This is a randomized, double blinded placebo controlled trial over a period of 3 months. Study subjects will be randomized into 2 groups: Those receiving drug (1gm of estrogen vaginal cream [EVC] at bed time 3 times a week), and those receiving placebo.


1. This will be a randomized, double blinded placebo controlled trial over a period of 3 months. Study subjects will be randomized into 2 groups: Those receiving drug (1gm of estrogen vaginal cream [EVC] at bed time 3 times a week), and those receiving placebo. Study subjects will be patients diagnosed with stress urinary incontinence by urodynamic evaluation. They will have filled out the IIQ-7 and UDI-6 validated questionnaires as is routine for all patients being evaluated for stress incontinence. After enrollment and informed consent, their initial screening will include a Pap smear for vaginal maturation.

2. Subjects will then be seen at 4, 8 and 12 weeks. At each visit, they will turn in their medication tubes and receive new study medication. They will also be screened for any adverse reaction to the study medication at each visit.

3. At the end of the study period, the subjects will fill out the same validated questionnaire as they did at the beginning of the study and they will also have their urethral pressure profile and PAP smear repeated.

4. The urethral pressure profile is part of the standard complex urodynamic testing that all patients undergo for evaluation and diagnosis of urodynamic stress incontinence. Urethral Pressure Profile is a technique used to provide information about the ability of the urethra to prevent leakage. The Urethral Pressure Profile is a specific study, in which a special design catheter is pulled through the urethra at a slow, continuous rate. The resulting "bell shaped" curve illustrates the function of the urethra from the beginning of the bladder neck out through the meatus.

5. The placebo cream will be a pharmacologically inert formulation which will be packaged similarly to the active premarin cream and visually indistinguishable from the active drug to both the study subjects and researchers.
