title: Possibilities of computing urine parameters as a means of classification of normals and patients suffering from calcium oxalate lithiasis.
abstract: By the use of simple quotients consisting of the lithogenic variables in the numerator and the litholytic ones in the denominator as well as of complex chemical and discriminant analytical computational use of urine parameters, it is possible to distinguish significantly between groups of control persons and recurrent calcium oxalate stone formers and to obtain a relative prediction concerning the risk of stone formation. In discriminant analytical computation, in our opinion, it is most convincing to make use of variables which have been checked multivariately concerning their separating properties with regard to their mutual correlations and their measure of indispensability.
