肾测量评分外部验证评估腹腔镜肾部分切除术的围手术期参数在一个单一的机构
External validation of RENAL nephrometry score to assess the perioperative parameter for laparoscopic partial nephrectomy in a single institution

Abstract
Objective
摘要
目的
RENAL nephrometry score (RNS) has been proposed as an anatomical classification system for renal masses to investigate the influence on perioperative outcomes and complications. The aim of this study was to assess the system for external validation on laparoscopic partial nephrectomy (LPN).
肾测量评分（RNS）已经提出了探讨围手术期预后和并发症的影响肾肿块的解剖分类系统。本研究的目的是评估在腹腔镜肾部分切除术的外部验证系统（LPN）。

Materials and methods
材料与方法
The single-surgeon database enrolled patients who had undergone LPN from December 2008 to September 2013. Renal tumors were divided into low-, intermediate-, and high-complexity groups according to the RNS sum score. We reviewed perioperative outcomes including operation time (OT), length of stay (LOS), estimated blood loss (EBL), ischemia time (IT), conversion to open surgery rate, estimated glomerular filtration rate (eGFR), and complications. We also assessed the individual characteristic parameters in the present study. The data was collected retrospectively and analyzed by SPSS Statistics 18.
single-surgeon数据库登记病人经历了LPN从2008年12月到2013年9月。肾肿瘤患者分为低、中、高复杂度的组根据RNS总分。我们回顾了包括手术时间（OT）围手术期的结果，住院时间（LOS），估计失血量（EBL），缺血时间（它），中转开腹率，估算的肾小球滤过率（eGFR），和并发症。我们还评估了在本研究中的各个特征参数。对采集到的数据进行回顾性分析，通过SPSS统计分析18。

Results
结果
A total of 53 patients were enrolled, with a mean age of 49.2 years. Of the 53 patients, there were 15 low-, 26 intermediate-, and 12 high-RNS lesions. Significant difference was observed in major complication rate between low- and high-score groups. Both radius and nearness were independent predictors of major complication rate. Also, there was a significant difference in eGFR change between low- and high-complexity tumor group. Fair degree correlation was found between IT and eGFR change (p < 0.05).
总共有53例患者参加，平均年龄为49.2岁。在53例患者中，有15个小，26中，12高RNS病变。低和高分组之间主要并发症发生率有显著性差异。半径与亲近是主要并发症发生率的独立预测因子。此外，低和高复杂度的肿瘤组之间的表皮生长因子受体的变化有一个显着的差异。它与表皮生长因子受体改变（P＜0.05）呈显著正相关。

Conclusion
结论
The RNS is a valuable tool to categorize renal tumors based on the anatomic features when predicting major complication rate. The renal function can be affected after a high-complexity tumor surgery is performed. Also, IT is a fair degree correlation factor of the renal function loss.
RNS是肾肿瘤的解剖特点的基础上，预测的主要并发症的发生率进行分类的一个有价值的工具。在一个高复杂度的肿瘤手术后，肾功能可以受到影响。此外，它是一个公平的程度相关因素的肾功能损失。
