Effect of Dietary Choline Consumption on the Development of Urinary Urgency Incontinence in a Longitudinal Cohort of Women

INTRODUCTION AND HYPOTHESIS

The objective of this study was to determine whether differences in the cumulative dietary intake of choline, is associated with the risk of developing urge urinary incontinence (UUI).

METHODS

This was an analysis within the Nurses' Health Study (NHS) I and II. The main exposure was the cumulative daily intake for each choline-containing compound obtained from a detailed daily food frequency questionnaire. The primary outcome was UUI, defined as urine loss with a sudden feeling of bladder fullness or when a toilet is inaccessible, occurring >1/month. Cox proportional hazards regression models were used to calculate multivariate-adjusted relative risks and 95% confidence intervals (CIs) for the association between total choline and choline derivatives and risk of UUI. Fixed effects meta-analyses of results from NHSI and NHSII were performed for postmenopausal women only to obtain a pooled estimate of the impact of choline consumption on UUI.

RESULTS

There were 33,273 participants in NHSI and 38,732 in NHSII who met all the criteria for inclusion in the analysis. The incidence of UUI was 9.41% (n=3,139) in NHSI and 4.25% (n=1,646) in NHSII. After adjusting for confounders choline was not found to be associated with UUI in postmenopausal women. However, in premenopausal women, relative to the lowest quartile, the highest quartile of consumption of total choline (aRR = 0.79, 95% CI: 0.64-0.99), free choline (aRR = 0.74, 95% CI: 0.58-0.94), and phosphocholine (aRR = 0.77, 95% CI: 0.61-0.96) were associated with a reduced risk of UUI.

CONCLUSIONS

Increased dietary choline consumption was associated with a reduced risk of UUI among premenopausal women.

[Prevalence of urinary incontinence in middle-aged and elderly adults in 10 areas in China]

Objective: To describe the population and area distribution differences in the prevalence of urinary incontinence in middle-aged and elderly adults in 10 areas in China. Methods: A total of 24 913 participants aged 45-95 years who completed the third resurvey of China Kadoorie Biobank during 2020-2021 were included. The prevalence of urinary incontinence was assessed by an interviewer-administered questionnaire, and urinary incontinence was classified as only stress urinary incontinence, only urgency urinary incontinence and mixed urinary incontinence. The prevalence of urinary incontinence and its subtypes were reported by sex, age and area, and the severity of urinary incontinence and treatment were described. Results: The average age of the participants was (65.4±9.1) years. According to the seventh national census data in 2020, the age-standardized prevalence rates of urinary incontinence was 25.4% in women and 7.0% in men. The age-standardized prevalence rates of only stress, only urgency and mixed incontinence were 1.7%, 4.2% and 1.2% in men and 13.5%, 5.8% and 6.1% in women, respectively. The prevalence rates of urinary incontinence and all subtypes in men and the prevalence of urinary incontinence and all subtypes except only stress urinary incontinence in women all increased with age (P<0.001). After adjusting for age, the prevalence of urinary incontinence in both men and women were higher in rural area than in urban area (P<0.001). The treatment rates in men and women with urinary incontinence were 15.4% and 8.5%, respectively. Conclusions: The prevalence of urinary incontinence was high in middle-aged and elderly adults in China, and the prevalence rate was higher in women than in men, but the treatment rate of urinary incontinence was low.

Association between weight-adjusted-waist index and urge urinary incontinence: a cross-sectional study from NHANES 2013 to 2018

This study aimed to investigate the association between urge urinary incontinence (UUI) and weight-adjusted waist circumference index (WWI), a newly developed measure of obesity. Data from the 2013-2018 National Health and Nutrition Examination Survey (NHANES) were included in the present cross-sectional study. Urge urinary incontinence was identified by self-reported urine leakage before reaching the toilet. Weighted multivariate logistic regression and generalized additive models were used to investigate the connection between WWI and UUI and its nonlinearity. The nonlinear relationship was explored using smoothed curve fitting. Additionally, further analyses were performed on subgroups and interaction tests were conducted. In the study, a total of 14,118 individuals were enrolled, with a UUI prevalence rate of 21.18%. Overall UUI was more prevalent with elevated WWI (OR 1.20, 95% CI 1.13-12.8, P < 0.0001), which similar results were observed in weekly (OR 1.32, 95% CI 1.18-1.48, P < 0.0001) and daily (OR 1.27, 95% CI 1.06-1.53, P = 0.0091) UUI. And this connection remained steady among all subgroups (P > 0.05 for all interactions). Smoothed curve fitting showed no nonlinear relationship between WWI and UUI. In addition, a stronger correlation was found between WWI and UUI risk than other obesity indicators such as waist circumference (WC) and body mass index (BMI). Among US adults, weight-adjusted waist circumference index values are positively associated with elevated odds of UUI and show stronger associations than WC and BMI. Further studies are required to elucidate the causal relationship between WWI and UUI.

Association Between Sleep Duration and Urinary Incontinence in Female Adults: A Cross-sectional Study in National Health and Nutrition Examination Survey 2007-2018

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.

Comprehensive study of anxiety and depression in females with urinary incontinence

BACKGROUND

Anxiety and depression are commonly seen with urinary incontinence (UI) and its association is strongest for urgency and mixed UI. It affects the quality of life and functional status.

AIMS

To assess the prevalence and severity of anxiety and depression in SUI (Stress urinary incontinence) and UUI/MUI (Urge or mixed urinary incontinence), to assess the severity of SUI and UUI/MUI and its association with anxiety and depression and to identify various factors associated with anxiety and depression.

MATERIALS AND METHODS

An observational study using various tools as history regarding urinary incontinence, history of other prior events which can lead to anxiety or depression, age, educational level, BMI (Body mass index), HADS scale (Hospital anxiety and depression scale) for anxiety and depression and ICIQ-UI-SF score (International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form).

RESULTS

The Prevalence of anxiety and depression in UUI/MUI was higher. More women were overweight (BMI > 25) in the UUI/MUI group. Higher prevalence of anxiety and depression in the very severe urinary incontinence group. No association of the level of education with anxiety and depression in women with urinary incontinence.

CONCLUSION

Anxiety and depression are more in UUI/MUI patients compared to SUI. In obese ladies, UUI is more prevalent compared to SUI. Anxiety and depression are more with increasing severity of incontinence. Anxiety and depression have no association with the educational status of the patients.

Prevalence and Quality of Life among Overweight and Obese Women with Different Severity and Types of Urinary Incontinence

OBJECTIVE

Urinary incontinence (UI) is an involuntary leakage of urine and affects the social, physical, and psychological aspects of many individuals worldwide. The purpose of our study was to examine the prevalence, quality of life (QoL), severity, and different types of UI in overweight and obese women.

METHODS

We conducted a cross-sectional study of 1,351 consecutive patients, who were recruited between June 2021 and May 2022.

RESULTS

The mean age of the patients was 39.7 ± 14.2 years with less than a half in the 19-35-year age group (46.9%); 65% of the subjects were overweight or obese. The overall prevalence of UI was 61.2%. Overweight and obesity accounted to 70.2% of patients with mild to very severe UI. The risk estimates to have UI were 1.84 in overweight and 5.4 in obese group. The risk estimate for severe and very severe UI was 2.33 in overweight and 10.34 in obese group. When considering all subtypes, 67.9% of women with overweight and obesity had any of the subtypes, urge UI, stress UI, and mixed UI. Overweight and obesity were significantly associated with poor QoL in women with UI (p < 0.0001). Among 36.1% of all patients with poor QoL, 79.9% were overweight and obese.

CONCLUSIONS

Overweight and obesity are important risk factors of UI affecting daily activity and QOL considerably. As the number of people with obesity is increasing, the prevalence of UI with increased severity is likely to increase in young to mid-aged women. Weight loss should be considered as first-line treatment for this patient population.

Food Insecurity Is Associated With Urge Urinary Incontinence: An Analysis of the 2005-2010 National Health and Nutrition Examination Survey

PURPOSE

Urge urinary incontinence is the involuntary leakage of urine associated with a sudden compelling urge to void. A previous study found an association between urge urinary incontinence and household income, indicating that social determinants of health may influence urge urinary incontinence. Food insecurity is a relevant social determinant of health, as a diet with bladder irritants may worsen urge urinary incontinence symptoms. This study aimed to investigate the association between urge urinary incontinence and food insecurity.

MATERIALS AND METHODS

We collected data from the 2005-2010 cycles of the National Health and Nutrition Examination Survey, a nationally representative health survey administered by the Centers for Disease Control and Prevention. The association between urge urinary incontinence and food insecurity was analyzed using survey-weighed logistic regression with adjustments for demographic, socioeconomic status, behavioral, and medical comorbidities covariates.

