Abstract
OBJECTIVES: To evaluate the safety and effectiveness of ultrasound-guided instrumental removal of retained placenta. CASE PRESENTATION: We presented a retrospective single-center cohort study include 54 patients diagnosed with retained placenta after delivery. The characteristics of the patients with retained placenta, who received ultrasound-guided instrumental removal, were evaluated. We also compared the characteristics between the patients with retained placenta with and without suspected placenta accrete. CONCLUSION: Curettage should be performed in retained placenta without suspected placenta accrete. In retained placenta with suspected placenta accrete, we could also perform ultrasound-guided instrumental removal therapy if the retained placenta was not in the lower uterine segment or in previous scars.
