摘要
目的:探讨泌尿系统水成像(MRU)技术对小儿先天性肾积水的临床应用价值。方法:回顾性分析52例手术证实为先天性肾积水的小儿MR图像。所有患儿均行冠状位MRU及兴趣区轴位T2WI序列检查。结果:52例患儿中,肾盂输尿管连接部狭窄35例,原发性巨输尿管4例,重复肾盂输尿管畸形7例,输尿管末端囊肿2例,肾发育不全或异位肾4例。手术中所见与MRU图像表现基本一致。结论:MRU能够无放射线、无需对比剂、多角度、直观显示小儿肾脏积水和/或合并其它泌尿系畸形。
Objective：To evaluate the clinical application of congenital hydronephrosis in infants with magnetic resonance urography.Methods：52 cases of MRI appearances of congenital hydronephrosis in infants were retrospectively analyzed.MRU（coronal） and MRI（axies） examinations were performed in all cases.Results：In all cases,obstruction was located at conjunction of renal pelvis and ureter in 35 cases,congenital megaureter in 3 cases,double renal pelvis and ureter in 7 cases,ureterocele in 13 cases,renal dysplasia or agenesis in 4 cases.MRU findings were found to be consistent with surgical findings.Conclusion：With the advantages of no X-ray ionizing radiation,no contrast medium,and multi-angle observation and visual display,MRU is one of best methods for detecting the pathogen of congenital hydronephrosis in infants.
