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.

“…In a recent study, Dagdeviren et al reported that patients with broader pre-induction UCAs were prone to have a shorter duration of the active phase [ 7 ]. Although a recent study reported that UCA combined with CL predicted labor induction more satisfactorily than CL alone, UCA is more reproducible than CL [ 21 , 23 , 24 ]. However, as an ultrasound parameter established relatively recently, only a few studies have examined the use of UCA in full-term pregnancies to predict IOL.…”

The objective of this study was to determine the value of uterocervical angle (UCA) in predicting successful induction of labor (IOL) in singleton pregnant women compared to the Bishop score and cervical length (CL). A total of 205 normal term, singleton labor-induction cases were analyzed. Successful IOL was defined as the onset of active labor of induction. A comparative analysis was performed to evaluate the effectiveness of UCA, Bishop score, and CL in predicting IOL. Compared to the non-successful IOL group, the women in the successful IOL group had significantly wider UCA (p = 0.012) and higher Bishop score (p = 0.001); however, the CL was not significantly different (p = 0.130). UCA alone did not perform better than the Bishop score when predicting successful IOL. However, UCA combined with the Bishop score showed higher performance in predicting IOL (combined UCA > 108.4° and favorable Bishop score as sensitivity of 44.6%, specificity of 96.0%, PPV of 96.2%, and NPV of 43.6; combined UCA > 108.4° or favorable Bishop score as sensitivity of 85.7%, specificity of 50.0%, PPV of 78.7%, and NPV of 61.9). In conclusion, UCA combined with Bishop score may be an effective sonographic method for predicting successful IOL.
