Which technique is commonly selected for treating renal tumors?

Radiofrequency ablation (RFA) is commonly selected for treating renal tumors due to its effectiveness and minimally invasive nature. This technique utilizes high-frequency radio waves to generate heat, which destroys cancerous tissue while minimizing damage to surrounding healthy structures. RFA has been shown to provide good outcomes for patients with small renal tumors, often in cases where surgical options may not be ideal due to the patient's overall health or tumor size.

The precision of RFA allows for targeted treatment, making it a suitable option for tumors located in challenging anatomical positions. Additionally, it is generally associated with shorter recovery times, lower complication rates, and can often be performed on an outpatient basis, which further enhances its appeal for treating renal tumors.

While other techniques, such as cryoablation and microwave ablation, are also used for renal tumors, radiofrequency ablation stands out in terms of established efficacy and clinical experience, particularly for certain types of renal masses.
