[Diagnosis of uterine diseases by combined hysteroscopy and ultrasonography].

OBJECTIVE: To investigate the diagnostic value of combined hysteroscopy with ultrasonography. METHODS: 477 patients were diagnosed by hysteroscopy, ultrasonography, or hysteroscopy combined with ultrasound. The results of the 3 groups were compared with the findings after operations. RESULTS: This study indicated to diagnose intrauterine lesions, intramural diseases or pelvic disorders, hysteroscopy with ultrasonography was significantly better than either methods alone. The accuracy rate, false positive rate as well as false negative rate were 98.32%, 1.26% and 0.04% respectively. CONCLUSION: Hysteroscopy is used for diagnosis and treatment of intrauterine lesions, and ultrasonography is difficult to show actual location of lesions within uterine cavity. The present study has shown that hysteroscopy combined with ultrasound could increase the effectiveness and accuracy of uterine diseases' diagnosis.
