    Abstract:
    STUDY OBJECTIVE: To compare the effectiveness of transvaginal ultrasound versus hysteroscopy in the diagnosis of benign intrauterine lesions, with histology as the gold standard. DESIGN: Retrospective study (Canadian Task Force classification II-1). SETTING: Unit of Reproductive Medicine, Department of Obstetrics and Gynecology of Clinica Las Condes, Santiago, Chile. PATIENTS: Infertile women who had undergone complete fertility evaluation. INTERVENTION: Transvaginal ultrasound, hysteroscopy, and histologic evaluation of endometrial samples performed in all 126 women. MEASUREMENTS AND MAIN RESULTS: The most frequent condition was a normal cavity (59.5%), followed by endometrial polyps (34.9%) and fibromyomas (3.9%). Synechiae and bone metaplasia were extremely rare. Sensitivity of transvaginal ultrasound for the diagnosis of endometrial polyps was 95.6% compared with 89.9% for hysteroscopy (NS). Specificity was 97.4% with transvaginal ultrasound versus 93. 3% with hysteroscopy (NS). Positive and negative predictive values were similar for both methods. CONCLUSION: Transvaginal ultrasound is as effective as hysteroscopy in diagnosing benign intrauterine lesions. It could be the first clinical diagnostic test in the investigation of the uterine cavity.
