摘要
目的：探讨三聚氰胺相关婴幼儿泌尿系结石的临床及超声特点。方法：回顾性分析我院2008年9～10月高频超声筛查确诊的267例因食用三聚氰胺污染奶粉致婴幼儿泌尿系结石的流行病学特点以及超声声像图特征。结果：1～2岁年龄组婴幼儿结石检出率最高（48％），男性多于女性（1．5：1），结石单发（44％）与多发（45％）百分比相近。单发结石发生于肾下盏者最多（57％）；结石呈碎渣样堆积，结构松散，伴淡声影，后缘清晰可见；食用奶粉时间1-2年组与〈1年组比较结石大小无显著性差异（P〉0．05），〉2年组结石大小与以上两组比较具有显著性差异（P〈0．05）。结论：三聚氰胺污染奶粉致婴幼儿泌尿系结石在临床分布及超声表现等方面有其独特的特点。
Objective： To evaluate the characteristic of clinical symptoms and ultrasound in infants with Melamine related urinary calculus. Methods： Data of 267 infant patients with urinary calculus due to drinking of Melamine tainted formula milk admitted to the Second Hospital of Lanzhou University from Sept. 2008 to Oct. 2008 were analyzed retrospectively, including clinical and ultrasound characteristics. Results： The infants aged 1-2 years showed highest incidence of urinary calculus. The ratio between male and female in infants was 1.5：1. The percentage of stones located in lower renal ealices was the highest （57%）. Various forms of stones based on the accumulated appearance were as broken slag, posterior border of stone was clear, and accompanied with acoustic shadow. The size of calculus in infants being fed with Melamine tainted formula milk between less than one year and one to two years had no statistically significant difference （P〉0.05）. Compared with the group of less than one year and one to two years, the size of calculus in infants more than two years had statistically significant difference （P〈0.05）. Conclusion： The high-frequency ultrasound provide a simple and an accurate method for characterization and quantitation oof Melamine related urinary calculus in infant.
