Twenty-five patients were examined by computed tomography (CT) after nephrectomy. CT was useful in the detection of postoperative complications and local recurrence of tumor. Ultrasound was difficult because of rib artifacts or bowel gas, and a fluid-filled bowel often simulated tumor: oral contrast material was useful during CT. Local recurrence was demonstrated by CT in 8 patients in whom it was clinically suspected. Recurrent tumor was simulated by scarring in 3 cases and by an accessory or residual spleen in 2. Operative complications included one hematoma and one retroperitoneal abscess. CT could be useful in following up selected patients after nephrectomy.
25例患者在肾切除术后接受了计算机断层扫描（CT）检查。CT有助于检测术后并发症和肿瘤局部复发。由于肋骨伪影或肠道气体干扰，超声检查存在困难，且充满液体的肠管常类似肿瘤：CT检查时口服对比剂很有用。临床怀疑有局部复发的8例患者经CT证实存在复发。3例患者的复发性肿瘤被瘢痕组织模拟，2例被副脾或残余脾模拟。手术并发症包括1例血肿和1例腹膜后脓肿。CT可用于肾切除术后部分患者的随访。
