ABSTRACT
Introduction: the variability of urodynamic measurements Urodynamics is the study of lower urinary tract (LUT) function by any appropriate method.1 Its purpose as usually stated is to reproduce LUT symptoms under controlled and measurable conditions so that their causes can be identified. In practice, however, there are only weak correlations between symptoms and urodynamic findings.2 The reasons for this weak association include the intrinsic variability of urodynamic parameters,2 not only from one subject to another but also within a single subject.
