Uroflowmetry is the most widely used non-invasive, first line screening and relatively inexpensive urodynamic tool for most patients with suspected lower urinary tract dysfunction.Home uroflowmetry can produce multiple representative flow readings in adequate privacy condition when patients feel a normal desire,and combates problems inherent to clinic-based measurements.However, home uroflowmetry is hampered by technical constraints of traditional uroflowmeters.To address these limitations, we design a new portable electronic uroflowmeter, an at-home, wireless system for recording urinary flow data and voiding diaries, and compare accuracy of measurement of the voided volume and flow parameters recorded using this new portable method with those obtained by conventional uroflowmeters.
