title: Comparison of Ultrasonography and Hysteroscopy in the Diagnosis of Intrauterine Lesions in Infertile Women
abstract: Transvaginal ultrasound is a noninvasive diagnostic technique that remains to be proved as accurate as hysteroscopy in the diagnosis of benign intrauterine lesions. We compared its efficacy with that of hysteroscopy in the diagnosis of benign intrauterine pathology in 126 infertile women in whom the diagnosis was confirmed by histologic studies. The women had a complete evaluation with preoperative transvaginal ultrasound, hysteroscopy, and histologic analysis of uterine cavity specimens. Sensivity, specificity, and predictive values were calculated for ultrasound and hysteroscopy considering the histologic study as 100%. Sensivity was 95% and 100%, and specificity 97.4% and 93.7% for transvaginal ultrasound and hysteroscopy, respectively. The positive predictive value for benign intrauterine lesions was 100% for ultrasound and 89.8% for hysteroscopy. The most frequent intrauterine lesions found were polyps and myomas. Transvaginal ultrasound is a valuable method of diagnosing benign intrauterine lesions in infertile women, and is especially important as a noninvasive technique to plan hysteroscopic surgery.
