title: [Bladder outlet obstructions: the value of urodynamics (author's transl)].
abstract: The uroflowmetry has value (1) as a screening procedure in bladder outlet diseases, and (2) in assessing results of treatment. The results of measurement depend: (1) on the circumstances of micturition; (2) on the bladder volume, and (3) 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. However, 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.
