Retained products of conception（RPOC）are tissues that remain in the uterus after a miscarriage or delivery. Although management guidelines have not been established and treatment methods vary widely, excessive intervention should be avoided to prevent complications such as infertility. This retrospective study evaluated the effectiveness of conservative management for RPOC in our hospital between January 2015 and May 2023. Forty-one cases of RPOC treated initially with conservative management were included. In 37 cases（90.2％）, RPOC naturally disappeared with observation alone, whereas 4 cases（9.8％）required additional intervention（all 4 received uterine artery embolization in combination with dilatation and curettage; 2 additionally underwent transcervical resection）. The median duration until the disappearance of RPOC with conservative management was 150 days. In conclusion, conservative management is reasonable for most cases of asymptomatic RPOC, although patients should be monitored for severe postpartum hemorrhage.
