OBJECTIVES: To evaluate the justification of routine removal of ipsilateral adrenal gland as part of radical nephrectomy for renal cell carcinoma (RCC). METHODS: The medical records, pathologic specimens, and computed tomographic (CT) scans of 77 patients who underwent radical nephrectomy and ipsilateral adrenalectomy for RCC were reviewed. Comparison was made between radiologic analysis and pathologic findings regarding involvement of the adrenal gland. RESULTS: The size of the renal tumor varied between 3.5 and 19 cm (mean 8.5). The upper pole was involved in 45%, the lower pole in 28%, and the midpole in 18% of the patients, and in 9% the whole kidney was involved by the tumor. Histologic findings showed that 72 (94%) of the 77 adrenal glands were normal and 70 of these were normal on CT as well. Two adrenal glands involved by metastases showed heterogeneous contrast entrancement on CT. The benign lesions of three adrenal glands were also picked up as abnormal on CT. In 2 patients adrenal glands could not be visualized on CT because of a paucity of retroperitoneal fat. CONCLUSIONS: Adrenalectomy with nephrectomy may not be performed in patients with RCC in whom CT demonstrates normal adrenal glands. In patients with adrenal abnormality on CT, magnetic resonance imaging can separate metastases from incidental benign adrenal adenoma, further reducing the number of patients requiring removal of the adrenal gland.
