Summary

This trial aimed to compare the two methods of vaginal estrogen application.

Who is the study for?
This trial is for postmenopausal women who've had at least 2 UTIs in the last 6 months or 3 in a year, and are recommended vaginal estrogen to prevent more UTIs. They shouldn't be currently using any estrogen products, have significant vaginal narrowing, bladder stones, risk of estrogen-dependent cancer, or conditions preventing them from applying the cream themselves.
What is being tested?
The study compares two ways of using estradiol cream to prevent recurrent urinary tract infections: periurethral (around the urethra) versus intravaginal application. It aims to determine if applying less cream around the urethra is as effective as the standard intravaginal method.
What are the potential side effects?
While not explicitly listed here, typical side effects of topical estradiol may include local irritation or itching, increased chance of developing a rash or infection at the site of application.
