[Conservative therapy of renal parenchymal neoplasia]

We review our overall experience in 1375 patients, who underwent surgery for renal cell carcinoma in the Departments of Urology of Brescia and Bergamo from 1983 to 1996. 185 (13.4%) patients had nephron-sparing surgery: imperative procedure was performed in 74 cases, while an elective surgery was done in 111 patients. Three years minimal follow up was considered in order to evaluate the outcome of surgical treatment in 48 patients who underwent imperative nephron-sparing surgery and in 73 with an elective procedure. Disease specific survival was 80.8% in the first group and it was 97% in the latter.
