Abstract
Patients (25) 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 1 hematoma and 1 retroperitoneal abscess. CT could be useful in following up selected patients after nephrectomy.
