Overactive bladder (OAB) is a clinical symptom complex whose hallmark is the symptom of urinary urgency, usually accompanied by frequency and nocturia, with or without urgency incontinence.
Historically, urodynamics (UDS) evaluation has not been recommended in the initial evaluation of OAB, since it is defined primarily by clinical symptoms. As the pathophysiology of the OAB complex has become more clearly elucidated from recent studies, the role of UDS has again become a topic of discussion as a tool that can provide objective data to reflect these new findings. The utility of UDS in the diagnosis and treatment of OAB is still evolving, but in certain clinical scenarios, especially when empiric treatment has failed, it can provide definitive information that can identify associated pathologies and/or alter the treatment course. Herein, we will discuss the current literature regarding use of UDS in OAB patients and offer our own opinions as to its use.
