Intrauterine Adhesion, Intrauterine Adhesions
Conditions
Brief summary
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.
Interventions
DEVICEUterine stent group
After TCRA, uterine stents of different specifications were placed in the uterine cavity according to the different uterine cavity morphologies of the subjects, and the hysteroscope was inserted again to adjust the position of the uterine stent.
DEVICEUterine ring + balloon + sodium hyaluronate gel
The subjects were hospitalized for TCRA surgery. After the surgery, different types of uterine rings were selected and inserted into the uterine cavity according to the morphology of the subjects' uterine cavity. At the same time, a No. 12 Foley catheter was left in the uterine cavity, and 2.5 ml of normal saline was injected into the catheter balloon. 2 ml of hyaluronic acid gel was injected into the uterine cavity on one side of the catheter. The doctor removed the Foley catheter on the first day after the surgery.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Intrauterine adhesion rate | At 12 months after the index hysterectomy | Refer to the 2017 American Fertility Association IUA guidelines AFS score. AFS score: The case with adhesion whose total AFS score decreased by ≥ 4 points was considered effective. The effective rate was calculated using the following formula: number of cases with total AFS score decreased by ≥ 4 points/total number of cases × 100%. |
