title: Assessment of residual urine volume during routine cystography and urography.
abstract: The residual urine volume after voiding was measured by a modified cardiac formula in patients who were examined by means of voiding cystography. The reliability of the formula was tested in an experimental situation. A high degree of accuracy in correlating computed volumes with instilled volumes was found.
