1. The main advantage of Bioplasm nls software-research at pre-surgery examination of patients with RC was reliable diagnostics of a primary tumor spreading into structural elements of cavitary system, paranephric fat and kidney’s capsule, especially in diagnostics of thrombogenesis (invasion) in renal vein or inferior vena cava.

2. On the basis of Bioplasm nls software-study we noted a tendency to increasing of stages of a main disease and therefore increasing of number of radical surgical interventions. At the same time differentiation of a 1st and a 3rd stages of RC is possible, when it is difficult and sometimes impossible on the basis of ultrasound study results.

3. In some cases we carried out differential diagnostics of malignant or benign character of revealed neoplasm growth using SEA, which was confirmed by biopsy in 98.2% of cases.
