A Uroflow measures the flow and force of your urine stream. This test is often performed in patients who have obstruction in normal flow of urine or problems with urination.

To perform the test properly, it is important that you arrive for your appointment with a normally full bladder and feel the normal urge to urinate. If you are asked to give a urine sample by the person who checks you in, tell them you are having a uroflow test and will need to wait to give the sample to the technician at that time. If you become extremely uncomfortable from the urge to empty your bladder before you are brought into an exam room, please inform the receptionist who will inform the technician.

You will be taken to a private restroom and will be instructed to urinate into a special toilet that is equipped to electronically measure the volume and flow of your urine. A paper recording of the urine flow will be generated. The goal is to have you urinate as you normally would. Forcing urination with a partially full bladder or waiting until your bladder is overfull, distended, and uncomfortable can give inaccurate results on the uroflow test.

There is no special preparation required for the test beyond arriving to clinic with a normally full bladder. You will not experience any pain or discomfort. The results of this test will help your Urologist determine the best treatment option for you.

You may resume your usual daily activities immediately following the uroflow test.
