[Application of nephrometry for choice of the treatment tactics in patients, suffering nephrocellular cancer].

Most significant nephrometric parameters, impacting the operative procedure choice, basing on analysis of examination and treatment of 903 patients, suffering localized nephrocellular cancer (NCC), were determined a residual volume of kidney parenchyma, maximal size and localization of tumor. The authors elaborated the estimation system for tumor affection of kidney (NCIU-nephrometry), what give possibility to determine the tactics of operative treatment of NCC. While localization of tumor in the kidney pole or its lateral segment a threshold value of the functioning parenchyma volume, in which the conduction of resection of kidney (RK) is indicated, must be over 55%. While localization of tumor in the kidney medial segment the indication for RK is a maximal size of tumor up to 4 cm. Introduction of the elaborated system into clinical practice would permit to make objective indications for RK and nephrectomy conduction.
