Conservative treatment in renal cancer

— The aim of this study is to evaluate the role of conservative surgery in renal cancer. The more widespread use of imaging techniques, like ultrasound and CT, has led to the earlier diagnosis of small and asymptomatic tumours (T1-T2; diameter < 4 cm). Some Authors have therefore begun to perform conservative treatment, when there is a normal contralateral kidney, obtaining favourable and unhoped-for results, although radical surgery maintains its fundamental therapeutic role in this pathology.
