摘要/Abstract

摘要： 本研究探讨术前CT检查参数预测输尿管结石患者发生输尿管嵌顿的临床价值。选取嵌顿性输尿管结石的患者68例为嵌顿组、98例未发生输尿管嵌顿的患者为对照组,两组患者术前均接受CT扫描。结果发现,结石长径诊断患者发生输尿管结石嵌顿的灵敏度为83.15%、特异度为70.69%、AUC值为0.836;结石体积诊断患者发生输尿管结石嵌顿的灵敏度为78.85%、特异度为61.33%、AUC值为0.745;Logistic回归模型结果显示:同侧结石手术治疗史、输尿管壁厚度增加、结石长径越长、结石体积越大,患者发生输尿管结石嵌顿的风险越高(P<0.05)。CT检查结石的负荷参数对于诊断患者发生结石嵌顿具有一定的价值,结石长径增大、输尿管壁增厚等因素会加大患者发生结石嵌顿的风险。

Abstract: This study explored the clinical value of preoperative CT examination parameters to predict ureteral chimerism in patients with ureteral stones. Sixty-eight patients with ureteral incarcerated stones were selected as the incarcerated group, and ninety-eight patients without ureteral incarcerated were selected as the control group. Both groups received CT scan befor operation. The sensitivity, specificity and AUC of stone length in the diagnosis of ureteral calculi incarceration were 83.15%, 70.69% and 0.836, respectively. The sensitivity, specificity and AUC of ureteral calculi incarceration were 78.85%, 61.33% and 0.745, respectively. The results of logistic regression model showed that the risk of ureteral calculi incarceration in patients with ipsilateral calculi surgery history, increased ureteral wall thickness, longer calculi length and larger calculi volume was higher (P<0.05). The load parameters of CT examination of stones have a certain value for the diagnosis of patients with stone incarceration. The increase in the length and diameter of stones and the thickening of the ureteral wall will increase the risk of stone incarceration in patients.
