Uroflowmetry Test

Overview

The uroflowmetry test measures how much and how fast (maximum flow rate) urine flows during urination. Results are usually given in milliliters per second (mL/sec). This test is sometimes used to evaluate the impact that benign prostatic hyperplasia (BPH) has on urine flow or to monitor the effect of treatment. Many treatments for BPH can increase the maximum flow rate.

A urine flow rate that is normal or nearly normal in someone with BPH may mean that the prostate is enlarged but is not blocking the urine flow.

A uroflowmetry test is called a pressure flow study when used with a pressure-recording catheter in the bladder. Pressure studies may help distinguish between urinary symptoms caused by blockage and those caused by a problem affecting the bladder muscles or nerves.
