【摘要】：目的:探讨数字断层融合技术与多种影像学方法在诊断输尿管结石中的影响因素并对比分析各种影响因素。方法:回顾性分析并收集2015年10月至2016月6月同时行超声、腹部平片、静脉肾盂造影及数字断层融合技术检查并经临床或CT证实输尿管结石的患者,共253例。由三个高年资医师获取与影响检出输尿管结石相关性高的因素,再使用Logistic回归分析对其危险度进行分析。结果:共提取17个影响因素,临床症状7个,影像学特征10个,经分析其中5个差异有统计学意义,分别为结石形态,位置,大小,密度;骨质增生,恶心呕吐,酸胀不适;其中危险因素(有利检出):US为大小;KUB为形态、大小、位置及密度;DTS为形态及密度;IVP为形态、位置、大小及密度;IVP+DTS为位置及密度。结论:DTS联合IVP可降低结石形态、位置、密度及大小的影响,消除重叠、阴性结石及骨性结构的遮挡,提高输尿管结石检出率。
[Abstract]:Objective: to investigate the influencing factors of digital tomography fusion technique and various imaging methods in the diagnosis of ureteral calculi. Methods: from Oct. 2015 to June 2016,253 patients with ureteral calculi confirmed by clinical or CT examination were retrospectively analyzed and examined by ultrasound, abdominal plain film, intravenous pyelography and digital tomography fusion technique. The risk of ureteral calculi was analyzed by Logistic regression analysis. Results: 17 influencing factors were extracted, including 7 clinical symptoms and 10 imaging features. Five of them were statistically significant, including the shape, location, size and density of stones, hyperosteogeny, nausea and vomiting, acid swelling and discomfort. Among them, risk factors (favorable to detect the size of): US; KUB as morphology, size, location and density; DTS as morphology and density; IVP as shape, position, size and density; IVP DTS as location and density). Conclusion: DTS combined with IVP can reduce the influence of shape, location, density and size of calculi, eliminate overlapping, negative stones and occlusion of bone structure, and improve the detection rate of ureteral calculi.
