Ultrasound screening for congenital uterine anomalies.

The aim of this study was to investigate the prevalence of congenital uterine anomalies in 1046 women attending gynaecological ultrasound clinics for a variety of indications. Using three-dimensional ultrasound, anomalies were found in 55 women (5.4%), including 32 (3.1%) with an arcuate uterus and 23 (2.3%) with major anomalies. The prevalence of uterine anomalies was similar to the findings in women undergoing elective sterilisation, but lower than in studies of women with recurrent miscarriage.
