[Diagnostic value of determination of urinary enzymes].

Criteria to be followed, according to the AA., when choosing urinary enzymes to be determined for the evaluation of the anatomical and fuctional situation of kidney, are discussed. These criteria are essentially based on the localization of these enzymes in the organism and on their molecular dimensions. The behaviour of some enzymes, more or less strictly adhering to these criteria, is considered, in relation to glomerular or tubular disfunctions or to parenchimatous lesions. The present and future possibilities of this kind of approach for the analysis of renal alterations are evaluated.
