The transplant blood flow was measured renal transplantation by ultrasonic duplex scanner composed of pulsed Doppler flowmeter and real-time B-mode linear scanner in 32 patients. The blood flow information could be obtained from anywhere of interest within the renal transplant. Then blood flow in 3 regions including renal hilum, central echoes and renal parenchyma were measured. The parenchymal peripheral blood flow was not always similar to the hilar central blood flow. Parenchymal blood flow was the most correlated with graft function and decreased remarkably during acute rejection episode. This method enabled detection of occurrence of acute rejection in the course of post-cadaver transplant ATN. Prolongation of delta t (acceleration time) in Doppler spectrogram from parenchyma was also reliable evidence for the deterioration of graft function. Ultrasonic duplex scanning is a useful method in managing post-transplantation patients because intrarenal hemodynamics can be evaluated by this method.
采用由脉冲多普勒流量计和实时B型线性扫描仪组成的超声双功扫描仪，对32例肾移植患者的移植肾血流进行了测量。可从移植肾内任何感兴趣的部位获取血流信息。然后测量肾门、中央回声和肾实质3个区域的血流。肾实质外周血流并不总是与肾门中央血流相似。肾实质血流与移植肾功能的相关性最强，在急性排斥反应期显著下降。该方法能够检测尸体肾移植后急性肾小管坏死过程中急性排斥反应的发生。肾实质多普勒频谱图中δt（加速时间）延长也是移植肾功能恶化的可靠证据。超声双功扫描是管理移植后患者的一种有用方法，因为通过该方法可以评估肾内血流动力学。
