Официальное название
A Clinical Study on the Safety and Efficacy of Estradiol-Loaded Silicone Rubber Intrauterine Stent System for Promoting Endometrial Repair After Induced Abortion
Обзор
The purpose of this clinical trial is to evaluate the safety and efficacy of the estradiol-loaded silicone rubber intrauterine stent system for promoting endometrial repair after artificial abortion. The main research questions it aims to answer are: 1. Can the estradiol-loaded silicone rubber intrauterine stent system increase the endometrial thickness at 21+2 days after the procedure? 2. What adverse events or safety issues occur in participants when using this product? Researchers will compare the estradiol-loaded silicone rubber intrauterine stent system with a non-drug-loaded silicone intrauterine stent to determine whether the drug-eluting stent offers advantages in promoting endometrial repair. Participants will: 1. Undergo placement of either the estradiol-eluting stent or the non-drug stent immediately after artificial abortion, with the stent retained for 21+2 days 2. Attend scheduled follow-up visits at 21+2 days, after the first menstruation, and at 90 days post-procedure. 3. Undergo ultrasound examinations to measure endometrial thickness, and record vaginal bleeding duration, blood loss volume, time to first menstruation, and any adverse events
Вмешательства
- Устройство Estradiol-Loaded Silicone Rubber Intrauterine Stent System
After abortion, an estradiol-loaded silicone rubber intrauterine stent system was placed for 21+2 days, and oral anti-infective medication was administered for 3 days postoperatively. - Устройство No-Drug-Loaded Silicone Rubber Intrauterine Stent System
After abortion, a no-drug-loaded silicone rubber intrauterine stent system was placed for 21+2 days, and oral anti-infective medication was administered for 3 days postoperatively.
Первичные конечные точки
- Endometrial thickness [Срок оценки: at 21 + 2 Days Postoperatively]
Вторичные конечные точки (4)
- Vaginal bleeding volume [Срок оценки: 14 days post-surgery]
- Vaginal bleeding duration [Срок оценки: 14 days post-surgery]
- Time to menstrual resumption after abortion [Срок оценки: Followed up and recorded within 60 days after induced abortion surgery (if no menstruation occurs by day 60, it will be recorded as "no resumption within 60 days").]
- Changes in menstrual blood volume at first menstrual period post-abortion [Срок оценки: Assessed at the end of the first menstrual period after abortion, with follow-up and recording completed within 60 days post-abortion.If no menstruation occurs by day 60, it will be recorded as "no resumption within 60 days".]
