Summary

This trial will investigate why vaginal estrogen therapy works for some post-menopausal women with recurrent UTI, to help prevent these infections.

Who is the study for?
This trial is for postmenopausal women aged 55 or older who have had at least 3 UTIs in the past year or 2 within the last 6 months, with one confirmed by urine culture. It's not for those currently on antibiotics to prevent UTIs, those with contraindications to vaginal estrogen, recent antibiotic use, complicated recurrent UTI due to other health issues.
What is being tested?
The study tests if vaginal estradiol tablets can prevent recurrent urinary tract infections in postmenopausal women. It examines how this treatment affects vaginal and bladder bacteria and immune responses to understand why it helps some women but not others.
What are the potential side effects?
Potential side effects of vaginal estradiol may include local irritation or discomfort, changes in discharge, and a slight increase in certain types of cancer risk as seen with other forms of estrogen therapy.
