Lower Urinary Tract Symptoms and Overactive Bladder in a Large Cohort of Older Poles-A Representative Tele-Survey.

A reliable reference of population-based parameters for lower urinary tract symptoms (LUTS) and overactive bladder (OAB) is lacking for the elderly. Thus, the objective of this study was to estimate the prevalence, bother, effect on quality of life, and treatment-related behavior for LUTS and OAB in a large population-level cohort of Polish adults aged ≥ 65 years. We used data from the telephone LUTS POLAND survey. Respondents were categorized by sex, age, and residence. All LUTS and OAB were assessed with validated questionnaires and a standard protocol based on the International Continence Society definitions. The mean (standard deviation) age of 2402 participants (60.4% women) was 72.5 (6.7) years. The prevalence of LUTS was 79.5% (men: 76.6%; women: 81.4%), and the prevalence of OAB was 51.4% (men: 49.4%; women: 52.8%). The prevalence of both conditions increased with age. The most prevalent symptom was nocturia. LUTS and OAB were often bothersome, and almost half of participants who reported LUTS or OAB had decreased quality of life related to their urinary functioning. Nevertheless, only one third of participants sought treatment for their bladder problems, and most of these participants received treatment. We did not observe differences between urban and rural areas in all analyzed population-level parameters. LUTS and OAB were prevalent conditions with significant bother and negative effects on quality of life among Polish adults aged ≥ 65 years. Nevertheless, most affected respondents had not sought treatment. Thus, for older persons, there is a need to increase public awareness about LUTS and OAB, and the negative effects of LUTS and OAB on healthy aging. In addition, greater government and healthcare system resources are needed to better manage LUTS and OAB in older patients.

The Prevalence of Lower Urinary Tract Symptoms and Overactive Bladder in South Korea: A Cross-Sectional, Population-Based Study.

PurposeLower urinary tract symptoms (LUTS) affect over half of the adults’ population worldwide, with an increasing prevalence among the older age groups. Therefore, with the increasing elderly population, LUTS is an important disease, highlighting the need for accurate data on its prevalence. This present study aimed to investigate the prevalence of LUTS in South Korea.MethodsThe study targeted individuals aged at least 19 years nationwide. We conducted computer-assisted telephone interviews, 80% mobile random digital dialing (RDD) sampling frame, and 20% landline RDD sampling frame between April and May 2020. Questionnaires included The International Prostate Symptom Score (IPSS), the overactive bladder symptom score (OABSS), and the characteristics of respondents. Current International Continence Society definitions were used for individual LUTS and OAB.ResultsThere were 2,000 respondents, 1,009 (50.4%) were women and 546 (27.3%) were aged ≥60 years. Based on our IPSS questionnaire survey results, 77.9% of the respondents had LUTS; 63.7% had mild symptoms (1–7), 11.7% had moderate symptoms (8–19), and 2.4% had severe symptoms (20–35). The prevalence and severity of LUTS increased with age with 22.1% of respondents aged 60 years and above complaining of moderate or severe LUTS. According to the survey through OABSS, the prevalence of OAB was 9.6%, males were 10.3% and females were 9.0%.ConclusionsBased on our survey results, 77.9% of the Korean adult population (over the age of 19) experienced at least one LUTS, and the severity increased with age. The prevalence and severity of OAB increased with age, especially after 40 years; the prevalence of OAB was 9.6%, and 13.4% of them were over 60 years old.

What is the real burden of the overactive bladder? Results from a national prevalence study.

