MATERIAL and METHODS:
A descriptive, cross-sectional prospective study from 2005 to 2010 in Medic Medical Center, HCM City. When X-rays detects a mispositioned IUD, the patient will be reexamined by ultrasound and then by CT.
05 cases of uncomplicated migrating and 01 case of complicated migrating. All of uncomplicated cases happened in over 50 year-old patients without clinical signs. Most of cases with Dana IUD type, and one case had removed the uterus (case 5). One case has a perforation of the rectum by one of two T shape type IUDs which exist together in a patient suffering bloody stools and abdominal pain for 2 years. An other case has 2 kinds of IUD together (case 4): one Dana and other T shape IUD type.
One case on the left side of abdominal cavity. 4/6 cases on the right side. Ultrasound itself cannot disclose migrating IUD. Ultrasound failed to detect an intraabdominal IUD (case 3). Intra-abdominal migrating IUDs were uncertain masses of 21-45mm with mixed and hyperechoic pattern without acoustic shadowing.
Migration of IUD may happen in women having IUD. X-rays has effective role to detect the intra and extrauterine IUD. Ultrasound discloses difficultly intraabdominal migrating cases. CT scan reveals exactly the migrating IUD inside / outside of hollow viscera (uterine tube, bladder, colon, appendix).
