What is uroflowmetry?

A uroflowmetry is a non-invasive test that measures the total volume of urine released from the body, the speed at which it is released (millilitres per second) and how long the release takes.

What does it involve?

This test involves passing urine in a machine which looks like a regular toilet. The machine is equipped with a measuring device which can analyse and measure how much urine is being passed during a set amount of time. The machine then generates a report with some graphs.
 

What is uroflowmetry testing for?

A uroflowmetry test is sometimes recommended if you have trouble passing urine or if you show any signs of any urinary condition, such as incomplete bladder emptying after urination, urinary incontinence, or leaking after urination.

The most common causes for urinary conditions are:

• Urinary tract infections (UTIs) - urethritis, prostatitis, cystitis, vaginitis
• Kidney stones
• Urethral stricture
• Benign prostate enlargement (BPE)
• Bladder neck dysfunction
• Urinary tract tumour

How can I prepare for uroflowmetry testing?

It is important that you drink about a litre of water and that you do not pass urine before the test.
