Formerly, the examiner simply observed the act of voiding, noting the strength of the urinary stream, and drawing inferences about the possibility of obstruction of the bladder outlet. In the 1950s, it became possible to observe the lower urinary tract by fluoroscopy during the act of voiding, and in the 1960s, the principles of hydrodynamics were applied to lower urinary tract physiology. In the 1970s, videourodynamic was introduced, where fluoroscopy was incorporated with the pressure measurements to adequately assess both anatomy and function.
