Abstract
In a retrospective study of 2404 cases of IUD[intrauterine device]-induced bleeding problems, the type and timing of bleeding as well as the types of conservative therapy were evaluated. The non-hormonal treatment (uterotonics, Ca, vitamins C, and K etc.) proved to be significantly less effective (P < 0.05) than the hormonal therapy (estrogen, gestagen and combined preparations). The rate of effectiveness was 80.1% and 86.7%, respectively. Because the effectiveness of the conservative therapy is 80%, even in the non-hormonal group, the IUD should be removed only if this treatment proves to be ineffective. The importance of routine colposcopic and cytological screening is emphasized.
