目的 本文旨在评价超声和CT对巨大肾血管平滑肌脂肪瘤的诊断价值及二者之间的相互关系。方法 选取我院2 0 0 0年以来泌尿外科就诊的肾源性巨大(6～2 2 cm)实性占位患者32例,将CT和超声的结果与病理诊断对照。结果 超声误诊率2 9.2 % ,CT误诊率2 5 % ,两种方法之间及单独应用超声检查与两种检查方法联合应用相比差异无显著性(P>0 .0 5 )。结论 超声和CT在肾血管平滑肌脂肪瘤诊断准确率方面无显著差异。超声可以作为肾血管平滑肌脂肪瘤术前的首选检查方法,CT是对超声的有益补充。
The purpose of this article is to evaluate the diagnostic value of ultrasound and CT for giant renal angiomyolipoma and the relationship between them. Methods Thirty-two cases of giant nephrogenic (6 ~ 2 2 cm) space-occupying patients in our hospital from 2000 to 2006 were selected. The results of CT and ultrasonography were compared with the pathological diagnosis. Results The misdiagnosis rate of ultrasound was 25.2% and the rate of misdiagnosis of CT was 25%. There was no significant difference between the two methods and the single application of ultrasound in the combination of the two methods (P> 0.05). Conclusion Ultrasound and CT in the diagnosis of renal angiomyolipoma have no significant difference in accuracy. Ultrasound can be used as the preferred method of preoperative examination of renal angiomyolipoma, CT is a useful supplement to ultrasound.
