Objectives

Narrative objectives1

Percutaneous ablation for small renal cell carcinomas includes radiofrequency ablation and cryotherapy, both of which are known to be useful and safe treatments. However, it is still unclear which is the better treatment, which should be used differently, or whether they are still equivalent. This study will provide direction in choosing between radiofrequency ablation and cryotherapy for small renal tumors.

Assessment

Primary outcomes

CT or MRI scans are performed before and periodically for two years after treatment to determine the effectiveness of treatment. Dynamic examinations using contrast media should be performed whenever possible, unless there are problems such as allergies or renal impairment.

Key secondary outcomes

Pre- and post-operative assessment of renal function, inflammatory response, pain, blood pressure and neurological symptoms, etc at regular intervals
