Validation of a Real-time Urodynamic Measure of Urinary Urgency

Urinary urgency is a key symptom of overactive bladder syndrome (OAB) and may be more bothersome to a patient than the symptom of urinary frequency. Unfortunately, controversy continues to surround the term 'urgency' and there is no good tool to evaluate the severity of urgency. This fact has constrained the performance of clinical research in this field. The cause of urinary urgency is not fully understood and may vary from patient to patient. Although clinicians regularly obtain measures of bladder sensation during cystometry, little attention has been paid to the patient experience of urinary urgency. In this study, the researchers will use a non-significant risk device (i.e., an Urgeometer) to measure urinary urgency in women with overactive bladder.