RESULTS

We included 14,847 participants with mean age 50.4±17.9 years; 22.4% of participants reported at least 1 episode of urge urinary incontinence. We found that participants who reported food insecurity had 55% greater odds of experiencing urge urinary incontinence compared to those who have not (OR=1.55, 95% CI=1.33-1.82, P < .001). When comparing diets, food-insecure participants reported significantly less intake of bladder irritants (caffeine and alcohol) compared to food-secure participants. When the sample was stratified by food insecurity status (yes vs no), consumption of caffeine did not differ by urge urinary incontinence status and consumption of alcohol was lower among participants with vs without urge urinary incontinence.

CONCLUSIONS

Adults reporting food insecurity in the past year are significantly more likely to experience urge urinary incontinence than those who did not. Consumption of bladder irritants including caffeine and alcohol was significantly less in food-insecure compared to food-secure participants. When the sample was stratified by food insecurity status (yes vs no), consumption of caffeine did not differ by urge urinary incontinence status and consumption of alcohol was lower among participants with vs without urge urinary incontinence. These data indicate that diet alone does not drive the association between urge urinary incontinence and food insecurity. Instead, food insecurity may be a proxy for social inequity, perhaps the greatest driver of disease.

U-shaped association between sleep duration and urgency urinary incontinence in women: a cross-sectional study

BACKGROUND

To investigate the association between sleep duration and urgency urinary incontinence (UUI) among adult women.

METHODS

Cross-sectional data were retrieved from the 2005-2014 National Health and Nutrition Examination Survey. To explore the association between sleep duration and urgency urinary incontinence, multivariable logistic regression and restricted cubic spline (RCS) regression analysis was carried out.

RESULTS

Among 9204 adult women, the weighted urinary incontinence prevalence was  31% for urgency urinary incontinence (UUI). The fully adjusted multivariable model revealed that participants with short (< 7 h) or long (> 9 h) sleep duration were more likely to report UUI compared to participants with normal (7-9 h) sleep duration (OR 1.20, 95% CI 1.03-1.40, p = 0.02, OR 1.40, 95% CI 1.11-1.76, p = 0.005, respectively). Subgroup analysis showed no significant interaction. Furthermore, additional analysis demonstrated a U-shaped correlation between sleep duration and incident UUI.

CONCLUSION

The non-linear association exists between sleep duration and urgency urinary incontinence. Compared with insufficient or excessive sleep, normal sleep duration is related to lower prevalence of urgency urinary incontinence. Future prospective longitudinal studies should be conducted to further investigate and determine the degree of the association between sleep time and urgent urinary incontinence.

Association between oxidative balance score and urinary incontinence in females: results from the national health and nutrition examination survey in 2005-2018

PURPOSE

Oxidative stress plays a crucial role in the pathogenesis of urinary incontinence (UI). This study aimed to assess the association between the oxidative balance score (OBS) and UI in adult females in the United States.

METHODS

The study utilized data from the National Health and Nutrition Examination Survey database, spanning from 2005 to 2018. Weighted multivariate logistic regression, subgroup analyses, and restricted cubic spline regression were conducted to determine the odds ratio (OR) and 95% confidence intervals (95% CI) regarding the association between OBS and UI. Sensitivity analyses were performed to assess the robustness of the findings.

RESULTS

A total of 7304 participants were enrolled in this study. After adjusting for potential confounders, participants with lower OBS were found to have a higher likelihood of experiencing stress, urge, and mixed incontinence (OR, 0.986; 95% CI 0.975-0.998; p = 0.022; OR, 0.978; 95% CI 0.963-0.993; p = 0.004; and OR, 0.975; 95% CI 0.961-0.990; p = 0.001). Lifestyle factors were strongly associated with the prevalence and frequency of UI. The results remained consistent, and no significant interaction effects were observed in the subgroup analyses. The prevalence of three types of UI exhibited a nonlinear inverted U-shaped trend with increasing in OBS and dietary OBS (p for nonlinear < 0.05).

CONCLUSION

Among females, the higher the OBS, the lower the prevalence of UI. Therefore, dietary and lifestyle-related antioxidant therapy for females with UI should receive attention and be subject to further investigation.

Urinary Incontinence, Quality of Life, and Risk Factors in a Geriatric Cohort

INTRODUCTION

The aim of the study was to evaluate the prevalence of urinary incontinence (UI) and its subtypes, associated clinical factors, and impact on quality of life (QoL) in a geriatric population aged 80 years or older.

METHODS

Male and female residents (inclusion criterion: 80 years or older) of three Viennese senior citizen homes were personally interviewed with the aid of a structured questionnaire based on the Bristol Female Lower Urinary Tract Symptom Questionnaire within a 12-month period. UI was defined as any involuntary loss of urine during the past 4 weeks. Several demographic parameters were obtained additionally.

RESULTS

434 participants with a mean age of 86.8 years (women: 87.6 years; men: 86.1 years) were included. UI was present in 52.5% (57% female vs. 23% male, p < 0.001), stress UI affected 36% (41% female vs. 5% male, p < 0.001), urge UI 38% (40.5% female vs. 23% male, p < 0.01), and mixed UI 28% (24% female vs. 5.0% male, p < 0.01). While the overall prevalence of UI remained rather stable in the four age cohorts (80-84 years, 85-89 years, 90-94 years, >94 years), there was a constant decline of SUI paralleled by an increase of UI and - to a lesser extent - of MUI with age. 36.5% (33% female vs. 57% male) participants did not report any negative impact on QoL, while a severe reduction of QoL was present in 31% of cases (35% female vs. 10.0% male). Risk factors for UI and its subtypes included female sex, reduced/no mobility, hysterectomy, and number of births.

CONCLUSION

This study provides data on the high prevalence of UI in a low-morbid geriatric cohort and evaluates gender-specific differences in UI prevalence, associated risk factors, and QoL.

Prevalence of urinary incontinence among women in Saudi Arabia: a cross-sectional study

OBJECTIVE

Urinary incontinence is defined as involuntary loss of urine, a common health condition that is more frequent in women. It disturbs the affected individuals and interferes with their daily activities. This study aimed to estimate the prevalence of urinary incontinence among Saudi women in the western area of the Kingdom of Saudi Arabia.

SUBJECTS AND METHODS

A descriptive cross-sectional design was used for this study. A survey was administered to Saudi women in the western area of the Kingdom of Saudi Arabia ranging in age from 18 to 70 years. The data were collected using the Arabic version of the Questionnaire for Urinary Incontinence Diagnosis. Descriptive statistics were generated by calculating numbers and percentages of information on the prevalence of incontinence in women. p-values < 0.05 were considered statistically significant.

RESULTS

The prevalence of urinary incontinence was 44.2%, with the urge type being the most reported. Stress urinary incontinence was reported by 155 women (15.4%), urgency urinary incontinence by 257 women (25.6%), and mixed urinary incontinence by 102 women (10.15%).

CONCLUSIONS

Urinary incontinence is prevalent in women in Western Saudi Arabia. Age, multiparty obesity, and vaginal surgery are significant risk factors influencing its occurrence.

Teenage Childbearing as an Independent Risk Factor for Stress Urinary Incontinence in American Women

PURPOSE

To evaluate the associations among teenage childbearing (Age at first birth<=19 years old) with later-life risk of stress and urgency urinary incontinence (SUI, UUI) in American women using nationally representative data from America.

MATERIALS AND METHODS

Data from the National Health and Nutrition Examination Survey (NHANES) from 2015 to 2018 were merged to include 2673 women. The question, "How old were you at the time of your first live birth?" was used to assess teenage childbearing. Urinary incontinence was ascertained by self-report. Multivariable logistic regression models were used to assess the association between teenage childbearing and urinary incontinence in American women, controlling for potential confounders.

RESULTS

Among the 2673 women with complete data, the prevalence of SUI was 27.3%, and the prevalence of UUI was 22.1%. Overall, 856 of female had given birth at or before the age of nineteen. Teenage childbearing was significantly associated with SUI (OR=1.9, 95%CI=1.5-2.3, p < 0.001), but teenage childbearing was not associated with UUI (OR=1.2, 95%CI=1.0-1.5, p = 0.0658).

CONCLUSION

After controlling for known risk factors, teenage childbearing seems to be signif-icantly related to female stress urinary incontinence.

The cumulative effect of unmet social needs on noncancerous genitourinary conditions and severity of lower urinary tract symptoms

PURPOSE

There is growing awareness on how social determinants of health may significantly influence health outcomes. The purpose of this study was to investigate the relationship between unmet social needs and the incidence and severity of multiple noncancerous genitourinary conditions.

MATERIALS AND METHODS

A community-based sample of United States adults was recruited electronically to complete questionnaires on clinical and demographic information, urinary symptoms, and social needs. Logistic regression was used to assess the effect between the number of unmet social needs and various noncancerous genitourinary conditions and severity of lower urinary tract symptoms. Model was adjusted for age, gender, race, insurance, and type of living community.

