摘    要:
目的:探讨彩色多普勒超声检查诊断早期糖尿病肾病( DN)的临床价值。方法选取Ⅰ、Ⅱ期DN患者69例( A组)与Ⅲ期DN患者75例( B组),行彩色多普勒超声肾动脉血流显像检查,统计分析两组肾主动脉(MRA)、叶间动脉(IRA)、肾段动脉(SRA)的血流收缩期峰值速度(Vsmax)、阻力指数(RI)以及舒张期最低速度(Vdmin)等血流参数的差异。结果 A组MRA、IRA、SRA的Vsmax分别为(73.±14.5)cm/s、(34.6±6.1)cm/s、(55.5±7.3)cm/s,B组分别为(71.±14.9)cm/s、(30.8±6.7)cm/s、(53.1±8.1)cm/s,两组IRA的Vsmax差异有统计学意义(t=3.562,P<0.01);A组MRA、IRA、SRA的Vdmin分别为(23.3±5.5)cm/s、(12.5±4.2)cm/s、(18.1±3.9)cm/s,与B组的(20.5±6.3)cm/s、(9.1±3.5)cm/s、(14.7±4.4) cm/s差异均有统计学意义(t=2.846、5.252、4.915,均P<0.01);A组MRA、IRA、SRA的RI分别为(0.6±0.1)、(0.6±0.1)、(0.6±0.1),与B组的(0.7±0.1)、(0.7±0.1)、(0.7±0.1)差异均有统计学意义(t=8.717、8.717、8.717,均P<0.01);A组肾脏体积平均为(121.8±27.9)cm3,与B组的(105.8±28.9)cm3差异有统计学意义(t=3.379,P<0.01)。结论彩色多普勒超声能清晰地显示患者肾脏大小,检测出肾动脉血流参数,对早期DN的诊断具有一定价值。

Abstract:
Objective To investigate the clinical value of color Doppler in the early diagnosis of diabetic nephropathy (DN).Methods 69 cases of DN Phase I,II patients (group A) and 75 cases Phase III (B group) all underwent renal artery line Doppler flow imaging inspection .Renal aorta ( MRA) ,interlobar artery ( IRA) ,renal seg-mental artery blood flow (SRA) peak systolic velocity (Vsmax),resistance index (RI) and diastolic minimum speed ( Vdmin) and other hemodynamic parameters of two groups were analyzed .Results The Doppler spectrum renal blood flow characteristics of early renal damage were:between group A,B,the main renal artery (MRA),the kidney arterial segment Vdmin significantly reduce ,RI was significantly higher;the interlobar artery Vsmax (t=3.562 5,P=0.000 5),Vdmin (t=5.252,P=0.000 0) were significantly lower,RI was significantly higher (t=9.166 0,P=0.000 0);with the severity of renal dysfunction ,kidney color flow imaging reduce ,the kidney volume was significantly reduced in patients with stage Ⅲ.Conclusion Color Doppler ultrasound can clearly show the size of the patient′s kidney and renal artery blood flow parameters ,which has certain value in the diagnosis of early DN .
