The Mirena IUD consists of a T-shaped polyethylene frame with a steroid reservoir around a vertical stem. The T-body is 32 mm by 32 mm (vertical and horizontal). The reservoir contains 52mg of levonorgestrel (a type of hormone) and small amounts are released daily.
While the package inserts and literature do warn about complications associated with the Mirena IUD, the patient is not warned that after the IUD is inserted it can perforate or pass through the uterus into other body parts such as the abdomen. If this occurs, it is necessary to remove the IUD through a surgical procedure such as a laparotomy.
