ABSTRACT
INTRODUCTION AND HYPOTHESIS: Electrical nerve stimulation is a widely used treatment for overactive bladder but there is no consensus regarding the best placement of electrodes or protocols. We hypothesised that some non-implanted neurostimulation protocols would be more effective compared to others for treating urinary symptoms and improving quality of life among adults diagnosed with non-neurogenic overactive bladder. METHODS: A systematic review and meta-analyses of randomized clinical trials were performed in five electronic databases: PubMed/MEDLINE, Lilacs, CINAHL, Web of Science, and PEDro. The main outcome was urinary symptoms-frequency, nocturia, and urgency-and the secondary outcome quality of life. Some protocol characteristics were extracted, e.g., frequency, pulse width, intensity, intervention time, and electrode placement. RESULTS: Nine randomized controlled trials were included. Tibial neurostimulation showed better results than sacral neurostimulation for urge incontinence (mean difference = 1.25 episodes, 95% CI, 0.12-2.38, n = 73). On the pooled analysis, the different neurostimulation protocols-intravaginal, percutaneous tibial, and transcutaneous tibial nerve stimulation-demonstrated similar results for urinary frequency, nocturia, and urgency as well as quality of life. In general, effect sizes from meta-analyses were low to moderate. The best reported parameters for percutaneous tibial nerve stimulation were 20-Hz frequency and 200-µs width, once a week. CONCLUSIONS: There was evidence that tibial neurostimulation is more effective than sacral neurostimulation for urge incontinence symptoms among patients with non-neurogenic overactive bladder. Overall, there was no superiority of an electrical nerve stimulation electrode placement and protocol over others considering urinary symptoms and quality of life. Further studies with three-arm trials are necessary. This study was registered at PROSPERO: CRD4201810071.

Abstract Objective: to identify risk factors related to overactive bladder syndrome. Method: a cross-sectional study was performed with elderly women (>60 years) from the community of Ceilândia, in the Distrito Federal, Brazil, with or without symptoms of OBS, who were evaluated through interviews and questionnaires. The clinical and sociodemographic variables analyzed were: age; body mass index (BMI); parity, schooling, previous abdominal and urogynecologic surgeries, physical activity, smoking, constipation, systemic arterial hypertension (SAH), diabetes mellitus; depression and anxiety. The questionnaires applied were the Overactive Bladder Awareness Tool (OAB-V8), the Geriatric Depression Scale and the Beck Anxiety Scale. Data were analyzed descriptively. Binary logistic regression was used to evaluate the significant associations between the independent variables and the outcome of interest. Risk ratios were calculated for each independent variable with 95% confidence intervals. Result: A total of 372 volunteers were recruited, 292 of whom were eligible. Of these, 172 were allocated to the case group (58.9%) and 120 (41.1%) were control subjects. The two groups were homogeneous between one another. There was a high prevalence of OBS in the study population and significant differences for the variables presence of SAH, abdominal surgery and pelvic surgery, with the case group presenting a higher frequency of these events. In multivariate analysis, it was observed that an active sexual life reduces the chance of having OBS by 70.8%, while urogynecologic surgeries increase this risk 3.098 times. Conclusion: In univariate logistic regression analysis, BMI, SAH, a previous history of abdominal and urogynecologic surgery, number of abortions and the presence of symptoms of depression and anxiety, were found to be factors associated with OBS.

Resumo Objetivo: Identificar os fatores clínicos e sociodemográficos associados à Síndrome da Bexiga Hiperativa (SBH). Método: Estudo transversal, realizado com idosas (>60 anos) da comunidade de Ceilândia, DF, Brasil; avaliadas por meio de entrevistas e questionários. As variáveis clínicas e sociodemográficas analisadas foram: idade; índice de massa corpórea (IMC); paridade, escolaridade, cirurgias abdominais e uroginecológicas prévias, prática de atividade física, tabagismo, constipação, hipertensão arterial sistêmica (HAS), diabetes mellitus; depressão e ansiedade. Os questionários aplicados foram Overactive Bladder Awerenees Tool (OAB-V8), Escala de Depressão Geriátrica e Escala de Ansiedade de Beck. Os dados foram analisados descritivamente. Utilizou-se a regressão logística binária para avaliar as associações significativas entre as variáveis independentes e o desfecho de interesse. As razões de risco foram calculadas para cada variável independente com intervalos de 95% de confiança. Resultados: Recrutou-se 372 voluntárias, sendo elegíveis 292, destas, 172 eram grupo caso (58,9%) e 120 (41,1%) eram grupo controle. Observou-se alta prevalência de SBH na população estudada, além de diferenças significativas para as variáveis: presença de HAS; ter realizado cirurgia abdominal ou cirurgia pélvica, sendo que o grupo caso apresentou maior frequência desses eventos. Na análise multivariada, observou-se que vida sexual ativa reduz em 70,8% a chance de ter SBH, e cirurgias uroginecológicas aumentam em 3,098 vezes esse risco. Conclusão: Na análise de regressão logística univariada, o IMC, a HAS, a história prévia de cirurgia abdominal e uroginecológica, quantidade de abortos, presença de sintomas de depressão e ansiedade, apresentaram-se como fatores associados à SBH.

