Asherman's syndrome is characterized by the presence of intrauterine adhesions (IUA) as well as symptoms such as amenorrhea, hypomenorrhea, pelvic pain, and infertility. The gold standard for the treatment of intrauterine adhesions is hysteroscopic intrauterine adhesions. The recurrence of intrauterine adhesions is a major challenge in clinical practice. Intrauterine balloon has been used for the prevention of intrauterine adhesions. It has been reported that dried biological amnion graft was used to prevent adhesion after the operation of intrauterine adhesions. Estrogen is also used for postoperative prevention of intrauterine adhesions. Intrauterine balloon can reduce the recurrence of adhesions after operation. Disposable balloon uterine stent,which is an innovative intrauterine balloon,is specially designed to fit into the cavity of the uterus. Does Disposable balloon uterine stent and amniotic products combine estrogen therapy improve clinical outcomes? Therefore, this study was conducted.
