Abstract:
The management and diagnosis of renal tumors have changed significantly over the last decade. Due to advances in imaging techniques, more than 50% of kidney tumors are discovered incidentally and many of them represent an early stage lesion. This has stimulated the development of nephron-sparing surgery and of the minimally invasive treatment options including ablative techniques, i.e., radiofrequency ablation (RFA) and cryoablation. The objective of the minimally invasive approach is to preserve the renal function and to lower the perioperative morbidity. RFA involves inducing the coagulative necrosis of tumor tissue. Being probably one of the least invasive procedures in kidney tumor management, RFA may be performed percutaneously under ultrasound (US), computed tomography (CT) or magnetic resonance (MR) guidance. Most of the studies show that the RFA procedure is efficient, safe and has a low complication rate. Due to the still limited data on the oncological outcome of RFA, the indication for this intervention remains limited to selected patients with small organ-confined renal tumors and contraindication to surgery or who have a solitary kidney. The aim of our study is to review the literature on RFA of kidney tumors.
Insights
Radiofrequency ablation (RFA) is a minimally invasive treatment for small kidney tumors, offering a safe and effective alternative to surgery. This review explores RFA
Area of Science:
- Urology
- Oncology
- Minimally Invasive Surgery
Background:
- Renal tumor diagnosis and management have evolved, with over 50% of kidney tumors now incidentally discovered due to advanced imaging.
- Early-stage lesions are increasingly identified, driving the development of nephron-sparing and minimally invasive treatments.
- Minimally invasive options, including radiofrequency ablation (RFA) and cryoablation, aim to preserve renal function and reduce perioperative morbidity.
Purpose of the Study:
- To review the current literature on the efficacy and safety of radiofrequency ablation (RFA) for renal tumors.
- To assess the role of RFA as a minimally invasive treatment option in kidney tumor management.
- To evaluate the indications and outcomes of RFA in selected patients with renal tumors.
Main Methods:
- Literature review of studies on radiofrequency ablation (RFA) for kidney tumors.
- Analysis of RFA procedures performed percutaneously under imaging guidance (ultrasound, CT, MR).
- Evaluation of data regarding RFA's efficiency, safety, complication rates, and oncological outcomes.
Main Results:
- Radiofrequency ablation (RFA) is an efficient and safe procedure for kidney tumor management with a low complication rate.
- RFA induces coagulative necrosis of tumor tissue, representing a minimally invasive approach.
- Studies indicate RFA is effective, but long-term oncological outcome data are still limited.
Conclusions:
- Radiofrequency ablation (RFA) is a viable, minimally invasive option for selected patients with small, organ-confined renal tumors.
- RFA is particularly indicated for patients with contraindications to surgery or those with a solitary kidney.
- Further research is needed to fully establish the long-term oncological effectiveness of RFA in renal tumor treatment.
