Abstract：Objective: To investigate the application of the modified R.E.N.A.L. nephrometry score system in evaluating the operation difficulty of retroperitoneal partial nephrectomy in T1 renal cell carcinoma patients. Methods: A total of 52 patients with T1 renal cell carcinoma were enrolled. They all underwent retroperitoneal partial nephrectomy, and the clinical data were retrospectively analyzed. R.E.N.A.L. nephrometry score system was modified based on the features of retroperitoneal partial nephrectomy. The specificity, sensitivity and Youden index were compared between R.E.N.A.L. nephrometry score system and the modified R.E.N.A.L. nephrometry score system. The effect of the modified R.E.N.A.L. nephrometry score system on perioperative outcomes was analyzed. Results: Three degrees of operation difficulty were defined by the modified R.E.N.A.L. nephrometry score system, which included the low, medium and high degree of operation difficulty. The specificity, sensitivity and Youden index of the modified R.E.N.A.L. nephrometry score system were higher than those of the original R.E.N.A.L. nephrometry score system. The degrees of operation difficulty defined by the modified R.E.N.A.L. nephrometry score system showed a significant correlation with the operative time, warm ischemia time, and intraoperative blood loss (P<0.05).Conclusions:The modified R.E.N.A.L. nephrometry score system has a good efficacy in evaluating the operation difficulty of retroperitoneal par tial nephrectomy.
