uroflowmetry

(ū″rō-flō′mĕ-trē) Timed measurement of the rate of urination. Uroflowmetry is used to diagnose conditions that result in slow urinary output, e.g., bladder outlet obstruction resulting from enlargement of the prostate gland. The maximal volume of urinary flow over time is called the Qmax. A Qmax of less than 10 ml of urine/second is an indication of significantly reduced urinary output.
