Prevalence and associated factors in community-dwelling subjects - a population-based study

SUMMARY OBJECTIVES To assess the prevalence of nocturia and identify factors associated with it in a community-dwelling population. METHODS A cross-sectional study was conducted in subjects aged 45 years or more and registered with a Family Doctor Program. Information was collected about nocturia, other urinary symptoms, physical examination, co-morbidities, demographics, socio-economic, and lifestyle factors. Multiple logistics regression models were developed to analyze associated factors for nocturia according to gender and the number of nocturnal micturitions(≥1 and ≥2). RESULTS Out of the 661 individuals included in the study, 62.3% were women. Among the women, the prevalence rates for nocturia ≥1 time and ≥2 times were, respectively, 68.4% and 49%, whereas, among the men, they were 64.3% and 43.8%. Among the women, nocturia ≥1 time was associated with brown skin, a higher BMI, lower schooling, and calcium channel blockers(CCB) use, while nocturia ≥2 times showed association with higher BMI, lower schooling, obstructive sleep apnea (OSA), and the use of CCB. Among the men, nocturia ≥1 time was associated positively with age, alcohol intake, and OSA, and negatively with angiotensin receptor blockers and beta-blockers use. Besides, nocturia ≥2 times was associated with age, not having health insurance, and OSA. CONCLUSIONS Nocturia is a condition highly prevalent in the studied population. For the female subjects, a higher BMI, lower schooling, and the use of CCB were associated with nocturia regardless of the definition used, whereas, among the men, that same association was found with age, not having health insurance, and OSA.

RESUMO OBJETIVOS Estimar a prevalência de noctúria e identificar fatores demográficos, socioeconômicos, clínicos e de estilo de vida associados ao sintoma em uma população comunitária. MÉTODO Estudo transversal em indivíduos com 45 anos ou mais. Foram obtidas informações demográficas, socioeconômicas, sobre noctúria, outros sintomas urinários, exame físico, comorbidades e estilo de vida. As análises foram feitas separadamente de acordo com o gênero e com o número de micções noturnas (≥1 vez e ≥2 vezes). RESULTADOS Dentre os 661 indivíduos incluídos, 62,3% eram mulheres. Entre elas, a prevalência de noctúria ≥1 vez e ≥2 vezes foi, respectivamente, de 68,4% e 49%, enquanto entre os homens foi de 64,3% e 43,8%. Entre as mulheres, a noctúria ≥1 mostrou associação com cor da pele parda, maior IMC, baixa escolaridade e uso de bloqueadores dos canais de cálcio (BCC), enquanto noctúria ≥2 vezes mostrou associação com maior IMC, baixa escolaridade, apneia obstrutiva do sono (AOS) e uso de BCC. Entre os homens, a noctúria ≥1 vez esteve associada positivamente com idade, ingestão de álcool e AOS, e negativamente com uso de bloqueadores dos receptores da angiotensina e de beta-bloqueadores. Além disso, noctúria ≥2 vezes associou-se a idade, não ter plano de saúde e AOS. CONCLUSÕES A noctúria é uma condição altamente prevalente na população estudada. Para as mulheres, IMC elevado, baixa escolaridade e uso de BCC estiveram associados com noctúria independente da definição, enquanto que, para os homens, a mesma associação foi identificada com idade, não ter plano de saúde e AOS.

Effect of Nocturnal Hypoxia on Nocturia in Patients With Obstructive Sleep Apnea / 대한배뇨장애요실금학회지

PURPOSE: To identify the association between nocturia and obstructive sleep apnea (OSA), we compared results of polysomnography (PSG) with the presence or absence of nocturia in patients with suspected OSA. METHODS: Patients underwent PSG for suspected OSA. The International Prostate Symptom Score and quality of life (IPSS/QoL) questionnaire was evaluated to assess voiding symptoms that may affect sleep quality. The results of PSG were compared between patient groups with or without nocturia. RESULTS: In logistic regression analysis, age (odds ratio [OR], 1.052; P=0.004), diabetes mellitus (OR, 6.675; P<0.001), mean O₂ saturation (OR, 0.650; P=0.017), oxygen desaturation index (ODI) 3 (OR, 1.193; P=0.010), and ODI4 (OR, 1.136; P=0.014) affected nocturia independently among the OSA-suspected patients. CONCLUSIONS: Hypoxia caused by OSA affects the incidence of nocturia. Less desaturated OSA patients with nocturia may require more urological evaluation and treatment for nocturia even after the correction of OSA.

