INTRODUCTIONSome women conclude that any deviation from their personal menstrual experience is abnormal, and they will take treatment for the same. Many of them ignore even significant variations in their menstrual function; sometime to such an extent that severe iron deficiency anemia occurs. The most common reason for gynecological referrals is abnormal uterine bleeding in premenopausal and postmenopausal women. More than 40% of them are having polyps and fibroids. Hysteroscopy gives an accurate diagnosis by direct visualization of the cervical canal and endometrial cavity, and results in medical or surgical management related to the specific etio-pathology, avoiding the need for major surgery 1 . Previously dilatation and curettage was usual method of evaluating abnormal uterine bleeding and it misses the cause in more than 50% of the cases. 1,2Gimpelson and Rappold 2 reported that hysteroscopy is considered an accurate "gold standard" in endometrial cavity evaluation and hysteroscopy associated with guided biopsy was more accurate than dilatation and curettage.The aims and objectives of this study were to assess the accuracy of diagnostic hysteroscopy in evaluation of abnormal uterine bleeding and to correlate its findings with histopathology reports. METHODS ABSTRACT Background:The objective was to assess the accuracy of diagnostic hysteroscopy in evaluation of abnormal uterine bleeding and to correlate hysteroscopic findings with histopathology reports. Methods: A prospective study was carried out at our institute from January 2010 to December 2013. Ninety cases were included in this study. Patients" age varied from 20 to 60. Those women with the history of abnormal uterine bleeding were admitted. In all cases diagnostic hysteroscopic examination and dilatation and curettage were carried out. Endometrium was sent for histopathology and correlation of hysteroscopic findings with histopathology reports was studied. Results: Various findings on hysteroscopy are as following: proliferative endometrium 36.66%, secretary endometrium 17.77% endometrial hyperplasia 24.44%, atrophic endometrium 5.55%, endometrial polyp 8.88%, submucous fibroid 4.44%, and endometrial carcinoma 2.22%. Conclusions: Hysteroscopy is an eye in uterus and it provides more accurate diagnosis than dilatation and curettage alone in patients with abnormal uterine bleeding.
