[Renal sonography in childhood. Normal findings].
In a prospective study 201 children with healthy kidneys were sonographically examined. Apart from the length unspecific parameters in the ultrasound tomogram, such as possibility to delimit the organ, echogenity and differentiation of the fine structure of the kidneys are demonstrated depending on age. The proportion of smoothly delimited kidneys before the 1st year of age was significantly lower than in the following years. With growing age the possibility to delimit mean echocomplex, renal medulla and renal cortex. In the 1st and 2nd trimenon the echo-richness of the kidneys is to be valuated physiologically. The demonstrated dynamics of sonographic signs shall alleviate the age-specific judgement of renal diseases without disturbance of the urine transport.