To describe the prevalence of overactive bladder determining patient-reported outcome measures (PROMS) and potential risk factors. A cross-sectional population-based study to estimate lower urinary tract symptoms (LUTS) prevalence in the Colombian population was performed (COBaLT study). Overactive bladder (OAB) was assessed using 2002 International Continence Society definitions and the Report on the Terminology for Female Pelvic Floor Dysfunction. PROMS were included to evaluate participant's perceptions of health-related quality of life (QoL). Spanish validated questionnaires were used, including the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) and Patient Perception of Bladder Condition (PPBC) scale. A total of 1060 individuals were assessed. The mean age of participants was 42.2 years, and most participants were Hispanic (93.15%). The overall prevalence of OAB syndrome was 31.70%, and it was more frequently reported in women than in men (39.25% vs. 24.15%). Most participants with OAB did not perceive their symptoms as bothersome. The most bothersome symptom, associated with moderate/severe impact in QoL was urinary urgency. According to the PPBC questionnaire 75.6% of the participants reported that their bladder condition does not cause any problem, while 11.% reported moderate to severe bother. The multivariable model showed high blood pressure and anxiety were associated with OAB in men. In females, depression, obstructive sleep apnea, IBS, and pelvic organ prolapse were associated with OAB syndrome. Using the symptomatic definition of OAB can overestimate the real impact and burden of the condition, and treatment should be targeted to those symptomatic patients with QoL impairment as they would benefit from further management. The questionnaires seem to overestimate the condition, since we assessed it from a PROMS perspective there is not such a marked QoL impact.

The Association Between Constipation and Lower Urinary Tract Symptoms in Parous Middle-Aged Women: A Prospective Cohort Study.

Objective: To examine the prospective association between constipation and risk of developing lower urinary tract symptoms (LUTS) in parous middle-aged women.Materials and Methods: The study uses data from 3,729 women from the Avon Longitudinal Study of Parents and Children who provided self-reports of medication intake for constipation at two time points (Baseline): 2001–2003 and 2003–2005. Women with LUTS at baseline were excluded. After 10 years of follow-up, women provided self-reports of LUTS using an adapted version of the International Consultation on Incontinence Questionnaire on Female LUTS. LUTS were categorized according to International Continence Society definitions as stress urinary incontinence (UI), urgency UI, mixed UI, nocturia, increased daytime frequency, urgency, hesitancy, and intermittency. LUTS were considered present if symptoms were reported to occur at least “sometimes” for all subtypes, except for increased daytime frequency (≥9 times) and nocturia (≥2 times nightly).Results: At follow-up, the prevalence of any LUTS was 40%. Women (mean age 43.3 years, standard deviation 0.5), who took medication for constipation at either time point had increased risks of urgency (adjusted relative risks [RRs] = 1.35; 95% confidence interval [CI] 1.04–1.95) and hesitancy (adjusted RR = 1.72; 95% CI 1.04–3.01) compared with women who reported not using medication for constipation at either time point. The risk of urgency (adjusted RR = 1.94; 95% CI 1.15–3.29) and hesitancy (adjusted RR = 1.78; 95% CI 1.03–4.19) was greater for women who reported taking medication for constipation at both time points. There was no evidence that constipation was associated with stress UI, urgency UI, mixed UI, nocturia, increased daytime frequency, and intermittency.Conclusion: Constipation is prospectively associated with an increased risk of urgency and hesitancy among parous middle-aged women. If further research finds evidence that this association is causal, this implies that women should seek treatment to alleviate constipation to reduce their consequent risk of developing these LUTS.

Population-Level Prevalence, Bother, and Treatment Behavior for Urinary Incontinence in an Eastern European Country: Findings from the LUTS POLAND Study.

