目的探讨静脉肾盂造影(IVP)在小儿先天性输尿管狭窄诊断中的价值。方法回顾性分析47例IVP诊断为先天性输尿管狭窄患儿的影像学表现,并与术后结果进行比较。结果手术证实IVP诊断与手术结果一致,具体为:43例患儿肾盂输尿管连接处狭窄;4例输尿管下端狭窄。结论 IVP诊断小儿先天性输尿管狭窄准确率高达100%(47/47),但患儿在造影过程中接触射线较多,所以造影医生应选择最佳的造影操作技巧,以使患儿接触射线量降至最低。
Objective To investigate the value of intravenous pyelography (IVP) in the diagnosis of congenital ureteral stricture in children. Methods The imaging findings of 47 cases of IVF diagnosed as congenital ureteral stricture were retrospectively analyzed and compared with the postoperative results. Results The operation confirmed IVP diagnosis consistent with the surgical results, specifically: 43 cases of ureteropelvic junction stenosis; 4 cases of ureteral stenosis. Conclusion IVP diagnosis of children with congenital ureteral stricture accuracy rate as high as 100% (47/47), but in children with angiography in contact with more radiation, angiography doctor should choose the best imaging techniques to make the amount of exposure to radiation Minimize.
