Percutaneous Ablation of Localized Renal Masses: An Updated Review

With readily available cross-sectional imaging, asymptomatic localized renal masses (LRMs) are often incidentally found. The standard management for LRM has been surgical resection, however, detection of masses that are benign or with low metastatic risk has led to interest in minimally invasive alternatives such as percutaneous thermal ablation (TA) or active surveillance. The increasing adoption of TA heralds more data and novel uses. Our previous article by Mershon et al. highlighted the safety and efficacy of TA for treatment of LRMs in select patients [1]. In this presentation, we update that work and discuss new frontiers for TA including patient selection, procedural improvements, and outcomes.
