Bladder diary — three days, one sheet each.
When a doctor asks you to keep a bladder diary, the first question is usually what exactly goes in it. Here is a ready-made template with instructions — and what gets read from it in the end.
Bladder diary as a PDF
Four A4 pages: one page of instructions and three daily sheets with 22 rows each, columns for intake, urine volume, urgency, leakage and catheterisation, plus a totals box for each day.

A bladder diary is the simplest and often the most informative tool in urology. It costs nothing, hurts nothing, and gives something no snapshot in a consulting room can: how the bladder behaves across an ordinary day.
That is why it comes first when frequency, night-time voiding, incontinence or a weak bladder are the issue — and before any decision about medication or further investigation.
Instructions
How to do it properly.
- Three days, not one. Ideally two working days and one day off. A single day can be a fluke; hardly anyone keeps it up for a whole week.
- Change nothing. The most common mistake: suddenly drinking exemplary amounts or postponing trips to the toilet. Then you record a day you never actually have.
- Write it down immediately. Filling it in from memory in the evening makes it useless — you remember the striking moments and forget the ordinary ones. The sheet belongs by the toilet.
- Measure where you can. A measuring jug will do, or any container whose volume you have checked once. Mark estimates as estimates so it is clear later what was actually measured.
- Nights count too. Note every time you get up at night, with the time. The ratio of daytime to night-time volume is one of the most important figures there is.
- Leakage with circumstances. Not just whether but when: coughing, standing up, on the way to the toilet, while asleep. That is exactly how the forms of incontinence are told apart.

Which values count as unremarkable.
These figures are guides for adults, not thresholds. Deviations on their own mean nothing — they are a reason to look at it together.
| Measure | Usual range | Possible reasons for deviation |
|---|---|---|
| Fluid intake per day | 1,5–2 l | Much more drives frequency up; much less concentrates urine and irritates the bladder |
| Urine output per day | 1,2–1,8 l | Should roughly match intake; large gaps suggest measurement error |
| Voids during the day | 4–8 times | More often with an overactive bladder, urinary infection, caffeine or diuretics |
| At night | 0–1 times | More may point to nocturia, cardiac or renal issues, or sleep apnoea |
| Volume per void | 250–450 ml | Small volumes with an irritated bladder, very large ones with reduced bladder sensation |
| Largest single volume | up to 500 ml | Indicates functional bladder capacity |
Different yardsticks with a neurogenic bladder
After a spinal cord injury, or with multiple sclerosis or spina bifida, the diary is especially useful — but the ranges above do not apply. People using intermittent catheterisation work to fixed times rather than urgency, and the figure that matters is keeping each volume below a limit agreed with the care team. Excessive filling puts strain on the kidneys.
That is why the template has its own catheter column. It is also worth noting anything unusual — cloudy or strong-smelling urine — in the notes column; with urinary infections that is often the first sign.
Do not wait — get it checked
A diary is fine when there is time. With these signs there is not:
- Blood in the urine
- Fever with flank or back pain
- Unable to pass urine despite strong pressure
- Burning together with fever or chills
- A sudden marked change in bladder behaviour
- With a spinal cord injury: pounding headache and sweating — signs of autonomic dysreflexia
In these cases please seek medical help directly.
Paper or app?
Paper has a real advantage: it lies there in plain sight and reminds you by itself. For three days the template above is entirely sufficient, and many practices want to see exactly that.
Across weeks, though, paper gets tedious — adding up, sorting sheets, spotting trends. That is what Bladder & Bowel Manager is for: reminder timers, entries in two seconds, totals calculated for you, CSV export for the next appointment. Everything stays on your device.
