The article describes the clinical observation of 128 patients with an established clinical diagnosis – localized renal cell carcinoma (T1N0M0) and the use of the developed complex of nephrometric assessment of kidney tumor according to multispiral computed tomography with the aim of planning organ-preserving surgery and removal of a kidney tumor by classical resection or enucleoresection. The results of a statistical analysis of the influence of the node size indicator on the results of operations are demonstrated. It was found that the indicator of the maximum size of the neoplasm (OR = 15,27, 95 % CI = 10,68–21,83, p = 0,007), as well as the localization of the node, density characteristics and type of tumor growth, the state of the pseudocapsule and compression of the kidney sinus, corresponds to one of the main criteria for substantiating the technical feasibility of enucleoresection.
