Bladder diary


More in this section


Keeping a bladder diary helps us to make an assessment of how your bladder is working. It gives us an idea of the amount you drink, the amount of urine your bladder can hold, and how often you pee (pass urine).

How to complete your bladder diary

Fill in the bladder diary as carefully as possible for 2 days in the week.

For each day, record what and how much you drink (in millilitres or cups), and when you drink it.

Use a jug to measure the amount of urine you pass. Record the amount on the chart.

If you leak urine, tick the column marked ‘wet’.

Every time you pee, please put a letter on the chart from the list below that describes how urgently you had to get to the toilet.


What each letter means
 A  I felt no need to pee, but did so for other reasons.
 B  I could wait to pee as long as necessary without fear of wetting myself.
 C  I could wait to pee for a short while, without fear of wetting myself.
 D  I could not wait to pee, and had to rush to the toilet in order not to wet myself.
 E  I leaked before I got to the toilet.
