Abstract
The uroflowmetry has value as a screening procedure in bladder outlet diseases and in assessing results of treatment. The results of measurement depend on the circumstances of micturition, on the bladder volume and on how far the patient is cooperative. The interpretation of measurements must be related not only to maximum flow and micturition time, but also to a specific micturition pattern. As an isolated method the uroflowmetry has limitations. The value of this procedure may increase by pressure measurements during micturition. Caution should be exercised in interpreting a resistance factor. Extensive information is presented by simultaneous cine-pressure-flow measurement. Additional urodynamic procedures, especially the urethra pressure profile, are of no value in bladder outlet obstructions.