Objectives: Population-level data are lacking for urinary incontinence (UI) in Central and Eastern European countries. Therefore, the objective of this study was to estimate the prevalence, bother, and behavior regarding treatment for UI in a population-representative group of Polish adults aged ≥ 40 years. Methods: Data for this epidemiological study were derived from the larger LUTS POLAND project, in which a group of adults that typified the Polish population were surveyed, by telephone, about lower urinary tract symptoms. Respondents were classified by age, sex, and place of residence. UI was assessed with a standard protocol and established International Continence Society definitions. Results: The LUTS POLAND survey included 6005 completed interviews. The prevalence of UI was 14.6–25.4%; women reported a greater occurrence compared with men (p < 0.001). For both sexes, UI prevalence increased with age. Stress UI was the most common type of UI in women, and urgency UI was the most prevalent in men. We did not find a difference in prevalence between urban and rural areas. Individuals were greatly bothered by UI. For women, mixed UI was the most bothersome, whereas for men, leak for no reason was most annoying. More than half of respondents (51.4–62.3%) who reported UI expressed anxiety about the effect of UI on their quality of life. Nevertheless, only around one third (29.2–38.1%) of respondents with UI sought treatment, most of whom received treatment. Persons from urban and rural areas did not differ in the degrees of treatment seeking and treatment receiving. Conclusion: Urinary incontinence was prevalent and greatly bothersome among Polish adults aged ≥ 40 years. Consequently, UI had detrimental effects on quality of life. Nonetheless, most affected persons did not seek treatment. Therefore, we need to increase population awareness in Poland about UI and available treatment methods, and we need to ensure adequate allocation of government and healthcare system resources.

Prevalence, Bother and Treatment Behavior Related to Lower Urinary Tract Symptoms and Overactive Bladder among Cardiology Patients.

Purpose: The aim of this study was to measure, at the population level, the prevalence, bother, and treatment-related behavior for lower urinary tract symptoms (LUTS) and overactive bladder syndrome (OAB) in a large cohort of cardiology patients. Methods: This report is a further analysis of data from LUTS POLAND, a computer-assisted telephone survey that reflected the entire Polish population, stratified by age, sex, and place of residence. LUTS and OAB were assessed by a standardized protocol, the International Continence Society definitions, and validated questionnaires. In addition, all participants provided information regarding their behavior as it related to LUTS treatment. Results: Overall, 6005 participants completed interviews, and 1835 (30.6%) had received treatment by cardiologists. The prevalence of LUTS was 73.3% for cardiology participants compared with 57.0% for respondents who were not treated by cardiologists (p < 0.001). There were no differences between men and women in LUTS prevalence for cardiology patients. Nocturia was the most prevalent LUTS. LUTS were often bothersome, and storage symptoms were more bothersome than voiding or postmicturition symptoms. The prevalence of OAB syndrome was 50.7% in cardiology patients, higher than in noncardiology participants (36.6%, p < 0.001), and more women were affected than men. Only one-third of cardiology patients who reported LUTS were seeking treatment for LUTS, and most of them received treatment. There were no differences between persons living in urban and rural areas. Conclusions: LUTS and OAB were highly prevalent among cardiology patients. Although LUTS were often bothersome in this unique population, we found that the seeking of treatment for LUTS was minimal. These results highlight the need for cooperation between cardiologists and urologists.

Prevalence and bother of lower urinary tract symptoms and overactive bladder in Poland, an Eastern European Study

The prevalence of lower urinary tract symptoms (LUTS) and overactive bladder (OAB) has been measured by population-based investigations in many parts of the world. However, data are lacking for Eastern Europe, and there has not been any large population-representative study in any country of this region. Therefore, the aim of this study was to evaluate the prevalence and associated bother of LUTS and OAB in a population-representative sample of persons aged ≥ 40 years in Poland. This investigation was conducted as a computer-assisted telephone interview. The survey sample was stratified by age, sex, and place of residence to reflect the entire Polish population. LUTS and OAB were assessed by a standardized protocol based on the International Continence Society definitions and validated questionnaires. Of 6005 participants, 57% were women, and the mean age (range) was 60.7 (40–93) years. The prevalence of LUTS was 69.8% (men 66.2%; women 72.6%). There was no difference in prevalence between urban and rural areas. LUTS were often bothersome among men and women, but women were more likely to be bothered compared with men. There were also statistically significant correlations between the frequency and the bother intensity of each of the LUTS. The prevalence of OAB was higher in women (39.5%) than in men (26.8%), and OAB increased with age. Lastly, LUTS had detrimental effects on the quality of life because one third of the participants had concerns about their urinary-specific quality of life. This investigation was the first nationwide, population-representative epidemiological study of LUTS and OAB in an Eastern-European country. LUTS were highly prevalent, often bothersome, and had negative effects on the quality of life of men and women aged ≥ 40 years. Our findings are comparable with other epidemiologic studies of LUTS and OAB conducted in different regions of the world.Trial registration: NCT04121936.

