What is Uroflow?

Uroflow vs. Uroflowmeter vs. Uroflowmetry vs. ?

Firstly, yes it is a bit confusing. But, these are all the same. Uroflowmetry is a diagnostic assessment of the urinary tract functionality. Your Urologist or physical therapist suggest performing a uroflow test, in case they suspect that you are suffering while urinating, or have a weak flow rate (stream).

Uroflow, or Uroflowmetry is a test to measure the flow (rate) of micturition. During the test, the uroflow device, a Uroflowmeter, tracks urine flow in mL/sec. It reports Urination volume, meaning, how much urine flows out. It is that simple. Urination Time in seconds, means, How long it takes to urinate.

What is Qmax?

While we measure the total volume of the urination is in mL (milliliter), the flow rate is measured in mL/second, and the Qmax is the value of the highest flow rate measured during the test. In other words, Qmax is the fastest stream measured in mL/s.

Weak flow = Low Qmax

Slow urination speed = Low Qmax

Flat urination chart = Low Qmax

How exactly is a urine flow test performed?

In a clinic, with the conventional method, a nurse will ask you to urinate into a funnel-shaped container placed on a scale-like electronic device. It is important to know that you can not put any toilet paper in the toilet or device.

After your bladder is full, you’ll need to pee normally without manipulating the speed. A conventional electric uroflowmeter hooked up to the toilet record the flow rate and quantity of urination. And of course, never urinate until the machine is on and ready.
