Efficacy and Safety of Ultrasound Guided versus Blind Technique for Office Insertion of Intrauterine Contraceptive Device: A Randomised Clinical Trial

Abstract

ABSTRACT IUDs are highly, if not the most effective method of contraception with typical use related failure rates of between 0.2-0.8%. Difficulties with IUD insertion, failure and complications can lead to decreasing utilization of such an effective method. The intrauterine position of an intrauterine contraceptive device is thought to be closely related to its contraceptive power. In the first year after insertion, between 5 and 15% of women will have their IUD removed because of irregular uterine bleeding which have been attributed to the effect of contact between the device and the endometrium and even the pressure on the uterine muscle. The disharmonious relationship between the IUD and the uterus is the cause of most of the bleeding complaints, so bleeding is related to improper position rather than the contraceptive method itself which should be excluded before abandoning the IUD for any other method of birth control.