RESULTS

A total of 4,224 participants were included for final analysis. The incidence of all genitourinary conditions assessed was associated with an increasing number of unmet social needs. Additionally, having three or more unmet social needs, as compared to no needs, was associated with an increased risk of all conditions and worse symptoms-including a 23.7% increased risk of interstitial cystitis (95% confidence interval [CI] 18.8%-28.7%, p < 0.001), 21.9% risk of urge urinary incontinence (95% CI 16.8%-27.0%, p < 0.001), and 20.6% risk of overactive bladder (95% CI 15.6-25.7, p < 0.001).

CONCLUSIONS

Unmet social needs are associated with an increased incidence of noncancerous genitourinary conditions as well as worse symptom severity, with multiple unmet social needs displaying a cumulative effect. These findings suggest that there is utility in screening patients for unmet social needs, and that the healthcare system should develop a more integrated approach to manage  patients with urinary conditions.

Association between body mass index, trunk and total body fat percentage with urinary incontinence in adult US population

INTRODUCTION AND HYPOTHESIS

To assess the association of body mass index (BMI), trunk and total body fat percentage with the prevalence and severity of urinary incontinence (UI) stratified by gender among a US adult population.

METHODS

A representative cross-sectional survey of participants aged ≥ 20 years was conducted using the data from the 2011-2018 National Health and Nutrition Examination Survey. Multivariate logistic and linear regression models were used to explore the association among the three obesity measures above with the prevalence and severity of UI.

RESULTS

A total of 6964 individuals (4168 males and 2796 females) enrolled for the final analysis. Among males, the weighted prevalence of UI was 7.8%, with 1.3% stress urinary incontinence, 5.8% urge urinary incontinence and 0.7% mixed urinary incontinence. For females, the weighted prevalence of UI was 54.2%, with 31.9% stress urinary incontinence, 7.0% urge urinary incontinence and 15.6% mixed urinary incontinence. Multivariate logistic regression revealed increased BMI and trunk fat percentage significantly increased odds of UI (BMI: OR = 1.05 [per 1 kg/m²], 95% CI: 1.03-1.07, P < 0.001; trunk fat percentage: OR = 1.15 [per 5% increase in trunk fat percentage], 95% CI: 1.06-1.25, P = 0.002) in females. Similar trends were observed in the severity of UI (BMI: β = 0.07, 95% CI: 0.05-0.09, P < 0.001; trunk fat percentage: β = 0.18, 95% CI: 0.10-0.26, P < 0.001) by a multivariate linear regression. In males, no significant association was observed (BMI: OR = 0.99 [per 1 kg/m²], 95% CI: 0.97-1.02, P = 0.663; trunk fat percentage: OR = 0.95 [per 5% increase in trunk fat percentage], 95% CI: 0.84-1.08, P = 0.430; total fat percentage: OR = 0.94 [per 5% increase in total fat percentage], 95% CI: 0.80-1.10, P = 0.424).

CONCLUSIONS

An increased BMI and trunk fat percentage are significantly associated with higher prevalence and severity of UI in females.

Associations Between Bacterial Vaginosis And Urgency Urinary Incontinence In Women: An Analysis Of Nhanes 2001 To 2004

OBJECTIVE

To investigate the relationship between bacterial vaginosis (BV) and urinary incontinence (UI) in American women.

MATERIALS AND METHODS

Data from the National Health and Nutrition Examination Survey (NHANES) from 2001 to 2004 were merged. Self-collected vaginal swabs were used to assess BV. Urinary incontinence was determined by self-report. Multivariable logistic regression models were used to assess the association between BV and UI in American women, controlling for potential confounders.

RESULTS

Overall, 31.3% of female respondents tested positive for bacterial vaginosis. Women with bacterial vaginosis were more likely to report stress urinary incontinence (SUI) (22.78% vs 17.79%), urgency urinary incontinence (UUI) (12.86% vs 7.26%) and mixed urinary incontinence (MUI) (7.35% vs 4.42%) than women without bacterial vaginosis. In the adjusted analysis, women with bacterial vaginosis had 1.47 times greater odds of urgency urinary incontinence (OR 1.47, 95% CI 1.07 to 2.17, p=0.0160), and bacterial vaginosis did not increase the odds of stress urinary incontinence and mixed urinary incontinence in women.

CONCLUSION

After controlling for known risk factors, bacterial vaginosis seems to be significantly related to female urgency urinary incontinence. However, the cross-sectional nature of this study does not allow the conclusion of causality. Further basic and cohort studies are needed to examine the association of BV with UUI.

Is there concordance between overactive bladder and detrusor overactivity in men with predominant storage urinary symptoms referred to Functional Urology and Urodynamics Units?

OBJECTIVES

To assess the diagnostic concordance of overactive bladder (OAB) and detrusor overactivity (DO) in male patients with predominant storage lower urinary tract symptoms (LUTS) and evaluate their clinical and urodynamic profile according to DO presence and degree of obstruction.

MATERIAL AND METHODS

Epidemiological, cross-sectional multicenter study. A 3-day bladder diary (3dBD), International Prostate Symptom Score (IPSS) and Bladder Control Self-Assessment Questionnaire (B-SAQ) questionnaires were analyzed. Prostate volume was determined by ultrasound. Urodynamic study (UDS) tests were performed. The prevalence of OAB and DO and the degree of clinical concordance (kappa index) were investigated. Descriptive analysis of clinical variables and UDS results was performed, followed by comparisons based on the presence of DO and degree of obstruction.

RESULTS

A total of 445 patients were included. The mean age was (SD) 54.8 (9.9) years. According to 3dBD, 89.9% presented increased urinary frequency, 87.9% nocturia, 72.1% urgency, and 31.9% urge urinary incontinence (UUI). Obstruction was present in 36.8%. Concomitant OAB and DO were present in 54.5%. The degree of diagnostic concordance between OAB and DO was low (κ = 0.1772). There were more patients with DO presenting urgency (3dBD and B-SAQ; p < 0.001), UUI (3dBD; p = 0.008) and nocturia (B-SAQ; p < 0.001). Differences were found in terms of prostate volume, IPSS-voiding, maximum flow (Qmax) and post-void residual (p < 0.05) according to the obstruction degree.

CONCLUSIONS

Approximately 50% of male patients aged 18-65 years old with predominant storage LUTS, referred to specialized units, have both OAB and DO. Obstruction is present on 1/3. Diagnostic concordance between OAB and DO is poor.

School Toileting Environment, Bullying, and Lower Urinary Tract Symptoms in a Population of Adolescent and Young Adult Girls: Preventing Lower Urinary Tract Symptoms Consortium Analysis of Avon Longitudinal Study of Parents and Children

OBJECTIVES

To examine whether the school toilet environment at age 13, including bullying at toilets, is associated with female lower urinary tract symptoms (LUTS) at ages 13 and 19, as little is known about the association among school toilet environment, voiding behaviors, and LUTS in adolescent girls.

METHODS

The sample comprised 3962 female participants from the Avon Longitudinal Study of Parents and Children. At age 13, participants reported on 7 school toilet environment characteristics and a range of LUTS items. At age 19, participants completed the Bristol Female Lower Urinary Tract Symptoms questionnaire.

RESULTS

All toilet environmental factors were associated with at least 1 LUTS outcome at age 13. Holding behavior was associated with all school toilet environmental factors, with odds ratios ranging from 1.36 (95% confidence interval [CI]: 1.05, 1.76) for dirty toilets to 2.38 (95% CI: 1.60, 3.52) for feeling bullied at toilets. Bullying was associated with all daytime LUTS symptoms and nocturia; odds ratios ranged from 1.60 (95% CI: 1.04, 2.07) for nocturia to 2.90 (95% CI: 1.77, 4.75) for urgency. Associations between age 13 school toilets and age 19 LUTS were in the same direction as age 13 LUTS.

CONCLUSION

This is the first examination of associations between school toilets and LUTS. Toileting environments were cross-sectionally associated with LUTS in adolescent girls. While further work is needed to determine whether these associations are causal, school toilet environments are modifiable and thus a promising target for LUTS prevention.

