Removal of retained intrauterine contraceptive devices in pregnancy.

Using real-time ultrasound and clinical expertise gained from chorionic villus sampling, we describe a technique for ultrasound-guided intrauterine device removal in those cases in which the string is not visible. Utilizing a stone clamp for intrauterine manipulation, we were easily able to extract the device without interrupting the pregnancy. We concur with recent recommendations advocating all intrauterine devices can be removed if pregnancy termination is declined.
