AbstractThe management of renal tumors has evolved rapidly over the last two decades, with the ascendance of nephron-sparing surgery (NSS), largely spurred by the increased incidental detection of small renal masses (SRMs) and evidence that preservation of renal parenchyma reduces the risk of chronic kidney disease. The field of NSS itself has advanced beyond the standard of open partial nephrectomy, with the application of minimally invasive techniques, such as laparoscopy and thermal ablation. Energy-based ablative therapies, which include cryoablation and radiofrequency ablation, are associated with reduced morbidity and represent a nascent but promising alternative to surgical extirpation in the treatment of SRMs. However, thermal ablation is associated with a higher rate of local tumor recurrence when compared with surgical excision, indicating that salvage therapy will be a necessity for some patients. With recent studies indicating that surgical excision of previously ablated kidneys can be complicated by significant fibrosis, clinicians who advocate thermal ablation must be cognizant of the sequelae of this treatment modality and versed on the potential difficulties associated with salvage surgery. We provide, herein, an assessment of the efficacy and limitations of primary thermal ablation and strategies for salvage treatment of local recurrence in this growing patient population.
