Accuracy of IUD placement after 2 months to 4.5 years was assessed by ultrasound compared with hysteroscopy in 58 women with a Silver T and in 39 women with Multiload 250 IUDs. Ultrasound was performed with high- resolution scanners (Ultramark 4, Diasonic DFR 100 and Acuson), immediately after menses. Hysteroscopy was done immediately after ultrasound through a HAMOU 3 hysteroscope (Storz), using carbonic anhydride for insufflation. With Silver T IUDs, there were 58 concordant findings: by ultrasound 47 were in place, 4 were descended and 7 were abnormal; by hysteroscopy there were 39 in place, 3 descended, 6 inverted, 2 incarcerated, and 3 lateral. With Multiload IUDs, there were 39 concordant findings: by ultrasound 28 were in place, 8 descended, 2 lying laterally; by hysteroscopy 28 were in place, 7 were descended and 4 were inverted. None of the women in this series had unintended pregnancy. Hysteroscopy was more accurate and also identified 6 cases of endometritis, 2 of polyps, and 2 of hyperplasia.