ResumoObjetivo:Determinar a efetividade de 20 sessões de estimulação elétrica nervosa transcutânea (TENS) parassacral com periodicidade de duas vezes semanais no tratamento da urgência ou urge-incontinência urinária em crianças e adolescentes.Métodos:Ensaio clínico fase II, envolvendo pacientes com idade entre 5 e 14 anos com urgência ou urge-incontinência urinária. Realizadas 20 sessões de TENS, duas vezes por semana (aparelho Dualpex 961 Quark®). Os resultados foram avaliados pelo diário miccional, ultrassonografia dinâmica do trato urinário inferior (USGD-TUI) pré e pós-tratamento e questionário sobre perdas urinárias em cada sessão.Resultados:A idade média das 25 crianças envolvidas no estudo foi 7,80 ± 2,22 anos, sendo a maioria do sexo feminino (92%) e com urge-incontinência (92%). A comparação dos eventos de perda urinária pré e pós-tratamento foi estatisticamente significativa (p = 0,04); houve regressão do sintoma de perda urinária referida pelos acompanhantes em todas as crianças que completaram a 20ª sessão; os parâmetros da USGD-TUI, embora não estatisticamente significativos, demonstraram redução do percentual de crianças com contrações detrusoras (62,5% para 43,5%); maior adequação do volume vesical pré-miccional (4,2% versus 19,0%), respectivamente pré e pós-tratamento.Conclusões:A eletroestimulação realizada em duas sessões semanais demonstrou efetividade e metade dos pacientes apresentou regressão da incontinência urinária a partir da 12ª sessão, porém, é necessário maior número de pacientes para confirmação dos resultados obtidos.
AbstractObjective:To determine the effectiveness of 20 twice-weekly sessions of parasacral transcutaneous electrical neural stimulation (TENS) for treatment of urinary urgency and urge-incontinence in children and adolescents.Methods:A Phase II clinical trial was carried out with patients with urinary urgency or urge-incontinence aged between 5 and 14 years. Twenty TENS sessions were conducted, twice weekly, using a Quark® Dualpex 961 apparatus. The variables analyzed were daily micturition, dynamics ultrasonography of the lower urinary tract pre-and post-treatment and responses to a questionnaire on urinary leakage applied during each session.Results:The mean age of the 25 children participating in the study was 7.80 ± 2.22 years, most were female (92%) and had urge-incontinence (92%). The difference in urinary leakage pre- and post-treatment was statistically significant ( p = 0.04); a decline in the symptom of urinary leakage was reported by all caregivers in children who completed the 20th session; the ultrasound parameters, although not statistically significant, showed a reduction in the percentage of children with detrusor contractions (from 62.5% to 43.5%); and a more adequate pre-micturition bladder volume of 4.2% post-treatment compared with 19.0% prior to treatment.Discussion:The electro-stimulation carried out during the twice weekly sessions appeared to be effective and urinary incontinence declined in half of the patients from the 12th session onwards. However, there is a need for a study involving a larger number of patients to confirm the results obtained.

Identificar o impacto da incontinência urinária (IU) sobre a qualidade de vida (QV), comparar os escores dos domínios de QV em mulheres com incontinência de esforço (IUE), bexiga hiperativa (BH) e incontinência mista (IUM) e estabelecer a associação entre o tipo clínico de IU e o impacto sobre a QV. Foram coletadas informações sobre idade, índice de massa corpórea (IMC) e comorbidades de 181 mulheres incontinentes atendidas em serviço público. O Observou-se diferença significante entre os dois grupos de autoavaliação do impacto da IU para todos os domínios do KHQ. O grupo IUM apresentou piores escores que o grupo IUE para todos os domínios, e o grupo BH, para limitações de atividades diárias e físicas. Houve diferença significante entre as chances de as mulheres dos grupos IUE e IUM reportarem pior impacto de IU na QV (OR=2,9; p=0,02). Assim como em outras populações de serviços especializados, a IUM foi o subtipo mais comum, e a perda urinária comprometeu de forma moderada/grave a QV, afetando o domínio limitações das atividades diárias com maior intensidade. A análise ajustada mostrou que mulheres com IUM apresentam chance aproximadamente três vezes maior de reportarem pior impacto sobre ...
To identify the impact of urinary incontinence (UI) on quality of life (QoL), to compare the scores of QoL domains in women with stress urinary incontinence (SUI), overactive bladder (OAB) and mixed incontinence (MUI) and to establish the association between the clinical type of UI and the impact on QoL. Data of 181 incontinent women attended at a public hospital were collected regarding age, body mass index (BMI) and co-morbidities. King's Health Questionnaire (KHQ) was applied and patients were classified into two groups according to the self-assessment of incontinence impact. KHQ scores were compared by the Mann-Whitney test. Depending on their urinary symptoms, women were divided into SUI, OAB and MUI groups and their scores in the KHQ domains were compared by the Kruskal-Wallis and Dunn tests. The odds ratio (OR) of a woman reporting a worse effect of UI on QoL was estimated using the binary logistic model. The control variables were: age, BMI and number of co-morbidities. A significant difference was found between the two groups of self-assessment of UI impact for all KHQ domains. The MUI group showed worse scores than the SUI group for all domains, and OAB group, for limitation of physical and daily activities. There was a significant difference between the odds of the women in the SUI and MUI groups reporting worse effects of UI on QoL (OR=2.9; p=0.02). As reported at other reference services, MUI was the most commom type, and urinary loss had a moderate/major impact on QoL, affecting mainly role limitations domain. The adjusted analysis showed that women with MUI had almost three times greater odds of reporting worse impact on QoL than women with SUI.
