Early acute rejection occurs between two and ten days after renal homotransplantation and has been recognized in eight of 156 renal transplants. Four of the eight patients developed spontaneous renal rupture unrelated to biopsies. Pathologically, there was acute passive congestion with areas of tubular necrosis, venous thrombi and perivenous lymphoplasia. Glomerular and arterial immunogenic injury was slight. Radiologically, the kidneys were enlarged with stretching of the interlobar and segmental arteries, decreased peripheral filling and a homogeneous nephrogram. Renal vein filling defects were a frequent feature.
早期急性排斥反应发生在肾同种异体移植术后2至10天，156例肾移植中有8例出现这种情况。8例患者中有4例发生了与活检无关的自发性肾破裂。病理上，有急性被动性充血，伴有肾小管坏死、静脉血栓形成和静脉周围淋巴组织增生区域。肾小球和动脉的免疫性损伤轻微。放射学表现为肾脏增大，叶间动脉和段动脉伸展，外周灌注减少，肾图均匀。肾静脉充盈缺损是常见特征。
