Abstract
Rationale Overactive bladder (OAB) is a common, distressing condition that worsens with age and impacts quality of life significantly. As a results of its clinical symptoms, patients suffer from serious physical and mental health issues, have a poor quality of life, and participate in a serious economic burden. The key social-psychological factors include living habits, eating habits, and personality characteristics on this disease, even though the pathogenesis of OAB is complex. However, there is few cognitions and research on OAB in the field of psychology. Methods/Search Strategy Between 2000 and 2022, two electronic databases were systematically searched in accordance with Cochrane library guidelines (PubMed/Medline, Web of Science). An analysis of the remaining articles with relevant information was conducted using a data extraction sheet. An itemized flow diagram was adopted and used to report systematic reviews and meta-analysis. A systematic review of studies published from 2000 to 2022 in English language were conducted and included in the review. The intended audience Urological surgeon and psychologists majoring in urinary diseases. Implication As a result of this information, we are able to develop a better understanding of the role of psychological factors in the development of OAB and suggest potential therapeutic directions for OAB patients. This may benefit the recovery of OAB patients.

Mirabegron is better tolerated than solifenacin in Sjogren's syndrome patients with overactive bladder symptoms-A randomized controlled trial. Low Urin Tract Symptoms 2023. [PMID: 37191196 DOI: 10.1111/luts.12481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 03/06/2023] [Accepted: 04/27/2023] [Indexed: 05/17/2023]
Abstract
OBJECTIVES This study investigates the efficacy and adverse events of beta-3 agonists and antimuscarinic agents for managing overactive bladder syndrome in Sjogren syndrome. METHODS Sjogren's syndrome patients with an Overactive Bladder Symptom Score (OABSS) >5 were enrolled and were randomly assigned to mirabegron 50 mg/day or solifenacin 5 mg/day. Patients were evaluated on the recruitment day and reassessed at Week 1, 2, 4, and 12. The study's primary endpoint was to have a significant change in OABSS at Week 12. The secondary endpoint was the adverse event and crossover rate. RESULTS A total of 41 patients were included in the final analysis, with 24 in the mirabegron group and 17 in the solifenacin group. The study's primary outcome was a change of the OABSS at Week 12. We found that both mirabegron and solifenacin significantly reduce patients' OABSS after 12 weeks of treatment. The evolution of the OABSS was -3.08 for mirabegron and -3.71 for solifenacin (p = .56). Six out of 17 patients from the solifenacin group crossed over to the mirabegron arm due to severe dry mouth or constipation, while none from the mirabegron arm crossed over to the solifenacin group. Sjogren's syndrome-related pain was also improved in the mirabegron group (4.96-1.67, p = .008) compared to the solifenacin group (4.39-3.4, p = .49). CONCLUSIONS Our study showed that mirabegron is equally effective as solifenacin in treating Sjogren's syndrome patients with overactive bladder. Mirabegron is superior to solifenacin in terms of treatment-related adverse events.

Abstract
OBJECTIVE In this 3-year longitudinal cohort study, we aimed to evaluate the evolution of overactive bladder in female community residents aged 40 years and above in central Taiwan and identify its risk factors. MATERIALS AND METHODS Female community residents aged 40 years and above were invited to participate in this study and fill out a yearly Overactive Bladder Symptom Score (OABSS) questionnaire over a 3-year period. A woman was defined to have OAB if the total OABSS was ≧4 and urgency score was ≧2. At the end of the third year, the incidence, remission, persistence, and relapse of OAB in these community residents were calculated. A novel statistical analysis technique, machine learning with data mining, was applied to examine its use in this field. Five machine learning models were used to predict the risk factors associated with persistent OAB and the results were compared with the conventional logistic regression model. RESULTS In total, 1469 female residents were included in the first year and 1290 (87.8%) women completed the questionnaires for all 3 years. The prevalence of OAB was 20.2% (n = 260). The second- and third-year incidence rates of OAB were 13.5% and 7.1%. The remission rates were 39.6% and 44.3%. Twenty-two percent of the women reported relapse of OAB in the third year. The two-year OAB persistence rate was 43.8%. For the prediction of risk factors for persistent OAB, the multivariable logistic regression model had better predictive accuracy (AUC = 0.664) than the five machine learning models. Age ≧ 60 was associated with persistent OAB (OR 2.8; 95% CI: 1.34-5.89, P = 0.002). CONCLUSION The yearly incidence, remission, and persistence rates of OAB were high in female community residents aged 40 years and above in central Taiwan. Older women had a higher risk of persistent OAB symptoms in this 3-year longitudinal cohort study.

