摘要

目的 探讨改良首尔国立大学肾结石复杂性评分(S-ReSC)、肾结石复杂性评分(R.I.R.S.)及腔内泌尿外科学会临床研究办公室肾镜测量列线图(CROES)评分在预测输尿管软镜联合可弯曲负压吸引鞘治疗肾结石术后结石清除率中的价值。方法 选取2022年12月-2024年4月于巴中市中心医院接受行输尿管软镜联合可弯曲负压吸引鞘治疗的肾结石患者200例作为研究对象,术后1个月经腹部计算机断层扫描(CT)评估分为结石残留组(n=38)和无结石残留组(n=162)。采用Pearson分析各评分间相关性,采用二元logistic回归筛选独立危险因素,受试者工作特征(ROC)曲线评估预测效能,Delong检验比较曲线下面积(AUC)差异。结果 相比无结石残留组,结石残留组改良S-ReSC、R.I.R.S.评分显著升高,CROES评分显著降低(P<0.05)。改良S-ReSC与R.I.R.S.评分正相关(P<0.05),CROES评分与前两者负相关。鹿角形结石、结石最大直径及CT值升高、改良S-ReSC与R.I.R.S.评分升高,CROES评分降低是术后结石残留的独立危险因素(P<0.05)。ROC曲线显示R.I.R.S.评分AUC为0.855表现最佳,且联合预测AUC达0.950。结论 R.I.R.S.评分预测输尿管软镜联合可弯曲负压吸引鞘治疗肾结石术后结石残留效能最佳,尤其适用于复杂结石。将结石特征与三种评分联合可提升结石清除率的预测效能,为临床术前评估及个体化治疗提供参考。

Abstract

Objective To investigate the significance of modified Seoul National University Renal Stone Complexity score(S-ReSC),renal stone complexity score(R.I.R.S.),and Clinical Research Office of the Endourological Society Nephrolithometric Nomogram(CROES)score in predicting the stone-clearance rate(SFR)after ureteroscopy combined with flexible negative pressure suction sheath in the treatment of kidney stones. Methods A total of 200 patients with kidney stones treated in our hospital during Dec.2022 and Apr.2024 were selected.According to abdominal CT evaluation 1 month after surgery,the patients were divided into the residual group(n=38)and the non-residual group(n=162).The relationship between the scores was assessed with Pearson correlation,the independent risk factors were identified with binary logistic regression,the predictive efficacy was evaluated with the receiver operating characteristic(ROC)curves,and the difference in the area under the ROC curves(AUCs)was compared with the Delong test. Results Compared with the non-residual group,the residual group had significantly higher modified S-ReSC and R.I.R.S.,but significantly lower CROES score(P<0.05).Modified S-ReSC was positively correlated with R.I.R.S.(P<0.05),while CROES score was negatively correlated with S-ReSC and R.I.R.S.Staghorn stones,maximum stone diameter,elevated CT values,increased S-ReSC and R.I.R.S.,and decreased CROES score were independent risk factors for postoperative stone residual(P<0.05).ROC curves showed the optimal AUC of R.I.R.S.was 0.855,and the optimal AUC of combined prediction was 0.950. Conclusion The R.I.R.S.has the best efficacy in predicting postoperative stone residual,especially for complex stones.The combination of stone characteristics and the three scoring systems can improve the prediction efficiency,and provide reference for preoperative evaluation and individualized treatment.
