Colposcopy in the localization of missing intrauterine devices.

The use of colposcopy as an office procedure is shown to be an effective method in localizing the IUD's string deep in the cervical canal, and for following those patients who wish to continue with IUD, thus avoiding replacement of the device. In 24 patients with missing string, colposcopy was used, and was found to be an effective procedure which obviates the use of unnecessary x-ray exposure, invasive procedures and expensive ultrasonography.
