Diagnostic Value of Ultrasonography Combined with Hysteroscopy in Intrauterine Space-Occupying Abnormalities

The aim of this study was to analyze the diagnostic significance of ultrasonography combined with hysteroscopy for intrauterine space-occupying abnormalities. A total of 99 patients with uterine space-occupying abnormalities treated in hospitals were enrolled. The patients were divided into three groups according to different disease types: the submucosal myoma group, endometrial polyp group, and placenta residue group, with 33 patients in each group. The differences and diagnostic effects in intrauterine ultrasound, hysteroscopic findings, and surgical histopathology were observed in each group. Outcome measures: it was to compare the sensitivity, specificity, and accuracy of intrauterine ultrasound and angiography for intrauterine space-occupying lesions using surgical and pathological examination methods as the gold standard; the relationship between the location, number, size, appearance, and serosal layer of intrauterine lesions was clearly shown; the location, number, appearance, and echogenicity of space-occupying abnormalities under hysteroscopy were observed. The results showed that the diagnostic rates of endometrial polyps, submucous myoma, and residual placenta were 90.9%, 80.8%, and 72.7%, respectively. However, the sensitivity, specificity, and accuracy of ultrasonography in the diagnosis of endometrial polyps were 90.0%, 66.7%, and 87.9%, respectively; those of hysteroscopy in the diagnosis of endometrial polyps were 96.7%, 66.7%, and 93.9%, respectively; and combined diagnosis was 96.7%, 100.0%, 97.0%, 100.0%, and 75.0%. The sensitivity, specificity, and accuracy of ultrasonography in the diagnosis of submucous myoma of the uterus were 88.9%, 50.0%, and 81.8%, respectively; those of hysteroscopy in the diagnosis of submucous myoma of the uterus were 96.3%, 83.3%, and 93.9%, respectively; and combined diagnosis was 100.0%, 83.3%, 97.0%, 96.4%, and 100.0%. The sensitivity, specificity, and accuracy of ultrasonography in the diagnosis of uteroplacental remnants were 87.5%, 66.7%, and 81.8%, respectively; those of hysteroscopy in the diagnosis of uteroplacental remnants were 91.7%, 77.8%, and 87.9%, respectively; and combined diagnosis was 95.8%, 88.9%, 93.9%, 95.8%, and 88.9%. In summary, ultrasonography combined with hysteroscopy can improve the diagnostic sensitivity and accuracy for intrauterine space-occupying abnormalities.