Abstract
BACKGROUND Pregnancy and childbirth are frequently associated with overactive bladder syndrome (OAB). However, the role of parous effects in OAB among nulliparous (NP) women remains controversial. METHODS This study investigated abnormal voiding patterns and detrusor overactivity (DO) among NP women with OAB in comparison with parous women. From August 2011 to December 2018, 906 patients met the inclusion criteria for participation and were divided into three groups: 221 patients in the NP group, 571 patients in the normal spontaneous delivery (NSD) group, and 114 patients in the cesarean section (CS) group. Urodynamic study examinations were performed, and the presence of DO, abnormal voiding patterns, and maximum urethral closure pressure (MUCP) was recorded. Data were analyzed using analysis of variance, χ2 tests, and independent t tests. RESULTS Compared with parous women in the NSD and CS groups, patients in the NP group had a significantly higher prevalence of abnormal voiding patterns, DO, and MUCP. Furthermore, abnormal voiding patterns were significantly associated with DO and MUCP, respectively, especially in the NP group. CONCLUSION We hypothesized that hypertonicity or poor relaxation of the pelvic muscle in NP women may cause functional BOO, which is related to their OAB.

Abstract
AIMS Overactive bladder (OAB) syndrome has been associated with core muscles weakness, which is important in aetiology of low back pain (LBP) and affects general well-being. This study aimed to compare the lumbopelvic stability, LBP and well-being of women with OAB to asymptomatic controls and to determine the cut-off points. METHODS Women with (OAB group, n = 36) and without OAB syndrome (control group, n = 36) were included. The lumbopelvic stability with the Sahrmann and McGill trunk muscle endurance tests, LBP intensity with the Visual Analogue Scale were assessed. As for general well-being, sleep quality with the Pittsburgh Sleep Quality Index (PSQI), fatigue severity with the Fatigue Severity Index (FSI), anxiety and depression levels with the Hospital Anxiety Depression Scale (HADS-A, HADS-D) were evaluated. RESULTS In the OAB group compared to the control group, the lumbopelvic stability scores were lower (p < 0.001) while LBP prevalence (p < 0.001), pain intensity (p = 0.020), and PSQI, FSI, HADS-A, and HADS-D scores (p < 0.001) were higher. The cut-off points for trunk extension, flexion, right and left lateral flexion endurance tests and Sahrmann test were ≤9.42 sec, ≤8.62 sec, ≤19.26 sec, ≤5.16 sec, and ≤2 level, respectively. The cut-off points for PSQI, FSI, HADS-D, HADS-A were >5, >5.22, >6 and >6 scores, respectively. CONCLUSIONS Women with OAB syndrome had lower lumbopelvic stability, higher LBP prevalence and intensity, lower sleep quality, and more fatigue, anxiety, and depression levels compared to asymptomatic women. The cut-off values were detected between the occurrence of OAB and lumbopelvic stability and general well-being parameters.

