糖尿病肾病(diabetic nephropathy,DN)是糖尿病(diabetes mellitus,DM)严重的微血管并发症之一,是导致DM患者死亡的主要原因,早期发现并采取适当措施干预至关重要。临床诊断DN主要依据血和尿的实验室检查。二维超声通过对肾脏实质回声和体积的观察,为动态监测DN的发生、发展提供了一种可行的方法。彩色多普勒技术能够显示肾内血流并提供血流参数指标,极大地丰富了诊断信息。目前,随着超声仪器性能的提高以及三维超声、超声造影等新技术的出现,使彩色多普勒超声对
Diabetic nephropathy (DN) is one of the serious microvascular complications of diabetes mellitus (DM), which is the main cause of death in DM patients. It is very important to detect early and take proper intervention. Clinical diagnosis of DN mainly based on laboratory tests of blood and urine. By observing the real echo and volume of kidney, two-dimensional ultrasound provides a feasible method for dynamically monitoring the occurrence and development of DN. Color Doppler technology can display renal blood flow and provide blood flow parameters, which greatly enriched the diagnostic information. At present, with the improvement of ultrasound instrument performance and the emergence of new technologies such as three-dimensional ultrasound and contrast-enhanced ultrasound, color Doppler ultrasound
