Over Active Bladder: MRI Sub-Study


The Women's Health Research Unit is conducting a study to determine if the bacteria in the urinary tract contribute to Overactive Bladder Syndrome (OAB). Currently, the underlying causes and biology of Overactive Bladder Syndrome are largely unknown. Many women suffer from this condition which can significantly affect a woman's happiness and lifestyle. In order to treat something effectively, doctors and scientists must understand what causes it. This study seeks to better understand how the urinary microbiome affects OAB with the hopes of improving treatment practices for women who suffer from this condition. 

The purpose of this study is:

  1. to determine if there is a significant difference in the quantity and types of bacteria present in the urinary microbiome of women with OAB compared to women without OAB, independent of menopausal status.
  2. To determine if the urinary microbiome is related to changes in brain activity in women with and without OAB.


You may be eligible for this study if:

  • You are a woman between 55-80 years of age.
  • You are in good general health
  • Are able to undergo magnetic resonance imaging (MRI)
  • Either have normal bladder function OR overactive bladder syndrome


The study requires only one study visit to OHSU and qualified participants will be compensated up to $50 for time and travel for this study.
