It's been 100 years since the first intrauterine device (IUD) was invented in Germany in 1920. IUDS are widely favored by women of childbearing age for their efficiency, convenience, cheapness, and variety of materials. According to incomplete statistics, about 26 million people worldwide will need to have their IUDS removed from 2015 to 2025 alone. With such a large case base, we have to pay attention to the safety of IUD removal. There are few international guidelines on IUD placement and removal. Therefore, this paper will report a case of uterine artery rupture caused by ring removal, and discuss the important steps of ring removal surgery, so as to enhance the attention of physicians to the standard and safety of ring removal and improve the quality of medical treatment.
