Association between Menopausal Symptoms and Overactive Bladder: A Cross-Sectional Questionnaire Survey in China

Role of estradiol and C-reactive protein levels on genitourinary syndrome in menopausal women

Menopause leads to decreased estradiol levels affecting tissue health and causing local inflammation in the genital organs and urinary tract. The rise of blood C-reactive protein (CRP) levels in menopausal women may indicate systemic inflammation associated with estradiol decline. The aim of this study was to determine the relationship between serum estradiol and CRP levels on genitourinary syndrome in menopausal women. A cross-sectional study was conducted among menopausal women who had not experienced menstruation for at least 12 consecutive months at Prof. dr. Chairuddin P. Lubis Hospital, Medan, Indonesia, in 2023. Estradiol and CRP levels were measured using enzyme-linked immunosorbent assay (ELISA) and the presence of genitourinary syndrome was assessed using the Menopause-Specific Quality of Life (MENQOL) questionnaire. The mean levels of estradiol and CRP were compared to menopausal women with and without genitourinary syndrome with the Mann-Whitney test. To assess the correlation between estradiol and CRP levels, and between their levels with the presence of genitourinary symptoms, the Spearman correlation test was used. The genitourinary syndrome was reported in 25% of the total included menopausal women. Our data indicated that the mean estradiol levels were not significantly different between menopausal women with and without genitourinary syndrome (9.13±2.47 pg/mL vs 18.96±31.23 pg/mL, p=0.881). The mean serum CRP level of menopausal women with genitourinary syndrome (9.72±6.30 mg/L) was higher than that of women without the syndrome (2.09±1.26 mg/L) with p<0.001. In addition, serum CRP level, not estradiol, was correlated with the symptom score of genitourinary syndrome. This study highlights that to identify and manage genitourinary syndrome, monitoring of CRP levels is essential in menopausal women.

Isolated bladder training or in combination with other therapies to improve overactive bladder symptoms: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Bladder training (BT), the maintenance of a scheduled voiding regime at gradually adjusted intervals, is a common treatment for overactive bladder (OAB).

OBJECTIVES

To assess the effects of isolated BT and/or in combination with other therapies on OAB symptoms.

METHODS

A systematic review of eight databases was conducted. After screening titles and abstracts, full texts were retrieved. Cochrane RoB 2 and the GRADE approach were used.

RESULTS

Fourteen RCTs were included: they studied isolated BT (n = 11), BT plus drug treatment (DT; n = 5), BT plus intravaginal electrical stimulation (IVES; n = 2), BT plus biofeedback and IVES (n = 1), BT plus pelvic floor muscle training and behavioral therapy (n = 2), BT plus percutaneous tibial nerve stimulation, and BT plus transcutaneous tibial nerve stimulation (n = 1). In a meta-analysis of short-term follow-up data, BT plus IVES resulted in greater improvement in nocturia (mean difference [MD]: 0.89, 95% CI: 0.5, 1.20), urinary incontinence (UI; MD: 1.93, 95% CI: 1.32, 2.55), and quality of life (QoL; MD: 4.87, 95% CI: 2.24, 7.50) than isolated BT, while DT and BT improved UI (MD: 0.58, 95% CI: 0.23, 0.92) more than isolated BT.

CONCLUSION

In the short term, BT plus IVES improves the OAB symptoms of nocturia and UI while improving QoL. The limited number of RCTs and heterogeneity among them provide a low level of evidence, making the effect of BT on OAB inconclusive, which suggests that new RCTs should be performed.

Prevalence of overactive bladder in Chinese women: A systematic review and meta-analysis

BACKGROUND

Overactive bladder (OAB) is a significant public health issue that adversely affects the quality of life of patients and imposes a significant socioeconomic burden, with varying prevalence rates across study populations in Chinese women. A systematic review and meta-analysis were conducted to estimate the prevalence of OAB in Chinese women.

