Transvaginal sonography accurately predicts preterm birth risk in women treated for preterm labor. A cervical length of at least 30 mm indicates a low likelihood of premature delivery, improving diagnostic accuracy.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Diagnostic Imaging

Background:

  • Preterm labor diagnosis is crucial for timely intervention.
  • Current diagnostic methods for preterm labor may lack accuracy.
  • Transvaginal sonography offers a potential imaging-based approach.

Purpose of the Study:

  • To compare the diagnostic accuracy of transvaginal sonography with digital cervical examination.
  • To assess the utility of sonographic cervical length in predicting preterm birth after tocolysis.

Main Methods:

  • Transvaginal sonography was performed on women undergoing treatment for preterm labor.
  • Cervical length was measured sonographically; findings were not used for immediate management.
  • Sonographic cervical length was compared to digital assessment of dilation and effacement.

Main Results:

  • Cervical sonography was superior to digital assessment in predicting delivery before 36 weeks.
  • A cervical length cutoff of 30 mm demonstrated optimal sensitivity and specificity.
  • All women delivering preterm had cervical lengths <30 mm; none with lengths ≥30 mm delivered prematurely.

Conclusions:

  • Transvaginal sonography, particularly cervical length measurement, enhances preterm labor diagnosis accuracy.
  • A cervical length of at least 30 mm effectively predicts a low risk of preterm birth post-treatment.
  • Sonographic assessment can aid in identifying women unlikely to deliver prematurely.
