OBJECTIVE: To evaluate the diagnostic accuracy of transvaginal ultrasonography, sonohysterography and hysteroscopy in patients presenting with abnormal uterine bleeding. DESIGN: Prospective, blind, comparative study. SETTING: Outpatient clinic and day surgery unit of a district hospital specializing in operative hysteroscopy. PATIENTS: One hundred consecutive patients referred with abnormal uterine bleeding (AUB). INTERVENTIONS: Transvaginal ultrasonography and sonohysterography were performed in the outpatient clinic. Within 1 week, all patients underwent operative hysteroscopy. MAIN OUTCOME MEASURES: All diagnoses established by transvaginal ultrasonography, and sonohysterography were compared to the appearance of the cavity using hysteroscopy as well as the histological diagnosis from removed tissues. RESULTS: In 88 patients information suitable for analysis was obtained by all methods. The detection rate of focal intrauterine pathology using sonohysterography was (94.1%), but was significantly lower with transvaginal ultrasonography (23.5%). In about 75% of all cases none of the methods used was able to correctly detect endometrial hyperplasia. CONCLUSIONS: 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.
