A combined 4D ultrasound, hysteroscopic cold-knife plowing, uterine stent, and traditional Chinese medicine approach for intrauterine adhesions

Investigating the Association Between Diagnostic and Therapeutic Management Models and Prognosis of Intrauterine Adhesions Based on a Large-Scale Prospective Cohort Study

Not applicable Interventional The Third Xiangya Hospital of Central South University · NCT07421908

This project will try a combined care pathway—preoperative 4D ultrasound, hysteroscopic cold-knife adhesion separation, a postoperative uterine stent, and traditional Chinese medicine—to see if it improves outcomes for women aged 18–45 with intrauterine adhesions.

What this trial studies

This is a prospective, multicenter real-world cohort enrolling up to 5,000 cases (2,000 at the lead center) of women aged 18–45 treated for intrauterine adhesions. Patients receive preoperative four-dimensional color ultrasound, intraoperative integrated hysteroscopy with cold-knife plowing for immediate adhesion separation, placement of a patented uterine cavity stent to prevent re-adhesion, and postoperative traditional Chinese medicine prescriptions to promote endometrial repair. Follow-up uses 4D ultrasound combined with intraoperative AI gland-density counts and multimodal data fusion to build a postoperative infertility risk prediction model and track pregnancy outcomes. The study aims to test feasibility and real-world effectiveness of the full management model across participating centers.

Who should consider this trial

Good fit: Women aged 18–45 diagnosed with intrauterine adhesions at the participating centers who can comply with diagnosis, treatment, and follow-up are ideal candidates.

Not a fit: Patients with abnormal ovarian function, primary male-factor infertility, or who cannot adhere to treatment and follow-up schedules are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the combined pathway could reduce adhesion recurrence, improve endometrial recovery and pregnancy outcomes, and reduce the need for repeat hysteroscopies.

How similar studies have performed: Components such as hysteroscopic adhesiolysis and uterine stents have mixed evidence and traditional Chinese medicine has variable support, while the integrated model with cold-knife plowing, 4D ultrasound follow-up, and AI gland-density analysis is novel and not yet proven in large cohorts.
