異所性子宮内避妊具：集学的アプローチ

Implantation of intrauterine contraceptive devices (IUCDs) has become a common method of family planning. Very few patients experience any complication, which is why it is regarded as a safe method. However, here we present a case in which a calcified intrauterine contraceptive device (IUCD) was seen in the bladder. This intrauterine device had been placed 11 years ago, and the patient had also delivered a healthy baby during this time. It was removed successfully by surgery without injury to the bladder or surrounding structures. The recovery remained uneventful with strict monitoring of the patient. She was discharged on the seventh postoperative day. This report highlights the significance of early diagnosis and management of lost intrauterine device (IUCD) to prevent complications and mismanagement.