BIOLOGY 2021; 10:biology10060540. [PMID: 34208659 PMCID: PMC8235660 DOI: 10.3390/biology10060540] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 06/08/2021] [Accepted: 06/12/2021] [Indexed: 01/19/2023]
Abstract
Simple Summary Overactive bladder (OAB) is a common urologic condition with urinary frequency, urinary urgency, nocturia, and urgency incontinence, which can get in the way of a patient’s social life, exercise, work, and sleep. Exploring a promising option for OAB patients is very important, especially one with less side effects or invasive alternations. This study uses low intensity extracorporeal shock wave therapy (LiESWT) to investigate the therapeutic effect and duration on OAB symptoms. Abstract Background: The present study attempted to investigate the therapeutic effect and duration of low intensity extracorporeal shock wave therapy (LiESWT) on overactive bladder (OAB) symptoms, including social activity and the quality of life (QoL). Methods: In this prospective, randomized, single-blinded clinical trial, 65 participants with OAB symptom were randomly divided into receive LiESWT (0.25 mJ/mm2, 3000 pulses, 3 pulses/second) once a week for 8 weeks, or an identical sham LiESWT treatment without the energy transmission. We analyzed the difference in overactive bladder symptom score (OABSS) and 3-day urinary diary as the primary end. The secondary endpoint consisted of the change in uroflowmetry, post-voided residual (PVR) urine, and validated standardized questionnaires at the baseline (W0), 4-week (W4) and 8-week (W8) of LiESWT, and 1-month (F1), 3-month (F3) and 6-month (F6) follow-up after LiESWT. Results: 8-week LiESWT could significantly decrease urinary frequency, nocturia, urgency, and PVR volume, but meaningfully increase functional bladder capacity, average voided volume and maximal flow rate (Qmax) as compared with the W0 in the LiESWT group. In addition, the scores calculated from questionnaires were meaningfully reduced at W4, W8, F1, F3, and F6 in the LiESWT group. Conclusions: Our results revealed that the therapeutic efficacy of LiESWT could improve voided volume and ameliorate OAB symptoms, such as urgency, frequency, nocturia, and urinary incontinence, and lasted up to 6 month of follow-up. Moreover, LiESWT treatment brought statistically significant and clinically meaningful improvements in social activity and QoL of patients. These findings suggested that LiESWT could serve as an alternative non-invasive therapy for OAB patients.

Abstract
OBJECTIVES To evaluate the short-term evolution and risk factors of overactive bladder (OAB) in community-dwelling male residents aged 40 years and above in central Taiwan. METHODS This was a 3-year longitudinal cohort study. From January 2012 to December 2012, community residents aged 40 years and above, living in central Taiwan, were invited to participate in this study. A yearly Overactive Bladder Symptom Score (OABSS) questionnaire was used to assess the prevalence, incidence, remission, persistence, and relapse of OAB for three consecutive years. OAB was defined as total OABSS ≧4 and urgency score ≧2. RESULTS Nine hundred forty-one male residents aged ≧40 years were recruited. The prevalence of OAB was 15%. The male residents with OAB were older, had a history of urological surgery, were unemployed, had lower educational levels, and lower yearly incomes compared with male residents without OAB. The prevalence increased with age when stratified into different age cohorts (40-49, 7%; 50-59, 12.7%; 60-69, 18.2%; ≧70, 32%; P < .001). Age ≧60 (odds ratio [OR] 2.58; 95% CI, 1.62-4.11) and history of urological surgery (OR 2.85; 95% CI, 1.29-6.30) were the major risk factors after multivariable logistic regression analysis. Eight hundred participants completed all the 3 years' questionnaires. The second- and third-year incidence rates of OAB were 10% (69/691) and 6.2% (42/674), respectively. The remission rates were 47.7% (52/109) and 46% (58/126), respectively. The two-year OAB persistence rate was 30.3% (33/109). CONCLUSIONS The prevalence and yearly incidence of OAB are high in community-dwelling male residents aged ≧40 years in central Taiwan. Age is an important risk factor.

Abstract
BACKGROUND/PURPOSE To investigate the effects of simulated childbirth on the gene expression of parasympathetic muscarinic, purinergic (P2X), and neurokinin receptors of lower urinary tract in rats. METHODS In all, twenty-four primiparous pregnant Sprague-Dawley female rats were equally divided into three groups: (1). Control group; 8 rats, (2) intra-vaginal balloon dilation for 2 h group; 8 rats, (3) and for 4 h group; 8 rats. After balloon dilatation for 4 months, all rats were sacrificed. We analyzed the gene expression of parasympathetic muscarinic, purinergic (P2X), and neurokinin receptors by real-time quantitative PCR (q-PCR). We quantified pro-inflammatory cytokines of TNF-α and IL-6 by Enzyme-linked immunosorbent assays (ELISA). The urodynamic parameters and micturition frequency by cystometry (CMG) were recorded. RESULTS Our results showed that the balloon dilation significantly increased micturition frequency and modified peak micturition pressure compare to those in the control groups. Balloon dilation significantly decreased voiding interval and bladder volume compared to those in the control groups. Gene expressions of M3 muscarinic, P2X3 purinergic receptors, and significantly increased following balloon dilation for 2 hours and 4 hours than those in the control group. In addition, we found that NK1R and NK3R receptors were significantly decreased after balloon dilation compare to control group. The marked increase of TNF-α and IL-6 were also seen in the 2 balloon groups. CONCLUSION The results of our study suggested that birth trauma may impair the function of urinary tract, this being partly related to the changes in the gene expression of the neurotransmitter receptors of the lower urinary tract.

