Overactive Bladder (OAB) is a syndrome characterized by symptoms of urinary urgency, often with urinary symptoms, with or without urge incontinence; urodynamically, it can manifest as Detrusor instability, or detrusor overactivity, or other forms of urethral-vesical dysfunction. OAB has no clear etiology and does not include symptoms due to acute urinary tract infections or other forms of localized lesions of the vesicourethra.
