Sonographically, cervical length measurement is widely used in obstetrics. Studies have revealed that early detection of short cervix can be a predictor of predicting preterm labor. Transvaginal ultrasonography has been shown as a reference method for the recognition of the short cervix, as well as it may be useful in the transabdominal evaluation in the studies conducted. In addition to the advantages of transvaginal evaluation, it is time consuming and disadvantages of some women during anxiety and discomfort during this procedure. Transabdominal ultrasonography, which provides a non-invasive evaluation, is more preferred by some patients than transvaginal. The aim of this study is to investigate the value of the cervical length measured by transabdominal route, which is a more acceptable method for pregnant women, in predicting preterm birth.

Births that occur before 37th gestational week are an important cause of perinatal morbidity and mortality. Preterm birth accounts for about 12% of all births. Early screening and correct management of pregnant women at risk of preterm birth is essential in reducing perinatal mortality and morbidity associated with prematurity. But the precise prediction and prevention of preterm birth is still an important research topic.
