Transvaginal ultrasonography sonohysterography and <i>operative hysteroscopy</i> for the evaluation of abnormal uterine bleeding

Sonohysterography was significantly better than transvaginal ultrasonography in detecting focal intrauterine pathology. Visual examination at operative hysteroscopy yielded no additional information to the detection or exclusion of focal lesions than was obtained at outpatient sonohysterography. All methods performed equally in assessing endometrial pathology. We conclude that sonohysterography may replace diagnostic hysteroscopy in many patients with AUB.
