[Uterine perforation and vesical migration of intrauterine device]. / Perforación uterina y migración vesical de un dispositivo intrauterino.

Cases of uterine perforation through to the bladder during the placement of an intrauterine device are rare. There have been only 25 previous reported cases. This type of perforation is no different to any other by an intravesical foreign body. A detailed anamnesis and sonographic examination is usually sufficient to provide a diagnosis. Complications can be diagnosed by an uretrocytoscopy which is also therapeutic in non-complicated cases. If there are associated complications surgery can be necessary. In conclusion, quick detection of any complication, by sonographic detection after placement, assists in the extraction of the foreign body and avoids the appearance of associated complications such as lithiasis.