METHODS

Relevant published articles on the prevalence of OAB in Chinese women were searched through July 21, 2022, using PubMed, EMbase, The Cochrane Library, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), WanFang Data, and VIP databases. After the independent screening of articles, data extraction, and quality assessment of included studies by two investigators, a meta-analysis was performed using Stata 16.0 software, and the prevalence was determined using a random-effects model. To identify potential sources of heterogeneity, subgroup analyses were conducted with subgroup categories including age, Body Mass Index (BMI), region, and survey year. Publication bias was assessed by visually examining the funnel plot and Egger's test.

RESULTS

Twenty studies were included in this meta-analysis. The results of the random-effects model indicated that the prevalence of OAB in Chinese women was 14% (95% Confidence Interval: 9%-18%). The prevalence increased significantly in the past decade (from 8% in pre-2006 to 18% in 2016-2021). A prevalence (18%) was observed among women aged 31-40 compared with other age groups. The BMI range of 24-27.9 (18%) was higher than the other groups. Additionally, the prevalence of this BMI range was comparatively higher in North China and Southwest China (21%) than in Central China and East China. In addition, publication bias was observed.

CONCLUSIONS

OAB incidence has increased in Chinese women over the last two decades, affecting more than 20% of women aged 31-40 years and above. With the increasing prevalence of OAB, greater emphasis has been placed on implementing preventative and control measures.

Daidzein is the in vivo active compound of Puerariae Lobatae Radix water extract for muscarinic receptor-3 inhibition against overactive bladder

Background: In the previous study, Puerariae Lobatae Radix (named Gegen in Chinese) water extract attenuated M3 receptor agonist carbachol-induced detrusor contraction after 3-week oral administration in a hypertension-associated OAB (overactive bladder) model. This research aimed to investigate the active ingredients from Gegen water extract against OAB.

Methods: Bioassay-guided fractionation was performed by using preparative HPLC for fast isolation of fractions followed by screening their ex vivo activity through carbachol-induced bladder strip contraction assay. Chemicals in each active fraction were analyzed by HPLC-UV. Urine metabolites were quantified by LC-MS/MS after sub-acute administration. Thermal shift assay with the recombinant human M3 receptor protein was performed, and molecular docking analysis was used for molecular modelling of M3 receptor inhibition.

Results: Bioassay-guided fractionation results for isolating M3 receptor inhibitors indicated that four compounds were identified as active ingredients of Gegen water extract, and their inhibition potency on carbachol-induced detrusor contraction was ranked in descending order according to their inhibition concentrations as follows: genistein > daidzein > biochanin A >> puerarin. Daidzein in urine reached an ex vivo effective concentration to inhibit detrusor contraction, but others did not. Daidzein concentration-dependently increased the melt temperature (Tm) of recombinant human M3 receptor protein with a positive binding (ΔTm = 2.12 °C at 100 μg/ml). Molecular docking analysis showed that daidzein can potently bind to the ligand binding pocket of the M3 receptor via hydrogen bonding.

Conclusion: Puerarin and its derivatives were pro-drugs, and daidzein was their in vivo active form via M3 receptor inhibition for treating OAB.

[Non-neurological overactive bladder and pelvic-perineal pathology in women]

INTRODUCTION

The aim was to synthesize current knowledge on overactive bladder (OAB) and female pelvic-perineal diseases.

METHOD

A systematic literature review based on PubMed, Embase and Google Scholar was conducted in April 2020.

RESULTS

Women with pelvic organ prolapse very often have OAB. Prolapse surgery should be considered if the prolapse is symptomatic and never be indicated in case of overactive bladder symptoms solely. In case of symptomatic prolapse and OAB, pessary and surgical treatments are effective on both pathologies up to 71 % of the cases. OAB may occur in parallel or as part of a menopausal genitourinary syndrome. In the latter case, only local estrogen therapy is effective. OAB may occur alongside stress urinary incontinence (SUI) or be integrated into mixed urinary incontinence. The initial treatment should be based on the most troublesome symptoms. In case of SUI, the outcome of surgical treatment on OAB remains uncertain. De novo, OAB follows prolapse or SUI surgery. It requires investigations to exclude urinary tract infection, bladder outlet obstruction or erosion. The treatment is the same as OAB.

