目的:探讨CT尿路造影(CTU)对泌尿系结核的诊断价值。方法:回顾性分析进行CTU或IVP检查并经临床确诊的泌尿系结核患者的影像资料,与病理结果对照。结果:79例纳入研究。50例CTU检查提示诊断46例。29例IVP检查提示诊断13例。CTU诊断率高于IVP。泌尿系结核的CTU征象主要有:肾实质内多发或单发类圆形低密度灶、肾内点片状钙化灶、肾盏不均匀扩张、尿路上皮增厚、输尿管僵直、“串珠样”改变及膀胱挛缩等。结论:CTU能准确反映泌尿系结核的不同病理改变,可作为一线检查手段,特别是对于肾功能差和IVP显影不良的患者能提供更多的诊断信息。
Objective: To investigate the diagnostic value of CT urography in urinary tuberculosis. Methods: The imaging data of urinary tuberculosis patients who underwent CTU or IVP examination and clinically diagnosed were retrospectively analyzed, which were compared with the pathological results. Results: 79 cases were included in the study. 50 cases of CTU examination prompted the diagnosis of 46 cases. 29 cases of IVP examination prompted the diagnosis of 13 cases. The diagnostic rate of CTU is higher than that of IVP. CTU signs of urinary tuberculosis are mainly: multiple or single within the renal parenchyma round low-density lesions, intraluminal punctate calcification, uneven expansion of the calyx, urinary tract epithelial thickening, ureteral rigidity, “beaded ”Change and bladder contracture. Conclusion: CTU can accurately reflect the different pathological changes of urinary tuberculosis, can be used as a first-line examination, especially for patients with poor renal function and IVP dysplasia can provide more diagnostic information.
