Home > Health Library > Enlarged Prostate: Uroflowmetry Test
The uroflowmetry test measures the rate of urine flow during urination. Results are usually given in milliliters per second (mL/sec). This test is sometimes used to evaluate the impact benign prostatic hyperplasia (BPH) has on urine flow or to monitor the effect of treatment. Your doctor and studies about treatment for BPH may talk about this test as "peak urine flow rate." Many treatments for BPH can increase the peak urine flow rate for men.
A urine flow rate that is normal or nearly normal in a man with BPH may indicate that the bladder has become stronger to compensate for the partially blocked 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.
