A critical evaluation of commercial urodynamics systems.

Abstract

A comprehensive protocol was developed for assessing urodynamics instrumentation and applied to eight commercial urodynamics systems obtained on short-term loan. Assessment covered the areas of design and construction, measurement accuracy, and software performance. The measurement performance of virtually all systems was found to be adequate for the application. The main areas of weakness were susceptibility to artefact, poor user-friendliness, and lack of physical ruggedness.
