A study of bacteriuria was conducted among 426 of the 436 children under the age of 13 in a general practice in north-west London. Three girls and one boy were found to have asymptomatic bacteriuria, and a further girl with bacteriuria presented with abdominal pain and fever. The calculated incidence of urinary tract infection was 1.4% per annum. Most of the childhood urinary infections in this practice occurred before the age of 5 years, and the incidence of significant bacteriuria in this age group was 4.9% per annum. Five other children (four girls and one boy) in the practice were known to have had proved urinary tract infection. Of the total of eight children known to have had significant bacteriuria and investigated radiologically, three girls and two boys had radiological abnormalities in the urinary tract.Pyuria and proteinuria did not prove to be useful in the prediction of asymptomatic bacteriuria. Urinary tract infection with renal tract abnormality was found in this practice to be at least five times as common as diabetes in childhood.
在伦敦西北部一家普通诊所里，对436名13岁以下儿童中的426名进行了一项关于菌尿症的研究。发现三名女孩和一名男孩有无症状菌尿症，另有一名患有菌尿症的女孩出现腹痛和发热症状。计算得出的尿路感染年发病率为1.4%。该诊所中大多数儿童期尿路感染发生在5岁之前，这个年龄组中显著菌尿症的发病率为每年4.9%。该诊所还有另外五名儿童（四名女孩和一名男孩）被证实曾患尿路感染。在已知患有显著菌尿症并接受放射学检查的八名儿童中，三名女孩和两名男孩的尿路存在放射学异常。脓尿和蛋白尿在预测无症状菌尿症方面并无用处。在该诊所发现，伴有尿路异常的尿路感染在儿童期至少是糖尿病的五倍。
