An attempt to characterize certain parameters of the radiorenographic curve in children with intact kidneys and urine passages.
The authors evaluated 48 curves for the right and left kidney of 24 children free from any disorder of the uropoietic system, in whom radiorenography formed part of a general examination. In the recordings they evaluated the "secretory" (ta) and "excretory" (td) parts of the curves and percentual differences in the recordings for times ta and td and at 5, 10 and 15 minutes. The percentual differences in the curves were compared with the findings in a group of 64 children with cystopyelonephritis. Times ta and td for the whole group of investigated children were normal. Percentual differences between the curves for the right and left kidney were significantly smaller in the "healthy" group than in the children with cystopyelonephritis. Comparison of the results in the two groups showed that the differences were statiscally significant or highly significant. The drop in the recordings at 5, 10 and 15 minutes corresponded to the normal findings in adults.