Valsalva urethral profile (VUP): A urodynamic measure to assess stress urinary incontinence in women.

We aimed to assess the value of the Valsalva urethral profile (VUP) in case of stress urinary incontinence (SUI). Six hundred and ninety-four women without pelvic organ prolapse were included in this prospective monocentric study. SUI was diagnosedfrom symptoms using the International Continence Society definition, and severity using two validated questionnaires (USP and ICIQ-SF). The urodynamic parameters studied were maximal urethral closure pressure (MUCP) and functional length (FL). Both were performed at rest, during a Valsalva maneuver (v-MUCP and v-FL) and again at rest. Correlation analyses and ROC curves were used to assess the value of the clinical and urodynamic measurements. In our population, based on the questionnaires, 172 (24.8%) women were diagnosed with pure SUI on symptoms, 71 (10.2%) with urgency urinary incontinence and 392 (56.5%) with mixed urinary incontinence; 59 (8.5%) women were continent. The v-MUCP was the most correlated parameter to the severity of SUI (ρ: -0.63) and the most predictive of SUI risk, with a threshold value of 35 cm H2 O (Se = 0.82, Sp = 0.86). The v-FL was significantly shortened in case of SUI. The v-MUCP and v-FL are global measurements of urethral resistance during stress. With a threshold value of 35 cm H2 O, the v-MUCP was the most discriminating parameter for the diagnosis of SUI, with a good reliability.

MP31-09 HOW DO WE DIAGNOSE DETRUSOR UNDERACTIVITY? THE POTENTIAL OF PARAMETERS CALCULATED WITH WATTS FACTOR

INTRODUCTION AND OBJECTIVE: Detrusor underactivity (DU) increases with age. The International Continence Society definition of DU contains two different pathophysiological causes, namely weak detrusor contraction force and abnormally short detrusor contractions. Urodynamic studies have attempted to define DU, but no precise definition is widely accepted. Widely used measurements of bladder contractility are bladder contractility index (BCI) and the Watts factor (WF). Impaired bladder contraction represent not only decreased the peak of WF, but also poorly sustained contractions. From this point of view, the maximum height of the resulting curve (Wmax) and its pattern should be discussed separately. In the present study, we compare several contemporary urodynamic criteria and parameters calculated with WF. METHODS: Thirty five patients with pre and post radical prostatectomy were evaluated. The urodynamic parameters included the maximum flow rate (Qmax), postvoid residual volume (PVR), detrusor pressure at maximum flow (Pdet at Qmax), Wmax, W (Qmax), BCI (bladder contractility index; Pdet Qmax + 5Qmax), rV (Wmax), Line (W), W80-W20 were examined. (Each definition was shown in figure; see figure below) RESULTS: After radical prostatectomy, Qmax increased significantly (pre: 13.6 ± 6.7, post: 18.0 ± 7.0 ml/min; P < 0.01), whereas PdetQmax and PVR decreased significantly (50.6 ± 21.0 and 29.9 ± 16.9 cmH2O, 51.3 ± 61.9 and 15.1 ± 28.6 ml; P < 0.05). BCI, Wmax and W (Qmax) did not change significantly after radical prostatectomy (123.7 ± 36.0 and 114.0 ± 19.9, 11.5 ± 2.8 and 11.1 ± 3.0 W/m2, 8.8 ± 2.6 and 9.7 ± 2.9 W/m2), but rV(Wmax), Line(W), W80 – W20 decreased significantly (0.47 ± 0.3 and 0.20 ± 0.20, −0.0016 ± 0.01 and −0.010 ± 0.01 W/m2/mL, −0.4 ± 2.0 and −2.1 ± 2.6 W/m2; P < 0.05). Wmax and W (Qmax) represents the maximum power of bladder contraction at a particular point in time, whereas rV(Wmax) Line(W), W80 – W20 can be used to detect whole detrusor contraction pattern. The commonly used threshold values for the definition of DU are BCI < 100 or W max < 7 W/m2. In our current study, we couldn’t detect DU using these criteria. However, parameters calculated with WF detect subtle change or pattern of micturition. CONCLUSIONS: The parameters calculated with Watts factor provides some insight into the diagnosis of DU.Source of Funding: none

