The aim of the current study was to compare Guy's score and STONE score in predicting the success and complication rate of percutaneous nephrolithotomy (PCNL).
A total of 445 patients were included in the study between July 2015 and December 2016. The patients were given STONE score and Guy's Stone Score (GSS) grades based on CT scan done preoperatively and intra- and post-operative complications were graded using the modified Clavien grading system. The PCNL were done by a standard technique in prone positions.
The success rate in our study was 86.29% and both the GSS and STONE score were significantly associated with a success rate of the procedure. Both the scoring systems correlated with operative time and postoperative hospital stay. Of the total cases, 102 patients (22.92%) experienced complications. A correlation between STONE score stratified into low, moderate, and high nephrolithometry score risk groups (low scores 4-5, moderate scores 6-8, high scores 9-13), and complication was also found ( = 0.04) but not between the GSS and complication rate ( = 0.054).
Both GSS and STONE scores are equally effective in predicting success rate of the procedure.
本研究旨在比较盖伊评分和STONE评分在预测经皮肾镜取石术（PCNL）成功率和并发症发生率方面的效果。
2015年7月至2016年12月期间，共有445例患者纳入本研究。根据术前CT扫描结果对患者进行STONE评分和盖伊结石评分（GSS）分级，并使用改良的Clavien分级系统对手术中和术后并发症进行分级。PCNL采用标准俯卧位技术进行。
本研究中的成功率为86.29%，GSS和STONE评分均与手术成功率显著相关。两种评分系统均与手术时间和术后住院时间相关。在所有病例中，102例患者（22.92%）出现并发症。将STONE评分分为低、中、高结石测量评分风险组（低分4 - 5分、中分6 - 8分、高分9 - 13分）后，发现其与并发症之间存在相关性（= 0.04），但GSS与并发症发生率之间不存在相关性（= 0.054）。
GSS和STONE评分在预测手术成功率方面同样有效。
