The diagnostic value of ultrasound kidney biometry in the diagnosis of parenchymatous kidney disease was evaluated in 277 children. Kidney enlargement of more than 140% of normal volume proved to be a sensitive criterion for differentiation of acute bacterial interstitial nephritis (pyelonephritis) and isolated lower urinary tract infection. Mean kidney volume in acute pyelonephritis was 175%. Normalization of kidney volume under antibiotic treatment required 4-6 days. Kidneys with non-bacterial nephritis and glomerulonephritis showed a 63% pathological size increase at biopsy; the kinetics of kidney volume in the acute phase of the disease paralleled the clinical course.
