Summary
Introduction:
Potential complications of acute pyelonephritis include irreversible changes on the kidneys – renal scars, which may result in secondary hypertension and subsequently to chronic kidney failure. In addition to physical examination of the patient, blood and urinary analysis, ultrasonography of the kidneys contributes to diagnosis.
Objectives:
The authors attempted to verify the possibility to use measurement of the resistance index (RI) during acute phase of pyelonephritis for confirmation of the diagnosis.
Cohort and methods:
53 children were eligible in the group (43 girls, 10 boys) at the age of 0–19 years at the first attack of acute pyelonephritis. The patients were divided into three age groups – children up to 4 years, 4 to 7 years and children older than 7 years and they were compared with a group of 29 children without symptoms of acute infection and normal kidney function. Ultrasonography examination of uropoietic tract oriented to kidney morphology was performed in all patients up to 72 hours from the beginning of hospitalization and RI was measured by beans of Doppler sonography.
Results:
In all the three age categories the authors detected significantly higher values of RO in kidneys affected by inflammation as compared with kidneys of the control group. In the group of children up to 4 years the RI values are 0.67±0.05 against RI 0.63±0.03 of the healthy individuals, in the group of children from 4 to 7 years the RI values were 0.70 (0.69; 0.75) as compared with RI of the healthy group 0.63 (0.61; 0.65) and in the group of children older than 7 years the values were 0.67±0.04 against 0.60±0.03.
Conslusion:
The possibility to use of the resistance index (RI) during acute phase of pyelonephritis contributes to diagnosis.
Key words:
resistance index, Doppler sonography, acute pyelonephritis, kidney disease
