title: [Uroflowmetry and its methodology. Normal limits. II. Normal range].
abstract: Prerequisite for every evaluation of a uroflowmetry curve are normal regions, on which the diagnostic evidence of the examination method is based. In the present paper a definite attitude to the limits of the normal was adopted, in which case apart from the course of the curve the relations from maximum flow to miction volume were entered. Diagrams of the normal region were established for men, women, and children, in which cases apart from the interindividual diffusion breadth also the individual diffusion breadth was taken into consideration. Error in the diagnostic course develop always then, when only mean values are taken into consideration. The critical consideration of the normal values to age seems to be important, in which cases a peak of the maximum values of the urinary flow is to be established between the 13th and the 40th year. In the later decades of life also without any subvesical obstruction an exponential function similar decrease of the maximum values of the flow develops.
