Overactive Bladder Diagnosis
One of the first steps toward diagnosing OAB is to keep a urination diary. Documenting symptoms - including urgency - can help your urologist make the proper diagnosis.
A urinalysis (UA) must be performed to rule out infection and to look for glucose (sugar), blood, white cells or difficulty concentrating the urine (specific gravity). After urination, residual urine is also checked using an ultrasound or catheterization. In some patients, a urine cytology or endoscopy (cystoscopy) of the bladder is warranted. It is sometimes useful to perform bladder pressure testing using cystometry (CMG) to document bladder (detrusor) over activity during filling and exclude obstruction. Imaging of the urinary tract with cystogram, computerized tomography (CT) scan or magnetic resonance imaging (MRI) is rarely needed.
