هیستروسونوگرافی ترانس واژینال و بیوپسی آسپیراسیون آندومتر، جانشینی برای کورتاژ تشخیصی

Background and purpose: This study is accomplished to compare the diagnostic accuracy of endometrial aspiration biopsy and transvaginal hysterosonography vs curettage of endometrium in primary diagnosis of abnormal uterine bleedings. Materials and methods : This prospective, controlled and clinical study was accomplished from January 20 th 1999 through 19 th 2000. Ât first 50 patients were selected for this study, but 3 for them were excluded later on, therefore the study was carried out with 47 patients. Routine transvaginal sonography was done to measure the size of uterus and ovaries, and endometrial thickness. Then transvaginal histerosonography was done to assess. endometrial thichness, symmetry and also presence of probable intracavitry masses. The next day, endometrial aspriration biopsy with pipelle curette was done. Final histologic sample was obtained from diagnostic curettage. The results of histopathologic assessment of diagnostic curettage were compared with hysterosonography and endometrial aspiration biopsy findings. Results: Çombination of transvaginal hysterosonography and endometrial aspiration could diagnose endometrial lesions with sensitivity of 87% and specificity of 88.6%. Ïn this study, none of the endometrial cavity disorders were undiagnostic. Çonclusion: Hysterosonography accompanied by endometrial biopsy is an acceptable clinical method in evaluation of abnormal uterine bleeding, and the patients can be treated confidently without any curettage which is having complication and additional expenses. The patients with uterine cavity masses or endometrial disorders can be referred for surgical procedures.
