Summary
This study randomizes postmenopausal women with symptomatic pelvic organ prolapse planning native tissue transvaginal surgical repair to 6-8 weeks of preoperative and 1-year continued postoperative vaginal estrogen cream compared to placebo cream. This clinical trial and basic science investigation are designed to understand the mechanisms by which local estrogen treatment affects connective tissues of the pelvic floor and determine whether its use before and after prolapse repair will (i) improve success rates of the surgical intervention and minimize prolapse recurrence and (ii) impact favorably upon symptoms of other pelvic floor disorders.
Eligibility Criteria
