摘　　要：目的探讨彩色多普勒超声对移植肾急性肾小管坏死(ATN)肾动脉血流动力学变化规律及临床意义。方法应用彩色多普勒血流显像(CDFI)及彩色多普勒能量显像(CDEI)对69例肾移植手术患者进行监测,观察移植肾形态、大小、内部回声及血流分布情况,比较移植肾功能正常组、ATN组形态学及血流参数。结果与移植肾正常组比较,移植肾ATN组皮质变薄,锥体增高(P<0.01);移植肾ATN组皮质部血流减少(P<0.05),各级肾动脉阻力指数明显增高(P<0.05)。结论彩色多普勒超声在肾移植手术后ATN的诊治中具有重要的临床参考价值。Objective To study renal arteries hemodynamics and its clinical significance in the patients with renal transplantation acute tubular necrosis. Methods CDFI and CDEI were performed in 69 cases of renal transplantation. The parameters of morphology and hemodynamics were compared between acute tubular necrosis group （ ATN group） and normal group. Results The blood of renal cortex display decreased and the renal arterial resistant index increased in ATN. Conclusion It is valuable to both early diagnosis and treatment of acute tubular necrosis to monitor the blood flow parameters of renal arteries at all levels by color Doppler ultrasonography.