Prevalence of Lower Urinary Tract Symptoms in People with Multiple Sclerosis: A Systematic Review and Meta-analysis.

No published study, to our knowledge, has systematically reviewed the prevalence estimates of lower urinary tract symptoms (LUTSs) and LUTS types in the general multiple sclerosis (MS) population. Therefore, a systematic review and a meta-analysis were conducted to determine the totality of literature investigating the prevalence of LUTSs and LUTS types in the general MS population according to International Continence Society definitions. Various electronic databases were searched between January 4, 2018, and February 12, 2018. This review included observational studies involving adults (18 years or older) with a confirmed diagnosis of MS recruited from the general MS population using self-report and/or objective outcome measures for LUTSs. Twelve studies were included in the meta-analysis. The results showed that LUTSs were prevalent in people with MS, with a pooled prevalence of 68.41% using self-report and 63.95% using the objective measure of urodynamics. When considering LUTS types, urinary frequency was the predominant symptom, with a pooled prevalence estimate of 73.45%, followed by urgency assessed using self-report measures at 63.87%. Detrusor overactivity was found to be the most prevalent urodynamic symptom, with a pooled prevalence estimate of 42.9%, followed by detrusor sphincter dyssynergia at 35.44%. This systematic review revealed that LUTSs are highly prevalent in MS. There is a need for improvement in the conduct and reporting of prevalence studies of LUTSs in MS and for the use of validated self-report outcome measures to enable pooling of data in the future.

Association Among Lower Urinary Tract Symptoms, Erectile Function, and Sexual Satisfaction: Results from the Brazil LUTS Study.

IntroductionLower urinary tract symptoms (LUTS) affect ≥60% of adult men and are associated with erectile dysfunction (ED) and sexual dissatisfaction.AimThe aim of this study was to evaluate the relationship among male LUTS, ED, and sexual satisfaction.MethodsThis was a secondary analysis of the Brazil LUTS study, a cross-sectional, epidemiological survey conducted by telephone interview in 5 cities in Brazil. This analysis included men aged ≥40 years.Main Outcome MeasureLUTS were identified using International Continence Society definitions. LUTS severity was assessed using the International Prostate Symptom Score questionnaire. Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5) questionnaire and sexual satisfaction was rated on a 5-point scale.Results2,433 men participated in the study. Of 2,183 men reporting data on LUTS, 873 (40%) had LUTS “about half the time” or more. The prevalence of ED and sexual dissatisfaction was 14.4% and 7.8%, respectively. The proportion of men reporting ED and sexual dissatisfaction was higher among men with LUTS (24.6% and 13.8%, respectively) than men without LUTS (8.7% and 4.5%, respectively; P < .001). LUTS severity was negatively correlated with IIEF-5 scores (r = –0.199; P < .001); we estimated a 0.431-point decrease in IIEF-5 score per 3-point increase in International Prostate Symptom Score. Increased age and the presence of LUTS were associated with a greater chance of ED and sexual dissatisfaction; depression/anxiety and diabetes were associated with a greater chance of sexual dissatisfaction only. Among men with LUTS, urgency with fear of leaking, urgency urinary incontinence, and nocturnal enuresis were associated with a greater chance of ED, whereas slow stream and urgency urinary incontinence were associated with a greater chance of sexual dissatisfaction.ConclusionThese results demonstrate that the presence of LUTS is associated with an increased chance of ED and sexual dissatisfaction in Brazilian men and reinforce the importance of a comprehensive assessment of these conditions.Gomes CM, Averbeck MA, Koyama M, et al.

