摘要
目的 探讨多层螺旋CT尿路成像（multislice spiral CT urography,MSCTU）对上尿路先天性畸形的诊断价值.方法 收集本院2011年5月-2013年12月44例上尿路畸形的病例,男23例,女21例,年龄16～ 87岁,回顾性分析44例经手术病理或临床证实的上尿路先天性畸形患者的CTU资料,44例均行128层螺旋CT平扫加多时相分期增强扫描,对获取的图像数据进行二维多平面重建、曲面重建、最大密度投影、三维容积再现后处理.结果 44例中,肾融合畸形8例,肾位置异常2例,输尿管狭窄13例,重复肾输尿管畸形11例,输尿管囊肿5例（其中1例内合并结石及同侧重复输尿管畸形）,巨输尿管2例,肾发育不良1例,输尿管闭锁1例,输尿管瓣膜1例.结论 128层螺旋CTU能清晰显示上尿路先天性畸形的类型及其并发症,为临床提供科学、可靠的影像信息.
Objective To study the value of 128-layer spiral CT in diagnosis of upper urinary tract congenital malformation. Methods Clinical data about 44 patients （23 males and 21 females with the ages ranging from 16 to 87） with upper urinary trait congenital malformation admitted to our hospital from May 2011 to December 2013 wre retrospectively analyzed. The patients underwent 128- layer spiral CT scanning. Their imaging data were processed by 2-dimensional multiple-plane reconstruction, camber reconstruction, maximal density projection, and 3-dimensional volume representation, respectively. Results Of the 44 patients, 8 were diagnosed with renal fusion malformation, 2 with anomaly of kidney, 13 with stricture of ureter, 11 with repetitive nephroureter malformation, 5 with ureter cyst （including 1 with complications of stone and homolateral repetitive ureter deformity）, 2 with giant ureter, 1 with renal dysplasia, 1 with ureter atresia, and 1 with ureter valve. Conclusion 128- layer spiral CT can clearly display upper urinary tract congenital malformation and its complications, thus providing scientific and reliable image information for its clinical diagnosis.
