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 T1 renal cell carcinoma patients. METHODS:
A total of 52 patients with T1 renal cell carcinoma 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, patients with medium and high degree of operation
difficulty had significantly higher levels of operative time, warm ischemia time,
and intraoperative blood loss (P < 0.05). And, the levels of operative time, warm
ischemia time, and intraoperative blood loss in patients with high degree were
significantly higher than those in patients 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.
