Objective: Cervical length (CL) examinations may identify patients in preterm labor or those who may benefit from prophylactic therapy. We sought to compare the accuracy of clinician digital CL examinations with objective measurements using the Cervilenz device in women presenting with symptoms of preterm labor.
Study Design: Forty-two patients with singleton gestation from 24 to 34 weeks' gestation and cervical dilation less than 3 cm underwent speculum examination and Cervilenz measurement. A second examiner, blinded to results, digitally measured CL. Pearson's correlation coefficient, Student t tests and McNemar's tests were used to compare digital and Cervilenz measures.
Results: Digital CL was significantly less than Cervilenz (2.88 vs 3.40 cm; P < .001), and in 36% of subjects, this difference exceeded 1 cm. The discrepancy in CL estimates persisted whether women were multiparous or had soft cervices or a history of preterm delivery.
Conclusion: Digital assessment underestimates CL, whereas the Cervilenz device permits a visualized and objective CL measure in patients with preterm labor.

Objective: A short cervix measured by transvaginal ultrasound has been correlated with increased risk for preterm delivery (PTD). Many patients presenting with a complaint of possible premature labor (PL); may not have access to cervical length (CL) screening by ultrasound. Cervilenz is an FDA cleared disposable device for obtaining vaginal CL measurements.

A short cervix in the second trimester is a powerful predictor of preterm birth risk. Multiple cervical length screens for patients in midpregnancy will likely become the standard of obstetrical care as a result of the development of effective methods (eg, cerclage, progesterone) to prevent early delivery in patients with a short cervix. Because of the high cost and infrastructure requirements, providing multiple cervical length evaluations through transvaginal ultrasound will likely be a significant barrier to universal screening.
