Comparison of transabdominal and transvaginal sonography in measuring cervical lenghts in midpregnancy

Abstract

Comparison of transabdominal and transvaginal sonography in measuring cervical lenghts in midpregnancy 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.
