The Intravenous Urodynamogram

Abstract
Modifications to the intravenous urogram are described. It is suggested that the time has come to rationalise the standard procedure. If an evaluation of the lower urinary tract is required, the voiding films may be modified to provide an intranvenous urodynamogram. If an evaluation of the upper urinary tract is directed at a specific question, then the number of spot-films can often be reduced.
