Vaginal estrogen cream
Brief summary
The primary purpose of this two-arm randomized clinical trial is to determine if in women desiring use of a pessary for pelvic organ prolapse (POP) and are successfully fit, if 1-year use and patient impression of improvement is superior in women using vaginal estrogen cream versus those using a vaginal placebo cream.
Detailed description
The study is a multi-center, randomized trial of women with symptomatic utero-vaginal or post-hysterectomy vaginal vault prolapse desiring non-surgical treatment with a pessary. This study will compare outcomes in women randomized to vaginal estrogen cream or vaginal placebo cream. Women who meet the inclusion/exclusion criteria will be evaluated. A pessary (ring with support) will be fit by an experienced physician. After successful pessary fitting, they will be randomly divided into experimental active medication and control groups. The experimental group will start intravaginal estrogen cream, and the control group will start intravaginal estrogen-free cream. Then patients will be followed every 3months until 1year. The purpose of this trial is to evaluate the effect of intravaginal estrogen use on pessary treatment for pelvic organ prolapse, including short-term and long-term use rate, patient impression of improvement, improvement in symptom-specific quality of life and complication incidence.
Interventions
DRUGVaginal Cream with Applicator [Dose Form]
Patients with symptomatic POP will be assigned as outpatients. After the initial pessary fitting, the patients will be followed up in 2 weeks. If the prolapse is supported, no discomfort, and the patient decides to continue to use the pessary, the pessary fitting is successful. Patients with successful ring pessary fitting, who agree to participate and sign written consent, will be randomized into the vaginal estrogen group and the placebo group. The patients will be followed up every 3 months after wearing pessary combined with vaginal medication, until 1 year after wearing the pessary.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The proportion of subjects using the pessary and have very much or much improvement on the patient impression of improvement questionnaire at 1 year between the vaginal estrogen group and the placebo group. | up to 1year after randomization | 1. Sustained wearing with satisfaction: continuous wearing is defined as the use of the pessary after successful fitting test. The continuous wearing time interval is from the start of wearing the pessary to cessation of pessary use. 2. PGI-I （patient global impression of improvement））is used to evaluate patient impression of improvement. PGI-I is divided into seven levels: very much better, much better, a little bit better, no change, a little bit worse, much worse and very much worse. The patient's response of very much better and much better is defined as a successful impression of improvement. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 1. Comparison of symptom specific distress (PFDI-20) at 6 months and one year in subjects using the pessary in the vaginal estrogen group and the placebo group at 1 year. | up to 1year after randomization | Questionnaire survey: Relief of symptoms using validated instruments, Pelvic Floor Distress Inventory-20 。PFDI-20 scores 0-300, The higher the score is, the more serious the symptoms of PFD are, the greater the impact on the life of the patients. |
| 1. Comparison of symptom specific impact (PFIQ-7) at 6 months and one year in subjects using the pessary in the vaginal estrogen group and the placebo group at 1 year. | up to 1year after randomization | Questionnaire survey: Relief of symptoms using validated instruments, pelvic floor impact questionnaire short form 7(PFIQ-7)。PFIQ-7 scores 0-300, the higher the severer negative influence on patient. |
| 1. Comparison of sexual function (PISQ-12) at 6 months and one year in subjects using the pessary in the vaginal estrogen group and the placebo group at 1 year. | up to 1year after randomization | Questionnaire survey: Relief of symptoms using validated instruments, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form(PISQ-12), PISQ-12 scores 0-48, the higher, the severer negative influence on patient. |
| Comparison of the adverse events of subjects wearing a pessary in the vaginal estrogen group and the placebo group at 1 year. | up to 1year after randomization | Complications will be asked and reported during each follow-up |
