Results

The mean renal elasticity of mild, moderate, and severe renal fibrosis was 3.40, 3.98, and 4.77, respectively. Renal elasticity of native kidneys was significantly positively correlated with the grade of renal fibrosis (Pā€‰=ā€‰0.003). At the cutoff point of 3.81, the area under the curve, sensitivity, and specificity were 0.778, 68.4%, and 81.8%, respectively.

Other related information

The patients who participate in this study will be received blood biochemical examination, urinalysis, conventional echography and renal histological evaluation before the examination of ultrasound elastography. We analyze those data, and evaluate the accuracy of the diagnosis for renal elasticity by ultrasound elastography to other procedures.
