Fistulography

 

a method of roentgenologic examination of a fistula. An X ray is taken after a contrast medium is introduced under aseptic conditions through the external opening of the fistula. The contrast medium is usually an aqueous or oil solution of an organic compound of iodine, such as Urotrast or Verografin (diatrizoate sodium), or iodized oil. Fistulography is used to determine the length, shape, and direction of a fistula and its relation to a hollow organ (such as stomach, intestine, or bile duct), as well as to a foreign body or a focus of inflammation; this enables the physician to select the appropriate therapy.
