Factors increasing the detection rate of intrauterine lesions on hysteroscopy in infertile women with sonographically normal uterine cavities

Background: Detection of intrauterine lesions is important for infertile women, as the uterine cavity is the site for embryo growth. This study aims to investigate factors that increase the detection rate of intrauterine lesions on office hysteroscopy in infertile women with sonographically normal uterine cavities. Methods: We retrospectively enrolled 1726 infertile women who had normal uterine cavities on two-dimensional transvaginal sonography. Office hysteroscopy was performed in the early proliferative phase of the menstrual cycle. Results: Intrauterine lesions were detected in 260 (15.1%) of the 1726 women. In women who suffered from abnormal uterine bleeding (AUB), hypomenorrhea or had a history of dilation and curettage (D&C), the detection rates of intrauterine lesions on office hysteroscopy were 41.4%, 22.2% and 19.4%, respectively. The predictive rate of abnormal hysteroscopic finding was 22.4% in women with at least one of these three clinical features, while it was 9.6% in those without. Conclusion: AUB, hypomenorrhea, and previous D&C are the three factors that increase the detection rate of intrauterine lesions on office hysteroscopy in infertile women with sonographically normal uterine cavities.
