Hormonal Status on Blood Flow and Tissue in Pelvic Organ Prolapse

Role of Hormonal Status on Vascularization and Vaginal Tissue in Women With Pelvic Organ Prolapse

Our primary aim in the current study is to determine important tissue differences, including muscle and connective tissue changes, between postmenopausal women and reproductive age women with pelvic floor dysfunction to help develop targeted and noninvasive treatments.

Study Overview

• Status: Terminated
• Conditions: Pelvic Floor Disorders
• Intervention / Treatment: Drug: Postmenopausal, topical vaginal estrogen cream; Drug: Placebo Comparator: Postmenopausal, topical placebo cream

Detailed Description

Our primary aim in the current study is to determine important tissue differences, including muscle and connective tissue changes, between postmenopausal women and reproductive age women with pelvic floor dysfunction to help develop targeted and noninvasive treatments. We will perform in vivo evaluations with colposcopy and OCT to determine epithelial thickness and overall mucosal health prior to surgery. At the time of surgery, we will obtain tissue for histologic and imaging analysis.

Description

Inclusion Criteria:

• Stage II or greater pelvic organ prolapse (POP)
• Individuals electing surgery to treat their POP

• History of connective tissue disease
• Previous hysterectomy or pelvic organ prolapse surgery
• Known allergic reaction to any agent required by the protocol

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Postmenopausal, topical vaginal cream; Postmenopausal participants randomized to topical vaginal cream containing estrogen or placebo for about one month's use prior to scheduled surgery. These will include those women randomized to estrogen cream.	Drug: Postmenopausal, topical vaginal estrogen cream; Topical vaginal estrogen cream is commonly but not universally used to improve the health of vaginal tissue prior to surgery. This study will provide data regarding estrogen effects for post-menopausal women undergoing pelvic organ prolapse.; Other Names: Estrace vaginal cream
No Intervention: Pre-menopausal, no topical vaginal cream; Pre-menopausal, no topical vaginal cream. These women will be examined at different stages in their menstrual cycle in order to compare characteristics of the cycle at high and lower estrogen timepoints.
Placebo Comparator: Postmenopausal, topical placebo cream; Postmenopausal participants randomized to topical vaginal cream containing estrogen or placebo for about one month's use prior to scheduled surgery. These will include those women randomized to placebo.	Drug: Placebo Comparator: Postmenopausal, topical placebo cream; Postmenopausal participants randomized to topical vaginal placebo for about one month's use prior to scheduled surgery.; Other Names: Placebo vaginal cream
