Core Tip

Core Tip: Levonorgestrel-releasing intrauterine systems (LNG-IUS) is the effective against hypermenorrhea and dysmenorrhea. In many cases, like previous devices, we misunderstand that the device can be recognized by ultrasound. In this case, the diagnosis was that there was no device in the uterus, however, there were two devices that were displaced and caused myometrium damage. Plain abdominal X-ray is important to confirm the position of LNG-IUS.
