摘要
目的:探讨经尿道输尿管镜碎石术(URL)治疗输尿管结石术后早期并发症的危险因素。方法:回顾合肥市第八人民医院2018.01~2021.12间行URL治疗输尿管结石出现并发症的85例患者和200例未出现并发症的患者,采取倾向性评分匹配方法进行分析。对于阳性的单因素,进行二元Logistic回归分析,并建立预测模型并绘制ROC曲线。结果:输尿管上段结石、合并输尿管狭窄、结石CT值、结石长径>2cm以及手术时间≥60min是URL术后早期并发症的独立危险因素。预测模型显示ROC曲线下面积为0.942(0.909~0.975),敏感度为88.9%,特异度为86.4%。结论:预测模型具有较好的诊断效能,对URL术后早期并发症的发生有着较好的预测效果。
Objective:To explore the potential risk factors associated with early complications following transurethral ureteroscopic lithotripsy(URL)for ureteral calculi.Methods:A review of 85 patients who developed complications from URL treatment of ureteral stones performed betweenFrom January 2018 and December 2021 at the Eighth People's Hospital of Hefei and 200 patients who did not develop complications were analyzed by propensity score matching method.For the positive single factor,a binary logistic regression analysis was performed,and a prediction model was developed and ROC curves were plotted.Results:Upper ureteral stone location,concurrent ureteral stenosis,high CT attenuation value of the stone,stone length exceeding 2 cm,and operation time of 60 minutes or longer were identified as independent risk factors for early complications following transurethral ureteroscopic lithotripsy(URL).The predictive model achieved an area under the receiver operating characteristic curve of 0.942(95%confidence interval:0.909-0.975),demonstrating a sensitivity of 88.9%and specificity of 86.4%.Conclusion:The prediction model has good diagnostic efficacy and is a good predictor of early complications after URL surgery.
