OBJECTIVE: This study aims 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 @entity1358 @entity1 . METHODS: A total of 52 @entity1 with @entity1358 were enrolled. They all had retroperitoneal partial nephrectomy. Their clinical data was 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 better than those of the original R.E.N.A.L. nephrometry score system. Compared with low degree of operation difficulty, @entity1 with medium and high degree of operation difficulty had significantly higher levels of operative time, warm @entity63 time, and intraoperative @entity190 (P < 0.05). And, the levels of operative time, warm @entity63 time, and intraoperative @entity190 in @entity1 with high degree were significantly higher than those in @entity1 with medium degree (P < 0.05). CONCLUSIONS: The modified R.E.N.A.L. nephrometry score system has a good effect in evaluating the operation difficulty of retroperitoneal partial nephrectomy.
