Management of fluid intake in patients with overactive bladder

Objectives:To evaluate the effect of caffeine at the dose of 4.5 mg/kg on bladder function in overactive bladder (OAB) adults.Materials and Methods:Nine women and three men aged 21-40 years with OAB symptoms were included. Each subject drank 8 ml/kg of water with and without caffeine at two separate sessions. Cystometry and uroflowmetry were performed 30 minutes after each drink. The effects of caffeine on urodynamic parameters were compared.Results:After caffeine ingestion, the mean volume at bladder filling phase decreased at first desire to void and normal desire to void (P<0.05), compared to the mean volume after taking water (control) drink. The mean volume at strong desire to void, urgency and maximum cystometric capacity also tended to decrease. No change in the detrusor pressure at filling phase was found. At voiding phase, the maximal flow rate, average flow rate and voided volume were increased (P<0.05). The urine flow time and time to maximal flow rate were not changed.Conclusion:Caffeine at 4.5 mg/kg caused diuresis and decreased the threshold of sensation at filling phase, with an increase in flow rate and voided volume. So, caffeine can promote early urgency and frequency of urination. Individuals with lower urinary tract symptom should avoid or be cautious in consuming caffeine containing foodstuffs.

“…This finding agrees with the concept that coffee or caffeine aggravates the OAB symptoms and caffeine restriction can be beneficial. [16–20]…”

“…(1, 2) This recommendation is based on evidence that caffeine promotes diuresis(3, 4) and increases detrusor pressure(5), which, together, might increase the likelihood of urgency-related involuntary urine loss. Yet, the available data on caffeine restriction and UI, derived from several small, short-term trials, are equivocal.…”

Objective To estimate the association between long-term caffeine intake and risk of urinary incontinence (UI) progression over 2 years among women with moderate UI. Methods We conducted a prospective cohort study in 21,564 women with moderate UI enrolled in the Nurses’ Health Study and Nurses’ Health Study II. Incontinence progression was identified from questionnaires during 2 years of follow-up. Baseline caffeine intake (ie, average intake during the past year) and change in caffeine intake during the 4 years prior to baseline were measured using food frequency questionnaires. Odds ratios (ORs) for incontinence progression according to caffeine intake were calculated for each cohort separately, and then for both cohorts combined. Results The percentage of women with UI progression was similar across categories of baseline level of caffeine intake and change in caffeine intake prior to baseline. For example, percentages were 21% versus 22% comparing 450 mg or more to less than 150 mg of caffeine per day (adjusted OR 0.87, 95% confidence interval [CI] 0.70-1.08). Comparing women with increased caffeine intake to those with stable caffeine intake, percentages with progression were 22% versus 20% (OR 1.08, 95% CI 0.95-1.22). Results were similar in separate analyses of urgency and stress UI. Conclusion Long-term caffeine intake over one year was not associated with risk of UI progression over 2 years among women with moderate incontinence, although we could not examine acute effects of caffeine. Improved understanding of the effect of caffeine on the bladder is needed to better advise women with incontinence about caffeine intake.

“…Sabese que a ingestão elevada de sódio está relacionada com o desenvolvimento de hipertensão e que a hipertensão favorece o desenvolvimento de IU, no entanto a ingestão de sódio é relativamente difícil de ser capturada usando-se o QFA 11 . Neste estudo não houve diferença na quantidade de água consumida entres as mulheres com e sem IU, contudo a ingestão de líquidos é conhecida por ter um impacto significativo nos sintomas do trato urinário 28 . Destaca-se que neste estudo não foi avaliado o consumo total de líquidos, o que pode ter contribuído para ausência de associação com a incontinência urinária.…”

Cad. Saúde Colet., 2018, Rio de Janeiro, 26 (1) ResumoObjetivo: Avaliar a relação entre incontinência urinária e ingestão de energia e de nutrientes em mulheres adultas. Método: Estudo transversal com 382 mulheres (≥ 18 anos) atendidas em uma Unidade de Atenção Primária à Saúde em Fortaleza, CE. A avaliação da IU foi realizada através do International Consultation on Incontinence Questionnaire -Short Form (ICIQ-SF) e a do consumo alimentar, através de um questionário de frequência alimentar (QFA). A ingestão de nutrientes foi ajustada pela ingestão total de energia, usando-se o método residual. Modelos de regressão logística foram utilizados para testar a associação entre IU e ingestão de energia e nutrientes. Resultados: Mulheres com ingestão elevada de colesterol apresentaram maior razão de chance de desenvolver IU (quarto quartil vs. primeiro quartil: RC ajustada = 2,26; IC 95% = 1,19-4,29), independentemente de fatores sociais, demográficos e de saúde. Nenhuma associação foi observada entre a ingestão de energia, macronutrientes, frações lipídicas, sódio e fibra e IU, entretanto houve maior ingestão de proteínas e menor de sódio entre as mulheres com IU (p < 0,05). Conclusão: Foi observado no presente estudo associação somente entre ingestão de colesterol e IU. Análises dos tipos de alimentos consumidos podem contribuir na avaliação da influência de fatores dietéticos na IU. Palavras-chave: incontinência urinária; mulheres; dieta. AbstractObjective: To evaluate the relationship between urinary incontinence and energy and nutrient intake among adult women. Method: A cross-sectional study was carried out with 382 women (≥ 18 years old) attended in a Primary Health Care Service in Fortaleza-CE. The evaluation of IU was performed using the International Consultation on Incontinence Questionnaire -Short Form (ICIQ-SF) and food intake was estimated through a food frequency questionnaire (FFQ). Nutrient intake was adjusted for total energy consumption, using the residual method. Logistic regression models were used to test the association between the consumption of energy and nutrients, and IU. Results: Greater cholesterol consumption was associated with UI (fourth quartile vs. first quartile: adjusted OR =2.26; IC 95%=1. 19-4.29). No association was observed with the consumption of energy, macronutrients, lipid fractions, sodium and fiber, and UI, however there was a greater intake of protein and lower sodium intake among women with urinary incontinence (p <0.05). Conclusion: This study found an association only between cholesterol intake and IU. Specific analysis of the types of food consumed should be developed to better assess the influence of dietary factors on UI.
