Comparison of transvaginal sonography and saline contrast sonohysterography in women with abnormal uterine bleeding: correlation with hysteroscopy and histopathology.

Background: Transvaginal ultrasound is used conventionally as initial investigation of patients with abnormal uterine bleeding but saline contrast sonohysterography is a better technique to reliably distinguish focal from diffuse endometrial lesions. This study was performed to compare the ability of transvaginal ultrasonography and saline infusion sonohysterography as initial modality for the diagnosis of endometrial abnormalities in women with abnormal uterine bleeding.

Patients And Methods: In a prospective study, 100 women with abnormal uterine bleeding were submitted to sequential examination by transvaginal ultrasound, and sonohysterography.
