former name for intravenous urography.

intravenous pyelography (IVP)

a radiographic technique for examining the structure and function of the urinary system. A contrast medium is injected intravenously, and serial x-ray films are taken as the medium is cleared from the blood by the kidneys. The renal calyces, renal pelvis, ureters, and urinary bladder are all visible on the radiographs. Tumors, cysts, stones, and many structural and functional abnormalities may be diagnosed with this technique. Fasting and bowel cleansing with a cathartic or an enema before the procedure improve visualization of the urinary tract. The patient may also be asked to void immediately before injection of the contrast medium to prevent dilution of the medium in the bladder and immediately afterward to check residual urine in the bladder. Also called descending urography, excretory urography, intravenous urography, pyelography.

intravenous pyelography

Imaging An imaging study of the transitional mucosa of the urinary tract after IV injection of a radiocontrast that concentrates in urine; an IVP outlines the renal pelvis, ureters, and bladder

intravenous pyelography

A method of X-ray visualization of the drainage systems of the kidneys and the URETERS by giving an INTRAVENOUS injection of a radio-opaque substance that is rapidly excreted in the urine. The injection is followed by a series of X rays taken at intervals. These show the shape of the internal bore of the urinary drainage channels.

intravenous feeding
see intravenous infusion (below).
intravenous infusion
administration of fluids through a vein; called also phleboclysis, venoclysis and intravenous feeding. This method of feeding is used most often when a patient is suffering from severe dehydration and does not drink fluids because it is unconscious, recovering from an operation, unable to swallow normally, or vomiting persistently. Prolonged feeding of patients with chronic intestinal dysfunction can be accomplished by total parenteral nutrition.
intravenous pyelography


radiography of the kidney and ureter after injection of a contrast medium, introduced by the intravenous or retrograde method. Preparation of the animal for pyelography includes clearing the intestinal tract of as much fecal material and gas as possible so that there can be adequate visualization of the urinary tract structures. Called also intravenous pyelography (IVP).
