Abstract:
Migration of an intrauterine contraceptive device (IUCD) into the bladder and secondary stone formation are uncommon complications associated with the insertion of IUCD. To our knowledge, there have been no such reported cases in Japan. In the present report, we describe the case of a 59-year-old woman who underwent an operation for the removal of an IUCD from the bladder, which had been inserted 30 years ago. The patient was referred to our facility because of hematuria and recurrent urinary tract infections. A plain film revealed a calcified mass in the pelvis, and cystoscopy revealed a fully mobile calculus in the bladder. During a transurethral cystolithotripsy, the IUCD was found within the calculus and removed transurethrally. No fistulae or defects were found in the bladder wall.
