Abstract
The intrauterine contraceptive device is the most commonly used, safe, and reversible method of contraception. However, this contraceptive method is not without complications. Migration of a device into adjacent organs is the most morbid of all the documented complications. A history that suggests the loss or disappearance of an intrauterine device in a patient with urinary symptoms must suspect intravesical migration. We present a case report describing the migration of an intrauterine contraceptive device into the bladder secondarily calcified.
