Bladder calculus resulting from an intravesical translocation of intrauterine contraceptive device in a postmenopausal woman.

Although perforation of the uterus by an intrauterine contraceptive device (IUCD) is commonly encountered, intravesical translocation and secondary calculus formation is a very rare complication. We report a case of a 60-year old multiparous woman in whom an intrauterine contraceptive Copper-T device inserted 12 years earlier translocated from the uterus to the bladder and resulted in formation of a calculus. Diagnosis was established with pelvic ultrasonography and plain abdominal radiograph. The cystoscopic removal was not successful due to the large size of the calculus. The patient later underwent cystolithotomy. Sonographic follow-up immediately after the insertion and at six month intervals will go a long way in early detection of any possible complications.
