Comparison of Transabdominal and Transvaginal Sonography in Measuring Cervical Lenghts in Midpregnancy

Abstract

Objective: To compare the transabdominal and transvaginal ultrasonographic measuring of cervical length in midtrimester of pregnancy.

Material and Methods: This retrospective study was performed in a university hospital. The pregnant women between 18-20 weeks gestation were included to the study. Transabdominal and transvaginal ultrasonographic measurement of cervical length were measured in these patients.

Results: Among 1150 pregnant women 1050 patients were included to the study. The mean maternal age, cervical lengths were 33 +/- 6.8 years and 33 +/- 5.4 years and 36.5 +/- 7.2 mm, 37.2 +/- 7.0 mm in transabdominal and transvaginal sonography group respectively. There was no significant difference between these two groups (p>0.05).

Discussion: Transabdominal measurement of cervical length may be used for the initial measurement of cervical length in low risk population.