126 Urinary Incontinence: Prevalence, Clinical Characteristics and Impact on Quality of Life of Older People in Ireland

Abstract Background Urinary incontinence (UI) is one of the ‘giants’ of gerontological care, associated with early mortality, depression and falls in later life. It is often amenable to treatment, yet clinical experience suggests that older people with urinary incontinence often go undiagnosed and therefore untreated. The aim of this study therefore was to ascertain the prevalence of UI in a large population representative sample of Irish adults ≥50 years; to examine how often participants report UI to healthcare professionals; to profile factors associated with UI and its impact on quality of life (QOL). Methods This study was embedded within the Irish Longitudinal Study on Ageing. Participants were a population-representative sample of almost 7,000 Irish adults aged ≥50 years. UI was defined as any involuntary loss of urine from the bladder within the last 12 months, based on the International Continence Society Definition. QOL was measured using the Control, Autonomy, Self-realisation and Pleasure-19 Scale (CASP-19). Results Fifteen % (1,061/6,996) of participants had UI within the last 12 months; 9% (269/3,162) of males and 21% (792/3,834) of females. Almost half (486/1,061) of participants with UI had not reported it to a healthcare professional, with one fifth (240/1,061) reporting UI limited everyday activities. Logistic regression modelling demonstrated UI was associated with advancing age, female sex, alcohol excess, polypharmacy, chronic disease and depression. Linear regression models showed that UI was associated with significantly lower self-rated QOL, as measured by CASP-19 (β =-1.13 (95% CI: -1.69 - -0.57), p &lt;0.001). Conclusion UI affects 1 in 7 people aged ≥50 years. It is closely associated with other geriatric syndromes such as polypharmacy, depression and multimorbidity and impacts significantly on QOL. Despite this, almost half of those with UI do not report symptoms to a healthcare professional, highlighting the need for structured assessment of UI as part of comprehensive age-attuned care.

Functioning and disability of premenopausal women with urinary incontinence: An assessment by using the World Health Organization Disability Assessment Schedule-WHODAS 2.0.

To analyze the association between urinary incontinence and disability status in premenopausal women. The study included 120 premenopausal women recruited from six Basic Family Health Units to participate in this study. We assessed sociodemographic, gynecological, and obstetric data by using specific questions. The International Continence Society's definitions were applied to determine the presence and type of urinary incontinence, and the disability was assessed by using the 36-item version of the World Health Organization Disability Assessment Schedule (WHODAS) 2.0. The WHODAS scores showed that women with urinary incontinence had a worse disability in cognition (P = .023) and mobility (P = .020) domains, in addition to the total score (P = .23). Women with mixed urinary incontinence had a worse disability in mobility domain (P = .039) than those with stress or urgency incontinence. Qualitative analyses of disability showed a significant difference between women with and without urinary incontinence (P = .033), with higher percentages of incontinent women with moderate and severe disability. Women who reported urinary incontinence had 7.69 more points on the final score of WHODAS than those who did not report this outcome. Urinary incontinence in women of reproductive age is associated with disability and worse scores of WHODAS when we compare them to women without urine leakage. The results presented can be useful for designing and adapting strategies for comprehensive care of women with urinary incontinence and disability, and developing rehabilitation programs based on functioning.

Prevalence of overactive bladder in China, Taiwan and South Korea: Results from a cross-sectional, population-based study.