CONCLUSION

The clinician's challenge is to draw a balance between the OAB and a pelvic-perineal pathology in order to adapt the treatment.

Efficacy of Community-based Pelvic Floor Muscle Training to Improve Pelvic Floor Dysfunction in Chinese Perimenopausal Women: A Randomized Controlled Trial

To evaluate the effectiveness of pelvic floor muscle training (PFMT) on perimenopausal women with pelvic floor dysfunction (PFD). A two-group longitudinal experimental design with multiple comparisons. The intervention group (n = 37) received a 3-month intervention combining Kegel and yoga exercise. The control group (n = 37) received Kegel exercise. The combined training alleviated PFD symptoms, improved life quality and increased pelvic floor muscle strength of perimenopausal women. Women with PDF symptoms can integrate PFMT and yoga exercise to promote rehabilitation and improved outcomes. Combined exercise should be taught and practiced under supervision by qualified health professionals.

Associations Between Risk Factors and Overactive Bladder: A Meta-analysis

Age and body mass index are associated with increased risks of overactive bladder, whereas employment status is associated with a decreased risk of overactive bladder.

Objective

The purpose of this study was to investigate the risk factors of overactive bladder (OAB).

Methods

The PubMed, Embase, and Cochrane Library databases were retrieved through May 2016. Odds ratios (OR) or standard mean differences (SMDs) with 95% confidence intervals (CIs) were used to evaluate the associations between risk factors and OAB. Heterogeneity among studies was examined using χ² test based on the Q and I² tests.

Results

A total of 28 articles were analyzed in our study. The results suggested that age and body mass index were significantly higher in OAB patients than in non-OAB controls (SMDs [95% CIs], 0.30 [0.19–0.41] and 0.39 [0.24–0.53]). A significant negative association was found between employment status and OAB (OR [95% CIs], 0.64 [0.46–0.90]). However, sex, educational level, parity, vaginal delivery, race, menopause, marital status, smoking, and alcohol consumption were not significantly different in OAB and non-OAB control patients (ORs [95% CIs], 0.95 [0.59–1.55], 1.04 [0.82, 1.33], 0.98 [0.56–1.70], 1.66 [0.90–3.07], 0.98 [0.75–1.28], 1.84 [0.23–14.70], 0.97 [0.78–1.19], 0.91 [0.77–1.08], and 0.88 [0.71–1.09], respectively). In addition, the number of parities and vaginal deliveries in OAB patients also showed no significant differences compared with non-OAB control patients (SMDs [95% CI], 0.05 [−0.27 to 0.38] and −0.16 [0.40 to 0.09]).

Conclusions

This meta-analysis suggests that age and body mass index are associated with increased risks of OAB, whereas employment status is associated with a decreased risk of OAB. Further prospective studies with large sample sizes are needed to confirm this conclusion.

Behavioral therapy versus drug therapy in individuals with idiopathic overactive bladder: A systematic review and meta-analysis

The aim of this study was to systematically review randomized clinical trials comparing the treatment of individuals with overactive bladder syndrome through the use of behavioral therapy versus drug therapy. A systematic electronic search of MEDLINE via PubMed, Embase, and Cochrane Library was performed, including studies indexed until August 2019. Five randomized clinical trials were included. The studies presented a high risk of bias. There was no significant difference between the evaluated treatments. Thus, behavioral therapy and drug therapy also promote the improvement of the symptoms of overactive bladder syndrome, and the behavioral therapy does not have significant adverse effects reported. Due to the high risk of bias in included studies, data should be interpreted with caution. Future studies with more comprehensive protocols may change the effect estimates of behavioral therapy on overactive bladder syndrome.

