Objective. The purpose of this presentation is to familiarize physicians about the different types of intrauterine devices (IUDs) used in China. Methods. The characteristic features and the sonographic appearances of the different types of IUDs commonly used in China are described. Results. The stainless steel ring is the most commonly used IUD in China. However, various different types of copper‐bearing IUDs are gaining popularity. Most Chinese IUDs do not have an attached thread and are more difficult to remove than the IUDs commonly used in North America. Also, most Chinese IUDs have a distinct sonographic appearance; therefore, sonography can play an important role when assessing a woman who has a retained Chinese IUD or has a complication associated with the IUD. Conclusions. Knowledge about the different types of Chinese IUDs will enable physicians to provide optimal care to their patients.
