Hysteroscopic assessment of abnormal uterine bleeding in users of the intrauterine contraceptive device.

Sixty users of the IUD who complained of abnormal menstrual blood loss were evaluated by hysteroscopy, and the findings were compared with a matched group who had this investigation for "missing strings". Submucous fibroids and endometritis were more frequent in the study group whereas malposition of the IUD was commoner in the controls (p < 0.05).
