Aim: To compare overall survival in patients with renal tumor with signs of renal cell carcinoma according to CT after surgical procedure and percutaneous ablation.

Methods: Our cohort included patients with tumor of renal cell carcinoma appearance on contrast enhanced CT treated with radical or partial nephrectomy or percutaneous ablation at the University Hospital Brno between 2010 and 2020. Overall survival, tumor size and localization, age, and gender were compared between patients with surgical resection and ablation. Among patients treated with ablation, the rate of complications after the procedure was analyzed in relation to tumor location and size, patient age, and the ablation method used.

Results: The retrospective study included 109 consecutive patients (70 % men) with 109 stage T1a tumor. The mean age of patients was 66.9 ± 11.9 years. Percutaneous ablation was used in 29 % (n = 32) of tumors, and surgical treatment in 71 % (n = 77). The mean age of patients indicated for ablation was higher than in the group indicated for surgery (71.8 vs. 64.9 years, p = 0.004). There was no statistically significant difference between ablation and resection in overall survival, gender and tumor location. No significant factor associated with complications of ablation procedures was found.

Conclusion: Percutaneous ablation is an alternative method of treating renal cell carcinomas in patients who are not candidates for surgery. There was no significant difference in overall survival between patients after ablation and surgery.
