Ureteral displacement due to a migrated intrauterine contraceptive device.

Perforation of the uterus is rare but potentially fatal. During puerperium when the uterus is small and its wall is thin, the risk of perforation increases. We report a rare complication from an intrauterine contraceptive device (IUD) which caused deviation of the right ureter in a 31-year-old woman who presented with complaints of insomnia and abdominal pain. Our case shows that perforation of the uterus by an IUD can cause a silent urological complication. The possibility of ureteral involvement and displacement should be kept in mind in a woman in whom a missing IUD is encountered.
