Overactive bladder: why we ask for a diary before any treatment
Urgency, frequency and getting up at night are symptoms, not a diagnosis. Three days of a bladder diary tell a urologist more than any single test. What it is, how to keep it, and what happens next.
The symptoms
A sudden, hard-to-defer need to pass urine; going more than eight times a day; waking more than once a night; and, for some, leaking before reaching the toilet. Together they are called overactive bladder. They are common, under-reported, and in most cases treatable.
Why the diary comes first
For three days you record what you drink, when you pass urine, roughly how much, and any urgency or leaks. It takes a minute each time and it answers questions no scan can: whether the bladder holds a normal volume, whether night-time output is simply high, whether caffeine or evening fluids are the driver. It often changes the treatment before any medication is considered.
The tests
- Urine analysis to exclude infection and blood
- Ultrasound of the bladder, with a measurement of what is left after you pass urine
- Flexible cystoscopy, a look inside the bladder with a fine single-use scope under local anaesthetic gel, when symptoms suggest it
- Urodynamics, which measures pressure and flow while the bladder fills and empties, for cases that have not responded to first-line treatment
Treatment, step by step
- Bladder training and pelvic-floor work, guided and reviewed
- Fluid and caffeine adjustment based on the diary
- Medication that calms the bladder muscle, with attention to side effects
- Bladder-wall injections of botulinum toxin, a prescription-only medicine, for an overactive bladder that has not responded to tablets. The effect lasts six to nine months and can be repeated.
For men
Similar symptoms can come from the prostate rather than the bladder. The assessment separates the two, and the treatment differs. Our PSA article covers the prostate side.
When to be seen quickly
Blood in the urine, pain, fever, or symptoms that began suddenly. See Blood in the urine: never just an infection until proven.