Vitamin D intake and the 10-year risk of urgency urinary incontinence in women

Evidence indicates that higher serum 25-hydroxy vitamin D levels may be associated with decreased prevalence of urgency urinary incontinence (UI), but the impact of vitamin D consumption on development of urgency and mixed UI is unclear. The objective was to assess whether greater vitamin D intake was associated with decreased risk of incident urgency and mixed UI over 10 years using 2 large prospective cohorts of middle-aged and older women. We analyzed 38,101 women from the Nurses' Health Study I (NHS I) and 35,190 women from NHS II who were free of UI at baseline. We followed incident UI, defined as new UI occurring at least monthly, separately by subtype (urgency, mixed, stress UI), from 2002-2012. We categorized vitamin D intake from supplements and diet. We estimated relative risk for developing UI according to vitamin D intake using Cox-proportional hazard models with adjustment for covariates. Median vitamin D intake was 580IU in the older women in NHS I (age range 56-71 at baseline) and 487IU in middle-aged women in NHS II (age range 40-57). Among women taking ≥1000IU of vitamin D, median intake in the older women was 1252IU and 1202IU in the middle-aged women. Among the older women, we found no relation of vitamin D intake to risk of developing UI, across all UI subtypes. In multivariable-adjusted analysis for middle-aged women, the relative risk of developing mixed UI among women taking >1000IU was 0.79 (0.63, 0.99) and for urgency UI was 0.88 (0.71, 1.07), versus <200IU. Risks of developing stress UI were not related to vitamin D intake categories. Overall, we did not find a relationship between vitamin D intake and UI incidence in middle-aged and older women; however, the reported intake was moderate.

Is urinary incontinence associated with sedentary behaviour in older women? Analysis of data from the National Health and Nutrition Examination Survey

BACKGROUND

Urinary incontinence (UI) is a common geriatric syndrome associated with physical and cognitive impairments. The association between type of UI and sedentary behaviour (SB) has not been explored.

AIM

To determine association between moderate-severe UI, or any stress UI (SUI) or any urgency UI (UUI) and SB in community-dwelling older women.

METHODS

Women aged 60 and over from the 2005-2006 cycle of the National Health and Nutrition Examination Survey (NHANES) with objectively measured (accelerometer) and self-reported SB and UI data were selected. Multivariate models exploring association between moderate-severe UI and SB, or SUI and SB, or UUI and SB were analysed using logistic regression adjusted for factors associated with UI.

RESULTS

In the overall sample of 459 older women, 23.5% reported moderate-severe UI, 50.5% reported any SUI and 41.4% reported any UUI. In bivariate analysis objectively measured proportion of time in SB was associated with moderate-severe UI and UUI (p = 0.014 and p = 0.047) but not SUI. Average duration of SB bouts in those with moderate-severe UI or any SUI was no longer than older women reporting no continence issues, but it was significantly (19%) longer in older women with any UUI (mean difference 3.2 minutes; p = 0.001). Self-reported SB variables were not associated with any type of UI. Multivariate analysis showed an association between UUI and a longer average duration of SB bouts (OR = 1.05, 95% CI = 1.01-1.09, p = 0.006) but no association with moderate-severe UI or SUI.

CONCLUSION

UUI was significantly associated with increased average duration of SB bouts in community-dwelling older women. The importance of objective measurement of SB is highlighted and suggests that decreasing time in prolonged sitting may be a target intervention to reduce UUI. Future studies are required to further explore the association between SB and incontinence.

Risk factors and prevalence of urinary incontinence in mid-life Singaporean women: the Integrated Women's Health Program

INTRODUCTION AND HYPOTHESIS

The objective was to identify the prevalence and risk factors for urinary incontinence (UI) in healthy midlife Singaporean women.

METHODS

Healthy women, aged 45-69 years, were assessed for UI and sociodemographic characteristics, including ethnicity, menopausal status, parity, and body mass index (BMI). UI subtypes corresponding to stress (SUI) alone, urge (UUI) alone, mixed (MUI), and leakage (drops only) incontinence were classified using the Urinary Distress Inventory 6 (UDI-6). Risk factors were examined using Chi-squared tests, followed by sequential multivariate logistic regression to estimate adjusted odds ratios (aOR and 95% confidence intervals).

RESULTS

A total of 1,119 women (mean age 56.2 ± 5.2) completed the UDI-6. 52.3% reported any UI; MUI and SUI were the most common, each affecting 20% of women. Post-menopausal women had a lower risk (aOR 0.5 [0.3-0.9]) of SUI, but a higher risk (aOR 4.4 [1.0-19.9]) of UUI compared with premenopausal women. Higher education was negatively associated (aOR 0.3 [0.2-0.7]) with UUI, but positively associated with MUI (aOR 2.3 [1.3-4.0]). Parity (1-2 children) increased the risk of SUI (aOR 1.8 [1.0-3.1]), but reduced the risk of UUI (aOR 0.4 [0.2-0.9]). Obesity was associated with increased risk for MUI (aOR 2.2 [1.4-3.4]) and leakage (aOR 2.0 [1.0-4.1]). Malays and Indians had a higher risk of MUI, having (aOR 2.1 (1.2-3.7) and 1.7 (1.1-2.7) respectively compared with Chinese, a difference mediated by higher BMI.

CONCLUSION

Urinary incontinence is a major morbidity prevalent in healthy midlife Asian women. Post-menopausal status, education level, parity, BMI (and its link with ethnicity) are independent risk factors in this population, and should be incorporated into counseling and targeted interventions.

A Prospective Study of the Association between Physical Activity and Lower Urinary Tract Symptoms in Parous Middle-Aged Women: Results from the Avon Longitudinal Study of Parents and Children

PURPOSE

We examined prospective associations between physical activity and a range of lower urinary tract symptoms in parous middle-aged women.

MATERIALS AND METHODS

We used prospectively collected data on women participating in the ALSPAC (Avon Longitudinal Study of Parents and Children). Physical activity levels were self-reported at a mean ± SD age of 37.2 ± 4.6 years and translated into MET hours per week. A total of 4,126 and 2,770 women reported symptoms of lower urinary tract symptoms, including stress, urgency and mixed incontinence, at 3 and 11.5 years of followup, respectively.

RESULTS

The prevalence of any lower urinary tract symptoms at 3 and 11.5 years of followup was 15% and 23% at a mean age of 40.5 and 49.3 years, respectively. At 3 years of followup women in the highest category of physical activity (43.2 MET hours or more per week) had lower odds of stress incontinence (aOR 0.51, 95% CI 0.32-0.80) than women in the lowest category (0 MET hours per week). At 11.5 years of followup women in the highest category of physical activity had lower odds of stress incontinence (aOR 0.56, 95% CI 0.39-0.82), urgency incontinence (aOR 0.34, 95% CI 0.20-0.67) and mixed incontinence (aOR 0.34, 95% CI 0.19-0.63) compared to women in the lowest physical activity category.

CONCLUSIONS

Greater physical activity is associated with reduced odds of lower urinary tract symptoms, especially stress incontinence, among middle-aged parous women. Further research is necessary to examine the impact of different types of physical activity on lower urinary tract symptoms.

Evaluation of urinary incontinence and quality of life in married women aged between 20 and 49 years (Sakarya, Turkey)

Background/aim: This study aimed to determine the prevalence of urinary incontinence and to evaluate the relationship between urinary incontinence and quality of life in married women. Materials and methods: This is a cross-sectional study conducted among married women aged 20-49 years living in the vicinity of the Çökekler Community Clinic (Family Health Center) in Sakarya, Turkey, from 1 November 2011 to 15 April 2012. The study group consisted of 1161 women. Results: The frequency of urinary incontinence was 71.5% (n = 830). Out of a total of 830 patients with symptoms of urinary incontinence, mixed was the most frequently determined type (60.4%), followed by urge (33.9%) and then stress urinary incontinence (5.8%). The mean scores obtained by women with urinary incontinence from the general health perceptions and social functioning domains of the SF-36 survey were lower (P < 0.05 for each domain). Conclusion: Urinary incontinence was found to be a common problem among women, and it affects quality of life adversely. Recurrent urinary tract infection and advancing age were the key risk factors in the development of urinary incontinence.

Should the visceral peritoneum be closed over mesh in abdominal sacrocolpopexy?

INTRODUCTION AND HYPOTHESIS

Peritonisation of mesh during Abdominal sacrocolpopexy is generally advocated to prevent adhesions to the viscera; however, randomized clinical trials are lacking. In this study; we aimed to investigate whether the mesh peritonisation is clinically significant or not.

MATERIAL METHOD

Thirty-four patients who were operated for the reason of pelvic organ prolapse were included in the study. Patients were divided into two groups by retrospective scanning from the files and surgical reports. Group 1 patients consisted of those who underwent peritonisation and group 2 patients consisted of those who did not in abdominal sacrocolpopexy.

RESULTS

Operative time and the amount of blood lost were statistically less in the group 2. Postoperative pain and analgesic drug requirements were obviously higher in the group 1. Postoperative De novo dyspareunia and urinary urgency were higher in the group 1. There were no statistical differences between the groups in terms of other complications.

CONCLUSION

We noticed that there was no difference between the patients who were peritonized and those who were not in terms of postoperative complications.

