Correlation of endometrial thickness, cycle day and histopathology in women with abnormal uterine bleeding.

Objective: To correlate the endometrial thickness measured by transvaginal sonography (TVS), cycle day and menstrual status with histopathology in women with abnormal uterine bleeding and to evaluate the accuracy of transvaginal sonography in detecting intrauterine abnormalities as compared to hysteroscopy.

Methods: This prospective study was conducted in the Department of Obstetrics and Gynecology, Sultan Qaboos University Hospital between January 1998 and July 2002. Transvaginal sonography was performed in 160 women with abnormal uterine bleeding, followed within 48 hours by hysteroscopy and endometrial biopsy.
