“…However, no significant link has been found between cervix funnelling and preterm labor before week 37. 10,21,31 In our study, we used fundal pressure as a method to induce dynamic cervical changes. A large-scale study in Japan found that uterine fundal pressure maneuvers (UFPM) is used in 11.4% of total vaginal deliveries in 89.4% of perinatal medical centers Japan association of obstetricians and gynecologists, 2014.…”

“…9 Cervical ultrasounds should be utilized instead of manual evaluations, according to the findings of several research. 10,18 In both asymptomatic high-risk and low-risk women, it has been demonstrated that the evaluation of CL by ultrasonography (USG) is superior to digital examination as a predictor of preterm delivery. 11 Trans vaginal ultrasound (TVUS) is the industry leader in CL evaluation.…”

Background: Preterm labor represents one of the most likely causes for prenatal hospitalization. Previously, the accuracy of cervical length measurement in predicting preterm birth was thoroughly examined. The current study aimed to compare static and dynamic cervical assessment in prediction and management of preterm labor.Methods: The present study was prospective comparative study and conducted on (75) pregnant female patients recruited from the antenatal clinic of El-Shatby Maternity University hospital in the period from October 2021 till August 2022. The patients included in the study were divided into three groups; the first group included (25) patients and all were subjected to static cervical assessment, the second group included (25) patients and all were subjected to dynamic cervical assessment and the last group included (25) patients and all were subjected to interval dynamic cervical assessment. All groups are almost matched in their general characteristics. All groups received tocolysis in the form of nifedipine slow-release tablets 20 mg twice daily. Conventional static and dynamic transvaginal ultrasound assessment of cervical length (CL) was done.Results: There were inverse relationships between gestational age (GA), fundal level (FL) and mean gestational age (MGA) with the latency period but there was a direct relationship between the parity and the static cervical length in all the studied groups. There was a statistically significant difference between the studied groups regarding their means of latency period in those with static cervical length >1.5-2.5 cm (most of cases in all groups). Although there was statistically significant difference between group A, B and C as regard their means of static and dynamic cervical length.Conclusions: The longer the latency period, the lengthier the cervical length. The latency period had an inverse correlation with gestational age. There was also a direct relationship among parity and cervical length. The cervical estimation using the fundal pressure method, dynamic cervical length, is more enlightening than the interval approach.

“…Similar to our study, studies in the literature using various combinations of serum or vaginal biomarkers with CL measurement for prediction of preterm delivery in threatened preterm labor also performed serum biomarker measurements as early as possible at the time of diagnosis of threatened preterm birth. 48 Cervical length measurement by transvaginal sonography during evaluation for preterm labor symptoms was measured with a 4 to 10 MHz transvaginal probe (Toshiba Medical Systems Corporation, Japan) with an empty bladder. Research personnel performing transvaginal CL measurement were trained, and all images were reviewed for adequacy and accuracy using the protocol described by Iams et al at the time of image ascertainment.…”

Objective The serum ischemia modified albumin (IMA), biglycan, and decorin levels of pregnant women who were hospitalized for threatened preterm labor were measured. Methods Fifty-one consecutive pregnant women with a single pregnancy between the 24th and 36th weeks with a diagnosis of threatened preterm labor were included in the present prospective cohort study. Results As a result of multivariate logistic regression analysis for predicting preterm delivery within 24 hours, 48 hours, 7 days, 14 days, ≤ 35 gestational weeks, and ≤ 37 gestational weeks after admission, area under the curve (AUC) (95% confidence interval [CI[) values were 0.95 (0.89–1.00), 0.93 (0.86–0.99), 0.91 (0.83–0.98), 0.92 (0.85–0.99), 0.82 (0.69–0.96), and 0.89 (0.80–0.98), respectively. In the present study, IMA and biglycan levels were found to be higher and decorin levels lower in women admitted to the hospital with threatened preterm labor and who gave preterm birth within 48 hours compared with those who gave birth after 48 hours. Conclusion In pregnant women admitted to the hospital with threatened preterm labor, the prediction preterm delivery of the combined model created by adding IMA, decorin, and biglycan in addition to the TVS CL measurement was higher than the TVS CL measurement alone. Clinical trial registration The present trial was registered at ClinicalTrials.gov, number NCT04451928.

“…Several observational studies have analyzed the performance of TVS CL measurement in the prediction of PTB in symptomatic singleton pregnancy [132][133][134] . One study, encompassing more than 1000 singleton pregnancies with threatened PTL and cervical dilation < 3 cm, reported that TVS CL measurement was associated independently with the risk of PTB in both patients with closed and those with dilated cervix 133 .…”

and Gynecology (ISUOG) is a scientific organization that encourages sound clinical practice and high-quality teaching and research related to diagnostic imaging in women's healthcare. The ISUOG Clinical Standards Committee (CSC) has a remit to develop Practice Guidelines and Consensus Statements as educational recommendations that provide healthcare practitioners with a consensus-based approach, from experts, for diagnostic imaging. They are intended to reflect what is considered by ISUOG to be the best practice at the time at which they are issued. Although ISUOG has made every effort to ensure that Guidelines are accurate when issued, neither the Society nor any of its employees or members accepts liability for the consequences of any inaccurate or misleading data, opinions or statements issued by the CSC. The ISUOG CSC documents are not intended to establish a legal standard of care, because interpretation of the evidence that underpins the Guidelines may be influenced by individual circumstances, local protocol and available resources.
