Objectives: To evaluate the feasibility, the efficiency and the safety of percutaneous micro-waves (MW) treatment of small renal carcinomas (RC) performed under computed tomography (CT) guidance.
Methods: 31 patients presenting one or more RC were treated under CT guidance. A CT examination was performed at 1 and 6 months to evaluate the results of the treatment.
Results: 42 tumors ranging from 10 to 48 mm in diameter (mean: 25.6 mm) were treated. In 90 % cases, the treatment was considered as a success (absence of residue or recurrence at 6 months). At 1 month, 4 residual tumors were observed and retreated with a completed removal obtained after the second session. At 6 months one recurrence was observed and retreated with a completed success. A perirenal hematoma for a patient under anticoagulant treatment was noted.
Conclusion: Percutaneous ablation of RC by MW under CT guidance is an efficient and safe technique.
