摘　　要：目的:提高外伤性肾盂输尿管交界处断裂的CT诊断水平。方法:回顾性分析5例经手术证实的外伤性肾盂输尿管交界处断裂的CT表现。结果:CT平扫无特异性表现,主要有肾周积液、血肿形成及肾盂积水,伴有肾挫裂伤时可有包膜下低密度影;增强后分泌期扫描表现为肾周高密度影积聚、输尿管显示不连续,尤其是三维重建能直观显示肾盂输尿管交界处断裂征象。结论:CT对外伤性肾盂输尿管交界处断裂有重要诊断价植,尤其是增强后分泌期扫描及三维重建。Objective： To improve the diagnosis of traumatic disruption pelvis - ureter junction. Methods： The CT findings in 5 cases of traumatic disruption pelvis - ureter junction confirmed by surgery were analyzed retrospectively. Results： Plain scan of CT has non- specific findings, including peri - renal fluid collection, haematoma, nephrydrosis and low density when complicated with kidney laceration; excrete phase after enhancement showed high density shadow accumulation in peri - kidney area and disontinuation of ureter. 3 - dimension reconstruction showed disrupting sign at the junction between pelvis and ureter. Conclusion： CT, especially excrete phase scan after enhancement and 3 - dimension reconstruction, has high value in the diagnosis of disruption pelvis - ureter junction.
