ABSTRACT
Urodynamics is the study of urinary tract function and dysfunction with two main specific aims; to reproduce the patient’s symptomatic complaints and to provide a pathophysiological explanation for the patient’s problems. A full urodynamic investigation consists of: (1) free-flow rate assessment; (2) measurement of post-void residual urine; (3) filling cystometry; and (4) pressureflow study. These should proceed in the order described and each part of the study should be considered an integral part of the investigation, information provided from each section being collated with all others to give an accurate, objective evaluation of lower tract function.
