Assessment of the role of Transvaginal color Doppler ultrasound in prediction of menorrhagia among copper intra uterine device users

Objective: to evaluate the effect of copper T IUCD on the uterine artery blood flow causing menorrhagia and to assess the role of Transvaginal color Doppler ultrasonography in prediction of this menorrhagia.Method: it was a prospective cross sectional study which was conducted on 84 patients referred to the obstetrics and gynecology family planning clinic of the Zagazig University Hospital and Zagazig General Hospital for insertion of an IUD (Cu T-380A) from 1/1/2019 to 30/7/2019. The Transvaginal ultrasound and Doppler had been done at time of insertion on the 4th or 5thday of menstruation. The patients had been classified into two groups the according to presence or absence of menorrhagia; group 1 (n =37): with menorrhagia, group 2 (n = 47) without menorrhagia. Results: PI and RI at time of insertion were significantly lower in women with IUD -induced menorrhagia than in those using IUD with normal menstrual bleeding (p-value <0.001). Uterine artery PI ≤1.99 (sensitivity 97.3% and specificity 100%, with area under the curve, AUROC of 0. 981and p-value <0.001) and RI ≤0.82 (sensitivity 94.6%and specificity 100%, with area under the curve, AUROC of 0.957and p-value <0.001) have been associated with menorrhagia after IUD insertion. Conclusions: any women tend to have a cu T 380A IUCD for contraception with a PI lower than 1.99 and RI lower than 0.82 will have menorrhagia after insertion, so they should use another way for contraception