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

Prevalence analysis of urinary incontinence after radical prostatectomy and influential preoperative factors in a single institution

Aims: To assess prevalence of urinary incontinence (UI) after radical prostatectomy (RP) and to analyze which preoperative characteristics of the patients have influence on UI.Methods: Between 2002 and 2012, 746 consecutive patients underwent RP for clinically localized prostate cancer. We defined UI according to International Continence Society (ICS) definition: “the complaint of any involuntary leakage of urine” after 12 months of recovery, international consultation on incontinence questionnaire (ICIQ-SF) and pads/day was collected too. Clinical features and magnetic resonance imaging measurements were assessed. A multivariable logistic regression model predicting incontinence were built-in after adjust by cofounding factors and bootstrapping.Results: About 172 (23%) of the patients were classified as incontinent according to the ICS definition. The mean value of the ICIQ-SF was 10.87 (±4). 17.8% of patients use at least one pad/day, 11.9% use more than one pad/day. The preoperative factors independently influential in UI are: age [OR: 1.055; CI 95% (1.006–1.107), p = .028], urethral wall thickness [OR: 5.03; CI 95% (1.11–22.8), p = .036], history of transurethral resection of the prostate [OR: 6.13; CI 95% (1.86–20.18), p = .003] and membranous urethral length [OR: 0.173; CI 95% (0.046–0.64), p = .009]. The predictive accuracy of the model is 78.7% and the area under the curve (AUC) value 71.7%.Conclusions: Urinary incontinence after radical prostatectomy has different prevalence depending on the definition. Age, prior transurethral resection of the prostate (TURP), membranous urethral length (MUL) and urethral wall thickness (UWT) were risk factors.

Urethral Closure Pressure at Stress: A Predictive Measure for the Diagnosis and Severity of Urinary Incontinence in Women.

PurposeMaintaining urinary continence at stress requires a competent urethral sphincter and good suburethral support. Sphincter competence is estimated by measuring the maximal urethral closure pressure at rest. We aimed to study the value of a new urodynamic measure, the urethral closure pressure at stress (s-UCP), in the diagnosis and severity of female stress urinary incontinence (SUI).MethodsA total of 400 women without neurological disorders were included in this observational study. SUI was diagnosed using the International Continence Society definition, and severity was assessed using a validated French questionnaire, the Mesure du Handicap Urinaire. The perineal examination consisted of rating the strength of the levator ani muscle (0–5) and an assessment of bladder neck mobility using point Aa (cm). The urodynamic parameters were maximal urethral closure pressure at rest, s-UCP, Valsalva leak point pressure (cm H2O), and pressure transmission ratio (%).ResultsOf the women, 358 (89.5%) were diagnosed with SUI. The risk of SUI significantly increased as s-UCP decreased (odds ratio [OR], 0.92; 95% confidence interval, 0.88–0.98). The discriminative value of the measure was good for the diagnosis of SUI (area under curve>0.80). s-UCP values less than or equal to 20 cm H2O had a sensitivity of 73.1% and a specificity of 93.0% for predicting SUI. The association between s-UCP and SUI severity was also significant.Conclusionss-UCP is the most discriminative measure that has been identified for the diagnosis of SUI. It is strongly inversely correlated with the severity of SUI. It appears to be a specific SUI biomarker reflecting both urethral sphincter competence and urethral support.

The Prevalence of Nocturia and Nocturnal Polyuria: Can New Cutoff Values Be Suggested According to Age and Sex?

