[Effectiveness and safety of non-surgical management for intrauterine retained products of conception: A prospective observational study].

OBJECTIVES: Intrantering retained products of conception (RPOC) are common postpartum or post-abortion complications. Although surgical management is effective, it carries risks such as endometrial injury and potential negative impacts on fertility. Retrospective studies suggest that non-surgical treatment may be safe and effective for selected patients with RPOC; however, prospective evidence remains lacking. This study aims to prospectively evaluate the effectiveness and safety of non-surgical management for RPOC. METHODS: Clinical data of patients diagnosed with intrauterine RPOC by ultrasound and presenting for the first time at the outpatient clinic of the Department of Gynecology and Obstetrics of the Third Xiangya Hospital, Central South University, from January 2023 to December 2024 were prospectively collected. Outcomes assessed included spontaneous expulsion of retained tissue, conversion to surgical treatment, and the incidence of heavy bleeding or infection during non-surgical management. RESULTS:
