The aim is to create a nomogram that relates urinary flow rate to bladder volume for better diagnostics.
Developed a flow rate nomogram based on the relationship between flow rate and bladder volume in normal individuals.
Estimated variability in flow rate for individual subjects over time to assess the impact of medical or surgical therapy.
Achieved excellent differentiation between normal and obstructed urinary flow rates.
Single individual's flow rate variability was found to be relatively small, allowing for reliable tracking of changes in outflow resistance.
Resumen
In normal individuals the flow rate depends on the initial bladder volume in a non-linear fashion. A flow rate nomogram taking this relationship into account was developed as an aid in the interpretation of urinary flow rate data. With this approach excellent differentiation of normal from obstructed individuals was achieved. In addition, the variability in a single individual's flow rate over time was estimated to be relatively small and, thus, uroflowmetry may be used to identify changes in outflow resistance after medical or surgical therapy.
