Abstract: Objective To measure the renal tissue texture or flexibility with virtual touch quantization (VTQ) and to tentatively examine its clinical application in patients with chronic kidney disease(CKD).Methods A total of 750 patients (1500 kidneys) were performed with VTQ,including 400 cases in the control group,and 350 cases in the CKD group.A conventional ultrasound examination (two-dimensional,color Doppler) were first taken,and then the shear wave velocity (Vs) was measured which reflected the textural elastic.Results In both groups the Vs was the highest in renal cortex with significant difference (P<0.05); renal cortical region Vs in CKD group was lower than those in control group (P<0.05),while Vs of renal medulla and renal sinus had no significant difference in the two groups.The severity of renal dysfunction was increased along with a Vs decrease of renal cortex.Conclusion VTQ is helpful to assess renal function of patients with CKD.
