Abstract:
Objective To investigate the application value of virtual touch tissues quantization(VTQ)in the stages of type 2 diabetic nephropathy.Methods 120 cases of type 2 diabetes were divided into 3 groups according to urinary albumin excretion rate (UAER):diabetes without urinary albumin,diabetes with trace albuminuria and diabetes with mass albuminuria.The control group consisted 30 normal cases.VTQ was used to measure the renal shear wave velocity (SWV),then compare were made between the 4 groups.Besides,correlation analysis was made between SWV and UAER in diabetic nephropathy group.Results When compared SWV,there was no significant difference between diabetes without urinary albumin and control group (P =0.144),but there was significant difference between each 2 group of diabetes with trace albuminuria,diabetics with mass albuminuria group and control group (P ＜ 0.05).There was also significant difference between each 2 group of diabetes (P ＜ 0.05).The correlation coefficients for SWV and UAER in diabetes were 0.697(P ＜0.05).ROC analyses showed the area under curves for SWV diagnosis for diabetic nephropathy was 0.93.The best cutoff point,sensitivity and specificity were 2.43 m/s,85.7％ and 84.5 ％,respectively.Conclusions The renal SWV increases as the renal injury progresses,which also plays an important role in diabetic nephropathy stages.
