NEPHRON SPARING SURGERY FOR RENAL TUMORS: INDICATIONS, TECHNIQUES AND OUTCOMES

Purpose: A contemporary review of the indications, techniques and outcomes is presented for nephron sparing approaches to solid renal masses, emphasizing their role for the treatment of renal cell carcinoma. We also reviewed the evolving role of minimally invasive forms of parenchymal sparing renal surgery.Materials and Methods: MEDLINE and CANCERLIT computerized literature searches, and manual bibliographic reviews were performed to identify published peer reviewed articles pertaining to nephron sparing surgery or partial nephrectomy from 1980 to 2000. Pertinent articles were collated and reviewed.Results: Nephron sparing surgery is increasingly being used to treat patients with solid renal lesions. The technical success rate of nephron sparing surgery is excellent, and operative morbidity and mortality are low. For renal cell carcinoma long-term cancer-free survival is comparable to that after radical nephrectomy, particularly for low stage disease. The overall incidence of local recurrence is low at 0%...
