本文用超声对７１例肾移植术后患者进行床旁动态监测，连续观察了功能正常移植肾及急性排异（ＡＲ）、急性肾小管坏死（ＡＴＮ）的形态学和血流动力学变化。结果：１．功能正常组移植肾术后１１天，移植肾厚径、截面积、锥体高、宽同基础值相比分别增长９．７％、１８．８％、２５．２％；２．ＡＲ组移植肾排异后１５天，移植肾厚径、截面积、锥体高、宽分别增长２１．８％、３３．３％、３８．２％、４５．７％，高于正常组（Ｐ＜０．０１）。肾窦面积减少１９．１％。低于正常组，（Ｐ＜０．０１）；３．ＡＴＮ组移植肾锥体肿大峰值时间早于ＡＲ，肿大程度略重于ＡＲ；４．正常组移植肾术后７天，弓形动脉ＲＩ值与基础测值相比有明显升高（ｐ＜０．０１）并达峰值０．５６；５．ＡＲ、ＡＴＮ血流动力学变化早于临床及形态学改变
In this paper, 71 patients with renal transplantation after bedside dynamic monitoring, continuous observation of the function of normal kidney and acute rejection (AR), acute tubular necrosis (ATN) morphology and hemodynamic changes. Results: 1. In the normal group, the thickness, cross-sectional area, height and width of the allograft kidney increased by 9.7%, 18.8% and 25.2% respectively compared with the baseline value 11 days after transplantation. In the AR group, the diameter, cross-sectional area and the height and width of the transplanted kidney increased by 21.8%, 33.3%, 38.2% and 45.7% respectively 15 days after transplantation rejection <0.01). Sinus area decreased by 19.1%. Lower than normal group (P <0.01); 3. In ATN group, the peak time of edema was earlier than that of AR, and the degree of enlargement was slightly more than that of AR.4. In the normal group 7 days after transplantation, the RI value of the arcuate artery was significantly higher than the baseline value (p <0.01) and reached a peak value of 0.56. AR, ATN hemodynamic changes earlier than clinical and morphological changes
