Objectives: To assess the reproducibility of hysteroscopic diagnosis in the various types of endometrial hyperplasias and to compare different classifications of endometrial hyperplasia from this point of view.
Study Design: 109 endometrial hyperplasias, diagnosed in the last 5 years with hysteroscopy, were all biopsied and had a pathological examination. We tried to estimate the accuracy of hysteroscopy comparing the various classifications of endometrial hyperplasia to the final pathologic diagnosis.