Abstract
OBJECTIVE The present study investigated the inhibitory effects of a novel minimally invasive implanted tibial nerve stimulation device on non-nociceptive bladder reflexes in cats. MATERIALS AND METHODS A wireless minimally invasive implanted nerve stimulator was implanted adjacent to the left tibial nerve in seven cats. Multiple cystometrograms (CMGs) were obtained to determine the inhibitory effects of tibial nerve stimulation (TNS) at different frequencies and intensities on the micturition reflex by infusing normal saline (NS). RESULTS TNS at 6 Hz did not significantly change the bladder capacity (BC) compared to the control level at the intensity threshold (T), while TNS significantly (P < 0.05) increased the BC to 158.89 ± 20.57% of the control level at 2 T. When stimulated at 15 Hz, TNS did not significantly (P > 0.05) change the BCs at 1 T and 2 T. CONCLUSIONS The minimally invasive implanted TNS device was shown to be effective in inhibiting the micturition reflex under physiologic conditions. Further studies are warranted to determine the inhibitory effects of TNS on nociceptive bladder reflexes.

Low-Intensity Extracorporeal Shock Wave Therapy Ameliorates the Overactive Bladder: A Prospective Pilot Study. BIOMED RESEARCH INTERNATIONAL 2020; 2020:9175676. [PMID: 32724817 PMCID: PMC7364200 DOI: 10.1155/2020/9175676] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 05/25/2020] [Accepted: 05/30/2020] [Indexed: 12/20/2022]
Abstract
Objective In the present clinical trial, we evaluated the therapeutic effects of low-intensity extracorporeal shockwave therapy (LiESWT) on overactive bladder (OAB). Methods Female subjects with ages of 20-75 years and who have been clinically diagnosed with OAB were included in the study. The LiESWT (DUOLITH SD1 T-TOP, AG) applicator was placed on the suprapubic skin area and applied with an intensity of 0.25 mJ/mm2, 3000 pulses, and 3 pulses/second. To assess the therapeutic efficacy, all subjects were required to complete the validated OAB symptoms and life bothersome questionnaires, 3-day urinary diary, uroflowmetry, and post-voided residual urine (PVR) measurement at 4 weeks of LiESWT (W4), 8 weeks of LiESWT (W8), 1-month follow-up (F1), and 3-month follow-up (F3) after LiESWT. Result 82 subjects with the mean age of 56.5 ± 1.2 years were enrolled. The questionnaire scores were significantly improved at W4, W8, F1, and F3 as compared to baseline data (W0). At W8, the mean values of functional bladder capacity were meaningfully increased. According to the 3-day urinary diary, daytime frequency, urgency, and nocturia were significantly decreased. The uroflowmetry results showed that the mean voided urine volume and the maximal flow rate (Qmax) were noticeably increased. PVR volume was also significantly decreased. Conclusions The data demonstrated that 8-week LiESWT ameliorated the OAB symptoms, promoted the uroflow parameters, and improved the quality of life (QoL) in OAB patients, suggesting that LiESWT might serve as an alternative noninvasive therapy for OAB.

