Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 18 to 39 who have had a first trimester miscarriage and wish to conceive again within six months.

Probably not a fit

Patients who are not planning to achieve pregnancy soon, those with repeated miscarriages, or those with severe medical conditions may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of operative hysteroscopy compared to expectant management in women who have experienced a miscarriage and have retained products of conception (RPOC) as confirmed by ultrasound. The study aims to determine which approach leads to a quicker return to pregnancy for women wishing to conceive again. It is a multicenter, randomized controlled trial that will assess not only the time to the next pregnancy but also the quality of life, safety, and cost-effectiveness of both treatment options. Participants will be monitored for complications and the course of any subsequent pregnancies.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for women with RPOC, potentially leading to quicker pregnancies and better overall reproductive health.

How similar studies have gone: Previous studies have indicated that medical management can be effective for RPOC, but this specific approach using hysteroscopy is being evaluated for the first time in this context.
