A study designed to monitor uterine placement of IUDs inserted immediately postpartum using echosonography was conducted at the Hospital de Gineco Obstetricia No. 23, "Dr. Ignacio Morones Prieto" in Monterrey, Mexico. TCu220 and Delta T IUDs were randomly assigned to, and inserted in women immediately following a normal vaginal delivery. Ultrasound examinations were to be performed within 60 min postinsertion, at 24 h postinsertion and at 1- and 3-month follow-up visits. There were no differences in the expulsion rates of the two device groups. Data are presented on the readings taken at the ultrasound examinations of the distance between the fundus and the upper part of the stem of the T. These differences differed significantly between the two device groups at the first ultrasound reading only (P less than or equal to 0.01). No relationship was found between the incidence of expulsion and the distance between the IUD and the fundus at any of the readings.

These differences differed significantly between the 2 device groups at the 1st ultrasound reading only.
