“…The only directly comparable measurement in our study was cervical dilation. We could measure cervical dilation in more than 90% of the women, which is a higher percentage than in previous studies . We believe that this high proportion was the result of all our cases having intact membranes and being in the first stage of labor.…”

“…Our findings demonstrate that there is a strong agreement in the decision to admit singleton pregnant women at term due to labor based on ultrasound measurements or digital vaginal examination. Measurements of cervical dilation are easily obtained by ultrasound and high concordance between observers has been demonstrated . Making decisions based on ultrasound and symptomatology instead of digital vaginal examination could result in a significant reduction in the number of digital vaginal examinations.…”

“…The main weakness of our study is the lack of interobserver verification of the digital vaginal examinations and ultrasound measurements. Although sonographic measurements are highly reproducible and reliable, it would have been useful if they had been performed by two independent operators in addition to the digital vaginal examination …”

Introduction The aim of this study was to test the hypothesis that transperineal ultrasound can be used to decide whether to admit a pregnant woman due to labor. Material and methods In this analytical cross‐sectional observational study, transperineal ultrasound was performed on pregnant women with intact membranes who came to the hospital due to contractions. A decision was made to admit women due to labor based on the ultrasound measurements. The ultrasound measurements were used to determine cervical dilation, the angle of progression, and fetal head position. The managing midwives were blinded to the results and made the final decision to admit the women based on digital vaginal examination. Results It was possible to decide whether a woman had to be admitted for delivery or discharged due to the latent phase of labor according to the ultrasound examination in 55 of the 57 cases (96.5%). In four of the 55 cases, the decision based on ultrasound differed from the midwife's decision (7.3%). There was strong agreement between the decision to admit the pregnant women based on ultrasound measurements and the digital vaginal examination (Cohen's kappa: 0.844). It was possible to measure cervical dilation with ultrasound in 52 of the 57 cases (91.2%). The intraclass correlation coefficient for the cervical dilation measurements was 0.736 (95% confidence interval 0.539‐0.848). Conclusions There was strong agreement between the ultrasound and digital vaginal examination results in the decision to admit singleton pregnant women at term due to labor. A large number of vaginal examinations could be avoided by using intrapartum ultrasound.

“…2 Because digital examination of cervical dilatation and transperineal ultrasound measurements are compatible with each other and transperineal ultrasound is less invasive and has a very good repeatability for women. 7,8 Authors used the following measurements on transperineal ultrasound to detect whether it is useful to predict vaginal delivery: HPD, head-pubis distance and AOP. The angle greater than 120º-126º was associated with vaginal delivery in many publications.…”

Background: Digital cervical evaluation has been used to determine the likelihood of vaginal delivery which is considered by many women to be non-tolerable. Recently, transperineal ultrasound allowing direct visualization of the fetal skull has been using for the prediction of labor route. Authors aimed to study whether measurements on transperineal ultrasound are predictive for vaginal delivery in pregnant women induced with dinoprostone at 40.0-42.0 gestational weeks.Methods: A total of 55 pregnant women at 40.0-42.0 gestational weeks were enrolled in this prospective observational study. All participated women were examined before the induction with dinoprostone to measure the head-perineum distance (HPD), the head-pubis distance and the angle of progression of fetal head (AOP).Results: The greater AOP, the shorter HPD and the head-pubis distance were associated with vaginal delivery in the nulliparous women. The HPD and the head-pubis distance were shorter, whereas the AOP was greater in the multiparous women giving birth by vaginal route.Conclusions: Transperineal ultrasound can be applied at the beginning of labor to predict whether vaginal delivery will occur or not. As shown in our study, the pregnant women with shorter HPD and wider AOP might have a high possibility to achieve vaginal delivery.

Introduction: there are various options for the application of an ultrasound transducer in transperineal sonography procedure (TPUS), starting from percutaneous scanning of the perineum area by sector transducers and ending with the use of transalabial (TLUS), transvaginal (TVUS) and transrectal access by the intracavitary transducers. In all these cases, it is necessary to identify the relationships of pelvic organs. The ultrasonic technique of the “three tracks” (TTT) allows real-time evaluation of the spatial ratio of the urethra, vagina and rectum, as well as adjacent subjects of the pelvis, visualizing them simultaneously in the same scanning plane.Objective: to present the “three track» technique used in the conduct of translabial ultrasonography, and to study the results of revealing the pathology in lower pelvis in comparison with routine transvaginal ultrasonography (TVUS).Participants, settings, methods: the study was conducted between January 18, 2016 and November 27, 2017 in the clinic for reproductive medicine “Remedi” (Odesa). Informed consent to the investigation was obtained from all females. 70 patients of the main group underwent translabial ultrasonography in the “three track” technique (TLUS + TTT). 71 women of comparative group underwent a routine transvaginal ultrasonography.Results and discussion: visualization of three tracks: urethra, vagina and rectum in one scan plane was achieved in 65 patients of the main group (93%). In addition, in the main group, approximately twice as often as in the comparison group, a rare pathology of the lower pelvis, such as Gartner duct cysts, the Bartolin cysts, the deep endometriosis of the rectovaginal septum and unclassified cysts of the vagina, were found. However, the insufficient number of obtained results does not allow confirming their reliability.Conclusion: the using of TTT during TLUS, extends the diagnostic opportunities of the examiner in the evaluation of the relationship of adjacent organs and tissues in the pelvic floor and lower pelvis. The method requires further research and can be used as an additional bonus to improve for accuracy and safety of diagnostic and surgical gynecological practice.There is no conflict of interest to declare.
