Uroflow rate is a useful screening test used mainly to evaluate bladder outlet obstruction, but will also identify detrusor weakness. Uroflow rate is volume of urine voided per unit of time.

Low uroflow rate may reflect urethral obstruction, a weak detrusor, or a combination of both. This test alone cannot distinguish an obstruction from a contractile detrusor.