The Association Between Obesity and the Nocturia in the U.S. Population / 대한배뇨장애요실금학회지

PURPOSE: We aimed to investigate the association of obesity with nocturia using a nationally representative sample of adults from the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2012. METHODS: A total of 14,135 participants were included in this study. We performed a multivariate logistic regression analysis to find the odds ratio (OR) of obesity for nocturia. Furthermore, the OR of BMI for nocturia was analyzed using restricted cubic splines (RCS) with five knots. We conducted subgroup analysis according to age, sex, hypertension, and diabetes mellitus (DM) and further analysis with 1:1 matching data with propensity score. RESULTS: The participants who had body mass index (BMI) above 30 kg/m² had a significantly higher OR for nocturia (OR, 1.39; 95% CI, 1.28–1.50) than those without obesity. RCS showed a dose-dependent relationship between BMI and OR for nocturia. Subgroup analysis by age, sex, hypertension, and DM showed similar results. Further analysis with 1:1 matching data showed a significant association of obesity with the prevalence of nocturia (OR, 1.25; 95% CI, 1.10–1.41). CONCLUSIONS: This study reported that obesity was significant association with the prevalence of nocturia with dose-dependent manner, regardless of age, sex, hypertension, and DM after taking major confounding factors into account.

Influence of Circadian Disruption Associated With Artificial Light at Night on Micturition Patterns in Shift Workers / 대한배뇨장애요실금학회지

Shift workers often experience problems associated with circadian disruption associated with artificial light at night and nocturia is commonly noted in night-shift workers. Nocturia associated with circadian disruption is due to increased urine production of the kidney and decreased storage function of the bladder. A recent discovery of peripheral clock genes in the bladder and their role in contractile property of the bladder support that micturition is closely related to the circadian rhythm. Moreover, there are clinical studies showed that shift workers more often experienced nocturia due to circadian disruption. However, comparing with other health problems, concerns on nocturia and voiding dysfunction associated with circadian disruption are insufficient. Therefore, further studies about voiding dysfunction associated with the circadian disruption in shift workers are necessary.

Do Failure of Posterior Tibial Nerve Stimulation Precludes to Use Sacral Neuromodulation in Patient With Overactive Bladder? / 대한배뇨장애요실금학회지

PURPOSE: To evaluate the outcomes of sacral neuromodulation (SNM) after failure of transcutaneous posterior tibial nerve stimulation (TPTNS) in patients with overactive bladder (OAB).METHODS: A retrospective study was conducted in 3 university hospitals and included all patients with OAB and treated with SNM after TPTNS had been tried between October 2008 and May 2018. The primary endpoint was the proportion of definitive SNM device implantation in patients with 50% objective and/or subjective improvement after a test period (stage 1). The secondary outcomes of interest were changes of the number of diurnal voids and nocturia episodes per 24 hours between the end of TPTNS and the end of stage 1.RESULTS: Overall, 28 of the 43 patients included achieved at least 50% objective and/or subjective improvement during stage 1 and underwent an Interstim II implantation (65.1%). The mean daytime frequency decreased significantly from 10.3/day at the end of TPTNS to 7.8 diurnal voids/day at the end of SNM stage 1 (P=0.01). The mean number of nocturia episodes decreased from 2.5/night at the end of TPTNS to 2.1/night at the end of stage 1, but this did not reach statistical significance (P=0.18). There was no other parameter significantly associated with response to SNMCONCLUSIONS: SNM might improve OAB symptoms in most patients who experienced no or poor efficacy with TPTNS. History of failed TPTNS should not preclude the use of SNM in OAB patients.

