BACKGROUND: The prevalence of congenital uterine anomalies in women with reproductive failure remains unclear, largely due to methodological bias. The aim of this review is to assess the diagnostic accuracy of different methodologies and estimate the prevalence of congenital uterine anomalies in women with infertility and recurrent miscarriage ( RM). METHODS: Studies from 1950 to 2007 were identified through a MEDLINE search; all relevant references were further reviewed. RESULTS: The most accurate diagnostic procedures are combined hysteroscopy and laparoscopy, sonohysterography ( SHG) and possibly three-dimensional ultrasound (3D US). Two-dimensional ultrasound ( 2D US) and hysterosalpingography (HSG) are less accurate and are thus inadequate for diagnostic purposes. Preliminary studies ( n = 24) suggest magnetic resonance imaging ( MRI) is a relatively sensitive tool. A critical analysis of studies suggests that the prevalence of congenital uterine anomalies is similar to 6.7% [ 95% confidence interval (CI), 6.0 - 7.4] in the general population, similar to 7.3% ( 95% CI, 6.7-7.9) in the infertile population and similar to 16.7% ( 95% CI, 14.8 - 18.6) in theRMpopulation. The arcuate uterus is the commonest anomaly in the general and RM population. In contrast, the septate uterus is the commonest anomaly in the infertile population, suggesting a possible association. CONCLUSIONS: Women with RM have a high prevalence of congenital uterine anomalies and should be thoroughly investigated. HSG and/or 2D US can be used as an initial screening tool. Combined hysteroscopy and laparoscopy, SHG and 3D US can be used for a definitive diagnosis. The accuracy and practicality of MRI remains unclear.
