[Value of the C reactive protein, urinary lactic dehydrogenase and renal capacity of concentration in the topographic diagnosis of the urinary infection in infancy (author's transl)].
In 39 children with urinary infection renal capacity of concentration, serum C-reactive protein and presence of urinary lactic dehydrogenase are studied pointing to the establishment of the topography of the damage. C-reactive protein levels higher than 20 micrograms/ml are 100 per 100 reliable in the diagnosis of pyelonephritis. Moreover, value of this test is confirmed as a guide of therapeutic efficacity. Difficulty of concentrating urine above 800 mOsm/l is 70 per 100 reliable and is a useful method for demonstrating parenchymal damage. The urinary lactic dehydrogenase was superior to 20 units/l in 64 per 100 of the cases, but other studies are necessary for interpretation of these data. These findings are similar to those obtained in the study of the isoenzymes.
