摘　　要：目的:评价MSCT三期扫描在妇科腹腔镜致输尿管下段损伤中的诊断价值。方法:回顾性分析经手术证实的12例妇科腹腔镜致输尿管下段损伤的术前MSCT表现。结果:12例中,双侧输尿管损伤2例,左侧输尿管损伤6例,右侧输尿管损伤4例,5例CT平扫显示输尿管中段不同程度扩张、7例未见异常,5例盆腔积液;增强扫描输尿管壁强化期:6例输尿管壁模糊,5例输尿管壁轮廓不连续,7例输尿管近膀胱处显示不清;输尿管对比剂充盈期:5例显示输尿管中段不同程度扩张,9例充盈早期患侧输尿管较健侧显示迟缓,12例输尿管下段近膀胱处中断、显示浅淡、密度不均、轮廓不规整呈鼠咬状改变,7例输尿管周围软组织密度影或团片状高密度影;延迟期:5例盆腔积液呈高密度,于阴道区域显示高密度影1例,10例显示输尿管全程。9例行图像后处理,5例显示输尿管管腔中段扩张,9例均显示下段多发不规则狭窄、缺损或中断。结论:MSCT三期扫描对妇科腹腔镜致输尿管下段损伤能够准确诊断,其中输尿管下段增强后"日冕征",显示浅淡、密度不均、多发轮廓不规整呈鼠咬状改变及连续性中断为特征性征象。Objective:To evaluate multidetector spiral CT(MSCT) tri-phase scanning in the diagnosis of distal ureteral injury caused by gynecological laparoscopic operation.Methods:The pre-/post-operation MSCT appearances of 12 cases which had surgery proved distal ureteral injury caused by gynecological laparoscopic operation were retrospectively analyzed.Results:Of all the 12 cases,there were bilateral ureteral injuries(2 cases),left(6 cases) and right ureteral injury(4 cases).5 cases had middle and distal ureter dil...
