摘　　要：目的使用声触诊组织定量分析(VTQ)测量慢性肾病患者肾组织质地或弹性,探讨VTQ在肾病患者中的应用价值。方法正常对照组400例、慢性肾病组350例(共1500个肾)行VTQ,测量反映组织弹性顺应力的横向剪切波速度(Vs)。结果两组患者Vs均为肾皮质>肾髓质>肾窦(P<0.05);慢性肾病组肾皮质区域Vs较正常对照组偏低(P<0.05),肾髓质、窦部Vs则无明显差别。随着肾功能损害程度的加重,肾皮质区Vs减低。结论 VTQ有助于评估慢性肾病患者的肾功能。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 （P0.05）; renal cortical region Vs in CKD group was lower than those in control group （P0.05）,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.
