E.肾结石评分与Guy肾结石分级对经皮肾镜取石术(percutaneous nephroscope lithoipsy,PCNL)结石清除率预测的准确性。方法选择2015-01至2017-12在西安交通大学第二附属医院接受PCNL的患者146例,术前分别进行S. T. O. N. E.评分和Guy分级。术后统计结石清除率,分别计算S. T. O. N. E.评分和Guy分级的ROC曲线下面积,对比两种方法预测的准确性。结果结石清除率为73. 97%。S. T. O. N. E.肾结石评分预测PCNL术后结石清除率的准确性为74. 8%,最佳阈值为8. 5分,灵敏度为73. 7%,特异度为71. 3%; Guy分级预测PCNL术后结石清除率的准确性为71. 5%,最佳阈值为2. 5级,灵敏度为71. 1%,特异度为64. 8%。两种方法的ROC曲线下面积分别为0. 748和0. 715,无统计学差异。结论 S. T. O. N. E.评分与Guy分级均具有中等水平预测能力,均可用来评估PCNL术后结石清除率,两个方法的预测能力未见统计学差别。展开更多

For the inner world, heis calm towards the living environments, decisive when faced the emergency and persistent in dignity and morality. For the actions,he is active in seeking foods, brave in fighting with the enemies and gentle with his son. Finally, the conclusion is drawn that the fa-ther is a"Tough Guy".展开更多
