title: Ultrasonographic assessment of kidney dimensions in first six months of life.
abstract: The kidney growth in children is not linear. The aim of this study was to define normal dimensions of kidneys in healthy infants during the first six months of life. A prospective ultrasonographic screening of 1870 kidneys in 935 healthy full-termed infants (476 males, 459 females) was done throughout a 5-year period. Measured kidneys were divided into six age groups according to gender and side. In the first three months of life males had both kidneys longer than same-age females (p < 0.05). In the next three-month-period the difference between sexes was not significant (p > 0.05). Left kidneys were longer than right kidneys in both sexes in the first six months of life (p < 0.01). Four nomograms with normal values of kidney lengths, according to age, sex and side were done in newborns and infants in the first 6-months of life.
