The management of small renal masses is a dynamic and evolving process. Twenty years ago, the mainstay management for small renal masses was radical nephrectomy. This resulted in over-treatment of many patients. It has become evident that radical nephrectomy is a significant risk factor for the development of chronic renal disease. More recently, chronic renal insufficiency has been associated with increased risk of cardiovascular events, hospitalizations and mortality. Patients undergoing renal preservation, e.g., nephron sparing surgery, have better overall quality of life than patients undergoing radical nephrectomy.
