[One-stage cryoablation of two renal tumors]

The progressive development of medical technologies allowed the introduction of alternative methods of treatment of localized renal cell carcinoma with a tendency to organ-sparing approach. Cryoablation, radiofrequency ablation, and some experimental methods of treatment (microwave and laser ablation, therapy with high-intensity focused ultrasound) are referred to minimally invasive treatment of renal cell carcinoma. Cryoablation is highly effective alternative method of treatment of renal cell carcinoma. The main advantages of this technique are tumor visualization and formation of 'ice ball' in real time, fewer complications compared with other methods, as well as the possibility of cryotherapy in critically ill patients. Compared to other ablative technologies, cryoablation is followed by low percentage of redo treatment and good intermediate oncological results. We described the experience of one-stage cryoablation of two kidney tumors in this report.
