The IUD and uterine perforation

: The intrauterine device (IUD) is an effective and relatively safe contraceptive. Approximately 15% of women of child-bearing age in Italy use the IUD. The major health risks associated with IUD use are perforation of the uterus, pregnancy (both intrauterine and ectopic), and pelvic inflammatory disease. Perforation of the uterus by an IUD is a serious complication and this is possible both during the insertion and later. Perforation of the uterus is rare, but potentially fatal. The incidence is of 0.12-0.68/1000 insertion. Although some patients have signs and symptoms suggestive of perforation (pain or bleeding), many are apparently asymptomatic at the time the diagnosis of perforation is made. Perforation is often suspected or diagnosed when the IUD string is no longer visible at the external os. A patient who has sustained a perforation is not protected against pregnancy. Numerous factors affect perforation: the type of IUD, the uterine size and position, timing of the insertion in relation to the last delivery or abortion and the experience of the clinical. Serious consequences have been described, such as severe damage to the viscera (i.e. bowel, kidney) and/or peritonitis. The diagnosis is clinical, ultrasonic, radiological and coelioscopic. Coelioscopic diagnosis makes it possible to choose the method of treatment. In experienced hands, this method is rapid, the hospitalization required short and the sequelae simple.
