ABSTRACT
Urodynamic investigation is a functional assessment of the lower urinary tract to provide an objective pathophysiologic explanation for the symptoms and dysfunction of the urinary tract. Urodynamic studies comprise a series of tests, and the appropriate test should be selected and performed in an attempt to answer a question on the target function to be evaluated. The information provided by urodynamic studies may be useful in establishing the etiology of the dysfunction and may help in selecting the most appropriate intervention. Prior to urodynamic investigation, a medical history, physical examination, and voiding diary should be obtained, as such information is necessary in order to select the appropriate studies and anticipate which events might take place during the urodynamic investigation. Unfortunately, urodynamic testing is not a set of laboratory values like blood chemistry values, but rather a physiologic testing that may be affected by several factors. Presence of the clinician during the studies is essential for successful interpretation of findings.
