Not every subseptate uterus requires surgical correction to reduce poor reproductive outcome.

OBJECTIVE

To evaluate whether hysteroscopic septoplasty should be performed in all women diagnosed with subseptate uterus.

METHODS

In a prospective study, 138 patients diagnosed with subseptate uterus at the First Affiliated Hospital of Guangxi Medical University, Nanning, China, were enrolled between January 1, 2006, and March 1, 2011, and reproductive outcomes were compared among women who did and those who did not undergo hysteroscopic resection. Women were divided in 2 groups: group A comprised women with a history of recurrent spontaneous abortion (RSA), and was subdivided into control (A1) and surgery (A2) groups; group B comprised women with no history of poor reproductive outcomes, and was subdivided into control (B1) and surgery (B2) groups.

RESULTS

The rates of pregnancy and term delivery were higher in group A2 than in group A1 (P<0.05). The incidence of RSA and preterm delivery was higher in group A1 than in group A2 (P<0.05). There was no difference in pregnancy rate, incidence of RSA, or preterm or term delivery between group B1 and group B2.

CONCLUSION

Hysteroscopic septoplasty significantly improved pregnancy outcomes in women with a history of RSA, but did not influence reproductive outcomes in women with no history of poor pregnancy outcomes.