Urinary incontinence in women

Urinary incontinence symptoms are highly prevalent among women, have a substantial effect on health-related quality of life and are associated with considerable personal and societal expenditure. Two main types are described: stress urinary incontinence, in which urine leaks in association with physical exertion, and urgency urinary incontinence, in which urine leaks in association with a sudden compelling desire to void. Women who experience both symptoms are considered as having mixed urinary incontinence. Research has revealed overlapping potential causes of incontinence, including dysfunction of the detrusor muscle or muscles of the pelvic floor, dysfunction of the neural controls of storage and voiding, and perturbation of the local environment within the bladder. A full diagnostic evaluation of urinary incontinence requires a medical history, physical examination, urinalysis, assessment of quality of life and, when initial treatments fail, invasive urodynamics. Interventions can include non-surgical options (such as lifestyle modifications, pelvic floor muscle training and drugs) and surgical options to support the urethra or increase bladder capacity. Future directions in research may increasingly target primary prevention through understanding of environmental and genetic risks for incontinence.

Urinary Incontinence of Women in a Nationwide Study in Sri Lanka: Prevalence and Risk Factors

PURPOSE

Urinary incontinence, be stress incontinence or urge incontinence or a mixed type incontinence affects women of all ages. The aim of this study was to describe the prevalence and risk factors of urinary incontinence in Sri Lanka.

MATERIALS AND METHODS

A community based cross-sectional study was performed in Sri Lanka. The age group of the women in Sri Lanka was categorized into 3 age groups: Less than or equal to 35 years, 36 to 50 years of age and more than or equal to 51 years of age. A sample size of 675 women was obtained from each age category obtaining a total sample of 2025 from Sri Lanka. An interviewer-administered questionnaire consisting of two parts; Socio demographic factors, Medical and Obstetric History, and the King's Health Questionnaire (KHQ), was used for data collection. Stepwise logistic regression analysis was performed.

RESULTS

The Prevalence of women with only stress incontinence was 10%, with urge incontinence was 15.6% and with stress and urge incontinence was 29.9%. Stepwise logistic regression analysis showed that the age groups of 36 - 50 years (OR = 2.03; 95% CI = 1.56 - 2.63) and 51 years and above (OR = 2.61; 95% CI= 1.95 - 3.48), Living in one of the districts in Sri Lanka (OR = 4.58; 95% CI = 3.35 - 6.27) and having given birth to multiple children (OR = 1.1; 95% CI = 1.02 - 1.21), diabetes mellitus (OR = 1.97; 95% CI = 1.19 - 3.23), and respiratory diseases (OR = 2.17; 95% CI = 1.48 - 3.19 ) showed a significant risk in the regression analysis.

CONCLUSION

The risk factor, mostly modifiable, if prevented early, could help to reduce the symptoms of urinary incontinence.

Zusammenfassung. Die überaktive Harnblase ist definiert durch einen imperativen Harndrang mit oder ohne Drang-Inkontinenz und ist meist assoziiert mit einer Pollakisurie am Tag und in der Nacht, ohne dass ein Harnwegsinfekt oder eine andere offensichtliche Pathologie zugrunde liegt. Die Prävalenz der überaktiven Harnblase beträgt ab dem 40sten Lebensjahr ca. 17% und nimmt mit steigendem Alter zu. Die damit verbundenen Gesundheitskosten sind enorm. Meist ist die Lebensqualität erheblich eingeschränkt und oft führt die Standard-Therapie mit Antimuskarinika/Beta3-Adrenozeptor-Agonisten zu keiner relevanten Beschwerdebesserung. Doch es gibt neue therapeutische Möglichkeiten: Mit neuromodulativen Verfahren (wie der transkutanen elektrischen Nervenstimulation, der transkutanen oder perkutanen tibialen Nervenstimulation oder der sakralen Neuromodulation) oder Onabotulinumtoxin A-Injektionen in den Detrusor kann auch in aussichtslos scheinenden Situationen oft eine erstaunliche Wirkung erzielt werden.

Macrovascular Complications and Prevalence of Urgency Incontinence in Japanese Patients with Type 2 Diabetes Mellitus: The Dogo Study

Objective Macrovascular diseases and urgency incontinence are common among Japanese patients with type 2 diabetes mellitus. However, little evidence exists regarding the association between stroke and urgency incontinence among patients with type 2 diabetes mellitus. We examined the associations between macrovascular complications and urgency incontinence among Japanese patients with type 2 diabetes mellitus. Methods The study subjects were 818 Japanese patients with type 2 diabetes mellitus. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate?" We adjusted our analyses for sex, age, body mass index, duration of type 2 diabetes, current smoking, current drinking, hypertension, dyslipidemia, glycated hemoglobin, diabetic nephropathy, diabetic retinopathy, and diabetic peripheral neuropathy. Results The prevalence of urgency incontinence was 9.2%. Stroke was independently positively associated with urgency incontinence, with an adjusted odds ratio of 2.34 (95% confidence interval: 1.03-4.95). The associations between ischemic heart disease or peripheral artery disease and the prevalence of urgency incontinence were not significant. Conclusion In Japanese patients with type 2 diabetes mellitus, stroke, but not ischemic heart diseases or peripheral artery disease, was independently positively associated with urgency incontinence.

Incontinence rates after midurethral sling revision for vaginal exposure or pain

BACKGROUND

Midurethral slings have become the preferred surgical treatment for stress urinary incontinence. Midline transection of midurethral sling for dysfunctional voiding is an effective treatment and also has a low rate of recurrent stress incontinence. Recurrent stress incontinence after sling revision for pain and mesh exposure has not been well defined. It is therefore difficult to counsel patients on risk of recurrent stress incontinence when sling revision is performed for pain or mesh exposure.

OBJECTIVE

We examined the rate of postoperative stress incontinence after midurethral sling revision for the indication of mesh exposure or pain, as well as postoperative pain and urinary urgency.

STUDY DESIGN

This is a retrospective cohort of 245 patients undergoing a vaginal midurethral sling revision in a 10-year period for the indication of mesh exposure or pain. Preoperative indication for revision, baseline characteristics, and preoperative reports of stress incontinence, pain, and urgency were collected. The type of sling revision was then categorized into partial or complete removal. A partial removal of the sling was defined as removing only the portion of sling exposed or causing pain. A complete removal of the sling was defined as vaginal removal of sling laterally out to the pubic rami. Subjective reports of stress incontinence, pain, and urgency at short-term (16 weeks) and long-term (>16 weeks) follow-up visits were gathered. The primary outcome of the study was recurrent stress incontinence.

RESULTS

In our cohort of 245 women who underwent midurethral sling revision, 94 patients had removal for mesh exposure (36 partial and 58 complete) and 151 had removal for pain (25 partial and 126 complete). All patients had a short-term follow-up with a mean time of 5.9 ± 2.8 weeks and 69% patients had long-term follow-up with a mean time of 29.1 ± 17.7 weeks. No differences were seen in preoperative reports of stress incontinence, urgency, or pain in either group. In the patients with revision for mesh exposure with no preoperative stress incontinence, there was greater postoperative stress incontinence with complete vs partial removal of sling at short-term (14% vs 42%, P = .03) and long-term (7% vs 59%, P = .003) follow-up. In the patients with revision for pain with no preoperative stress incontinence, there was no statistically significant difference in recurrent stress incontinence with complete sling removal at long-term follow-up (22% vs 56%, P = .07). In the patients with midurethral sling revision for pain, 72% of partial and 76% of complete sling removal had resolution of pain postoperatively (P = .66). No difference was seen in postoperative reports of urgency or pain improvement in either group between partial or complete sling removal.

CONCLUSION

In women undergoing midurethral sling revision for mesh exposure, complete sling removal resulted in higher recurrent stress incontinence compared to partial sling removal. For the indication of pain, both partial and complete sling removal improved pain in the majority of patients, but there was no statistically significant difference in recurrent stress incontinence.

Detailed assessment of incontinence in boys with fragile-X-syndrome in a home setting

Fragile-X-syndrome (FXS) is caused by a mutation on the X chromosome (Xq27.3). Males with a full mutation have typical dysmorphic signs, moderate intellectual disability and psychological disorders. Twenty-five to fifty percent are affected by incontinence. The aim of the study was to assess subtypes of incontinence and psychological problems in children with FXS in their home environments. Twenty-two boys with FXS (mean age 11.0 years) and 22 healthy controls (mean age 11.1 years) were examined with sonography, uroflowmetry, 48-h bladder diary, physical examination, IQ test, parental psychiatric interview and questionnaires regarding incontinence and psychological symptoms in a home setting. Boys with FXS had higher rates of incontinence than controls (59.1 vs. 4.8 %). The most common subtypes in FXS boys were primary non-monosymptomatic nocturnal enuresis, urge incontinence and nonretentive faecal incontinence. 90.9 % boys with FXS had a psychological comorbidity. Incontinence and behavioural symptoms were not associated.

CONCLUSION

Boys with FXS have a higher risk for physical disabilities, psychological disorders and incontinence than healthy boys. Constipation is not a major problem in FXS. As effective treatment is available for children with ID, we recommend offering assessment and therapy to all children with FXS and incontinence.

