Measurement of the Anterior Uterocervical Angle for Predicting the Displacement of Copper Intrauterine Devices (T-Cu380A): A Prospective Cohort Study

Background: To determine the value of uterocervical angle for predicting displacement copper intrauterine devices (IUDs). Methods: We conducted a prospective cohort study between December 2020–June 2021 at family planning outpatient clinics Kanuni Sultan Suleyman Training and Research Hospital, Istanbul Health Sciences University. A total 143 patients who had IUDs (T-Cu380A) inserted contraception were evaluated from 6th week to 5 years after insertion. Patients divided into two groups according ultrasonographic examinations that revealed whether their IUD “displaced” or in “normal” position. The (UCA) was measured by transvaginal ultrasonography investigated as it predictive IUDs. Results: Of women participating study, 67 (46.9%) displaced position, 76 (53.1%) normal No statistically significant difference found patient age, body mass index, educational status, gravida, parity, mode delivery (p > 0.05). mean anterior UCA with 139.7 ± 8.2 degrees, while positions 125.3 12.9 degrees. Multiple logistic regression analysis increased 1.31-fold each one degree increase (95% confidence interval (CI): 1.06–1.63, p = 0.012). Conclusions: has Measurement is feasible method can thus be used screening tool allow additional counseling patients. cut-off 139.5 Women >139.5 degrees may benefit closer follow-up device placement.
