ABSTRACT
Organ-sparing approaches for renal cell carcinoma (RCC) are the treatment of choice when the incidence of localized RCC is bilateral, or in a solitary functioning kidney. In such patients, nephron-sparing surgery allows complete surgical excision of the primary tumor while sufficient renal parenchyma is preserved to avoid renal replacement therapy1,2. The indications for partial nephrectomy have been expanded to include the patient with localized RCC and a functioning opposite kidney, when that kidney is involved with a disorder that might cause progressive renal functional impairment in the future.
