Abstract

Objectives: Evaluation of the validity of the Quadruple-D score in the prediction of success in pediatric stone disease.

Materials and methods: Of the 292 children treated with SWL between 2007 and 2023, a total of 158 children who had adequate follow-up data and evaluated with non-contrast computed tomography before SWL, were included in the study. Parameters were calculated for each of the stone volume (SV), skin-to-stone distance (SSD), stone density (SD) and stone location (SL) variables. Receiver operator characteristic analysis was used to set cut-off values. Quadruple-D scores were calculated, and success rates were determined for each score. Stone-free status was determined as complete clearance after three months of final SWL.

Results: The median age of the study group was 8 (range 1 to 16). One hundred and one of the 158 (64%) children had stone-free status. Mean SV, SSD and SD values were significantly higher in SWL failed group than stone-free group after detecting cutoff values of 150 mm³, 6.7 cm, and 540 HU, respectively. Stone-free rates were detected as 19.6%, 24.7%, 37.2%, 76.2%, and 90.2% with the Quadruple-D scores of 0, 1, 2, 3 and 4 points.

Conclusions: Quadruple-D scoring system can further improve Triple-D scoring system by adding stone position parameter to clarify SFR with a simple and easy calculation. We believe that the Quadruple-D score will have better clinical significance than the Triple-D scoring system in predicting the success of SWL in children.

小儿肾结石体外冲击波碎石术成功率的四项D评分。

目的评估Quadruple-D评分在预测小儿结石病成功率方面的有效性：在2007年至2023年期间接受过SWL治疗的292名儿童中，共有158名儿童在接受SWL治疗前接受了非对比计算机断层扫描评估，并有足够的随访数据。研究人员计算了结石体积（SV）、皮肤到结石的距离（SSD）、结石密度（SD）和结石位置（SL）等变量的参数。采用接收者操作特征分析法设定截断值。计算了四重 D 评分，并确定了每个评分的成功率。最终SWL三个月后完全清除为无结石状态：研究组的中位年龄为 8 岁（1 至 16 岁不等）。158名儿童中有101名（64%）处于无结石状态。SWL失败组的平均SV值、SSD值和SD值分别为150 mm3、6.7 cm和540 HU，明显高于无结石组。在四重-D 评分为 0、1、2、3 和 4 分时，无结石率分别为 19.6%、24.7%、37.2%、76.2% 和 90.2%：四重-D 评分系统通过增加结石位置参数来明确 SFR，计算简单易行，从而进一步改进了三重-D 评分系统。我们相信，在预测儿童 SWL 成功率方面，四重-D 评分将比 Triple-D 评分系统具有更好的临床意义。

期刊介绍： Official Journal of the International Urolithiasis Society The journal aims to publish original articles in the fields of clinical and experimental investigation only within the sphere of urolithiasis and its related areas of research. The journal covers all aspects of urolithiasis research including the diagnosis, epidemiology, pathogenesis, genetics, clinical biochemistry, open and non-invasive surgical intervention, nephrological investigation, chemistry and prophylaxis of the disorder. The Editor welcomes contributions on topics of interest to urologists, nephrologists, radiologists, clinical biochemists, epidemiologists, nutritionists, basic scientists and nurses working in that field. Contributions may be submitted as full-length articles or as rapid communications in the form of Letters to the Editor. Articles should be original and should contain important new findings from carefully conducted studies designed to produce statistically significant data. Please note that we no longer publish articles classified as Case Reports. Editorials and review articles may be published by invitation from the Editorial Board. All submissions are peer-reviewed. Through an electronic system for the submission and review of manuscripts, the Editor and Associate Editors aim to make publication accessible as quickly as possible to a large number of readers throughout the world.
