Practical Interpretation and Application of Urodynamic Findings

Abstract

Proper reading and interpretation of a pressure flow urodynamic tracing should be performed in a systematic fashion. Unfortunately, there is no universally agreed upon approach to the interpretation of a pressure flow urodynamic study. Using the functional classification of voiding dysfunction as a framework, the pressure-flow tracing can be dissected into a filling/storage portion and an emptying portion. Important aspects of the urodynamic study can sub-classified within each of these phases. Conveniently, each of these aspects can be titled with a “C” thus providing the 9 “C’s” of pressure-flow urodynamics interpretation and reporting. Such a scheme allows a complete and uniform approach to the interpretation of the urodynamic tracing. This chapter will provide a framework with which the practitioner can approach and interpret the pressure-flow urodynamic (PFUD) study.
