The diagnostic accuracy of transvaginal ultrasonography and vaginal sonohysterography in detecting endometrial polyps in women suffering abnormal uterine bleeding are compared.
One hundred and six patients suffering from menometrorrhagia were studied. To detect whether there was endometrial polyp or not, these patients were subjected to transvaginal ultrasonographic examination as well as to sonohysterography. The final diagnosis was established by diagnostic hysteroscopy and its guided biopsy.
Transvaginal ultrasonography resulted in false positive and false negative rates of 25% and 36.2% respectively while the figures with sonohysterography were 5.4% and 8% respectively. Combining both techniques further improved such rates to 2.9% and 2.8% respectively but not significantly (p>0.1). The sensitivity and specificity were 64.5%, 75.5% for transvaginal ultrasonography, and 93.1%, 93.9% for sonohysterography (significantly higher: p<0.001).
Sonohysterography is significantly more accurate than transvaginal ultrasonography in the detection of endometrial polyps in cases with abnormal uterine bleeding. Combining both techniques did not significantly improve the diagnostic accuracy. Sonohysterography is an accurate and cost effective method which requires a little skill.
比较经阴道超声检查和阴道超声子宫造影术在检测异常子宫出血女性子宫内膜息肉方面的诊断准确性。
对106例月经过多患者进行研究。为检测是否存在子宫内膜息肉，这些患者接受了经阴道超声检查以及超声子宫造影术。最终诊断通过诊断性宫腔镜检查及其引导下活检确定。
经阴道超声检查的假阳性率和假阴性率分别为25%和36.2%，而超声子宫造影术的相应数字分别为5.4%和8%。两种技术联合使用可进一步将这些比率分别提高至2.9%和2.8%，但差异不显著（p>0.1）。经阴道超声检查的敏感性和特异性分别为64.5%、75.5%，超声子宫造影术的敏感性和特异性分别为93.1%、93.9%（显著更高：p<0.001）。
在检测异常子宫出血病例中的子宫内膜息肉方面，超声子宫造影术比经阴道超声检查显著更准确。联合使用两种技术并未显著提高诊断准确性。超声子宫造影术是一种准确且经济有效的方法，所需技术要求不高。
