摘　　要：目的 :探讨MRU在儿童先天性泌尿道畸形中的应用价值。方法 :回顾性分析 2 0例儿童先天性泌尿道畸形患者 ,采用快速自旋回波 (TSE)行MRU检查 ,并与IVP和手术结果对照。结果 :肾盂输尿管交界处狭窄 9例 ,输尿管下端狭窄伴巨输尿管 7例 ,输尿管下端盲端、输尿管囊肿、神经性膀胱、后尿道瓣膜伴双侧输尿管返流各 1例。MRU的原始图像及MIP图像清晰地显示梗阻的部位及程度 ,结合常规MRI ,诊断符合率达 90 %。结论 :MRU这一无创性水成像技术 ,能显示无功能性肾脏的集合系统。在儿童先天性泌尿道畸形诊断中有重要作用。Objective:To explore the value of MRU in the congenital urinary tract malformation of children. Methods:20 cases of children with congenital urinary tract malformation were retrospectively analysed.MRU using TSE was performed and the results were compared with that of IVP and operation.Results:The stenosis of the pyelo-uretal junction was in 9 cases,the stenosis of the low end of ureter with megaureter was in 7 cases.Atresia of ureter,ureterocele,neruogenic bladder and posterior urethral valve with bilateral vesicoureteral reflux were in 1 case respectively.The natunal images of MRU and MIP images could show the location and degree of obstruction.The diagnostic rate was 90% combined with routine MRI scans.Conclusion:MRU is a non-invasive technique and plays an important role in the diagnosis of congenital urinary tract malformation of children.
