Bilateral simulataneous kidney tumors of dissimilar cell type: a case report with emphasis on operative approach

The first reported case of bilateral, simultaneous renal tumors of dissimilar cell type treated in a living patient is presented. The operative approach is outlined to support single in situ operative procedures in young patients. A second look laparotomy at 1 year and a creatinine clearance of 60 ml. per minute at 2 years substantiate our enthusiasm for this approach to bilateral renal lesions.
