摘　　要：目的:探讨多层螺旋CT(multislice spiral CT,MSCT)曲面重建(curved pla-nar reconstruction,CPR)在诊断泌尿系结核中的价值。材料和方法:收集经病理检查证实的23例泌尿系结核,分析其征像,比较三维后处理技术的结果,并评估其在诊断泌尿系结核中的应用价值。结果:双肾、输尿管同时受累9例,其中4例同时累及膀胱;单侧肾及输尿管受累13例,同时累及膀胱1例;仅发生于单侧输尿管下段1例。MSCT表现为患肾实质内多个大小不一的囊样低密度影,边缘模糊,增强扫描边缘轻度增强,排泄期见造影剂充填,输尿管管壁不均匀增厚、管腔变窄,其间见扩张的输尿管,增强明显,呈串珠状改变,肾功能不同程度受损;膀胱受累表现为膀胱腔明显缩小,壁增厚,增强明显;大范围的曲面重建可全程清晰显示病变累及范围,直观显示输尿管腔内外改变,与术中及病理符合。结论:MSCT能清晰地显示病变部位、累及范围、腔内外改变以及肾功能情况,是诊断泌尿系结核的一种很好的影像方法,CPR对病变的显示及诊断非常实用。Purpose To evaluate curved planar reconstruction（CPR） of multislice spiral CT（MSCT） in diagnosis of urinary tract tuberculosis.Materials and Methods 23 cases MSCT findings of urinary tract tuberculosis were analysed that were confirmed by pathology in our hospital and the different three dimension postprocessing technologies were compared retrospectively.Results Bilateral kidneys and ureters were involved in 9 cases,bladder was also involved in 4 of 9.Unilateral kidney and ureter were involved in 13,bladder was also involved in 1 of 13.,and only unilateral lower ureter was involved 1 case.MSCT showed multiple peripheral low-grade enhancing cystic masses in renal parenchyma,which the contrast material was filled in them in excretory-phase.MSCT showed the asymmetrical,thickened and enhanced,ureteral wall,and irregular stricture and dilated lumen which appeared as a ＂bead＂.The renal function was impaired.The involved bladder was shrank,thicked and enhanced wall.CPR could clearly displayed the pathological localization ,extent,and changes inside and outside the lumen and cavity,acorded with operation and pathology.Conclusions MSCT is a good radiological technology to display the pathological localization,extent,the changes inside and outside the lumen and cavity and the renal function.CPR plays an important role to display pathological changes and diagnosis.
