrasound. A specially designed PFMT program using a Pilates ball was generated for patients. The training period was 1-h sessions twice a week for 6 weeks and aerobic home exercises to be performed at home 4 or 5 times every other day. Following training, subjects were reevaluated for body mass index, SEAPI questionnaire, and uroflowmetry. RESULTS Initial mean SEAPI score, mean maximum and average flow rates, and mean voided volume were 9.8 ± 7.2, 29.8 ± 16.4 mL/s, 16.3 ± 8.7 mL/s, and 211.6 ± 173.5 mL, respectively. After completion of the training program, SEAPI scores improved significantly to 3.4 ± 6.4 (P < 0.05). Maximum and average flow rate results did not show significant changes, whereas voided volume seemed to have improved in conjunction with patients' symptom scores (Pearson correlation coefficient: 0.86). CONCLUSION According to. our results, we think that proper PFMT results in increase of functional bladder capacity as well as improvement in OAB symptoms and can be recommended as first-line therapy or in conjunction with medical therapy in severe cases.

Abstract
UNLABELLED Primary monosymptomatic nocturnal enuresis (PMNE) is the most frequent (85%) type of enuresis in children. It remains a diagnostic and therapeutic challenge to establish its etiology and implement a proper treatment. AIM The aim of the study was to establish the causes of PMNE in children on the basis of own investigations and assess factors having influence over PMNE etiology, which would enable the choice of effective therapy. MATERIALS AND METHODS The study concerned 85 children with PMNE aged from 5 to 15 years. The patients were under the care of Nephrology Outpatient Clinic at Institute of Mather and Child in years 2009-2014. The detailed medical history, physical examination as well as laboratory investigations of blood and urine, and radiological investigations of the urinary tract, were carried out. Statistical analysis was performed using R software. RESULTS In all patients, we have successfully detected the etiology of children of PMNE. The basic, equally frequent (62.3%), PMNE etiopathogenetic factors turned to be: too small bladder capacity resulting from the detrusor hyperactivity, and night polyuria mainly caused by vasopressin deficiency or abnormal eating and hygienic habits, occurring separately or in conjunction with each other. Too small bladder capacity occurred mainly (37.6%, group C) as the only etiological factor of PMNE, and in 24.7% (group A) in a conjunction with nocturnal polyuria due to decreased excretion of vasopressin. Night polyuria was caused by the deficiency of vasopressin in most cases (37.6%) and occurred mainly (24.7%, group D) in a conjunction with small bladder capacity, and rarely alone (12.9%, group B). In 24.7% (group A) it appeared due to eating and hygienic abnormal habits. We have proved statistically significant differences in mean voiding frequency and volume (p<0.0001) between groups A-B and C-D. Mean morning urine specific gravity (p<0.0001) also differed significantly between group C and B (p<0.0001) as well as C and D (p=0.0004). CONCLUSIONS PMNE in all patients was attributed to specific causes outside the circle of psychological disorders what reduced patient stigmatization. PMNE etiology is very complex and diverse. It still remains a challenge and requires and individual diagnostic and therapeutic approach. Voiding frequency above 8 daily with voiding volumes usually below 100 ml suggest etiology connected with small bladder capacity, while morning urine specific gravities below 1.021 g/ml can be connected with vasopressin deficiency or excessive fluid intake before the bedtime. The developed diagnostic approach along with borderline values are hints that can aid physicians in establishing PMNE causes.

Abstract
Overactive bladder (OAB) is a symptom complex which is present in approximately 17% of the European population. It is observed in the presence or absence of incontinence (wet or dry) and is associated with a high degree of psychological stress as well as high costs for the healthcare system. Myogenic, urothelial and neurogenic factors lead to frequently unknown changes of muscular, neural and connective tissue. For the definition, etiology and diagnostics of the disease the previous continuing medical education (CME) article "Diagnosis of overactive bladder (OAB)" should be consulted. In recent years some improvements have been made in OAB-related research, in terms of pathophysiological models and new pharmacological approaches with the development of new therapeutic agents. Besides classical substances, recently approved agents are increasingly being used for the therapy of OAB. Furthermore, non-pharmaceutical approaches and surgical techniques still play an important role in the therapy of OAB.
