Renal tumor ablation is a function of patient selection and technique—Not the ablation technology


  • See referenced original article on pages 2671–80, this issue.


In this issue, although the authors of a meta-analysis of the existing published literature on cryoablation and radiofrequency ablation (RFA) acknowledge multiple shortcomings in their data, they nevertheless present a conclusion that suggests the superiority of cryoablation over RFA. However, differences in ablation techniques and patient selection may influence the rates of tumor retreatment and disease recurrence, making it difficult to reach any conclusion regarding the superiority of 1 ablation technique over another.
