Our predictive formulas allow for direct comparison of one flow to the next in a single patient when the FI is used. Utilizing the FI, we can predict the type of flow pattern removing subjectivity from the analysis of uroflow patterns. Neurourol. Urodynam. 35:836-846, 2016. © 2015 Wiley Periodicals, Inc.

The data support both of our hypothesis that flow index is a good measure of voiding efficiency. We have also shown that IVFE is a better and more accurate measure of calculating a flow index than the power equations regardless of the volume and PVR scenarios that are presented.