A Prospective, Multicenter, Open-Label Study of Dose Escalation Therapy in Male Patients With Nocturia Refractory to 0.2-mg Tamsulosin Monotherapy / 대한배뇨장애요실금학회지

PURPOSE: To investigate the efficacy and safety of 0.4 mg of tamsulosin in patients with nocturia not responding to 0.2 mg.METHODS: Patients with intractable nocturia after treatment with 0.2 mg of tamsulosin for>1 month were included in a multicenter, prospective, observational, single-arm study. Patients were prescribed 0.4 mg of tamsulosin and followed up for 2 months to assess nocturnal voiding and nocturia-related bother. Changes in the mean number of nocturnal voids, the proportion of 50% responders, 3-day frequency-volume chart parameters, and questionnaire scores were assessed.RESULTS: Sixty-two patients were prescribed 0.2 mg of tamsulosin, of whom 56 were prescribed 0.4 mg of tamsulosin. Ten patients dropped out. A single case of orthostatic hypotension was reported. The mean age was 68 years. After 1 and 2 months of taking 0.4 mg of tamsulosin, 23.9% and 22.7% of patients demonstrated a>50% reduction of nocturia, and 16.1% and 19.4% of patients rated the treatment as “very effective,” respectively. Dose escalation to 0.4 mg of tamsulosin, compared to 0.2 mg, did not show an additional effect on reducing nocturnal urine volume. Multivariate logistic regression analysis showed that lower serum sodium levels (odds ratio [OR], 0.41, P=0.037) and the presence of urge incontinence (OR, 7.08, P=0.036) were predictors of a significant improvement of nocturia in response to 0.4 mg of tamsulosin.CONCLUSIONS: Dose escalation may yield a significant improvement of nocturia in>20% of patients, and may be especially helpful in patients with lower sodium levels and urge incontinence.

Seasonal Variation of Overactive Bladder Symptoms in Female Patients / 대한배뇨장애요실금학회지

PURPOSE: To evaluate seasonal variations of overactive bladder (OAB) symptoms in women who visited hospital clinics.METHODS: Medical records of female patients treated for OAB symptoms from January 2011 to December 2017 were retrospectively reviewed. Patients with pyuria at the first visit, those who did not complete the questionnaire, and those with <3 overactive bladder symptom scores (OABSS) were excluded. Uroflowmetric parameters, 3-day micturition diary, and OABSS were analyzed.RESULTS: A total of 582 patients with OAB symptoms who visited the hospital were enrolled in this study. Patients were grouped into 1 of the 3 season groups (cold, intermediate, and hot) depending on the average temperature of the month that the patient first visited the urologic department outpatient clinic. The total OABSS was significantly different between the 3 season groups (cold [7.25±3.20] vs. intermediate [6.24±3.40] vs. hot [5.51±3.20], P=0.001). The proportion of patients who had moderate OAB symptoms (6≤OABSS) was higher in the cold season group (56.2%) than in the other season groups (intermediate, 42.1%; hot, 31.8%; P=0.002). Differences in the number of micturitions (12.12±4.56 vs. 10.95±4.39, P=0.021) and number of urgent urinary incontinence episodes (2.06±0.94 vs. 2.48±0.87, P=0.001) between the cold and hot season groups were also significant. However, differences in the nocturia episode, total daytime voided volume, and mean voided volume between season groups were not significant.CONCLUSIONS: Different urinary symptoms and uroflowmetric parameters were correlated with seasonal variation. OAB symptoms might be worse in cold season than in other seasons.

Overactive bladder syndrome and bladder wall thickness in patients with obstructive sleep apnea syndrome

ABSTRACT Objective The main objective of the present study was to evaluate the presence of overactive bladder (OAB) syndrome, nocturia, urgency, and urge incontinence in patients with obstructive sleep apnea syndrome (OSAS), and measure bladder wall thickness (BWT) in these patients. Materials and Methods The patient group was composed of 38 patients with OSAS. The control group was composed of 15 healthy individuals. All patients were evaluated using the Epworth Sleepiness Scale (ESS) and Overactive Bladder Symptom Score (OABSS). The bladder wall thickness was measured by transabdominal ultrasound (US). The presence of nocturia, urinary urgency, and urge incontinence were also evaluated. Results The mean OABSS was significantly higher in the patient group compared with the control group (p=0.048). The minimum oxygen saturation (Min.SO2) of patients with urgency was found to be significantly lower (p=0.014). The time spent below 90% of oxygen saturation (SO2) was significantly longer in patients with urinary urgency (p=0.009). There was no difference in BWT measurements between the patient group and the control group. There was a significant relationship between BWT values and OABSS in patients with OSAS (p=0.002). Conclusion The results of the present study suggest that OSAS is associated with OAB syndrome. As a key symptom of OAB, urgency correlates with hypoxia in cases with OSAS. Although the present study did not observe any difference in BWT measurements between the patients and the control group, there was a correlation between BWT measurements and OABSS in patients with OSAS.

