How is Overactive Bladder diagnosed?

One of the most useful steps in diagnosing OAB is to fill out a frequency-volume chart (or bladder diary). This is a chart on which you record how often you go to pass urine and the volume of urine passed. You should also record when you have something to drink, and any episodes of incontinence.

The doctor will also take a detailed account of your bladder problems, do a careful examination, and perform a urine test and a scan of the bladder in the outpatient clinic. 90% of the time, this is all that is required to diagnose the problem and suggest appropriate treatment. Sometimes, further tests may be needed (eg cystoscopy or urodynamics).
