About

To evaluate the effect of uterine stents in preventing intrauterine adhesions after intrauterine operation and whether they meet the safety requirements for clinical use. The trial adopted a prospective, multicenter, randomized controlled, non-inferiority clinical trial design. The target population of the trial was 200 women aged 20-40 years with intrauterine adhesions and surgical indications (referring to those with fertility requirements or menstrual blood drainage obstruction), who were randomly divided into an experimental group and a control group, with 100 cases in each group. The experimental group was the group with intrauterine stents placed in the uterine cavity after hysteroscopic intrauterine adhesion separation surgery, and the control group was the group with intrauterine rings + balloons + sodium hyaluronate gel placed in the uterine cavity. After 3 courses of artificial cycles, the patients were hospitalized for hysteroscopy review.
