Müllerian anomalies: a proposed classification. (An analysis of 144 cases).

Hospital and clinic charts for 100 patients with diagnosed Müllerian anomalies were reviewed. Reproductive history, type of therapy, and treatment results for those patients and for another 44 with a history of exposure to diethylstilbestrol and abnormal hysterosalpingographic findings were recorded and evaluated. The anomaly most frequently associated with reproductive failure was the septate uterus. A new classification, based on degree of failure of normal development, was used in separating the anomalies into groups with similar clinical manifestations, treatment, and prognosis for fetal salvage.
