[The excretion of N-acetyl-beta-D-glucosaminidase in the urine of children with urinary tract diseases].
In 81 children without any urinary or kidney disease and in children with various diseases of the urinary tract, the excretion of N-acetyl-beta-D-glucosaminidase (NAG) was measured in an urine sample and related to creatinine excretion. The values of the first group of children accorded well with normal values reported in the literature. The age dependency (1-12 years) of the ratio NAG/creatinine is not of great importance, a single normal value for mean and mean + 2SD can be used. The estimation of NAG proved to be a relatively simple and useful measure of the involvement of the upper urinary tract in urinary infections. This is important for decisions about choice of treatment and further urological investigations.
