Abstract：
Objective: Our study aimed to evaluate the success rate of ESWL and identify relevant treatment-specific factors affecting treatment outcomes, as well as to assess the accuracy of the updated Triple D scoring system and compare it with older systems. Material and Methods: A prospective study of 71 patients who received ESWL treatment for renal stones that were 5-15 mm in size was completed. The patient having no residual stones or residual stones lesser than 4 mm after ESWL was identified as a treatment success. Univariate and multivariate logistic regression and ROC curves were used to identify important factors for treatment outcomes. Results: Successful treatment was achieved for 66.2% of patients. The stone volume (SV), mean stone density (MD), and delivered power to the stone volume unit ratio (SMLI/SV) were defined as the most critical factors influencing ESWL success. An updated Triple D score system with a, SMLI/SV ratio could be an alternative to older systems and reach an even higher accuracy. A limitation of this study is the limited sample size due to the COVID-19 pandemic. Conclusions: Our results show that the three factors that most influence the success of ESWL are the stone size, mean stone density, and SMLI/SV ratio. Based on this, we present a simple updated triple D score system to predict ESWL success, which could be implemented in future clinical practice.
摘要：
目的：我们的研究旨在评估ESWL的成功率并确定影响治疗结果的相关治疗特异性因素。以及评估更新的TripleD评分系统的准确性，并将其与较旧的系统进行比较。材料和方法：完成了一项对71例接受ESWL治疗的5-15mm大小的肾结石患者的前瞻性研究。ESWL后无残余结石或残余结石小于4mm的患者被确定为治疗成功。使用单变量和多变量逻辑回归和ROC曲线来确定治疗结果的重要因素。结果：66.2％的患者获得了成功的治疗。石头体积（SV），平均石材密度（MD），和发射功率与结石体积单位比（SMLI/SV）被定义为影响ESWL成功的最关键因素。更新的三D评分系统，SMLI/SV比可以是旧系统的替代方案并且达到甚至更高的精度。这项研究的局限性在于，由于COVID-19大流行，样本量有限。结论：我们的结果表明，影响ESWL成功的三个因素是结石大小，平均石材密度，和SMLI/SV比。基于此,我们提出了一个简单的更新的三重D评分系统来预测ESWL的成功，这可以在未来的临床实践中实施。