PurposeThe aims of this study were to assess the prevalence of nocturia and nocturnal polyuria (NP) and to define new cutoff values according to age and sex for both conditions.MethodsData from a population-based prevalence survey conducted among a random sample of 2,128 adults were analyzed in this study. Participants were requested to fill out a questionnaire including the International Continence Society (ICS) definitions of lower urinary tract symptoms and the International Consultation on Incontinence Questionnaire - Short Form. Additionally, a 1-day bladder diary was given to each individual. The participants were divided into 5 age groups. The prevalence of nocturia was calculated based on definitions of nocturia as ≥1 voiding episodes, ≥2 episodes, and ≥3 episodes. NP was evaluated according to the ICS definition. The mean±standard errors and 95th percentile values were calculated in each group as new cutoff values for NP.ResultsThe prevalence of nocturia was estimated as 28.4%, 17.6%, and 8.9% for ≥1, ≥2, and ≥3 voiding episodes each night, respectively. When nocturia was defined as 2 or more voiding episodes at night, the prevalence decreased significantly. The mean NP index was 29.4%±15.0% in men and 23.1%±11.8% in women. For the age groups of <50 years, 50–59 years, and ≥60 years, the new cutoff values for the diagnosis of NP were calculated as 48%, 69%, and 59% for men and 41%, 50%, and 42% for women, respectively.ConclusionsWe found that the definition of nocturia was still controversial and that waking up once for voiding might be within the normal spectrum of behavior. The definition of NP should be modified, and new cutoff values should be defined using the data presented in our study and in other forthcoming studies.

Ten-Year Prevalence and Incidence of Urinary Incontinence in Older Women: A Longitudinal Analysis of the Health and Retirement Study.

To measure the incidence of urinary incontinence (UI) over 10years in older women who did not report UI at baseline in 1998, to estimate the prevalence of female UI according to severity and type, and to explore potential risk factors for development of UI. Secondary analysis of a prospective cohort. Health and Retirement Study. Women participating in the Health and Retirement Study between 1998 and 2008 who did not have UI at baseline (1998). UI was defined as an answer of "yes" to the question, "During the last 12months, have you lost any amount of urine beyond your control?" UI was characterized according to severity (according to the Sandvik Severity Index) and type (according to International Continence Society definitions) at each biennial follow-up between 1998 and 2008. In 1998, 5,552 women aged 51 to 74 reported no UI. The cumulative incidence of UI in older women was 37.2% (95% confidence interval (CI)=36.0-38.5%). The most common incontinence type at the first report of leakage was mixed UI (49.1%, 95% CI=46.5-51.7%), and women commonly reported their symptoms at first leakage as moderate to severe (46.4%, 95% CI=43.8-49.0%). Development of UI in older women was common and tended to result in mixed type and moderate to severe symptoms.

Preoperative Prolapse Stage as Predictor of Failure of Sacrocolpopexy.

Our aim was to determine if there was a correlation between the preoperative prolapse stage and postoperative recurrence of prolapse 1 year after sacrocolpopexy. Our null hypothesis is that the preoperative stage of prolapse does not increase the risk of recurrence. This is a multicenter cohort study from 3 centers. We included subjects who underwent robotic-assisted sacrocolpopexy and completed a standardized 1-year follow-up from 2009-2014. All subjects underwent a complete preoperative evaluation and completed 12 months of follow-up with the pelvic organ prolapse quantification examination. We compared those subjects who met the definition of recurrence with those who did not, analyzing the following covariates: stage of prolapse using International Continence Society (ICS) definitions, individual pelvic organ prolapse quantification points, age, body mass index, race, exogenous estrogen use, menopause, smoking, vaginal parity, cesarean section, and performance of concomitant procedures. We defined recurrence as any prolapse beyond the hymen. We had 125 women from 3 centers who met our criteria, with 23.2% of them having recurrence at 1 year. We found that recurrence increased as the preoperative ICS stage of prolapse increased (P = <0.001 in the univariate model). In the multivariate model, using logistic regression, we found that the risk of recurrence of pelvic organ prolapse increased as the presurgery clinical stage increased with an odds ratio of 3.8 (95% confidence interval, 1.5-9) when controlling for age, menopausal status, and genital hiatus (P = 0.004). Much like a higher stage of disease in oncology, we found that increasing stage of prolapse preoperatively increased the risk of recurrence at 1 year after sacrocolpopexy.
