OBJECTIVE To examine the potential value of routine measurement of cervical length in singleton pregnancies at 23 weeks of gestation in the prediction of the risk for early spontaneous preterm delivery. METHODS Cervical length was measured by sonography at 23 weeks in 2567 singleton pregnancies in women attending for routine antenatal care. In 43 women, the length was < or = 15 mm and 21 of t...

Background Preterm labor and birth are associated with several neonatal complications including respiratory distress syndrome and intraventricular hemorrhage. Differentiating true and false labor pain is a dilemma to obstetricians. Objective To elucidate the role of cervical length measurement in prediction of birth in pregnant women with threatened preterm labor. Materials and Methods In t...

OBJECTIVES To estimate the ability of cervical length measured by transvaginal ultrasonography in asymptomatic high-risk women to predict spontaneous preterm birth. METHODS MEDLINE, PubMed, EMBASE and the Cochrane Library were searched for articles published in any language between January 1980 and July 2006, using the keywords 'transvaginal ultrasonography' or ('cervix' and ('ultrasound' or ...

OBJECTIVE To assess the efficacy of the cervical phosphorylated insulin-like growth factor binding protein-1 (pIGFBP-1) in combination with cervical length measurement for the prediction of preterm delivery. DESIGN Observational prospective study. SETTING University Hospital, Spain. SAMPLE A total of 276 women between 24 and 34 weeks gestational age complaining of uterine contractions and...

OBJECTIVE To determine what constitutes normal cervical changes during the second half of pregnancy in parous women delivering at term. DESIGN The study comprises 21 healthy, pregnant parous women who all gave birth at term. They were examined with transvaginal ultrasound every two weeks from 24 gestational weeks until delivery. Cervical length and width were measured. The inner cervical os w...

OBJECTIVE To examine the potential value of routine measurement of cervical length in singleton low-risk pregnancies at 37 weeks of gestation in the prediction of onset and outcome of labor. METHODS Cervical length was measured by transvaginal sonography at 37 weeks in 1571 singleton low-risk pregnancies. Outcome measures were gestation at spontaneous onset of labor, post-term delivery, durat...

Background Predicting preterm delivery can help obstetricians and midwives for better management of pregnancy care. Therefore, we aimed to investigate the relationship between cervical length and uteroservical angle with the occurrence of preterm delivery. Materials and Methods: The present cohort study was conducted on 100 pregnan...

OBJECTIVE To compare the success rates and gestational ages at delivery of nifedipine administration as a tocolytic agent to pregnant women with threatened preterm labor based on cervical length. MATERIAL AND METHOD One hundred eighty eight pregnant women with threatened preterm labor between 26 and 35 weeks were enrolled in the present study. Cervical measurement was performed in all patient...

OBJECTIVE To determine whether the degree of cervical lengthening after cerclage and whether serial follow-up measurements of cervical length after cerclage are predictive of pregnancy outcome. METHODS Eighty women whose primary physician determined that a prophylactic (n = 50) or urgent cerclage (n = 30) was indicated had transvaginal ultrasonographic evaluation before and after cerclage. Th...

OBJECTIVE To determine whether short cervical lengths (≤20 mm) that were initially detected in mid-trimester and early in the third trimester are independently associated with increased risks of subsequent histologic chorioamnionitis and spontaneous preterm birth (SPTB, defined as a delivery before 34 weeks) in asymptomatic women with twin pregnancies. MATERIAL AND METHODS This is a prospecti...
