Two hundred one abdominal CT scans were performed in 93 patients who had undergone previous nephrectomy for renal cell carcinoma. Three had local recurrence and nine had metastatic lesions. Local recurrence and metastatic lesions were detected from 7 months to 6 years and 4 months after nephrectomy (median 2 years and 9 months). Local recurrent lesions were detected as masses in the vacant renal fossa. Metastatic lesions of the abdomen were seen in adrenal gland, liver, contralateral kidney, bone, etc. Administration of oral contrast material was useful to differentiate these recurrent lesions from intestine. It was important to fully understand the anatomical change after nephrectomy, and US might be especially helpful for evaluating the liver and contralateral kidney.
对93例因肾细胞癌行肾切除术的患者进行了201次腹部CT扫描。3例出现局部复发，9例出现转移灶。局部复发和转移灶在肾切除术后7个月至6年4个月被发现（中位时间为2年9个月）。局部复发病灶表现为肾窝空虚处的肿块。腹部转移灶可见于肾上腺、肝脏、对侧肾脏、骨骼等部位。口服对比剂有助于将这些复发病灶与肠道区分开来。充分了解肾切除术后的解剖变化很重要，超声对评估肝脏和对侧肾脏可能特别有帮助。
