目的探讨螺旋CT技术诊断输尿管外科疾病的应用价值。方法选择各种典型患者25例,其中输尿管狭窄4例、输尿管重复畸形2例、输尿管肿瘤8例及输尿管结石11例,比较螺旋CT与静脉尿路造影(IVU)、B超等诊断技术诊断各种输尿管疾病的优缺点。结果螺旋CT可获得不同层面、不同角度的三维或二维图像,能提供更为直观、全面的影像资料,明确病变的大小、部位及其与周围组织的关系。结论螺旋CT能进行快速薄层扫描,重建图像质量好,与IVU、B超相比较对输尿管疾病的诊断和治疗方案的设计更具有指导价值,可作为临床诊断的一种有效的辅助检查手段。
Objective To explore the value of spiral CT in the diagnosis of ureteral diseases. Methods Twenty-five patients with typical ureteric stenosis were selected, including 4 cases of ureteral stricture, 2 cases of ureteral recurrence, 8 cases of ureteral tumor and 11 cases of ureteral calculi. The diagnostic results of spiral CT, IVU and B ultrasound The advantages and disadvantages of ureteral diseases. Results Spiral CT can obtain three-dimensional or two-dimensional images at different levels and angles, which can provide more intuitive and comprehensive image information and clarify the size and location of lesions and their relationship with the surrounding tissues. Conclusion Spiral CT can be used for rapid thin-section scanning and reconstruction of images with good quality. Compared with IVU and B-ultrasound, spiral CT can guide the design of diagnosis and treatment of ureteral diseases, and can be used as an effective auxiliary examination method in clinical diagnosis.