Abstract
OBJECTIVES To assess prevalence of urinary incontinence (UI), including urgency UI (UUI), stress UI (SUI) and mixed UI (MUI) in individuals aged ≥40 years in China, Taiwan and South Korea. METHOD This was a post hoc analysis of a cross-sectional, questionnaire-based internet survey. Participants were asked questions relating to urinary symptoms, health-related quality of life (HRQoL) and mental health (using the HRQoL 12-item short form health survey mental health and physical domains, and the Hospital Anxiety and Depression Scale), visits to healthcare professionals (HCPs) for any reason or for urinary symptoms, treatments for urinary symptoms and treatment satisfaction. RESULTS Of 8284 survey participants, 1818 (22%) reported any UI (men 17.3%, women 26.4%). MUI was the most prevalent (overall 9.7%, men 6.8%, women 12.6%) followed by SUI (overall 7.9%, men 5.1%, women 10.7%) and UUI (overall 4.3%, men 5.5%, women 3.2%). HRQoL, anxiety and depression scores were poor in all participants with UI; MUI was associated with the worst scores. Of the participants with UI, 46.9% visited HCPs for urinary symptoms (highest proportion [62.7%] among participants with MUI). Approximately 80% of participants with UI followed treatment, with prescribed medicine being the most common form (38.1%). Over half of participants (59.6%) were somewhat, very, or extremely satisfied with their treatment. MUI was associated with least satisfaction. CONCLUSION UI was associated with substantial problems, including an adverse impact on HRQoL. Medication failed to satisfy many individuals with UI. Efforts to educate the public and physicians about the impact of UI could improve diagnosis and treatment rates.

The probability of re-treatment after discontinuation of a 3-month versus a 6-month course of solifenacin for female overactive bladder: A prospective randomized controlled study. Maturitas 2019; 126:11-17. [PMID: 31239111 DOI: 10.1016/j.maturitas.2019.04.216] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2019] [Revised: 03/17/2019] [Accepted: 04/14/2019] [Indexed: 11/30/2022]
Abstract
OBJECTIVES The aim of this study is to compare the re-treatment probabilities after a 3-month versus a 6-month course of antimuscarinic treatment for women with overactive bladder syndrome (OAB). STUDY DESIGN A prospective randomized controlled study. MAIN OUTCOME MEASURES Between-group differences in the probability of re-treatment for OAB between the 3-month and 6-month groups. METHODS Women with OAB were randomly allocated to receive solifenacin (5 mg per day) for a treatment interval of either 3 or 6 months. RESULTS Ninety-one patients were treated in each group. The probability of re-treatment did not differ between the 3-month and 6-month groups (P = 0.11). Parity (hazard ratio = 1.81, P = 0.001), number of incontinence episodes (hazard ratio = 1.09, P = 0.008) and suboptimal response (hazard ratio = 3.56, P = 0.006) were independent predictors of re-treatment of OAB. Physical limitation, as indicated on the King's Health Questionnaire, was the only independent factor predicting completion of the scheduled treatment period (odds ratio = 1.01, P = 0.008). CONCLUSIONS Prolonged antimuscarinic treatment does not decrease the need for re-treatment of OAB. Nonetheless, female patients with increased parity, more severe incontinence and a suboptimal response to antimuscarinic treatment are more likely to seek re-treatment of OAB due to recurrence of symptoms. In addition, patients with more serious physical limitation related to OAB are more likely to complete the scheduled treatment period. These findings could serve as a guide in clinical consultations regarding antimuscarinic treatment and if taken into consideration in future studies could lower the dropout rate.

