Abstract:
Objective To observe the optimal target areas for shear wave velocity(SWV)evaluation on stages of chronic kidney disease(CKD)in different sides(left,right),different parts(upper pole,middle part and lower pole)and different tissue(renal cortex,renal medulla,renal sinus)of kidney.Methods Sixty-five CKD patients(130 kidneys)were retrospectively collected.SWV were compared between different sides,among different parts and tissue of kidney.The optimal regions for evaluating CKD stages were screened.Results No significant difference of SWV was found between left and right kidneys in same parts for same tissue(all P＞0.05),while significant differences of SWV of the same tissue were noticed among upper pole,middle part and lower part of kidney on the same side(all P＜0.05),i.e at upper pole＞at middle part＞at lower pole.Significant differences of SWV were also observed among renal cortex,medulla and sinus of kidney in the same side and parts(all P＜0.05),and the sinus had the highest SWV.Intraclass correlation coefficient analysis showed that the repeatability of the measurements of SWV was the best at the middle part of kidney.Besides,significant differences of SWV were found between renal cortex and medulla at the middle part of kidney among patients with stages 1,2,3 and 4-5 CKD(all P＜0.05),while the highest SWV were observed in patients with 4-5 stage CKD(all P＜0.05).SWV of renal cortex and medulla at middle part were positively correlated with CKD stages(both P＜0.01),the area under the curve of them for evaluating stage of CKD was 0.802 and 0.774,respectively.Conclusion The optimal target areas for SWV evaluation on stages of CKD were renal cortex and medulla at middle part of kidney.
