Abstract

OBJECTIVES: We assessed the usefulness of ultrasonography (USG) findings of adenomyosis during pregnancy in the prediction of subsequent preterm delivery. MATERIALS AND METHODS: We included consecutive pregnant women who underwent first trimester ultrasonography in our institution, confirmed as having adenomyosis and subsequently delivered in our institution from January 2006 to April 2018. The subjects were classified into two groups: preterm delivery group and term delivery group. Information of maximal uterine wall thickness measured at first trimester and second trimester, maternal characteristics, pregnancy outcomes, and neonatal outcomes were reviewed and compared between preterm and term delivery group. RESULTS: A total of 57 pregnancies were included in this study, and 14 women (24.5%) delivered before 37 weeks of pregnancy. The women from the preterm delivery group had a significantly thicker uterine wall during the second trimester of pregnancy compared to the women from the term delivery group (4.49 ± 1.62 cm vs. 3.05 ± 1.6 cm, p = 0.004). From the first trimester to the second trimester of pregnancy, uterine wall thickness showed a significantly smaller decrease in the preterm delivery group than the term delivery group (-0.42 ± 0.93 cm vs. -1.04 ± 0.89 cm, p = 0.02). By receiver operating characteristics (ROC) curve analysis, uterine wall thickness greater than 4.6 cm in the second trimester of pregnancy showed 57.1% sensitivity, 86.1% specificity, 57.1% positive predictive value (PPV) and 86.1% negative predictive value (NPV) for subsequent preterm delivery (area under curve = 0.758). CONCLUSIONS: Uterine wall thickness measurement in second trimester can help to identify preterm delivery in pregnant women with adenomyosis.
