The goal of this study is to evaluate the correlation between abnormal uterine bleeding in IUD users and the position of IUD, uterine size, endometrial thickness, uterine artery Doppler [pulsitility index (PI); Resistivity index (RI)] using transvaginal ultrasound and Doppler.

100 women divided into two groups (50) women who have been using an IUD for at least 6 months, and experienced symptoms after placement of IUD in the form of menorrhagia may be in the form of increase in the amount and/or duration of the menstruation and (50): women who have been using an IUD for at least 6 months, and did not experience menorrhagia after insertion of IUD.

There is a possible relationship between the IUD location inside the uterine cavity and the abnormal uterine bleeding among IUD users.  The higher the position of the IUD, the less the frequency of abnormal uterine bleeding associating the IUD, the IUD-F, IUD-M, IUD-E and IUD-IO distances may be utilized as good predictors for the IUD location inside the uterus. The PI and RI were significantly lower in women with IUD-induced menorrhagia than in those using IUD without complaining of menorrhagia.
