Urine flowmetry measurements

The uroflowmetry test is performed to measure the amount of urine voided and the speed of urination. It will help your doctor identify the cause of difficulty with urination or slow urine flow.

Measuring the maximum and average speed of urine flow will help determine how well your urinary bladder and sphincter muscles are functioning and if there is any kind of obstruction to the flow of urine. It can also help in identifying an enlarged prostate. The conditions that affect urine outflow include:

  • Enlargement of the prostate gland
  • Bladder cancer
  • Prostate cancer
  • Blockage of the urinary tract
  • Urinary tract infections
  • Bladder dysfunction
  • In preparation for the urine flowmetry, you should ideally not urinate for several hours and drink plenty of water to ensure you can urinate during the test. You must also inform your doctor if you are pregnant and about what medicines or supplements you may be taking. You will need to urinate into a special toilet or funnel which will be connected to an electronic device that measures the quantity of urine and the speed of urination.

    Depending on your condition, the test may have to repeated on several consecutive days. Your doctor will study the results and develop a treatment plan specific to your condition. There are no risks or complications associated with this procedure.
