The article presents the results of the research of etiological structure of urinary tract infection among children. Out of the total number of urological and nephrological sick children`s research, it is defined that 283 microorganisms selected from the urine were found. 63.2 % of the total number of children in nephrological department is related to only urological diseases. In recent, there has been an open trend to increase a frequency of diseases of the urinary system. Over the past five years, the number of diseases of the genitourinary system in urban children in Kazakhstan has increased to 65 %.The review shows that inflammatory diseases of kidneys and urinary tract take the second place after acute respiratory diseases of upper breathing tract. In this work, it is established that a causative agent of urinary system infection among children is pathogenic, as well as relative-pathogenic microorganisms. As it is shown, the leading etiological agent of uroinfection is Staphylococcus epidermidis (13.9 %), Escherichia coli (12.2 %), Enterobacter cloacae (7.8 %). In some cases, streptococcus are excreted. Also, there were dominant pathogens of nephroinfection among children such as Escherichia coli (21.1 %), Enterococcus faecalis (9.6 %), Staphylococcus epidermidis (20.1 %). Some types of Candidafungi in the formation of the urinary tract and kidney infection (mostly C.albicans (9.5 %), C.kruseae (8.1 %), C.glabrata (5.6 %) pathogens) are observed in the study of urine in children. During the general research, it was found that the etiological agents of urinary system among children consist of a huge microbiological spectrum, especially among children living in urban areas.
