摘要

目的：

评估超声造影与增强CT对肾癌囊性变的诊断价值。

方法：

分析2005年7月2017年4月行常规超声、超声造影和增强CT检查的102例经病理证实为囊性肾癌的患者的影像学资料，应用 Fisher精确概率法进行分析。

结果：

102例肾癌囊性变均经外科手术后病理学检查证实，包括92例透明细胞癌、6例嫌色细胞癌和4例乳头状肾细胞癌。102例肾占位性病变彩超检查的血流显示率为82.35%（84/102），超声造影血供显示率为98.04%（100/102），增强CT血供显示率为95.10%（97/102）。超声造影误诊4例为复杂囊肿，诊断准确率为96.08%（98/102）。增强CT误诊8例为复杂囊肿，3例为血管平滑肌脂肪瘤，2例未发现病灶，诊断准确率为87.25%（89/102）。超声造影Bosniak分级：Ⅱ级2例，ⅡF级2例，Ⅲ级18例，Ⅳ级80例；增强CT Bosniak分级：Ⅱ级3例，ⅡF级5例，Ⅲ级17例，Ⅳ级75例。Fisher显著性检验结果显示，超声造影与增强CT检测结果差异无统计学意义(

=0.710)。

结论：

超声造影与增强CT均可使用Bosniak分级诊断肾癌囊性变，超声造影诊断效果不亚于增强CT，可为临床决策提供帮助。

Abstract

Objective:

To assess the value of contrast-enhanced ultrasonography (CEUS) in evaluating cystic renal carcinoma compared with contrast-enhanced computed tomography (CECT).

Methods:

The imaging data of 102 cystic renal carcinoma patients from July 2005 to April 2017 who received ultrasound

CEUS and CECT diagnosis were analyzed. Fisher's exact test was used to analyze the differences in the diagnosis data.

Results:

All patients were proved by operation and pathology

including 92 cases of c

lear cell renal carcinoma

6 cases of chromophobe renal cell carcinoma

4 cases of papillary renal cell carcinoma. The diagnostic accuracy of CEUS for cystic renal carcinoma was 96.08% (98/102) and 87.25% (89/102) of CECT. Bosniak classification of CEUS: grade Ⅱ in 2 cases

grade ⅡF in 2 cases

grade Ⅲ in 18 cases

grade Ⅳ in 80 cases. Bosniak classification of CECT: grade Ⅱ in 3 cases

grade ⅡF in 5 cases

grade Ⅲ in 17 cases

grade Ⅳ in 75 cases. There was no significant difference (

=0.710)．

Conclusion:

CEUS may play a similar role to CECT in the diagnosis of cystic renal carcinoma based on Bosniak classification. CEUS is helpful in the diagnosis of cystic renal carcinoma．
