CHARACTERISTIC FEATURES OF THE CLINICAL PICTURE OF CALCULOUS PYELONEPHRITIS IN CHILDHOOD DEPENDING ON AGE GROUPS

Purpose: to determine the characteristic features of the clinicopathology of calculous pyelonephritis among children of different age groups. Methods: in a case-control study, 93 children aged 1 to 14 years with calculous pyelonephritis were included and clinical and laboratory-instrumental investigations were performed. Results obtained: in the age groups of children with calculous pyelonephritis there were significant differences in the frequency of major symptoms: in children aged 1 to 3 years proteinuria (71%), dysuria (67%), leukocytosis (62%) were registered more frequently, while in the groups of children aged 4-7 years and 8-14 years leukocyturia, proteinuria and pain were registered more frequently. The frequency indicated is common in all patients between 1 and 14 years of age. However, there is considerable variation between age groups. So, for the younger age group (1-3 years) the follow-up was as follows: proteinuria, bacteriuria, dysuria, leucocyturia, pain, haematuria. In children of middle age group: leukocyturia, pain, proteinuria, hematuria, bacteriuria, dysuria. In the older age group the signs were distributed in the same sequence as in the whole group, except for changing the places of bacteriuria and dysuria. Conclusions. Our findings indicate that the diagnosis of calculous pyelonephritis should be based on the age-related features of the course of the disease. The main diagnostic sign is the presence of a concrement in the urinary tract. Other main signs (presented in descending order of frequency) are, leucocyturia, pain proteinuria, haematuria, bacteriuria, dysuria.
