A prospective study was conducted in children with urinary tract infections to examine the relationship between the presence of antibody-coated bacteria in the urinary sediments and the presence of pyelonephritis. The site of the urinary tract infection was localized as upper or lower urinary tract by the bladder washout technique. Antibody-coated bacteria in the urinary sediments were identified by an immunofluorescent method. In 4 of 12 children with upper urinary tract infections, less than 1% of the bacteria in the urinary sediments were antibody coated. In 10 of 35 children with lower urinary tract infections more than 50% of the bacteria in the urinary sediments were antibody coated. These studies show no significant correlation between the presence of antibody-coated bacteria in urinary sediments and infection of the upper urinary tract.
对患有尿路感染的儿童进行了一项前瞻性研究，以检查尿沉渣中抗体包被细菌的存在与肾盂肾炎的存在之间的关系。通过膀胱冲洗技术将尿路感染的部位定位为上尿路或下尿路。采用免疫荧光法鉴定尿沉渣中的抗体包被细菌。在12例上尿路感染患儿中，有4例尿沉渣中不到1%的细菌被抗体包被。在35例下尿路感染患儿中，有10例尿沉渣中超过50%的细菌被抗体包被。这些研究表明，尿沉渣中抗体包被细菌的存在与上尿路感染之间没有显著相关性。
