Background and objectives: Hysteroscopy is now accepted as the gold standard in evaluation of uterine cavity in patients with AUB. This study was planned to evaluate the role of hysteroscopy in diagnosis of patients with AUB. Methodology: This is a cross-sectional study done in the Department of Obstetrics and Gynaecology, Karnataka Institute of Medical Sciences, Hubli. A total of 50 women who presented with complaints of abnormal uterine bleeding from December 2012 to November 2013 were studied. These women were subjected to hysteroscopy and histopathological examination. Results: The mean age was 39.86 ± 8.29 years. 60% of women complained of menorrhagia and postmenopausal bleeding was noted in 8% of the women. Endometrium hyperplasia was the commonest abnormality (16%) on hysteroscopy followed by endometrium polyp (12%). Histopathological examination showed endometrium hyperplasia in 16% and endometrium atrophy in 8%. The sensitivity and diagnostic accuracy of hysteroscopy in predicting accurate diagnosis was 88.24% and 84% respectively with 'good' agreement between hysteroscopy and histopathology (Kappa value -0.701). Conclusion:Hysteroscopy is highly sensitive diagnostic procedure and provides useful information about the uterine cavity. Hence it may be ideal method for the evaluation of patients with abnormal uterine bleeding.
