Uterus didelphys: a report of 26 cases.

Twenty-six female patients with uterus didelphys were observed over a period of 21 yr. All the patients also had a longitudinal vaginal septum. Dysmenorrhea, dyspareunia and leukorrhea were the most common symptoms among the symptomatic cases. Eighteen women had a total of 40 pregnancies with a fetal survival rate of 67.5%, and perinatal mortality rate of 3.6%. Premature delivery occurred in 21% of the pregnancies. Breech presentation occurred in 43% and cesarean section was performed in 82% of the cases. Of the 17 intravenous pyelograms performed six (35%) showed abnormalities and four had the absence of a kidney. Women with uterus didelphys belong to a high-risk group, although pregnancy outcome is comparatively good.
