[Uterine perforation and vesical migration of an intrauterine device. Case observation].

PIP: A case of uterine perforation, caused by a TCu 200 IUD which emigrated to the urinary bladder, is reported. It was extracted by transuretral endoscopy after term pregnancy and delivery. Such accidents are rare, but according to the literature are more frequent with some devices like the Birnberg Bow than with others such as Lippes Loops. Certain factors contributing to the possibility of perforation are inept insertion or positioning, fragility of the uterine wall due to recent birth or abortion, or pregnancy. Symptoms may be nonexistent. Conversely, it can cause severe pain or problems like intestinal obstruction or uterine lesion.^ieng
