Pregnancy and its outcome in women with malformed uterus.

OBJECTIVE

To analyze the clinical characteristics of fertility and pregnancy in women with congenital uterine malformations and explore optimal treatments to improve the prognosis.

METHODS

A retrospective study was conducted on the fertility and obstetric outcome in 153 patients with uterine malformations treated in our hospital from January 1984 to December 1998. Twenty-seven cases with other kinds of genital and/or urinary anomalies but with normal uterus during the same period were enrolled as the control group.

RESULTS

The infertility rate was 26.6% (34/128), the miscarriage rate 44.3% (86/194), premature birth rate 9.3% (18/194), abnormal fetal presentation rate 28.4% (29/102), the cesarean section rate 61.8% (63/102), and the perinatal mortality rate 11.8% (12/102).

CONCLUSION

Women with congenital uterine malformation usually have higher incidence of infertility and complications during pregnancy and delivery. Bicornuate and septate uterus can be associated with poor obstetric outcome.
