[Evaluation of diagnostic parameters in chronic recurrent urinary tract infections in children. IV. The isotopic renogram (author's transl)].
The results of isotopic renograms (ING) (n = 73) and renal concentration capacity tests (n = 65) performed at the same time before and during therapy of recurrences have been compared. In 43 children with chronic urinary tract infections. ING done prior to chemotherapy showed pathologic findings in 65% of children with bacteriuria. A significant correlation between normal and pathologic findings of ING and renal concentration capacity tests has been found. Impaired (normal) renal concentration capacity lead to pathologic (normal) ING in 74% of cases. 94% of children with a pathologic ING either had bacteriuria children with pyelonephritis (n = 19) the ING was pathologic, whereas in all children with cystitis (n = 8) it was normal. During therapy the ING became normal before the impaired renal concentration capacity returned to normal.