Is It Worth Treating Non-Bothering Nocturia? Results of a Multicenter Prospective Observational Study

PURPOSE: The purpose of this study was to evaluate the efficacy of treatment in patients with non-bothering nocturia. MATERIALS AND METHODS: In this prospective multicenter study, patients who visited hospitals for treatment of voiding symptoms were enrolled. Inclusion criteria were: 1) men >45 years, and 2) nocturia ≥2 confirmed by a three-day voiding diary. Subjects were divided into non-bothering and bothering groups based on International Consultation on Incontinence Questionnaire Nocturia (ICIQ-N) question 2b. Changes in voiding symptoms, frequency of nocturia, and bothersomeness were evaluated with international prostate symptom score (IPSS), ICIQ-N, and three-day voiding diary at 4 and 12 weeks after treatment. RESULTS: A total of 48 patients in the non-bothering nocturia group and 50 patients in the bothering nocturia group who completed the 12-week treatment were analyzed. The total IPSS was decreased by 5.8 in the non-bothering group and 5.2 in the bothering group. There was no significant difference in decrease of IPSS between the two groups. Both groups showed significant reduction in discomfort of nocturia. The ICIQ-N 2b score decreased from 3.9 to 2.7 (p=0.01) in the non-bothering group and from 6.9 to 4.6 (p=0.02) in the bothering group. The number of nocturia episodes was significantly decreased in both groups. CONCLUSIONS: Regardless of discomfort associated with nocturia, both groups showed significant improvement in nocturia-related discomfort and voiding symptoms. These results suggest that patients with nocturia who were unaware of its discomfort benefited from treatment.

Specificity of Lower Urinary Tract Symptoms in Neuromyelitis Optica in Comparison With Multiple Sclerosis Patients / 대한배뇨장애요실금학회지

PURPOSE: The aim of this study was to describe lower urinary tract symptoms in neuromyelitis optica (NMO), and to compare these data with urinary disorders observed in multiple sclerosis (MS) patients. METHODS: Retrospective study of data collected from January 1997 to July 2017 using the database from a Neuro-Urology Department of a university hospital. NMO and MS patients were matched for sex, age, and Expanded Disability Status Scale (EDSS) RESULTS: Twenty-six patients with NMO were included and compared with 33 MS patients. Mean age was 41.6 years (standard deviation [SD], 14,8), mostly female patients (24 vs. 2 males). Mean EDSS was 4.6 (SD, 1.8) in the 2 groups. In NMO group, 57% of the patients (n=15) had overactive bladder with urgency and urge incontinence and 38.5% (n=10) of them had nocturia. Voiding symptoms was observed in 69.2% of the patients (n=18); 42.3% of NMO patients performed self-intermittent catheterization versus 12.1% in MS patients (P=0.012). Low bladder compliance and severe urinary tract infections (pyelonephritis) were more frequent in NMO than in MS patients (respectively 15% vs. 0%, P=0.016 and 42% vs. 12%, P=0.024). CONCLUSIONS: Lower urinary tract symptoms, especially overactive bladder and urinary retention, are frequent in NMO. Low bladder compliance, serious urinary infections, and high prevalence of urinary retention requiring self-intermittent catheterization are the main symptoms significantly more frequent than in MS.

Factors Influencing Lower Urinary Tract Symptoms in Advanced Cancer Patients With Chemotherapy-Induced Peripheral Neuropathy / 대한배뇨장애요실금학회지

PURPOSE: This study aimed to investigate the severity of lower urinary tract symptoms (LUTS) and to identify factors that influenced LUTS in advanced cancer patients with chemotherapy-induced peripheral neuropathy (CIPN). METHODS: This cross-sectional study included a total of 158 advanced cancer patients with CIPN. A structured questionnaire including the International Prostate Symptom Score and the Functional Assessment of Cancer Therapy/Gynecology Oncology Group/Neurotoxicity scale was used. Data were analyzed using the Pearson correlation coefficient and multiple regression analysis. RESULTS: Nocturia was the most prevalent LUTS. A positive relationship was found between CIPN symptoms and LUTS. The duration of cancer diagnosis and the severity of CIPN were key factors that influenced LUTS. CONCLUSIONS: The severity of CIPN symptoms was the most important predictor of LUTS. Nurses’ care for advanced cancer patients should incorporate a comprehensive health assessment, which includes a history of treatment and physical neuropathic symptoms, for any patient complaining of CIPN symptoms.

