Flow rate and frequency volume chart

A urine flow rate is a simple test to see how fast you pass water. For the test to be effective, it is important that you attend with a full bladder. Following the urine flow test, your bladder will be scanned to check if you empty your bladder completely. Please can you read the information below carefully and complete the frequency volume chart (which you can download at the bottom of the page). This will help us to have a clearer indication of your fluid input and output for three days prior to the test. It is important you bring this with you to your appointment.

Instructions

Before starting to fill in the chart you will need a small plastic measuring jug, with millilitres marked on it. It is best to choose two or three days when you know you will not be particularly busy (e.g. over a weekend). They do not need to be consecutive days.

Type of drink – please write what sort of drink you had in this column (eg. tea, coffee, water).

Amount of drink – before you start, and to avoid having to measure every drink you have, please use the jug to measure the volume (amount of liquid it holds) of your usual cup/mug/glass and keep a note of these figures in the table below. Please then enter the volume in the appropriate column, when you have a drink. The jug can then be used to measure the volume of urine passed.

Amount of urine passed – every time you pass urine, measure the amount in the measuring jug and record the amount in mls (millilitres). It is important to record the amount of urine passed during the night time as well as the day time and enter it in the appropriate column.

Wet/pads changed – please write wet every time you are wet and pad every time you changed a pad in the corresponding column, if this applies to you.

Please also note on the chart at what hour you woke up (by writing woke) and when you went to bed (by writing bed).
Complete the chart for three full days and bring it to your next appointment.