WHAT IS KNOWN

• Boys with fragile-X-syndrome (FXS) have higher rates of incontinence, psychological disorders and somatic conditions than typically developing boys. What is New: • Constipation is a rare condition in FXS in contrast to other genetic syndromes. • Although incontinence rates are higher, urological findings (uroflowmetry, sonography) are not more pathological per se in FXS.

Factors associated with urinary incontinence in middle-aged women: a population-based household survey

INTRODUCTION AND HYPOTHESIS

The objective was to determine the prevalence of urinary incontinence (UI) and factors associated in a sample of Brazilian middle-aged women.

METHODS

A cross-sectional study was conducted between September 2012 and June 2013 with 749 women. UI was defined as any complaint of involuntary loss of urine. The independent variables were sociodemographic data and health-related habits and problems. Statistical analysis was carried out using Chi-squared test and Poisson regression.

RESULTS

The mean age was 52.5 (±4.4) years. The prevalence of UI was 23.6 %. Of these, 48 (6.4 %) had stress urinary incontinence, 59 (7.8 %) urinary urgency, and 70 (9.5 %) had mixed urinary incontinence. In the final statistical model, self-perception of health as fair/poor/very poor (PR: 1.90; 95 % CI, 1.45-2.49; P < 0.001), ≥1 vaginal deliveries (PR: 1.84; 95 % CI, 1.35-2.50; P < 0.001), higher body mass index (PR: 1.04; 95 % CI, 1.02-1.06; P = 0.001), vaginal dryness (PR: 1.60; 95 % CI, 1.23-2.08; P = 0.001), current or previous hormone therapy (PR: 1.38; 95 % CI, 1.06-1.81; P = 0.019), pre-/perimenopause (PR: 1.42; 95 % CI, 1.06-1.91; P = 0.021), and previous hysterectomy (PR: 1.41; 95 % CI, 1.03-1.92; P = 0.031) were associated with a greater prevalence of UI. Current or previous use of soy products to treat menopausal symptoms was associated with a lower prevalence of UI (PR: 0.43; 95 % CI, 0.24-0.78; P = 0.006).

CONCLUSIONS

Several factors are associated with UI in middle-aged Brazilian women. The results highlight the importance of carrying out interventions aimed at reducing modifiable factors.

Microvascular complications and prevalence of urgency incontinence in Japanese patients with type 2 diabetes mellitus: The dogo study

AIMS

Diabetes was significantly positively associated with urgency incontinence in several epidemiological studies. We examine the association between diabetic neuropathy, which we defined based on neuropathic symptoms, the absence of the Achilles reflex, and/or abnormal vibration perception, and urgency incontinence among Japanese patients with type 2 diabetes mellitus.

METHODS

Study subjects were 742 Japanese patients with type 2 diabetes mellitus, aged 19-70 years, who had undergone blood tests at our institutions. A self-administered questionnaire was used to collect information on the variables under study. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate ?". Diabetic neuropathy was diagnosed if the patients showed two or more of the following three characteristics: neuropathic symptoms, the absence of the Achilles reflex, and/or abnormal vibration perception. Adjustment was made for sex, age, body mass index, duration of type 2 diabetes mellitus, current smoking, hypertension, dyslipidemia, glycated hemoglobin, stroke, coronary artery disease, insulin therapy, diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy.

RESULTS

The prevalence of urgency incontinence was 8.6%. Diabetic neuropathy was independently positively associated with urgency incontinence: the adjusted OR was 2.20 (95%CI: 1.16-4.36). Associations between diabetic retinopathy or nephropathy and the prevalence of urgency incontinence were not significant.

CONCLUSIONS

In Japanese patients with type 2 diabetes mellitus, only diabetic neuropathy was independently positively associated with urgency incontinence. Neurourol. Urodynam. 35:1024-1027, 2016. © 2015 Wiley Periodicals, Inc.

The female urinary microbiome in urgency urinary incontinence

OBJECTIVE

The purpose of this study was to characterize the urinary microbiota in women who are planning treatment for urgency urinary incontinence and to describe clinical associations with urinary symptoms, urinary tract infection, and treatment outcomes.

STUDY DESIGN

Catheterized urine samples were collected from multisite randomized trial participants who had no clinical evidence of urinary tract infection; 16S ribosomal RNA gene sequencing was used to dichotomize participants as either DNA sequence-positive or sequence-negative. Associations with demographics, urinary symptoms, urinary tract infection risk, and treatment outcomes were determined. In sequence-positive samples, microbiotas were characterized on the basis of their dominant microorganisms.

RESULTS

More than one-half (51.1%; 93/182) of the participants' urine samples were sequence-positive. Sequence-positive participants were younger (55.8 vs 61.3 years old; P = .0007), had a higher body mass index (33.7 vs 30.1 kg/m(2); P = .0009), had a higher mean baseline daily urgency urinary incontinence episodes (5.7 vs 4.2 episodes; P < .0001), responded better to treatment (decrease in urgency urinary incontinence episodes, -4.4 vs -3.3; P = .0013), and were less likely to experience urinary tract infection (9% vs 27%; P = .0011). In sequence-positive samples, 8 major bacterial clusters were identified; 7 clusters were dominated not only by a single genus, most commonly Lactobacillus (45%) or Gardnerella (17%), but also by other taxa (25%). The remaining cluster had no dominant genus (13%).

CONCLUSION

DNA sequencing confirmed urinary bacterial DNA in many women with urgency urinary incontinence who had no signs of infection. Sequence status was associated with baseline urgency urinary incontinence episodes, treatment response, and posttreatment urinary tract infection risk.

Female mixed urinary incontinence: a clinical review

IMPORTANCE

Mixed urinary incontinence, a condition of both stress and urge urinary incontinence, is prevalent in 20% to 36% of women and is challenging to diagnosis and treat because urinary symptoms are variable and guidelines for treatment are not clear.

OBJECTIVE

To review the diagnosis and management of mixed urinary incontinence in women, with a focus on current available evidence.

EVIDENCE REVIEW

MEDLINE was searched from January 1, 1992, to December 31, 2013. Additional citations were obtained from references of the selected articles and reviews. Articles that discussed the prevalence, diagnosis, results, and treatment of mixed urinary incontinence were selected for review. Evidence was graded using Oxford Centre for Evidence-Based Medicine levels of evidence for treatment recommendations.

FINDINGS

The MEDLINE search resulted in 785 articles. After selection and obtainment of additional citations, a total of 73 articles were reviewed. There is high-quality (level 1) evidence for treating urinary incontinence with weight loss, for treating stress urinary incontinence by performing anti-incontinence procedures of both traditional and mid-urethral slings and retropubic urethropexies, and for managing urge urinary incontinence with anticholinergic medications. However, direct high-quality evidence for treatment of women with mixed urinary incontinence is lacking, as are clear diagnostic criteria and management guidelines.

CONCLUSION AND RELEVANCE

High-quality, level 1 evidence for urinary incontinence therapy can guide clinicians in the treatment of the components of mixed urinary incontinence. Because high-quality evidence is lacking regarding the treatment of mixed urinary incontinence, treatment generally begins with conservative management emphasizing the most bothersome component. Randomized trials in women with mixed urinary incontinence populations are needed.

Improving the management of urinary incontinence

Urinary incontinence (UI) is the complaint of any involuntary loss of urine and is a common condition that is likely to be under-reported. In the UK, the prevalence is estimated to be 17-40%, and rates are higher in the elderly. UI is more common in women than men. Its frequency increases with age, parity, high BMI, and associated comorbidities. The common types are stress UI, overactive bladder (OAB) or urge UI, and mixed UI a combination of the two. In stress UI there is involuntary loss of urine that occurs in association with an increase in intra-abdominal pressure. OAB is caused by overactivity of the detrusor muscle. This may be idiopathic or secondary to lesions affecting the motor or sensory pathways to the muscle. The history should include the circumstances in which the incontinence occurs, the duration and how it affects the patient's quality of life. The initial assessment should include enquiring for symptoms of urinary tract infection and carrying out a urine dipstick test. Abdominal examination should exclude a large pelvic-abdominal mass and a palpable bladder post micturition. Vulval-vaginal examination should assess for atrophic vaginitis and prolapse, masses and pelvic floor muscle contraction. Involving a skilled continence nurse or dedicated pelvic physiotherapist will improve care and can reduce referrals to secondary care. When conservative measures for OAB are unsuccessful, the next step is pharmacological treatment. Referral to secondary care should be offered when the response to two drugs has not been satisfactory. For stress UI, referral is indicated after failure of pelvic floor muscle training.

