Artifact Recognition and Solutions in Urodynamics
Artifacts occurring during the performance of urodynamic studies are observations or findings that are not naturally present in the patient’s normal micturition process, and are the result of the study process itself. They can arise from technical problems with catheters, electrodes, transducers, or other electrical equipment. The unnatural conditions of the urodynamic experience may trigger patient behaviors, such as psychogenic inhibition, making it challenging to evaluate voiding function. Here we characterize common pressure artifacts such as signal mismatch and drift of Pves and Pabd, EMG problems, and issues arising from spurious uroflowmetry and patient factors. Potential solutions to these technical problems are offered to facilitate a more complete, accurate, and useful urodynamic study.
