肾动脉多普勒超声对经皮血管内支架成形术及支架置入术后肾动脉再狭窄的诊断价值：系统综述和Meta分析

目的采用Meta分析方法评估肾动脉多普勒超声（RDS）对经皮血管内支架成形术及支架置入术（PTAS）术后肾动脉再狭窄的诊断价值。 方法在数据库中检索自创刊至2018年12月的国内外文献，将检索得到的文献依照纳入与排除标准进行筛选，对最终纳入的文献进行质量评价和异质性检验，采用Meta分析方法评估RDS对PTAS术后肾动脉再狭窄的诊断价值。 结果最终纳入6篇合格文献，得到的合并敏感度和特异度分别为92%和89%，合并诊断比值比为83.33，总受试者工作特征曲线（SROC）曲线下面积为0.9542，Q指数为0.8963。 结论RDS在PTAS术后肾动脉再狭窄中具有较高的诊断准确性和诊断价值。

Diagnostic value of renal Doppler ultrasound for renal artery restenosis after percutaneous angioplasty and endoluminal stenting:a systematic review and Meta-analysis

Objective To evaluate the diagnostic value of renal duplex sonography(RDS)for renal artery restenosis after percutaneous angioplasty and endoluminal stenting(PTAS)by meta-analysis.Methods Domestic and international databases were searched from inception to December 2018 for relevant articles.The retrieved articles were screened according to the inclusion and exclusion criteria,and the quality evaluation and heterogeneity test were carried out.The diagnostic value of RDS for renal artery restenosis after PTAS was evaluated by meta-analysis.Results There were six qualified articles included in this metaanalysis.The pooled sensitivity and specificity were 92%and 89%,respectively,and the pooled diagnostic odds ratio was 83.33.The area under the curve(AUC)of the summary receiver operating characteristic(SROC)was 0.9542,and the Q*index was 0.8963.Conclusion RDS is highly valuable in the diagnosis of renal artery restenosis after PTAS.
