1. Maintaining uterine cavity shape: Physical support prevents postoperative intrauterine adhesions; metal stents can last 6-12 months.
2. Preventing adhesion recurrence: Silicone stents can reduce the recurrence rate of moderate intrauterine adhesions, and when combined with hormone therapy, accelerate endometrial repair.
3. Assisted reproduction: Temporary stents can improve uterine cavity volume and increase embryo implantation rates; absorbable stents degrade in 3-6 months.
4. Special treatment: Pelvic floor stents relieve uterine prolapse, and bioactive stents promote endometrial regeneration.
