摘要
目的:探讨含三聚氰胺问题奶粉致泌尿系结石的影像学特点。方法:回顾性分析620例有服用问题奶粉喂养史婴幼儿的影像学资料,对其中48例患有泌尿系结石患儿(总计82个部位)的影像学资料进行描述性分析。按检出部位计算,用优势比(OR值)来评价MSCT与B超结石的检出效果。结果:本组48例患儿均行B超,10个部位未检出,检出率88%;28例患儿行肾尿路平片(KUB),结石均未检出,检出率0%;43例行MSCT,结石均检出,检出率100%。B超与MSCT在统计学上部位的检出率没有显著差异。结论:有服用问题奶粉喂养史婴幼儿泌尿系结石大部分为X线阴性结石,筛查首选B超检查,MSCT是诊断该疾病的有效补充,应根据患儿具体情况合理选择影像学检查方法。
Objective：To explore the characteristic imaging features of urinary lithiasis caused by milk powder contaminated with melamine. Methods：The imaging materials of 620 infants who had been fed by milk powder adulterated with melamine were reviewed retrospectively. Of whom, 48 infant patients with urinary lithiasis with total of 82 sites were descriptively analyzed. Based on the sites with urinary calculus, the odds ratio were used to evaluate the effectiveness of MSCT and ultrasonography. Results：48 infant patients were examined by ultrasonography, 10 sites of urinary calculus were not detected, the detection rate of ultrasonography was 88%. For 28 infant patients had KUB X-ray plain film,no calculus was detected. The detection rate of calculus by MSCT was 100%. No significant statistical difference was existed between MSCT and ultrasonography. Conclusion：Most of the urinary lithiasis of infants fed by milk powder adulterated with melamine did not absorb X-ray,and were ＂negative stone＂, ultrasonography should be the first choice technique for calculus screening, MSCT is an effective complementary technique for diagnosis.
