Intrauterine device (IUD) is widely used for the long duration of protection, cost-effectiveness and for being a reversible contraceptive method as well as having low complication rates. Despite low complication rates, various IUD-related complications, such as spontaneous aborts, bleeding, infection, and uterine perforation may occur. Although perforation of the uterus by an IUD is not uncommon, bladder perforation is a rare complication. A regular follow-up of patients with IUDs for the complications and training of clinicians for insertion and removal are mandatory to provide better and safe family planning services. Here, we report a case of a patient with uterine perforation with a calcified IUD migration into the the bladder.
