Abstract

Background: Preterm birth is the leading cause of perinatal morbidity and mortality
worldwide.
The objectives of the present study were:1) the role of transvaginal
ultrasonographyassessment of cervical length measurement, internal os diameter, funneling
of internal os in predicting preterm labor among antenatal women with risk of preterm
labor.2) neonatal outcome of the study population
Methods:A hospital based prospective study was carried out on 100 antenatal women
attending antenatal OP and emergency room at risk of preterm labor over a period of 1 year
from 2018-2019 and subjecting them to transvaginal ultrasound in assessing cervical length
and cervical dilatation. The cases were then followed till delivery.
Results: Prediction of preterm labor with cervical length less than 25mm by transvaginal
ultrasound was taken as a measure of diagnostic efficacy .Cervical length less than 25 mm
had a sensitivity of 48.08% (34.01%- 62.37%), specificity of 91.67% (80.02% -97.68%),
positive predictive value of 86.21% (70.11% - 94.3%) and negative predictive value of
61.97% (55.31% - 68.21%) in predicting preterm labor.
Conclusion:Transvaginal ultrasound is an efficient and reliable diagnostic tool to predict
antenatal women with risk of preterm labor
