[Uroflowmetry and its methodology for establishment of urinary flow parameters. I].

In the present paper the author deals in a short form with the importance of the uroflowmetry as a functional examination method. Prerequisite for every documentation of the picture of the miction curve is the diagram of the urinary flow. Here only the direct curve of the flow is suited for the immediate readability of the adequate values as well as for the simultaneous recognition. For the superficial orientation about the course of the flow the control of the curve is enough, but for the differentiated evaluation the following factors must be taken into consideration: Time of flow, time of waiting, different and maximum urinary flow, increase of the curve of the urinary flow and number of the peaks of flow. Also the differentiating uroflowmetry should be taken into consideration, in order to separate neurogenic disturbances of the urinary bladder from obstructive changes of the vesical outlet in the screening method.
