Conservative surgery for renal cell carcinoma.

The authors present their clinical experience in conservative surgery for renal cell carcinoma, which was performed in two cases of simultaneous bilateral tumours, in a case of neoplasm in solitary kidney, in two cases of cancers with damaged contralateral kidney and in two cases of association between cyst and small tumour. All patients are alive and without evidence of residual or recurrent malignancy with a followup ranging between 6 months and 7 years. The pros and cons of the various surgical solutions are discussed.
