Migration of Intra-Uterine Devices

Intrauterine devices (IUDs) are a widely used contraceptive. Possible complications from IUDs include failed insertion, pain, vasovagal reaction, infection, abnormal bleeding, and expulsion. Uterine perforation and migration of the IUD are rare complications occurring in approximately 1-2 per 1000 insertions. We executed a systematic review by reviewing all case reports and case series on IUD migration, published between December 2002 and December 2022. Our review indicates that about half of these patients present with pain and that a third are completely asymptomatic. The most common sites of migration are the intestine, bladder, and omentum. We found that the preferred method for removing the migrated IUD is laparoscopy. Generally, there are no lasting injuries after the removal of the migrated IUD, but occasionally, severe complications have been reported. Healthcare providers should be vigilant about this rare complication, especially in cases of painful insertion or the presence of other risk factors for perforation. When uterine perforation is diagnosed, it is advisable to remove the IUD to prevent severe complications.
