Objective: The aim of this study is to evaluate the outcome of ablation
therapy in our clinic for the treatment of patients with small renal
mass Materials and Methods: We retrospectively evaluated the technic and
follow-up data of 30 patients with 36 tumors who underwent
Radiofrequency Ablation (RFA) and Microwave Ablation (MWA) in our
clinic. Demographic data, ablation type, tumor characteristics,
peroperative and postoperative complications and treatment success of
the patients were evaluated. Results: A total of 36 tumors who underwent
ablation treatments, 23 were treated with RFA, 13 with MWA. The mean
tumor size was 28.9 ± 6.92 mm in RFA and 29.3 ± 7.70 mm in MWA. 12
(52.1%) of the RFA procedures were applied to the right kidney while 11
(47.8%) were applied to the left kidney. 6 (46.1%) of the MWA
procedures were performed on the right kidney and 7 (53.8%) on the left
kidney. Of the 36 tumors, 4 (11.1%) were located central and 32
(88.8%) were peripheral. Complications occurred in 2 patients. In one
of these patients, acute renal failure and urea creatinine were found to
be elevated. In the other patient, local pain was found in the ablation
side and minor bleeding was detected at the ablation site in USG. The
mean follow-up period was 49.6 ± 24.7 months in patients with RFA and
mean follow-up was 16 ± 8,05 months in MWA treatments. The overall
success in MWA administration was calculated as 76.9%, while the
overall success in RFA was 80%. Conclusion: Long-term oncologic
efficacy of RFA appears to be successful in the treatment of T1a renal
carcinomas. Further studies can be conducted to elucidate the influence
of MWA on long-term oncological outcomes.
