Update on the management of T1 renal cortical tumours.

There are a range of treatment strategies for the management of patients with small incidental renal cortical tumours including active surveillance, radiofrequency ablation, cryotherapy, radical nephrectomy and partial nephrectomy. A large number of such tumours are benign and might therefore be over-treated with radical nephrectomy. There are emergent short-term oncological and clinical outcomes for cryotherapy and radiofrequency ablation, and recent studies have illustrated the benefits of partial nephrectomy for minimizing the risk of progression to chronic kidney disease. The outcomes of these different treatment methods are discussed.
