[Conservative surgery of kidney adrenoma]

Adenomas of the kidney are often tumors of doubtful dignity because the histopathological criteria are unclear and, moreover, the preoperative diagnosis lacks complete reliability. As a result, the clinician frequently has problems deciding on conservative surgery. This is demonstrated in the light of 6 cases of renal adenoma. The surgical management of these tumors depends on exact classification of their dignity by the pathologist. Proposals on the subject are put forward and discussed.