Sex Differences in Lower Urinary Tract Symptoms in Older Korean Adults Living in Rural Areas: Prevalence, Quality of Life, and Associated Factors / 대한배뇨장애요실금학회지

PURPOSE: Urinary incontinence (UI) is associated with nursing home admission, functional decline, and risk of death among community-dwelling older adults. Little information, however, is available on sex differences in lower urinary tract symptoms (LUTS) in older Korean adults exclusively living in rural areas. This study examined sex-related differences in LUTS, factors associated with UI in older adults living in rural areas, and health-related quality of life (HRQoL) in incontinent older adults. METHODS: This was a cross-sectional study in which face-to-face interviews were conducted at 15 rural community-health centres. A total of 323 older adults aged ≥65 years from rural areas of Korea participated. LUTS prevalence was evaluated and HRQoL was measured using the King’s Health Questionnaire. The chi-square test and t -test were used to examine sex differences in characteristics, LUTS, and HRQoL. Multivariable logistic regression was used to identify risk factors associated with UI. RESULTS: Nocturia was the most prevalent symptom, affecting 87% of men and 86% of women. Women (53%) had significantly more UI of any kind than did men (35%) (P=0.007). Urgency UI was the most frequent type of UI in men, whereas stress UI was the most frequent in women. Regarding HRQoL, men had significantly higher scores in the domains of sleep/energy disturbances (P=0.032) than did women, and women reported greater effects from the severity of incontinence (P=0.001) than did men. Arthritis was the only factor associated with UI in men (odds ratio [OR], 6.88; 95% confidence interval [CI], 1.46–32.36). However, women with diabetes mellitus were less likely to have UI than those without (OR, 0.43; 95% CI, 0.23–0.82). CONCLUSIONS: LUTS were found to be highly prevalent in community-dwelling older Korean adults in rural areas. Interventions to improve sleep and to reduce UI severity are needed for incontinent men and women, respectively.

Clinical Efficacy of Solifenacin in the Management of Diabetes Mellitus-Associated Versus Idiopathic Overactive Bladder Symptoms: A Multicenter Prospective Study / 대한배뇨장애요실금학회지

PURPOSE: To compare the clinical efficacy of anticholinergics for managing diabetes mellitus-associated overactive bladder (DM OAB) versus idiopathic overactive bladder (OAB) in Korean women. METHODS: We conducted a multicenter, prospective, parallel-group, open-label, 12-week study. Women (20–65 years old) with OAB symptoms for over 3 months were assigned to the DM OAB and idiopathic OAB groups. Changes in the Overactive Bladder Symptom Score (OABSS), urgency, urinary urgency incontinence, nocturia, daytime frequency according to a voiding diary, uroflowmetry, and postvoid residual urine volume (PVR) at the first visit (V1), week 4 (V2), and week 12 (V3) were compared. RESULTS: No significant difference was found between the baseline patient characteristics of the DM OAB and idiopathic OAB groups. Treatment with solifenacin was associated with improvements in urgency, urinary urgency incontinence, nocturia, frequency according to a voiding diary, and the total OABSS between V1 and V2 and between V1 and V3. Moreover, a significant improvement in urgency and urge incontinence was found between V2 and V3 in the DM OAB group. However, no significant changes were found in any other parameters. There were no significant differences between the DM OAB group and the idiopathic OAB group except for urgency and urge incontinence at V2 (3.71 vs. 2.28 and 0.47 vs. 0.32, respectively). CONCLUSIONS: The patients who received solifenacin demonstrated improved urgency, urinary urgency incontinence, nocturia, frequency according to a voiding diary, and total OABSS. Management with solifenacin was equally effective for both DM-related OAB and idiopathic OAB.

