title: Traces: making sense of urodynamics testing--Part 11: quantitative analysis of micturition via the voiding pressure flow study: pressure-flow nomograms.
abstract: The voiding pressure flow study is the gold standard for evaluating micturition. Part 10 of the Traces series described techniques for evaluating micturition via the voiding pressure flow study; it focused on interpretation of results qualitatively via inspection and classification of flow pattern, detrusor contraction amplitude and duration, pelvic floor muscle response to voiding, and urethral resistance. This article discusses quantitative analysis of the voiding pressure flow study using nomograms that measure the magnitude of urethral resistance (bladder outflow obstruction) and/or detrusor contraction strength.