Multidisciplinary management of women with pelvic organ prolapse, urinary incontinence and lower urinary tract symptoms.A clinical and psychological overview

Although female sexual dysfunctions are common among women with urogynecological conditions, they have not been thoroughly studied and there are still many questions without an answer. The recent evidence on sexual disorders in women with urogynecological diseases shows a quite wide spectrum of therapeutic approaches, which require the physicians to take into account not only the primary symptoms, but also all the associated factors negatively affected. It has been widely underlined that gynecological diseases are often associated with high stress and have a negative impact on quality of life and psychological well-being of women affected. For this reason, a multidisciplinary approach for the management of these diseases is highly recommended. Also in the case of urogynecological disorders, it is important to take into account psychological outcomes throughout the diagnostic and therapeutic process. In the light of these considerations, the aim of this short review is to evaluate the impact of the main urogynecological diseases and the currently available therapeutic options in order to improve quality of life and sexuality of these patients and to stress the need for a multidisciplinary approach in order to minimize the negative consequences of these diseases for the sexual well-being of women and their partners.

A comparison of sacral neuromodulation vs. transvaginal electrical stimulation for the treatment of refractory overactive bladder: the impact on quality of life, body image, sexual function, and emotional well-being

Overactive bladder syndrome (OAB) is defined by the presence of urinary urgency, with or without urge incontinence, usually accompanied by an increase in urinary frequency and nocturia in the absence of urinary tract infections (UTI) or other diseases. The overall prevalence of OAB symptoms in the female population is reported to be 16.6% and increases with advancing age and menopause. The aetiology of OAB is not fully understood and is likely to affect a heterogeneous population of patients due to changes to their central and peripheral nervous systems. Although OAB is frequently associated with female sexual dysfunction (FSD), its real impact on sexual function in women has been evaluated only in a few studies. The first line of treatment for OAB includes behavioural modification and physical therapy, either as monotherapies or in combination. Many patients who have not had success in managing their symptoms with more conservative therapies may decide to resort to third-line treatments for refractory OAB. These treatments include neuromodulation therapies, particularly transvaginal electrical stimulation (TES) and sacral neuromodulation (SN). The aim of this short commentary is to provide an overview of the effectiveness of these treatments and of their impact on quality of life, body image, sexual function, and emotional well-being.

Risk factors of overactive bladder syndrome and its relation to sexual function in menopausal women

BACKGROUND

Overactive bladder syndrome is a common and annoying complication worldwide that could negatively affect the quality of life of afflicted individuals. We aimed to determine the prevalence and risk factors of overactive bladder syndrome and its relation to sexual function in healthy menopausal women.

METHODS

This cross-sectional study was done on 340 women aged 45-60 years in Tabriz, northwest Iran, during 2015-2016. Data were collected using a demographic data questionnaire, the Overactive Bladder Syndrome Score, and the McCoy Female Sexuality Questionnaire.

RESULTS

Fifty-six (16.5%), 63 (18.5%), and 10 (2.9%) of the participating women had mild, moderate, and severe overactive bladder syndrome, respectively. Predictors of overactive bladder included: night sweats, central prolapse, episiotomy, varicose disease, illiteracy or education at the primary level, systolic blood pressure >140 mmHg and lack of physical activity. We found a significant difference between the women with and without overactive bladder with respect to the total score and sub-domain scores related to sex partner (p = 0.029) and sexual interest (p = 0.049).

CONCLUSIONS

The prevalence of overactive bladder was quite high in this study. Since sexual dysfunction is not an easy topic to talk about and can affect women's quality of life, physicians should consider talking about these issues besides urinary issues to all middle-aged women.

ASSOCIATION OF AGE AT MENOPAUSE WITH POST-MENOPAUSAL SYMPTOMS, MENARCHE AGE AND OTHER REPRODUCTIVE FACTORS AMONG RURAL FEMALES IN SHIMLA, HIMACHAL PRADESH

This study analysed the association between menopause, menarche and number of live births using cross-sectional primary data for 75 post-menopausal rural women from Shimla in the Indian state of Himachal Pradesh. The mean/median ages at menarche of the 75 women were 14.23/14 years, and those at menopause 45.35/45 years. There were no significant differences in these values between women in the age groups 40–55 and 56–65 years. Age at menopause was found to be significantly associated with age at menarche and maternal age at birth of the first and last child, but not with menopausal symptom severity score. The majority of the 75 post-menopausal women (70.7%) had very mild or no menopausal symptoms. Three principal components were identified that explained 72.43% of the underlying variation in menopausal symptoms.
