摘要
[目的]探讨输尿管壁面积在嵌顿性输尿管结石诊断中的预测价值.[方法]收集延边大学附属医院泌尿外科收治的110例输尿管结石患者的临床资料,根据是否为嵌顿性输尿管结石分为嵌顿组(54例)和非嵌顿组(56例),行单因素分析后初步得出有统计学意义的变量纳入多因素Logistic回归分析,并对独立危险因素进行相关性分析,绘制受试者工作特征(ROC)曲线,得出预测结石嵌顿的独立危险因素及截点值.[结果]两组UWAmax、UWTmax、结石最大横径、结石CT值、结石近端输尿管壁CT值及结石远端输尿管壁CT值间差异均具有统计学意义(P＜0.05).UWAmax、UWTmax及肾盂直径是嵌顿性输尿管结石的独立危险因素(P＜0.05).UWAmax截点值为64.050 mm2,UWTmax为3.150 mm,肾盂直径为43.250 mm.[结论]UWAmax及UWTmax均可作为嵌顿性输尿管结石诊断的术前预测指标;当UWAmax＞64.05 mm2或UWTmax＞3.15 mm时发生嵌顿性输尿管结石的可能性较大.
Abstract
OBJECTVE To explore the predictive value of ureteral wall area in the diagnosis of impacted ureteral calculi.METHODS The clinical data of 110 patients with ureteral calculi admitted to Urology Department,Affiliated Hospital of Yanbian University were collected.According to whether it was impacted ureteral calculi,they were divided into incarcerated group(54 cases)and non-incarcerated group(56 cases).After single factor analysis,the variables with statistical differences were included in the multivariate Logistic regression analysis,and the correlation analysis of independent risk factors was performed.Receiver-operating characteristic(ROC)curve was drew to conclude the predict independent risk factors for calculus incarcerated and cut-off value.RESULTS There were statistically significant differences in UWAmax,UWTmax,maximum transverse diameter of the stone,CT value of the stone,CT value of the proximal ureteral wall and CT value of the distal ureteral wall between the two groups(P＜0.05).UWAmax,UWTmax and diameter of the renal pelvis were independent risk factors for impacted ureteral calculi(P＜0.05).The cut-off values of UWAmax and UWTmax were 64.050 mm2 and 3.150 mm,respectively,renal pelvis diameter was 43.250 mm.CONCLUSIONS UWAmax and UWTmax can be the preoperative predictors of diagnosis for embedded ureteral calculi.When UWAmax＞64.05 mm2 or UWTmax＞3.15 mm,impacted ureteral calculi are more likely to occur.
