摘　　要：目的:探讨多层螺旋CT曲面重建(curvedmulti-planarreconstructions,CMPR)在输尿管扩张性疾病的临床应用价值。方法:回顾分析患侧肾功能严重受损的输尿管扩张性疾病33例,手术前均行超声(USG)、静脉尿路造影(IVU)和多层螺旋CT增强检查,多层螺旋CT检查于静脉注射对比剂2～5min后行薄层容积扫描,经独立工作站后处理获得患侧输尿管的CMPR图像。结果:USG发现33例均患侧输尿管积水,但显示梗阻部位及病变不理想;IVU示患侧输尿管未显影;CMPR图像均清楚地显示了输尿管的扩张程度、梗阻部位、病变形态及其与周围组织之间的毗邻关系。结论:多层螺旋CT曲面重建在评价已有患侧肾功能严重受损、IVU检查输尿管未显影的输尿管扩张性疾病上具有重要的诊断价值。Objective： To investigate the clinical value of multi-slice spiral CT with curved multiplanar reconstructions （CMPR） in the expansionary ureteral diseases. Methods： Thirty-three patients with uretal expansion and serious renal failure in the same side were analyzed retrospectively. All the patients underwent USG, IVU and multi-slice spiral CT enhanced scanning before operation. The thin multi-slice spiral CT volume scan was completed 2-5 minutes after enhanced contrast was injected in vein. Images were postprocessed and the CMPR images of the viewed ureters were performed on the independent workstation. Resuits： By USG, the expansionary urinary tracts were detected and the lesions were not clearly displayed; by IVU, the urinary tracts were not filled by contrast; by CMPR, the dilated extent of ureters, the positions and features of the lesions and the relations with adjacent tissues of lesions were clearly displayed. Conclusion： CMPR plays an especially important role in the diseases cannot be displayed by IVU. diagnosis of serious renal failure with expansionary ureteral diseases cannot be displayed by IVU.
