Ultrasonic examination of renal transplants with special attention to the parenchymal echo pattern has been undertaken in 43 patients. In the normal renal transplant, the pyramids, cortex and renal sinus can be distinguished. Renal transplant rejection is manifested by swelling and decreased echogenicity of the pyramids and hyperechogenic cortex. In addition, large anechoic areas due to hemorrhagic infarcts and necrosis are seen. In long-standing rejection, a normal or small-sized kidney with an irregular intrarenal echo pattern is observed. In 13 cases of acute tubular necrosis, none of the above appearances could be demonstrated. Serial ultrasonic scans are essential to reveal evolutionary changes of the rejection process.
对43例患者进行了肾移植的超声检查，特别关注实质回声模式。在正常肾移植中，可以区分肾锥体、皮质和肾窦。肾移植排斥反应表现为肾锥体肿胀、回声减低以及皮质回声增强。此外，可见因出血性梗死和坏死导致的大无回声区。在长期排斥反应中，观察到肾脏正常或体积较小，肾内回声模式不规则。在13例急性肾小管坏死病例中，未发现上述表现。连续超声扫描对于揭示排斥反应过程的演变至关重要。
