Significance of ultrasound vaginal cervicometry in predicting preterm delivery.

Background: The objective of the study was to verify whether ultrasound vaginal cervicometry, performed in the 18th-20th week of gestation, can effectively predict preterm delivery.

Material/methods: 279 singleton pregnancies were prospectively studied from the middle of gestation until delivery. In the 18th-20th week of gestation we performed ultrasound vaginal cervicometry, which we used to determine the length of the cervix, judge the shape of the internal os, and evaluate the cervicometry as normal or abnormal on the basis of these parameters.
