目的探讨彩色多普勒超声在诊断急慢性肾脏弥漫性病变中的临床价值及预后意义。方法随机抽取2013年11月至2016年10月郑州大学附属洛阳市中心医院86例肾脏弥漫性病变患者作为观察组,根据疾病类型进一步分为观察A组(慢性肾病43例)与观察B组(急性肾病43例),另选取同期体检健康者43例作为对照组。入院后均行彩色多普勒超声检查,对比三组肾皮质厚度、肾脏大小及相关超声参数[叶间动脉阻力指数(RI)、叶间动脉收缩期峰值流速(V_(max))、段动脉加速时间(AT)]。结果观察A组肾皮质厚度、肾脏长、宽、厚水平均低于对照组,观察B组肾皮质厚度、肾脏长、宽、厚水平均高于对照组,差异有统计学意义(P<0.05);观察A组RI、AT高于对照组,V_(max)低于对照组,观察B组RI、AT低于对照组,V_(max)高于对照组,差异有统计学意义(P<0.05)。结论彩色多普勒超声检查在急慢性肾脏弥漫性病变诊断中可通过肾实质厚度、肾脏大小及相关超声参数对疾病作出准确有效判断。
Objective To investigate the clinical value and prognostic significance of color Doppler ultrasound in the diagnosis of diffuse lesions of acute and chronic renal disease. Methods Eighty-six patients with diffuse kidney disease in Luoyang Central Hospital Affiliated to Zhengzhou University from November 2013 to October 2016 were randomly divided into observation group A (chronic kidney disease 43 cases) and observation group B 43 cases of acute kidney disease), and the other 43 cases of healthy subjects were selected as the control group. Color Doppler echocardiography was performed after admission. The renal cortical thickness, kidney size and related ultrasound parameters (RI, Vmax), segmental arteries Acceleration time (AT)]. Results The renal cortical thickness, the length, width and thickness of kidney in group A were lower than those in control group. The thickness of renal cortex, the length, width and thickness of kidney in group B were significantly higher than those in control group (P <0.05) ). The RI and AT in group A were higher than those in control group, and the V max were lower than those in control group. The RI and AT in group B were lower than those in control group, and the V max were higher than those in control group (P < 0.05). Conclusions Color Doppler ultrasonography in the diagnosis of acute and chronic renal diffuse lesions can be accurately and effectively judged by the renal parenchymal thickness, kidney size and related ultrasound parameters.