Pelvic floor muscle training for overactive bladder symptoms - A prospective study / Treinamento dos músculos do assoalho pélvico nos sintomas da bexiga hiperativa - Um estudo prospectivo

Summary Introduction: Pelvic floor muscle training (PFMT) involves the contraction of the puborectal, anal sphincter and external urethral muscles, inhibiting the detrusor contraction, what justify its use in the treatment of overactive bladder (OAB) symptoms. Objective: To verify the effects of isolated PFMT on the symptoms of OAB. Method: Prospective clinical trial with 27 women with mixed urinary incontinence (MUI), with predominance of OAB symptoms and loss ≥ 2 g in the pad test. It was evaluated: pelvic floor muscles (PFMs) function (digital palpation and manometry); urinary symptoms (nocturia, frequency and urinary loss); degree of discomfort of OAB symptoms; and quality of life (Incontinence Quality-of-Life Questionnaire [I-QoL]). The PFMT program consisted of 24 outpatient sessions (2x/week + home PFMT). The Mann-Whitney and Wilcoxon tests (with a significance level of 5%) were used to analyse the data. Results: There was a significant improvement of the urinary symptoms to the pad test (5.8±9.7, p<0.001), urinary loss (0.7±1.1, p=0.005) and nocturia (0.8±0.9, p=0.011). Reduction in the degree of discomfort of urinary symptoms was observed according to OAB-V8 questionnaire (10.0±7.7, p=0.001). There were also significant results in PFMs function: Oxford (3.6±0.9, p=0.001), endurance (5.2±1.8, p<0.001), fast (8.9±1.5, p<0.001) and manometry (26.6±15.8, p=0.003). In addition, quality of life had a significant improvement in the three domains evaluated by I-QoL. Conclusion: The PFMT without any additional guidelines improves the symptomatology, the function of PFMs and the quality of life of women with OAB symptoms.

Resumo Introdução: O treinamento dos músculos do assoalho pélvico (TMAP) envolve a contração dos músculos puborretal, esfíncteres anal e uretral externo, inibindo a contração do detrusor, o que justifica sua utilização no tratamento dos sintomas da bexiga hiperativa (BH). Objetivo: Verificar os efeitos do TMAP isolado sobre a sintomatologia da BH. Método: Ensaio clínico prospectivo com 27 mulheres com incontinência urinária mista (IUM), com predomínio de sintomas de BH e perda ≥ 2 g no pad test. Avaliaram-se: função dos músculos do assoalho pélvico (MAP) (palpação digital e manometria); sintomas urinários (noctúria, frequência e perda urinária); grau de incômodo dos sintomas de BH (Overactive Bladder Questionnaire [OAB-V8]); e qualidade de vida (Incontinence Quality-of-Life Questionnaire [I-QoL]). O programa de TMAP consistiu em 24 sessões ambulatoriais (2x/semana + TMAP domiciliar). Os testes de Mann-Whitney e Wilcoxon (com nível de significância de 5%) foram utilizados para analisar os dados. Resultados: Observou-se melhora significativa dos sintomas urinários ao pad test (5,8±9,7; p<0,001); ao diário miccional (perda urinária [0,7±1,1; p=0,005] e noctúria [0,8±0,9; p=0,011]). Foram observados redução do grau de incômodo dos sintomas urinários conforme questionário OAB-V8 (10,0±7,7; p=0,001) e significativos resultados na função dos MAP: Oxford (3,6±0,9; p=0,001), Endurance (5,2±1,8; p<0,001), Fast (8,9±1,5; p<0,001) e manometria (26,6±15,8; p=0,003). No mais, a qualidade de vida teve significativa melhora nos três domínios avaliados pelo I-QoL. Conclusão: O TMAP sem quaisquer orientações adicionais melhora a sintomatologia, a função dos MAP e a qualidade de vida de mulheres com sintomas de BH.

