AIM: We aimed to evaluate the effectiveness and usability of the uterocervical angle, which we examined ultrasonographically before misoprostol treatment, which we used in first-trimester pregnancy terminations, and its relationship with the abortion time. METHOD: This prospective study includes 207 pregnant women diagnosed with an ex-fetus in utero hospitalized for medical termination in a single center. These patients were divided into two groups patients whose treatment was completed in the first cycle and who needed additional cycles. The characteristics of all pregnant women, abortion times, and misoprostol doses used were compared with uterocervical angle and cervical length and analyzed between groups. RESULTS: The mean age of the patients in the entire study group was 30.1±6.3, the median uterocervical angle was 112 degrees, and the cervical length was 36 mm. Increasing cesarean number and increasing uterocervical angle degree were positively correlated with increasing abortion time. The number of cesarean sections and the degree of uterocervical angle differ significantly between the group whose treatment was completed in the first cycle and the groups that needed additional cycles. In the treatment groups with elevated uterocervical angle degrees, the first cycle was higher than the successful group. Additional dose and cycle requirements arise if the uterocervical angle is >110 degrees. CONCLUSION: Evaluation of the uterocervical angle in first-trimester medical terminations may guide the clinician in the early completion of treatment. With this evaluation before medical treatment, the duration of hospitalization can be shortened, and the need for surgical intervention for patients can be reduced.

“…The cervical length is the most commonly used ultrasonographically used parameter that gives information about the cervix. However, in recent years, the angle measurement between the lower uterine segment and the cervical canal has become popular in many subjects, especially in predicting birth and preterm labor (16,19).…”

“…Until now, UCA measurements were performed in the following studies for three purposes: (a) screening in the mid‐trimester between 14 and 24 weeks gestation for PTB prediction 12,13,15–17 ; (b) screening in late pregnancy after 37 weeks gestation for differentiation between false and early true labor 14 ; and (c) in prediction for second‐trimester pregnancy termination duration 23 . Performance of UCA and CL measurements with relation to preterm delivery and the time interval until delivery in patients with contractions was another issue addressed in our study and showed significance for gestational age, CL, and UCA.…”

ObjectivesThe aim of this study was to evaluate the relationship between the cervix and the threat of preterm labor in singleton pregnancies between gestational weeks less than 37 and greater than 37 weeks in correlation with utero‐cervical angle (UCA) and cervical length (CL) measurements.Materials and MethodsWe conducted a prospective cohort study with UCA and CL measurements in patients with threatened preterm labor (TPL). Primary outcome was differences in UCA and CL measurements in relationship to maternal characteristics and perinatal outcome between groups. Secondary outcome evaluated measurement results and influencing factors for delivery within 7 days, between 1 and 4 weeks and beyond 4 weeks.ResultsOverall 152 patients were divided into as study/preterm group (<37 weeks; n = 56) and the control/term group (≥37 weeks; n = 96). Mean gestational age at admission was similar in both groups (30.98 ± 2.83 vs. 30.36 ± 2.63 weeks, p = 0.149) with similar CL (33.9 ± 6.34 vs. 32.02 ± 8.88 mm, p = 0.132), but wider UCA in the preterm group (81.65 ± 16.81° vs. 99.21 ± 22.33°, p < 0.001). Multivariate logistic regression analysis for preterm delivery was significant for nulliparity and UCA measurement. The factor for delivering before 37 gestational weeks within 7 days was the gestational week at admission (p = 0.046). UCA and CL measurements were statistically significant for distinguishing patients for delivery within 7 days and beyond 4 weeks (p = 0.001 for CL and p = 0.0001 for UCA). NPV was found 92.5, 92.2, and 92.3 for UCA >105°, CL ≤30 mm, and Bishop score >3, respectively.ConclusionCombined measurement of TV UCA and CL represents stronger predictors for sPTB ultrasonographically, demonstrating the uterocervical sub‐segment maturation before the active onset of labor.

Introduction Uterocervical angle measurements in pregnant women with idiopathic polyhydramnios were appraised for their predictive value for spontaneous preterm labor. Material and Methods In this prospective study, we included nulliparous and multiparous pregnant women diagnosed with idiopathic polyhydramnios at 24?28 weeks at our polyclinic; the uterocervical angle and cervical length were measured by transvaginal ultrasound at the time of diagnosis. Routine pregnancy follow-up was done by our team and gestational age at delivery and maternal-fetal outcomes were noted. Results In total, 24 patients delivered before 37 weeks and 36 patients delivered at 37 weeks or later. Preterm labor subjects had larger UCA values (126.7?12.9? vs. 100.8?16.2?) and term labor patients had larger cervical length values (34.3?4.5 mm vs. 40.6?5.2 mm). In women with idiopathic polyhydramnios, the area under the curve for the uterocervical angle was 0.885 (p<0.001) and it was 0.823 for the cervical length (p<0.001). Discussion The uterocervical angle, a sagittal transvaginal cervical image measurement, is a practical method that successfully predicts spontaneous preterm labor risk in singleton pregnancies with idiopathic polyhydramnios. In addition, the uterocervical angle displayed greater sensitivity, but lower specificity, compared with cervical length measures.

The efficiency of the uterocervical angle in the prediction of second-trimester pregnancy terminations in multiparous women

Abstract: The UCA is broader in multiparous women who successfully terminated and is linked to a shorter duration of induction. The UCA by itself is the only significant contributor to the outcome of second trimester pregnancy terminations.
