Uterine anomalies and pregnancy outcome following resectoscope metroplasty.

OBJECTIVE

To compare reproductive outcome in women with uterine anomalies and women with a normal uterus, and evaluate the effect of resectoscope metroplasty.

METHODS

The pregnancy outcomes, past and present, of 105 women with congenital uterine anomalies were compared with those of 182 women with a normally shaped uterus. The outcomes of 25 women with septate and bicornuate uteri before and after resectoscope metroplasty were also analyzed. The chi(2) and Mann-Whitney U test were used for statistical analysis, with P<0.05 considered statistically significant.

RESULTS

Uterine anomalies were associated with higher rates of spontaneous abortion, preterm delivery, intrauterine growth retardation, breech presentation, and cesarean delivery (P<0.001). The highest incidence of early spontaneous abortion was noted among women with septate uteri, and the highest incidence of preterm labor was noted among women with arcuate or bicornuate uteri. Among women with arcuate uteri, significantly lower gestational age and birth-weight were observed compared with any other type of adverse outcome. Compared with their previous pregnancies, the abortion rates were lower and delivery rates were higher in women who conceived following hysteroscopic metroplasty (P<0.001).

CONCLUSION

Resesctoscope metroplasty significantly improved pregnancy outcome in women with uterine anomalies.
