What is a flow test?
This test records the rate at which you pass urine and the amount you pass. It is carried out to assess the changes you have experienced in your usual flow of urine. To record this information, you will be asked to pass urine into a special machine, within a private room.
What is a bladder scan?
After your flow rate test, it will be necessary to scan your abdomen to determine whether you have emptied your bladder fully or retained some urine. This is a painless procedure. A small amount of gel is put on your abdomen and an ultrasound probe is used to obtain a picture of your bladder onto a screen. Any residual urine is shown on the screen and the volume is calculated.
Are there any risks involved?
There are no side effects to either of these tests and you can resume your normal activities immediately afterwards.
On the day of the procedure
-

**Arriving at the department with a full bladder will reduce your waiting time, although if you experience problems such as frequency or urgency, we understand it may be difficult for you to travel with a full bladder.**
What happens after the procedure?
After your flow rate test and scan, the nurse or doctor will speak to you or write to you about the results and any subsequent treatment and/or any necessary further appointments.
