An interventional study of Uterine stent group and Uterine ring + balloon + sodium hyaluronate gel in Intrauterine Adhesion and Intrauterine Adhesions, sponsored by The Third Xiangya Hospital of Central South University. Recruiting at 1 site in China. Open to female participants aged 20 Years to 40 Years. Per ClinicalTrials.gov, last updated 2026-05-28.

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.

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Uterine stent placement in the uterine cavity after hysteroscopic intrauterine adhesion separation surgery
Device: Uterine stent group
Uterine cavity insertion ring + balloon + sodium hyaluronate gel
Device: Uterine ring + balloon + sodium hyaluronate gel
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.
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.
Intrauterine adhesion rate
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%.
Time frame: At 12 months after the index hysterectomy

Started Jan 2021 (actual). Primary completion is estimated for Dec 2026, 71 months after the start.
Of 46 interventional studies with no phase under Gynatresia, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 77. This study's planned 71 months is above that.
How these figures are worked out, and which studies are left out of them.
