Objective: to compare the predictive value of RENAL, PADUA, C-index nephrometry score systems according to projection of complexity  of operative measure in terms of warm ischaemic time, extent of blood loss and rate of postoperative complications.Materials and methods. Information for the research was collected from 314 patients with localized kidney cancer, who had laparoscopic partial nephrectomy from January 2012 to May 2017. In 210 (66.8 %) cases, in addition to the routine examinations, 3D modelling and operative measure planning were carried out. The average tumor volume of the patients was equal to 62.5 ± 33.5 mm3. All patients before  the operation were estimated the complexity of operative measure on the nephrometry score systems: PADUA, RENAL, C-index. The average sum of balls according to scale RENAL – 7.56 ± 1.12, on scale PADUA – 7.98 ± 1.55, on scale C-index – 2.76 ± 1.14. Then in retrospect by the method of logistic regression analysis was determined predictive value of RENAL, PADUA, C-index nephrometry score systems for prediction of warm ischaemic time, duration of operative measure, extent of intraoperative blood loss and possibility of rate of postoperative complications.Results. In 265 (84.4) cases transperitoneal approach was perfomed and in 49 (15.6 %) cases it was retroperitoneal approach. The average time of laparoscopic partial nephrectomy is 140.15 ± 55.8 min, the average time of ischaemic warm is 13.35 ± 7,65 min. The average extent of blood loss during the laparoscopic partial nephrectomy is 291.95 ± 196.5 ml. Intraoperative complications were found in 8 (2.54 %) cases. Postoperative complications were estimated according to the Clavien–Dindo classification of surgical complications and were found in 31  (9.9 %) cases, among them 12 (3.8 %) patients had surgical complications. The index of the RENAL nephrometry scoring system had the highest predictive value in the multivariant analysis for warm ischaemic time, extent of intraoperative blood loss and possibility of development after complications (p = 0.049; 0.028; 0.046). None of indices were significant for multivariant analysis of prognosis the duration of laparoscopic partial nephrectomy. The indices  of the RENAL (p = 0.032) and C-index (p = 0.040) nephrometry score systems were significant for univariate analysis of prognosis the duration of the laparoscopic partial nephrectomy.Conclusion. The usage of RENAL, PADUA, C-index nephrometry score systems is useful for the prediction of warm ischaemic time, extent  of blood loss, duration of operative measure and possibility of rate of postoperative complications at laparoscopic partial nephrectomy. According to our data the index of RENAL nephrometry scoring system has the highest predictive value. Applications of 3D modelling for counting nephrometry indices in preoperative period makes the process of counting balls easier on all three nephrometry score systems.
