Urodynamic Evaluation of the Bladder and Pelvic Floor

Abstract

Pelvic floor disorders including lower urinary tract dysfunction are common, and may be evaluated by urodynamic tests, such as cystometry, uroflowmetry, pressure flow studies, electromyography, and video-urodynamics. These urodynamic tests provide objective information regarding the normal and abnormal function of the urinary tract and pelvic floor, and provide a better understanding of the pathophysiologic processes that cause lower urinary tract symptoms. This article describes typical urodynamic studies and their roles in the evaluation of common pelvic floor disorders, including stress urinary incontinence, overactive bladder, and pelvic organ prolapse. © 2008 Elsevier Inc.
