Intrauterine Contraceptive Device Migrated into the Urinary Bladder and a Review of the Literature

Intrauterine contraceptive devices are being used in clinical practice since 1962. Due to their efficiency and low cost, intrauterine contraceptive devices are the most popular method of reversible contraception in developing countries. The incidence of migration of an intrauterine contraceptive device, and related uterine perforation ranges from 0.003% to 0.87%. Intrauterine contraceptive device may migrate into urinary bladder, appendix, rectum, colon, peritoneum, anterior abdominal wall or ovary. Foreign bodies like sutures, stents, and needles in the urinary bladder act as niduses for calculi formation. Intrauterine contraceptive device migrated into the bladder can also become a nidus for a stone formation. Herein we report about a case whose intrauterine contraceptive devices had migrated into the bladder, and presented with lower urinary tract symptoms and suprapubic discomfort 6 years after its insertion.
