Abstract:
The 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.
Insights
Thermal ablation offers a less invasive option for small renal masses (SRMs), but recurrence necessitates salvage therapy. Surgeons must understand potential complications when treating previously ablated kidneys.
Area of Science:
- Urology
- Oncology
- Minimally Invasive Surgery
Background:
- Nephron-sparing surgery (NSS) is the standard for small renal masses (SRMs), driven by incidental detection and kidney function preservation.
- Minimally invasive techniques, including laparoscopy and thermal ablation (cryoablation, radiofrequency ablation), have advanced NSS.
- Thermal ablation presents a promising, less morbid alternative to surgical extirpation for SRMs.
Purpose of the Study:
- To assess the efficacy and limitations of primary thermal ablation for SRMs.
- To outline strategies for salvage treatment of local recurrence after thermal ablation.
- To inform clinicians about potential challenges in salvage surgery for previously ablated kidneys.
Main Methods:
- Review of current literature on thermal ablation for SRMs.
- Analysis of recurrence rates associated with thermal ablation versus surgical excision.
- Evaluation of surgical outcomes for previously ablated kidneys requiring salvage procedures.
Main Results:
- Thermal ablation is associated with reduced morbidity compared to traditional surgery.
- Local tumor recurrence rates are higher with thermal ablation than with surgical excision.
- Salvage surgery after thermal ablation may be complicated by significant renal fibrosis.
Conclusions:
- Thermal ablation is an effective primary treatment for SRMs, but requires vigilance for recurrence.
- Salvage therapy is often necessary after thermal ablation due to higher recurrence rates.
- Understanding the implications of renal fibrosis is crucial for successful salvage surgery following thermal ablation.
