摘　　要：本文对43例肾移植患者进行超声观察，结果表明：①正常对照组、急性排异组（AR组）、急性肾小管坏死织（ATN组）的移植肾长径分别为10．83±0．86cm，12．75±067cm，11．15±0．54cm。AR组长径大于正常对照组（P＜0．05），ATN组长径与对照组无统计学差异。②正常对照组、AR组、ATN组的皮质部RI值分别为：O．66±0．04，0．87±0．07，0．81±0．06。AR组和ATN组RI均明显高于对照组，但AR组和ATN组间无统计学差异（P＞0．05）。③AR组可观察到肾皮质回声增强，肾窦回声减低、面积缩小，集合系统粘膜增厚等表现。④经抗排异治疗后，AR组RI值约5～7大恢复正常，而ATN组则需10～14天。The renal sonograms lengths of 43 cases who received renal transplant were studied. It showed that the lengths of the normal renal transplant control group. the AR group and the ATN group were 10. 88±0. 86cm, 12. 75±0. 67cm, 11. 15± 0. 54cm, respectively ; RI of cortex artery was 0. 66±0. 04 in control group, 0. 87± 0. 07 in AR group,and 0. 81±0. 06 in ATN group. Both the AR and ATN group showed obviously higher RI than the control group. Some echographic signs were perceived in AR patients, including hyperechogenicity of the renal cortex, decreased renal sinus area with hypoechogenicity, and thickening of the collecting system. During AR Period, RI problems usually resolved in about 5-7days＇antirejection therapy, while ATN needed 10-14 days.
