Aim:
The ultrasound measurement of the cervix is the gold standard for assessing the risk of preterm delivery. We compared the accuracy of this technique with measurements obtained by the cervicometer Cervilenz®. The purpose was to show that this device can be used as a screening tool, low cost, in the diagnosis of preterm labor.
Methods:
Fifty patients were included in the study at gestational age between 21+0 and 26 +0 or weeks. The study was blinded between the two performers utilizing the cervicometer and the transvaginal ultrasound.
Results:
The study showed 100% concordance and a correlation between the two techniques of 0.94.
Conclusion:
The cervicometer proved to be a reliable and easy to use device to detect a normal or short cervix, with contained healthcare costs.
