“…Eleven studies all conducted on the second trimester UCA as well as its association with sPTB were included in this study [12-14, 17-24], with a total of 5,061 patients (4,511 Singleton and 550 twin). Of these studies, 6 were prospective [12, 14, 17, 20, 23, 24] and 5 were retrospective studies [13, 18, 19, 21, 22]. Except one study [23], all UCA measurements were performed transvaginally in other studies.…”

“…Except one study [23], all UCA measurements were performed transvaginally in other studies. Notable, all these studies were published between 2016 and 2020, and 3 studies were conducted in the USA [19, 21, 22], 3 in Spain [13, 18, 20], one in Turkey [17], one in China [23], one in Chile [14], one in Thailand [12], and one in India [24]. The characteristics of these eleven included articles with more details are shown in Table 1.…”

“…Thus, a number of studies have assessed the UCA predictive value, mostly measured at the 2nd trimester, at the same time with CL screening, for early identification of women at risk for sPTB. However, their findings seem to be conflicting [12][13][14].…”

The Novel Ultrasonographic Marker of Uterocervical Angle for Prediction of Spontaneous Preterm Birth in Singleton and Twin Pregnancies: A Systematic Review and Meta-Analysis

The alteration of the uterocervical angle (UCA) has been proposed to play an important role in spontaneous preterm birth (sPTB). The aim of this systematic review and meta-analysis was to evaluate the evidence on the UCA predictive role in sPTB. In this study, PubMed, Web of Science, Scopus, and Google scholar were systematically searched from inception up to June 2020. Inter-study heterogeneity was also assessed using Cochrane’s Q test and the I2 statistic. Afterward, the random-effects model was used to pool the weighted mean differences (WMDs) and the corresponding 95% confidence intervals (CIs). Eleven articles that reported second-trimester UCA of 5,061 pregnancies were included in this study. Our meta-analysis results indicate that a wider UCA significantly increases the risk of sPTB in following cases: all pregnancies (WMD = 15.25, 95% CI: 11.78–18.72, p < 0.001; I2 = 75.9%, p < 0.001), singleton (WMD = 14.43, 95% CI: 8.79–20.06, p < 0.001; I2 = 82.4%, p < 0.001), and twin pregnancies (WMD = 15.14, 95% CI: 13.42–16.87, p < 0.001; I2 = 0.0%, p = 0.464). A wider ultrasound-measured UCA in the second trimester seems to be associated with the increased risk of sPTB in both singleton and twin pregnancies, which reinforces the clinical evidence that UCA has the potential to be used as a predictive marker of sPTB.

“…During the last years several studies investigated the potential impact of UCA for the prediction of preterm birth. The rationale behind the hypothesis of this association is based on the potential mechanical properties of this angle, which seems to act as a preventive barrier when it is acute [12] . However, there is a scarcity in the published literature which determine whether the UCA correlates with the risk of spontaneous preterm birth PTB.…”

Aim: This study aimed to determine whether a novel ultrasonographic marker, uterocervical angle, correlates with risk of spontaneous preterm birth. Materials and Methods: In the present prospective, cohort, study, we included 197 singleton pregnant women at Ain shams university maternity hospital (outpatient obstetrics clinics and emergency department. The mean age of the included women was 27.2 ± 4.8 years while the mean party was 2.2 ±1.3. The mean BMI was 33.4 ± 2.6Kg/m2. Results: In the present study, we found that there were statistically significant differences between both groups in terms of history of preterm labor (p <0.001) and tobacco smoking (p =0.008). Smokers and women with history of PTB had higher risk of PTB. In our report, there were statistically significant differences between both groups in terms of neonatal mortality. With regard to the primary outcome of the present study, we found that there was statistically significant difference between women with spontaneous preterm labor and women with term deliveries regarding UCA (p =0.015). Mean UCA in the second trimester was wider in the preterm group compared with the control group. The UCA was a significant discriminator of preterm labor. At cut-off value of ≥ 105, the GP37 yielded a sensitivity of 86.7% and specificity of 89% for the discrimination between preterm and term deliveries. Conclusion:Wider UCA in the second trimester is related to spontaneous PTB. UCA measurement is a reproducible technique. UCA appears to increase from the first to the second trimester.

“…Otra investigación halló que el valor de la COR era de 0,704 y el valor de corte optimo era de 110º, con sensibilidad de 83% y valor predictivo positivo de 16%. Los autores llegaron a la conclusión que la medición durante el segundo trimestre no era un bien predictor de PP (24) . Este es el primer estudio que compara directamente la capacidad pronóstica del AUC y la LC en la predicción de PP pacientes sintomáticas.…”

Objetivo. Comparar el ángulo uterocervical con la longitud cervical en la predicción de parto pretérmino inminente en pacientes sintomáticas. Diseño. Estudio de casoscontroles. Institución. Hospital Central “Dr. Urquinaona”, Maracaibo, Venezuela. Participantes. Pacientes con parto pretérmino en los siguientes 7 días (grupo A) y embarazadas con parto pretérmino más allá de los 7 días (grupo B). Métodos. Al momento del diagnóstico, las pacientes fueron evaluadas utilizando ecografía transvaginal y fueron seguidas hasta el parto. Principales medidas de resultado. Características generales, ángulo uterocervical, longitud cervical, parto pretérmino inminente y eficacia pronóstica. Resultados. Se incluyó 326 pacientes: 75 mujeres presentaron parto pretérmino inminente (grupo A) y 251 pacientes fueron consideradas como controles (grupo B). Las pacientes del grupo A presentaron valores significativamente más altos del ángulo uterocervical y más bajos de longitud cervical comparado con las pacientes del grupo B (p < 0,0001). El ángulo uterocervical mostró un valor de área bajo la curva de 0,864, mientras que el valor del área bajo la curva de la longitud cervical fue 0,985. La diferencia de la capacidad de discriminación entre las áreas bajo la curva de cada prueba fue significativa (p < 0,0001). Conclusión. El ángulo uterocervical no es superior a la longitud cervical en la predicción de parto pretérmino inminente en pacientes sintomáticas.
