ClinConnect Summary
This clinical trial is studying how vaginal estrogen therapy might change the bacteria in the urine of menopausal women who have overactive bladder (OAB) symptoms. The main goal is to see if using vaginal estrogen can increase the levels of a type of healthy bacteria called Lactobacillus in the urine, and how this might help improve OAB symptoms. If you are a postmenopausal woman experiencing OAB symptoms and have not used hormone therapy in the last three months, you might be eligible to participate in this study.
Participants will be asked to use a small tablet of vaginal estrogen daily for two weeks, and then twice a week for a total of 12 weeks. After this period, researchers will collect urine samples to study the urinary bacteria. It’s important to note that candidates should not have any urinary infections or other specific health issues, and they should not be on certain medications that could interfere with the study. This trial is a chance to help understand how hormonal changes can affect urinary health in menopausal women.
