Modern imaging modalities increase the detection of small (<or=4 cm) renal tumors, of which about 20% are benign. As a result, minimal invasive treatments, such as radiofrequency ablation and cryotherapy, and surveillance strategies are gaining popularity. Information that would be helpful when choosing the most appropriate management strategy for this patient group could be obtained from pretherapeutic image-guided biopsy.
