“…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 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.

“…The UCA has been frequently evaluated in recent years along with cervical length in predicting preterm labor, particularly in obstetrics (Benito Vielba et al, 2020; Daskalakis et al, 2018; Draper et al, 2000; Farràs Llobet et al, 2018; Farràs Llobet et al, 2020; McGregor et al, 1994). Luechathananon et al reported that a UCA of >110° indicated preterm delivery with a sensitivity of 65.1% and a specificity of 43.6% in pregnant women with threatened preterm labor (Luechathananon et al, 2021.…”

The effect of anterior uterocervical angle and cervical length on the development of pelvic inflammatory disease

et al. 2022

This study aims to compare the uterine body longitudinal axis, uterine body transverse axis, uterine cervix longitudinal axis and anterior cervical axis angle measured ultrasonographically between women with pelvic inflammatory disease (PID) and healthy controls. Women aged 18-45 years with PID and healthy controls were included in the study. Demographic characteristics, uterine body long axis, uterine body transverse axis, uterine cervix long axis and anterior cervical axis angle of PID patients and healthy controls were evaluated. Gravida, parity, history of smoking were significantly higher in the PID group (n = 75) than the control group (n = 74).The uterine body longitudinal axis (p = 0.001) and transverse axis (p = 0.005) were significantly lower, and the cervix longitudinal axis (p < 0.001) and the anterior uterocervical angle (p < 0.001) were significantly higher in the PID group than the control group. Binary logistic regression analysis showed that uterine body (UTX) longitudinal axis (p = 0.005), uterine cervix longitudinal axis (p < 0.001) and UCA (p < 0.001) were significant predictors of PID. Uterine body longitudinal axis, uterine cervix longitudinal axis, and UCA can be associated to PID.
