目的：分析彩色多普勒超声在肾髓质钙沉着症中的应用价值。方法回顾性分析2011—2015年期间在该院行彩色多普勒超声诊断肾髓质钙沉着症的68例患者的临床资料，观察患者的超声诊断特点以及血流动力学改变。结果68例行彩色多普勒超声诊断肾髓质钙沉着症的患者中，诊断阳性共65例，阴性3例，诊断的准确率为95.6%，65例肾髓质钙沉着症患者中包括皮质型30例，髓质型32例，混合型3例，患者的两侧肾脏大小正常，形态对称，包膜光滑，皮质和髓质界限较为清楚，肾脏的皮质厚度和回声均正常，在患者的髓质内，有密集点状的强回声，形态和椎体的形态基本一致，有一侧有弱声影。结论彩色多普勒超声在肾髓质钙沉着症中应用，准确率较高，可以有效的显示内部的形态、血流变化等指标，具有重要的临床诊断价值。%Objective To analyze the value of color Doppler ultrasound in the renal medulla of calcium applications. Methods Convenient selection a retrospective analysis of clinical data by color Doppler ultrasound diagnosis of renal medullary calcinosis disease 68 patients were retrospectively analyzed the period from 2011 to 2015, observed in patients with ultrasonic diagnostic characteristics and hemodynamic change. Results 68 patients with routine color Doppler ultra-sound diagnosis of renal medullary calcinosis disease, the diagnosis of a total of65 positive cases, negative in 3 cases, the diagnostic accuracy was 95.6%, 65 cases of renal medullary calcinosis patients included cortical 30 cases, 32 cases of medullary, mixed three cases, both sides of the patient's normal kidney size, shape symmetry, smooth coated, cortex and medulla boundaries more clearly, renal cortical thickness and echo were normal in patients within the medulla, a strong e-cho dense point-like, form and shape of the vertebral body are basically the same, there is one side of the weak acoustic shadow. Conclusion Color Doppler ultrasound in the renal medulla calcium PAP applications, high accuracy, can effectively display the form inside the blood flow changes in other indicators, has important clinical diagnostic value.
