title: Urodynamics in the evaluation of overactive bladder.
abstract: Overactive bladder (OAB) is a clinical syndrome characterized by urinary urgency, frequency, and nocturia with or without accompanying urinary incontinence. Thus, using this operational definition based on symptoms at presentation, urodynamic testing is not required for an initial diagnosis of OAB. An increasing body of evidence suggests that, although there is a relationship between the urodynamic finding of detrusor overactivity and OAB, these are quite separate findings, and successful response to nonsurgical and surgical interventions for OAB does not depend on finding detrusor overactivity on urodynamic testing. The role of urodynamics in the setting of OAB is not well defined at present, but there are several clinical scenarios where such testing may be useful. However, at this time, the evidence to support their routine use in patients with OAB is limited.
