Evaluation of Transperineal Ultrasound Technic for Diagnostic Shorted Cervical Length for Pregnant Women (2nd and 3rd Trimester) Compared to Endovaginal Technic (Gold Standard)

The cervical length is a crucial part of the diagnostic of premature labor. The gold standard technic is the endovaginal ultrasound. This is a technic with good reproducibility and good precision. Some authors have found the transperineal technic to present the same characteristics, without being as invasive. The aim of the study was to compare the results of the less invasive technic to the current invasive gold standard in pregnant women who consult for contraction, or for whom cervical modification is suspected in order to determine whether the former could replace the latter.
