Abstract
Purpose of reviewSmall renal masses suspected to be malignant have little potential for metastasis and disease-related mortality. Surgery remains the standard care but represents overtreatment in many cases. Percutaneous ablative technique, especially thermal ablation has emerged as a valid alternative.Recent findingsThe increased availability of cross-sectional imaging has led to a large number of incidentally detected small renal masses (SRMs), many of which are of low grade and exhibit indolent behaviour. Since 1996, ablative techniques such as cryoablation, radiofrequency ablation, and microwave ablation have gained widespread acceptance for treatment of SRMs in patients who are not surgical candidates. In this review article, we provide an overview of each of the commonly used percutaneous ablative treatments for SRMs and summarize the current literature regarding the advantages and disadvantages of each technique.SummaryAlthough partial nephrectomy (PN) represents the standard treatment of SRMs, Thermal ablation techniques have been increasingly used showing acceptable efficacy, low complication rate, and equivalent survival.
