结局指标
主要结局
Change in baseline microbiota composition at three months follow-up
时间窗: From baseline to three months follow-up
The microbiota composition is analyzed using sequencing of bacterial DNA. Comparison of healthy women without bladder symptoms receiving RCE (healthy RCE) at baseline to three months follow-up compared to controls (healthy PL) from baseline to follow-up. Healthy RCE from baseline to follow-up vs. Healthy PL from baseline to follow-up
Difference in baseline microbiota composition between women with and without UUI and OAB
时间窗: Baseline
The microbiota composition is analyzed using sequencing of bacterial DNA. Is there a difference in the urinary, vaginal and gut microbiota in women with and without urge urinary incontinence (UUI) and overactive bladder (OAB) at baseline? Symptomatic PL baseline vs. Healthy PL baseline
Change from baseline microbiota composition in women suffering from UUI and OAB at three months follow-up
时间窗: From baseline to three months follow-up
The microbiota composition is analyzed using sequencing of bacterial DNA. We are investigating the urinary, vaginal and gut microbiota. In women with urge urinary incontinence (UUI) and overactive bladder (OAB) receiving RCE (symptomatic RCE), a possible change in the urinary, vaginal and fecal microbiota composition from baseline to three month follow-up, compared to controls receiving placebo (symptomatic PL) are investigated. Symptomatic RCE from baseline to follow-up vs. Symptomatic PL from baseline to follow-up