Characteristics of Mixed Urinary Incontinence and Stress Urinary Incontinence: Relationship between Lower Urinary Tract Symptoms and Urodynamic Parameters

PURPOSE: The purpose of this study was to analyze the relationship between lower urinary tract symptoms and urodynamic parameters to investigate the characteristics of mixed urinary incontinence (MUI) and stress urinary incontinence (SUI). METHODS: The subjects were 318 women with MUI and 128 women with SUI. Data were collected retrospectively from electronic medical records including Bristol Female Lower Urinary Tract Symptoms-Scored Form (BFLUTS-SF), Incontinence Quality of Life Instrument (I-QOL), voiding diaries, and urodynamic parameters. RESULTS: Compared with the SUI group, the MUI group was older and showed lower I-QOL and more severe urinary tract symptoms. The MUI group had more urinary frequency, more nocturia, and a higher urgency score than the SUI group. In the correlation analysis, the greatest difference between the two groups was that urgency was associated with Qmax, maximal cystometric capacity, and detrusor condition over activity only in the MUI group (r=−.175, p=.004; r=−.281, p<.001; r=.232, p<.001, respectively). CONCLUSION: As a result of this study, we propose that a customized management program that emphasizes the control of pelvic floor for the MUI group, and one that effectively strengthens the weak pelvic floor for the SUI group.

Seasonal Changes in Lower Urinary Tract Symptoms in Japanese Men With Benign Prostatic Hyperplasia Treated With α₁-Blockers / 대한배뇨장애요실금학회지

PURPOSE: To investigate whether seasonal changes occurred in lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH). METHODS: Patients aged 50 years and older with BPH treated with α1-blockers were enrolled. The International Prostate Symptom Score (IPSS), quality of life (QoL) score, maximum and average flow rate, voided volume, and postvoid residual volume were measured in summer and winter. RESULTS: A total of 164 patients were enrolled. The total IPSS and QoL index did not show a significant difference between the 2 seasons. When the IPSS was divided into storage symptoms and voiding symptoms, storage symptoms in winter were substantially but nonsignificantly higher than those in summer (P=0.056). Of the 7 individual symptoms in the IPSS, a significant seasonal difference was observed only for nocturia, with a higher score in winter. Moreover, none of the uroflowmetric parameters showed a seasonal change. Voided volume had significant correlations with each symptom (urgency and nocturia) and overall subjective scores (storage, total IPSS, and QoL) exclusively in summer, while this correlation remained only for nocturia in winter. CONCLUSIONS: As it has generally been assumed that LUTS deteriorate in winter, the present study corroborated that the severity of storage symptoms was higher in winter than in summer, even in patients treated with α₁-blockers. In contrast, a seasonal difference was not observed in the uroflowmetric parameters, which may be partly due to the loss of the correlation between subjective and objective measurements of storage symptoms in winter.

Is There Any Difference Between Depression and Anxiety in Overactive Bladder According to Sex? A Systematic Review and Meta-Analysis / 대한배뇨장애요실금학회지

PURPOSE: Overactive bladder (OAB) is characterized by urinary urgency with or without urge incontinence, accompanied by frequency and nocturia. It affects individuals of all ages and can predispose affected individuals to depression and anxiety. However, few studies have been conducted on this topic. The objective of this study was to perform a systematic review and meta-analysis assessing the symptoms of depression, anxiety, and OAB using validated instruments. METHODS: The search for articles was based on the following descriptors: overactive bladder, depression, and anxiety (“Urinary bladder, Overactive AND Depression and Anxiety”) OR (“Urinary bladder, Overactive AND Depression” OR “Urinary bladder, Overactive AND Anxiety”). The databases searched included PubMed, MEDLINE, and SciELO. RESULTS: Initially, 111 articles were identified, but only 11 articles, containing 11,784 participants with depression and 10,436 with anxiety, specifically addressed depression or anxiety and were included in this systematic review. Ten articles incorporated a quantitative analysis, with cohort, series, population-based, and cross-sectional designs. One qualitative study was also included. Three articles were included in the meta-analysis, resulting in a total of 7,468 participants in whom depression was evaluated and 8,030 participants in whom anxiety was analyzed. Depression and anxiety were positively correlated with OAB. Men with OAB were considerably more likely than women to have anxiety (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.40–1.73) but there was no sex-related difference in depression (OR, 0.96; 95% CI, 0.77–1.21). CONCLUSIONS: This study showed a positive correlation between OAB and anxiety and depression. Men were considerably more likely than women to have anxiety related to OAB, but depression levels in OAB patients were not sex-related. This review highlights the need to investigate depression and anxiety in patients with OAB.