Economic burden of urgency urinary incontinence in the United States: a systematic review

BACKGROUND

The International Continence Society (ICS) identifies several urinary incontinence (UI) subtypes: urgency urinary incontinence (UUI), stress UI (SUI), and mixed UI (MUI). UUI is a common symptom of overactive bladder (OAB) syndrome. Based on the current ICS definition of OAB, all patients with UUI have OAB, whereas not all patients with OAB have UUI. Because UUI is a chronic condition that is expected to increase in prevalence as the population of elderly individuals grows, it is important to understand its economic burden on society and patients and its cost components. 

OBJECTIVE

To summarize the published English language medical literature on estimates of the economic burden of UUI in the United States from a societal and patient perspective, including direct costs (diagnosis, treatment, routine care [including incontinence pads], and UUI-associated comorbidities/complications); indirect costs (lost wages by patients and caregivers and lost work productivity due to absenteeism and presenteeism); and intangible costs (pain, suffering, and decreased health-related quality of life). 

METHODS

A PubMed search of the literature for articles on the economic burden of UUI in the United States was conducted using the search terms (urgency urinary incontinence OR urge incontinence OR mixed incontinence OR overactive bladder) AND (burden OR cost OR economic) AND (United States), with limits for English language, publication from 1991 to 2011, humans, and adults (19+ years). Only primary articles of non-neurogenic UUI in the United States were retained. 

RESULTS

Seven studies were identified that included data on the economic burden of UUI in the United States from a societal and patient perspective. Although estimates of the total economic burden of UUI include direct, indirect, and intangible costs, none of the 7 U.S. studies included all of these cost components. Furthermore, the costs of UUI often could not be fully extracted from the costs of OAB, which include patients with and without UUI, or the costs of other types of UI. The most recent cost analysis incorporated OAB with UUI prevalence rates and data on use of each cost component to calculate the total annual direct costs in 2007 for adults aged ≥ 25 years. The estimated total national cost of OAB with UUI in 2007 was $65.9 billion, with projected costs of $76.2 billion in 2015 and $82.6 billion in 2020. This 2007 estimate was markedly higher than those reported in older studies. Direct costs are the main driver of the overall cost of UUI in the United States. Studies that assessed patient costs indicated that the personal costs of routine care items for UUI and MUI represent a meaningful contribution to the overall economic burden of these conditions. These substantial personal expenditures may explain why patients reported that they were willing to pay considerable amounts for a treatment that would reduce the frequency of their UUI episodes. 

CONCLUSIONS

UUI in the United States is associated with a substantial economic burden from both a societal and patient perspective. Studies evaluating the impact of interventions that reduce the frequency of UUI 
episodes on the overall economic burden of UUI are warranted. 

[Relationship between urinary incontinence and pelvic organ prolapse]

BACKGROUND

Urinary incontinence affects up to 70% of women and pelvic organ prolapse has a prevalence of 41% in postmenopausal women over 60 years, but most are not clinically affected.

OBJECTIVE

Sought to assess the relationship of pelvic organ prolapse in patients with urinary incontinence diagnosed by urodynamic and which of the sub-types is related to a greater extent.

MATERIAL AND METHODS

We performed an observational, retrospective, descriptive, in which we reviewed records of patients with symptoms of urinary incontinence undergoing urodynamic study, evaluating a total of 85 patients.

RESULTS

Prolapse was noted in mixed incontinence by 80%, compared to 46.9% with urge incontinence or stress incontinence 34.9%, p 0.034. 89.5% of women with prolapse had some form of incontinence, associated with an OR = 2.38 (CI 1844-3078, p = 0.023).

Constipation in children with isolated overactive bladders

OBJECTIVE

To evaluate the prevalence of constipation in children with isolated overactive bladder (IOAB) and no micturition complaints.

MATERIALS AND METHODS

A questionnaire was used to evaluate constipation in 51 children with IOAB, as well as in a control group of 74 children between the ages of 4 and 14 years. The Rome III criteria for children were used to assess constipation. IOAB was defined as the presence of symptoms such as urgency with or without daytime incontinence or frequency, a bell-shaped uroflow, and no post-residual urine.

RESULTS

Mean patient ages were 7.94 (±2.8) and 8.28 (±3.4) years in the OAB and control group, respectively (p = 0.54). Twenty-eight (54.9%) of the OAB group were girls, and 34 (45.9%) were girls in the control group (p = 0.32). More of the children with IOAB had constipation than those without urinary symptoms (54.9% vs. 29.7%, p = 0.005; or 2.87, 95% CI: 1.3-6.0). The results were statistically significant regarding the following Rome III criteria: "history of stool retention", "presence of painful or hard bowel movements", "the presence of a large fecal mass in the rectum" and "large diameter stools which may obstruct the toilet". Within the group with OAB, constipation was more common among males (p = 0.05). There was no association between the type of OAB symptoms and constipation. The average dysfunctional voiding symptom score was 9.76 (±4.1). Eleven children (21.6%) presented alterations on ultrasound. Girls with OAB presented more frequently with UTI than boys (18 vs. 10, p = 0.13).

CONCLUSION

This was the first comparative study with respect to constipation in children with IOAB and without urinary symptoms. Children with IOAB have a greater risk of having constipation compared to those with no urinary symptoms.

[The treatment of female urinary incontinence]

Urinary incontinence isn't a fatality anymore. This pathology, which handicaps a large majority of the female population, should be treated in a global approach of the pelvic floor pathologies. Up to 25% of women over 65 years will suffer from urinary incontinence but age is not a discriminating factor in the appearance of this pathology. Comportemental and physiotherapeutical treatments are primordial. In case of lack of good results, surgery may offer good results in urinary incontinence and pharmacological treatment for urge urinary incontinence. In this text, the most common treatment options will be discussed.

Depressive symptoms and treatment of women with urgency urinary incontinence

INTRODUCTION AND HYPOTHESIS

Depression is more common in patients with urinary incontinence (UI). Drug or rehabilitation therapy have been shown to be effective in reducing urgency UI (UUI) symptoms, but whether these treatments can ameliorate the negative impact of UUI on the psychological aspects of quality of life is unclear.

METHODS

A secondary analysis of an assessor-blinded randomized controlled trial was performed. The number of depressive symptoms was the primary outcome as measured by the Center for Epidemiologic Studies Depression scale (CES-D).

RESULTS

Thirty-six (22%) subjects had a CES-D score >16 at baseline, the cutoff for having depressive symptoms. A significant association was found between having a CES-D score >16 and lower quality of life related to UI at baseline. The mean CES-D score among those with depressive symptoms at baseline was significantly reduced throughout the study, with a mean of 23.7 at baseline, to 18.3 and 15.2 at the 3-month and 1-year follow-up (p < 0.001), respectively. The number of participants who had depressive symptoms decreased during the study period only in the physical therapy groups, from 31 at baseline to 28 and 25, at 3 and 12 months, respectively, while there was no such change in the drug group.

CONCLUSIONS

Patients with UUI who had depressive symptoms showed significant improvement in their depressive symptoms with treatment over 1 year. This improvement occurred regardless of the type of treatment. This study emphasizes the increasingly recognized problem of undiagnosed depression among middle-aged women with UUI.

Urinary incontinence, depression and posttraumatic stress disorder in women veterans

OBJECTIVE

To study associations between urinary incontinence (UI) symptoms, depression, and posttraumatic stress disorder in women veterans.

STUDY DESIGN

This cross-sectional study enrolled women 20 to 52 years of age registered at 2 midwestern US Veterans Affairs Medical Centers or outlying clinics within 5 years preceding study interview. Participants completed a computer-assisted telephone interview assessing urogynecologic, medical, and mental health. Multivariable analyses studied independent associations between stress and urgency UI and depression and posttraumatic stress disorder.

RESULTS

Nine hundred sixty-eight women mean aged 38.7 ± 8.7 years were included. Of these, 191 (19.7%) reported urgency/mixed UI and 183 (18.9%) stress UI. Posttraumatic stress disorder (odds ratio, 1.8; 95% confidence interval, 1.0-3.1) but not depression (odds ratio, 1.2; 95% confidence interval, 0.73-2.0) was associated with urgency/mixed UI. Stress UI was not associated with posttraumatic stress disorder or depression.

CONCLUSION

In women veterans, urgency/mixed UI was associated with posttraumatic stress disorder but not depression.

Associations between subjective overactive bladder symptoms and objective parameters on bladder diary and filling cystometry

INTRODUCTION AND HYPOTHESIS

A study was conducted to assess associations between different overactive bladder (OAB) symptoms and their outcomes on bladder diary and filling cystometry parameters.

METHODS

We performed a retrospective cohort study in database of 6,876 Urinary Distress Inventories, 3,185 bladder diaries and 2,153 filling cystometries from women referred to our urogynecological center between 2003 and 2009. Women were dichotomized into two groups. Group I: those women without symptoms, and those with symptoms that were not bothersome. Group II: women with bothersome symptoms. Data obtained from bladder diaries were: daytime urinary frequency, nocturnal frequency, minimum voided volume, maximum voided volume, average voided volume, and incontinence episodes. From filling cystometries, volumes at first desire to void, normal desire to void, strong desire to void and maximum cystometric capacity, were extracted. Univariate and multiple linear regression analysis were performed to determine associations between OAB symptoms and bladder diary and filling cystometry measurements.

