Ultrasonic Identification of the Position of Contraceptive Device in Utero and its Relation to Subsequent Performance
Two diagnostic methods are available for the identification of a contraceptive device in utero, radiology and ultrasound. Radiology involves two views, the placement of a sound, or a second intrauterine contraceptive device (IUCD), or dye into the uterine cavity. In contrast, ultrasound is a simple, safe and reliable method for the localization of the device, allowing also recognition of such details as thickness of myometrium, exact sites of insertion of the Fallopian tubes and the uterine fundus. The devices used in this study were Cu-T and Cu-7. The examination was performed with a bi-stable and grey scale B-scanner using the full bladder technique.
