Abstract

Uroflowmetry is a noninvasive lower urinary tract study that provides objective information of the urine flow, final result of urination. If it is normal bladder outlet obstruction and impaired bladder contractility can reasonably be discarded. Most used parameters in this examination are voided volume, maximum flow rate, average flow rate and flow-curve pattern. Normal values depend on patient’s voided volume, sex and age. Different nomograms have been used for their interpretation, within them we highlight Liverpool’s. Finally, the flow-curve pattern can guide to an underlying disease but it isn´t reliable.
