Drug-assisted expectant care versus surgery for retained products of conception

A Prospective Multicenter Observational Real-world Study of Retained Products of Conception

Observational The Third Xiangya Hospital of Central South University · NCT07421895

This project tests whether trying drug-assisted expectant management and waiting for the right time for surgery in people with retained products of conception reduces intrauterine scarring and better preserves fertility compared with immediate curettage.

What this trial studies

This is a prospective multicenter observational real-world study conducted at hospitals in Hunan, China. Patients with a clinical diagnosis of retained products of conception and an ultrasound lesion ≥0.5 cm will be followed after receiving either uterine curettage or drug-assisted expectant management until the clinician decides on surgery timing. The study will record rates of intrauterine adhesions and other fertility-related outcomes, as well as need for repeat procedures, infection, and bleeding. Patients with active bleeding requiring immediate surgery, obvious infection, or severe organ dysfunction are excluded and data will be used to compare real-world safety and effectiveness of the two approaches.

Who should consider this trial

Good fit: Ideal candidates are people with clinically diagnosed retained products of conception, an ultrasound lesion at least 0.5 cm in diameter, and no active bleeding, obvious infection, or severe organ dysfunction.

Not a fit: Patients with active heavy bleeding, clear infection, or severe organ dysfunction are unlikely to benefit from expectant management and will require immediate or alternative care.

Why it matters

Potential benefit: If successful, this approach could reduce intrauterine adhesions and help preserve future fertility by avoiding or better timing surgery.

How similar studies have performed: Some prior case series and observational reports suggest expectant or medical management can reduce immediate surgical interventions, but evidence that such approaches lower intrauterine adhesion rates is limited and mixed.