Urodynamic and Bladder Diary Factors Predict Overactive Bladder-wet in Women: A Comparison With Overactive Bladder-dry. Int Neurourol J 2019; 23:69-74. [PMID: 30943696 PMCID: PMC6449656 DOI: 10.5213/inj.1836212.106] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2018] [Accepted: 02/19/2019] [Indexed: 01/03/2023] Open
Abstract
Purpose To identify factors predicting the presence of overactive bladder syndrome (OAB)-wet, compared with OAB-dry. Methods Between September 2007 and September 2013, the medical records of 623 women with OAB who completed a 3-day bladder diary and underwent urodynamic studies in a medical center were retrospectively reviewed. OAB-wet was diagnosed in patients who complained of at least one episode of urgency incontinence in the previous month; otherwise, OAB-dry was diagnosed. Multivariable logistic regression analysis was used to predict the presence of OAB-wet. Results Age (odds ratio [OR], 1.05; P<0.001), maximal flow rate (Qmax) (OR,1.06; P<0.001), voided volume (OR, 0.996; P=0.001), detrusor pressure at maximal flow rate (PdetQmax) (OR, 1.02; P=0.003), urgency episodes (OR, 1.04; P<0.001) and urodynamic stress incontinence (OR,1.78; P=0.01) were independent predictors for the presence of OAB-wet vs. OAB-dry. If we use bladder contractility index as a variable for multivariable logistic regression analysis, bladder contractility index (OR, 1.012; P<0.001) become an independent predictor for OAB-wet. Conclusions A smaller bladder capacity and more frequent urgency episodes were predictors of OAB-wet, and the above findings indicate that OAB-wet and OAB-dry might be a continuum of OAB. Old age, high Qmax, high PdetQmax and urodynamic stress incontinence were also predictors for OAB-wet, and the above results reveal that OAB-wet and OAB-dry have partially different clinical and urodynamic features. Further studies might be performed to elucidate whether different treatment strategies between OAB-dry and OAB-wet can improve treatment efficacy.

Abstract
Objective The aim of the present study was to determine the prevalence of overactive bladder (OAB) in individuals aged ≥40 years in China, Taiwan, and South Korea. Methods The present cross‐sectional population‐representative Internet‐based study investigated OAB symptoms in men and women aged ≥40 years using the overactive bladder symptom score. Additional instruments included the International Index of Erectile Function (men only) and the Sexual Quality of Life – Female (women only) questionnaires, as well as Patient Perception of Bladder Condition (PPBC). Results In all, 8284 individuals participated in the study. The prevalence of OAB was 20.8% overall (women 22.1%, men 19.5%) and increased significantly with age, from 10.8% in those aged 40–44 years to 27.9% in those aged >60 years (P = .001). The presence of comorbid conditions (e.g. neurological disease, diabetes) was associated with a significantly increased prevalence of OAB. Increasing symptom severity was associated with significantly worsening patient perception of bladder condition responses. Just under half (48%) of those with no OAB had no lower urinary tract symptoms (LUTS), whereas 88% of those with severe symptoms had all 3 LUTS (International Continence Society definition) symptom categories (voiding, post‐micturition, and storage symptoms). Of those without OAB, 10% reported visiting healthcare professionals for urinary symptoms, compared with 64% of those with severe OAB symptoms (P = .001). Increased symptom severity was significantly associated with lower sexual quality of life in both men and women. Conclusions OAB symptoms were found to affect 1 in 5 individuals aged ≥40 years in China, Taiwan, and South Korea, becoming more common with increasing age. The results suggest that many more individuals with OAB could benefit by consulting healthcare professionals.

Abstract
OBJECTIVE The aim of the study was to investigate predictive factors of the need for persistent antimuscarinic therapy or re-treatment (PR) after discontinuation of antimuscarinic therapy for women with overactive bladder syndrome (OAB). METHODS All consecutive OAB women were enrolled in a prospective cohort study, and treated with solifenacin for 12 weeks in a University Hospital. Factors affecting PR were analyzed by Cox regression analysis. RESULTS A total of 122 women were enrolled, and 107 women underwent 12-week solifenacin treatment. The dropout rate was 12.3%. The median follow-up period was 20.4 weeks (25-75 interquartile range: 16-102.3 wk). Twenty-seven (25%) women had PR. The median PR-free interval was 125.4 weeks (95% CI = 58.4 to - wk). Nocturia episodes (hazard ratio = 1.54), a suboptimal response (hazard ratio = 2.53), and the strong-desire volume (hazard ratio = 0.992) were independent predictors of PR by Cox backward stepwise regression analysis. The areas under the receiver-operating characteristic curves for nocturia episodes, a suboptimal response, and the strong-desire volume to predict PR were only 0.65, 0.63, and 0.59, respectively. In addition, normalized urinary nerve growth factor level was not significant (hazard ratio = 1.005, P = 0.68) for predicting PR. Furthermore, normalized urodynamic findings did not correlate with PR, a suboptimal response, or changes of Overactive Bladder Symptom Score and urinary nerve growth factor level. CONCLUSIONS Frequent nocturia episodes, a suboptimal response, and small bladder capacity may predict PR after solifenacin treatment. These findings may serve as an initial guide in consultation regarding the treatment of OAB.

