Abstract
OBJECTIVE: The aim of the study was to evaluate reproductive performance of women with didelphic uterus and to consider possible long-term consequences associated with this uterine anomaly. STUDY DESIGN: Forty-nine women were diagnosed as having a didelphic uterus with a longitudinal vaginal septum at Tampere University Hospital, Finland between 1962 and 1998. The presence of other anomalies, gynecologic disorders, fertility and outcome of pregnancies were reviewed. The long-term clinical implications associated with a didelphic uterus were evaluated during the mean (S.D.) follow-up period of 9.1 (6.3) years. RESULTS: An obstructed hemivagina was found in nine (18%) out of forty-nine cases; eight of these had ipsilateral renal agenesis. A longitudinal vaginal septum was excised in twenty-six (53%) cases, but metroplasty in none. Five (13%) patients had primary infertility. Thirty-four (94%) out of thirty-six women who wanted to conceive had at least one pregnancy, and they produced seventy-one pregnancies; 21% miscarried, and ectopic pregnancy occurred in 2%. The fetal survival rate was 75%, prematurity 24%, fetal growth retardation 11%, perinatal mortality 5. 3%, and cesarean section rate 84%. Pregnancy located more commonly (76%) in the right uterus than in the left. During the follow-up period endometriosis was observed in seven (16%) out of forty-five cases. Ovarian neoplasm was found in four (9%) cases, one of them had ovarian cancer. CONCLUSIONS: Fertility in women with didelphic uterus is not notably impaired. The prognosis of pregnancy is comparatively good, while prematurity and fetal growth retardation indicate meticulous prenatal care. Long-term follow-up did not reveal that didelphic uterus is associated with increased frequency of endometriosis or genital neoplasm.
