摘要
目的应用Meta分析系统评价超声造影与增强CT诊断肾囊性占位性病变的价值。方法计算机检索PubMed、Cochrane图书馆、Embase、中国知网、万方等数据库,搜索超声造影与增强CT对肾囊性占位性病变的诊断性试验的相关文献,检索时间从建库至2016年12月31日。筛选出符合标准的文献,提取资料,评价文献质量,计算两种检查方法诊断肾囊性占位性病变的合并敏感性、特异性、阳性似然比、阴性似然比及诊断比值比,绘制汇总受试者工作特征(SROC)曲线,获取曲线下面积。结果共纳入8篇诊断性试验的文献(364个病灶);Meta分析结果显示,超声造影与增强CT诊断肾囊性占位性病变的合并敏感性、特异性、阳性似然比、阴性似然比及诊断比值比分别为0.96、0.77、3.69、0.07、54.88和0.84、0.81、4.12、0.22、20.74;SROC曲线下面积分别为0.9173和0.8634,差异无统计学意义。结论超声造影诊断肾囊性占位性病变的敏感性高于增强CT,具有较好的临床应用价值。
Objective To assess the diangostic value of contrast-enhanced ultrasonography and enhanced CT for renal cystic occupying lesions by Meta analysis. Methods Literatures about the diagnostic tests of renal cystic occupying lesions with contrast-enhanced ultrasonography and enhanced CT were retrieved in databases including PubMed,Cochrane Library,Embase,CNKI and Wanfang Data Service Platform,and were dated from the establishment of database to 31 December 2016. The literatures that comply with the standards were screened out,data was fetched and the quality of literature was assessed. The combined sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and diagnostic ratio of the two methods for the diagnosis of renal cystic occupying lesions were calculated,and the SROC curves was drawed,and the area under the SROC curve was obtained. Results Totally 8 diagnostic tests and 364 lesions were involved. The results of Meta analysis showed that the sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and diagnostic odds ratio for renal cystic occupying lesions diagnosis with contrast-enhanced ultrasonography and enhanced CT were 0.96,0.77,3.69,0.07,54.88 and 0.84,0.81,4.12,0.22,20.74,respectively. The areas under SROC curves were respectively 0.9173 and 0.8634,there was no significant difference. Conclusion Comparing with enhanced CT,contrast-enhanced ultrasonography has better diagnostic value for renal cystic occupying lesions.