Abstract
OBJECTIVE Estrogen is considered to be a unique hormone in females that has an impact on voiding function. Animal models and clinical epidemiologic studies showed high correlation between estrogen deficiency and female overactive bladder (OAB) symptoms. We designed a population-based cohort study from a national health database to assess the association of estrogen deprivation therapy and female OAB. MATERIALS AND METHODS This study examined the records of 16,128 patients ranging in age from 18 to 40 that were included in the Taiwan National Health Insurance Research Database (NHIRD) in the years between 2001 and 2010. Of these, 1008 had breast cancer with hormone therapy only and the other 15,120 controls did not have breast cancer or hormone therapy. All patients with neurologic diseases and those with pre-existing OAB identified by information in the NHIRD database were excluded. OAB was defined by medications prescribed for at least 1 month. Risk of new onset OAB in the breast cancer and nonbreast cancer groups was estimated. Fourteen patients (1.4%) experienced OAB in the breast cancer group. Overall, breast cancer with estrogen deprivation therapy increased the risk of OAB by 14.37-fold (adjusted hazard ratio, 95% confidence interval 7.06-29.27). Subgroup analysis showed that in the older age breast cancer group (36-40), a lower Charlson comorbidity index (CCI) score and antidepressant medication use for at least 30 days had an impact on the increase of OAB risk. After adjustment of variables, the higher CCI and the use of antipsychotic drugs increased risk of OAB 3.45-fold and 7.45-fold, respectively. The Kaplan-Meier analysis of OAB-free survival in the breast cancer group showed a significant time-dependent increase in incidence of OAB. CONCLUSION Estrogen deprivation in young patients with breast cancer increased the risk of OAB. The OAB development rate was steady and fast in the beginning 3 years after estrogen deprivation. This result indicates a role of estrogen in the modulation of female voiding function.

Abstract
This review assessed the epidemiology of voiding dysfunctions in South Korea. Comprehensive understanding of this epidemiology is crucial because the senior population and the social burden are increasing because of voiding dysfunctions is growing. We searched the medical records using several terms related to voiding dysfunction: benign prostatic hyperplasia, urinary incontinence, lower urinary tract symptoms, overactive bladder, and nocturia. We then estimated the prevalence of voiding dysfunctions in South Korea; our data were comparable with those from other countries, with slight differences. The ranges of incidences varied widely between studies, mostly because investigators defined disorders differently. Voiding dysfunction greatly affects healthcare costs and individual quality of life; therefore, more proper and valuable epidemiologic data are needed. In addition, efforts to unify the definitions of various voiding dysfunctions and progress in investigational methodologies using multimedia are warranted.

Abstract
A comprehensive and correct understanding of epidemiologic finding about lower urinary tract symptoms (LUTS) is important for several reasons. First, LUTS are highly prevalent in both genders all around the world and are expected to be a major concern to physicians in the near future because of the rapid rise in the elderly population. Second, it is crucial to observe trends in prevalence when national health care policy is established. By using a Medline search with various terms related to LUTS and prevalence, a review of epidemiologic studies was undertaken with an emphasis on the status in Korea. Despite the suggestions made by the International Continence Society, the lack of uniform definitions and the lack of a unified threshold of symptoms are the biggest obstacles in epidemiologic study with regard to LUTS. Most Korean epidemiologic studies on LUTS have been reported since 2000 and reveal that the prevalences of specific clinical conditions, such as LUTS, benign prostatic hyperplasia, overactive bladder, and detrusor underactivity, are in line with prevalences in Western counties. However, the prevalence of nocturia is somewhat different from that in Western countries. Many epidemiologic studies of LUTS have provided us with valuable information and a better understanding of the clinical conditions. Given that the impact of these clinical conditions on quality of life and health care cost will be emphasized more in the near future, more studies on optimal management approaches to LUTS are needed on the basis of this knowledge.
