【目的】探讨多普勒超声在评价老年肾脏结构及血流动力学中的应用价值。【方法】随机选取老年慢性肾病患者85例(观察组),肾功能正常者85例(对照组),观察并比较两组双肾大小、形态、肾内结构、肾实质厚度及实质回声,并通过彩色血流图测量肾脏叶间动脉收缩期最高流速(PSV)、舒张期最低流速(EDV)、平均血流速度(Vm)、阻力指数(RI)、搏动指数(PI)等肾叶间动脉血流动力学参数。【结果】观察组肾脏长径和短径分别为(72.1±8.1)mm、(33.5±2.8)mm,均远短于对照组,肾实质较对照组明显增厚,实质回声显著增强,其差异均有统计学意义(P<0.05);观察组的 PSV、EDV、Vm 分别为(22.56±4.58)mL/s,(6.78±1.59)mL/s,(14.70±3.05)mL/s,均显著低于对照组(31.69±5.17,11.56±2.01,21.58±3.58),差异有显著性(P<0.05),而 RI及PI为0.69±0.28和1.07±0.65,均显著高于对照组(0.63±0.18和0.93±0.40),差异有显著性(P<0.05)。【结论】彩色多普勒超声在检测老年肾脏结构及血流动力学改变方面具有较高的临床价值。

To explore the value of Doppler ultrasound in the evaluation of kidney structure and hemodynamics in elderly people.[Methods]Totally 85 elderly patients with chronic kidney disease(observa-tion group)and 85 subjects with normal kidney function(control group)were randomly chosen.The size, shape and structure of two kidneys,renal parenchyma thickness and echo in two groups were observed and compared.Color flow mapping was used to measure renal interlobar artery peak systolic velocity(PSV),end diastolic velocity(EDV),mean blood flow velocity(Vm),resistance index(RI),pulsatility index(PI)and oth-er renal interlobar artery hemodynamic parameters.[Results]Renal long and short diameters in observation group were (72.1±8.1)mm and (33.5 ± 2.8)mm respectively,which were far shorter than those in control group.Compared with control group,renal parenchyma in observation group was thickened obviously and the echo was strengthened markedly,and there was significant difference(P<0.05).The PSV,EDV and Vm in observation group were (22.56±4.58 )mL/s,(6.78±1.59)mL/s and (14.70±3.05)mL/s respectively which were markedly lower than those in control group(P<0.05),while RI and PI in observation group were (0.69±0.28)and (1.07±0.65)respectively which were markedly higher than those in control group(P<0.05).[Conclusion]Color Doppler ultrasound in the measurement of renal structure and hemodynamics chan-ges in elderly people is of great clinical value.
