Conservative surgery for renal cell carcinoma.
Conservative surgery was initially limited to patients with localized RCC present bilaterally or in a solitary kidney, in whom radical nephrectomy would necessitate immediate renal replacement therapy. Today, the widespread use of abdominal ultrasound as screening modality in patients with nonspecific or unrelated symptoms allows the detection of renal parenchymal tumors rarely seen before: asymptomatic, small and unilateral neoplasms, often surrounded by a thick and complete pseudocapsule. Global renal function and contralateral kidney are usually normal and the patients show good performance status. For these reasons and because of the generally good results of the first experiences, several authors advocate conservative surgery as an elective indication. Recently, some studies have reported promising results with this approach. On the other hand, some controversial issues persist (multifocality of RCC, low risk of local relapse and renal failure after radical surgery, low incidence of tumor in the contralateral kidney) reducing the opportunity to perform nephron-sparing surgery when the contralateral kidney is normal. In the present study, we report our experience of nephron-sparing surgery for RCC and we review the current and international opinion concerning this treatment.
