title: Analysis of 100 cases of missing IUD strings.
abstract: In a study of 100 patients with missing IUD strings 69 women had their IUD in utero (4 were pregnant) and 17 had unnoticed expulsions (4 pregnancies); 9 devices were in the peritoneal cavity and one had perforated the cervix. Since the IUD was in the uterine cavity in the majority of these cases, most contraceptors whose IUD strings disappear can be managed in the office or clinic with relatively simple techniques to locate and remove the device.