RESULTS

After multivariate analysis the objective daytime frequency was most strongly associated with the frequency symptom (β 0.27, p < 0.05), night time frequency with the nocturia symptom (β 0.40, p < 0.05) and the number of incontinence episodes with the urge incontinence symptom (β 0.37, p < 0.05). Both frequency and nocturia symptoms were significantly associated with bladder diary and cystometry filling volumes, and their effect size was the same. The urgency symptom proved to be poorly associated with objective parameters.

CONCLUSIONS

In contrast to the frequency and nocturia symptom, the urgency symptom is poorly associated with objective parameters on bladder diary and filling cystometry. Therefore, the current practice of using frequency and incontinence episodes in outcome research of OAB trials is justified.

Urinary incontinence in women and its relation with pregnancy, mode of delivery, connective tissue disease and other factors

OBJECTIVES

The aim of this study was to determine the relationship between urinary incontinence (UI) and parameters such as pregnancy, mode of delivery and other factors.

MATERIAL AND METHODS

The study was based on a questionnaire administered to 761 patients. After their age, menopausal status, number of pregnancies, number of deliveries and history of connective tissue disease (CTD) were recorded, the data were analyzed using a chi2 test.

RESULTS

In patients who are post-menopausal and over 40, both stress incontinence (SI) and urge incontinence (URI) were found to be significantly higher. It was also established that both SI and URI increased with the number of pregnancies. As the number of normal vaginal deliveries increased, the rate of both SI and URI increased, while increases in the number of cesarean sections affected neither SI nor URI. Among women who had had abortions, the rate of SI was higher, and it increased as the number of abortions increase. Neither the occurrence of abortions nor increased numbers of abortions influenced the rate of URI. In patients with CTD, both SI and URI increase.

CONCLUSIONS

Urinary incontinence in women seems to be influenced by the mode of delivery, menopause, age and CTD.

Urinary incontinence self-report questions: reproducibility and agreement with bladder diary

INTRODUCTION AND HYPOTHESIS

This study aims to measure self-report urinary incontinence questions' reproducibility and agreement with bladder diary.

METHODS

Data were analyzed from the Reproductive Risk of Incontinence Study at Kaiser. Participating women reporting at least weekly incontinence completed self-report incontinence questions and a 7-day bladder diary. Self-report question reproducibility was assessed and agreement between self-reported and diary-recorded voiding and incontinence frequency was measured. Test characteristics and area under the curve were calculated for self-reported incontinence types using diary as the gold standard.

RESULTS

Five hundred ninety-one women were included and 425 completed a diary. The self-report questions had moderate reproducibility and self-reported and diary-recorded incontinence and voiding frequencies had moderate to good agreement. Self-reported incontinence types identified stress and urgency incontinence more accurately than mixed incontinence.

CONCLUSIONS

Self-report incontinence questions have moderate reproducibility and agreement with diary, and considering their minimal burden, are acceptable research tools in epidemiologic studies.

An investigation of the relationship between anxiety and depression and urge incontinence in women: Development of a psychological model

OBJECTIVES

The study investigated the association between anxiety and depression and urge incontinence and the direction of causal pathways between these variables.

DESIGN

A prospective longitudinal postal survey.

METHOD

A random sample of women aged 40 years or more, registered with a general practitioner in Leicestershire or Rutland, was mailed a postal questionnaire. The questionnaire included questions on general health, urinary symptoms and the Hospital Anxiety and Depression Scale (HADS). In total, 12,568 women responded to the baseline postal survey (65.3% response rate) and 9,596 to the first annual follow-up (79.8% response rate). The prevalence and one-year incident rates of these symptoms were compared and contrasted, whilst controlling for confounding variables.

RESULTS

A significant proportion of women with urge incontinence reported symptoms of anxiety (56.6%) and depression (37.6%). Anxiety and depression were associated with a number of urinary symptoms and were not exclusive to urge incontinence. Incident cases of anxiety and depression were predicted by the presence of urge incontinence at baseline. Incident cases of urge incontinence were predicted by anxiety at baseline, but not depression. Anxiety, urge incontinence and frequency appeared to interact and exacerbate each other.

CONCLUSIONS

The findings demonstrated the relevance of emotional factors in the development and maintenance of urge incontinence. Currently, assessment and treatment protocols for urge incontinence concentrate on physical symptoms and toilet behaviours. A more integrated psychological model of urge incontinence is proposed.

Impact of solifenacin on diary-recorded and patient-reported urgency in patients with severe overactive bladder (OAB) symptoms

OBJECTIVE

It is widely recognized that patient perception of overactive bladder (OAB) symptoms can vary considerably from mild to severe bother. This post hoc analysis reports outcomes in patients with severe OAB symptoms at baseline taken from the VESIcare Efficacy and Safety in PatieNts with Urgency Study (VENUS).

METHODS

VENUS was a 12-week, randomized, double-blind, placebo-controlled trial of solifenacin (5 or 10 mg/day, flexibly dosed) in OAB patients. The primary endpoint in VENUS was mean change from baseline to study end in urgency episodes/day using 3-day bladder diaries. Secondary endpoints included other diary endpoints (frequency, incontinence, and nocturia), warning time (WT; time between first sensation of urgency to voiding), and patient-reported outcome (PRO) measures of urgency (the Indevus Urgency Severity Scale [IUSS] and Urgency Perception Scale [UPS]) and of symptom bother and health-related quality of life (HRQL) (the Patient Perception of Bladder Condition [PPBC] and Overactive Bladder Questionnaire). For this analysis, severe OAB was defined as baseline PPBC score ≥5 (1 = no problems, 6 = many severe problems).

TRIAL REGISTRATION

NCT00454896.

RESULTS

In total, 158/707 (22.3%) patients in the full analysis set (FAS) reported severe OAB symptoms. Solifenacin reduced mean urgency episodes/day versus placebo in the severe subgroup (-4.6 vs. -3.1, p = 0.1150), similar to the significant reduction observed in the FAS (-3.9 vs. -2.7, p < 0.0001). Solifenacin also improved the other diary endpoints and PRO measures in the severe subgroup; these changes were consistent with the significant solifenacin- versus placebo-related improvements for the FAS. Treatment-emergent adverse events were mostly mild/moderate, and few patients taking solifenacin or placebo discontinued treatment in the severe subgroup (4.5% vs. 6.5%) or FAS (6.5% vs. 4.6%). Key limitations are that VENUS was not powered to detect treatment differences in subgroups, and that the lack of a standardized definition of OAB symptom severity may limit the generalizability of the findings.

CONCLUSIONS

Patients with severe OAB symptoms showed objective and subjective improvements in symptoms, symptom bother, HRQL, and urgency severity with solifenacin similar to the FAS. Solifenacin was also well-tolerated in this subgroup.

[Epidemiological study of women adults with mixed urinary incontinence in China]

OBJECTIVE

To investigate the prevalence and the epidemiological factors of female mixed urinary incontinence (MUI) in China.

METHODS

In February to July 2006, 19 024 subjects aged over 20 years old in 6 Chinese regions including Northwest, Southwest, Northern China, Eastern China, Northeast and South China were selected. Questionnaires were used to investigate the general characters and the lower urinary tract symptoms in these subjects.

RESULTS

The overall prevalence of mixed urinary incontinence was 9.4% among these women and it increased with advancing age. In multiple logistic models, age, vaginal delivery, constipation, pelvic organ prolapse, chronic pelvic pain, respiratory system disease, menstrual disorder, urinary system disease, alcohol consumption, pelvic surgery, obesity as well as high educational level were independent risk factors for mixed urinary incontinence.

CONCLUSION

The prevalence of MUI increases with advancing age. Vaginal delivery, constipation and pelvic organ prolapse are risk factors for mixed urinary incontinence in China while high educational level is a protective factor.

Urinary urgency - translating the evidence base into daily clinical practice

AIM

To consider the currently available knowledge and understanding of the symptom of urgency.

MATERIALS & METHODS

Each faculty member reviewed the literature base of a different aspect of urgency and along with their personal clinical experience provided a base of evidence for discussion.

RESULTS

This overview summarises relevant published literature and the current clinical experience of the authors.

DISCUSSION

Whilst the mechanisms producing the sensation of urgency are still not fully understood and we are working within a definition that may complicate measurement and treatment, our pressing need is to effectively manage our patients for whom the practical nature of urgency can be all too apparent.

CONCLUSION

Health care professionals have an important role to play today in helping to alleviate the widespread problem of urgency and its consequences.
