    ObjectiveTo systematically review the value of contrast-enhanced ultrasound in diagnosis of benign and malignant renal tumors.

Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using Meta-Disc 1.4 software. ResultsSeven studies involving 462 patients were finally included. ROC curve showed shoulder-arm shape. The results of Spearman suggested significance of the threshold effect. The results of meta-analysis showed that, the area under curve (AUC) was 0.98.
