Advances in the treatment of retained products of conception.

Retained products of conception (RPOC) represent a common pregnancy-related condition that may lead to complications such as abnormal uterine bleeding, infection, secondary arteriovenous fistula, intrauterine adhesions, and infertility. Currently, the main clinical treatments for RPOC include surgical intervention, medical therapy, and expectant management, sometimes supplemented by high-intensity focused ultrasound or uterine artery embolization when necessary. However, no standardized treatment guidelines exist. Medical and expectant management may help some patients avoid or reduce the need for surgery, though these approaches often involve a prolonged disease course. While surgery yields rapid results, patients with large lesions may require multiple procedures, increasing the risk of endometrial damage and intrauterine adhesions. There is still a lack of robust evidence-based guidance for selecting the optimal or individualized treatment approach. This review explores recent advances in the management of RPOC, with an emphasis on strategies that effectively preserve the endometrium, safeguard fertility, and support more precise, minimally invasive, and efficient personalized treatment.
