Any of a group of x-ray techniques used to examine the urinary system. A radioopaque substance is injected, and x-ray films are taken as the substance is passed through or excreted from the part of the system being studied. Some kinds of urography are cystoscopic, urography, intravenous pyelography and retrograde pyelography.

Radiography of a part of the urinary tract

An x-ray procedure to examine the kidneys and ureters. Comparisons can be made between both kidneys using a special dye. The size and shape of the bladder can also be determined using this procedure. Also known as an intravenous urogram (IVU)

MS = Radiography of any part of the urinary tract. AN = GEN only: prefer specific organ with /radiogr; NIM; /drug eff /rad eff permitted; do not use /util except by MeSH definition; DF: UROGR UI = D014567

X-ray examination of the urinary tract, particularly the upper parts, i.e. the kidneys and the ureters. More rarely it involves the lower parts, i.e. bladder and urethra. Since X-ray contrast media are excreted close to 100% via the kidneys, pictures of the kidney parenchyma (=tissue) can be taken after 2-4 min. Pictures of the collecting system (= renal pelvis + ureters) are taken 5-10 min after this. To keep the contrast-containing urine from running down to the bladder, to image the ureters better the lower stomach may be compressed by inflating a rubber balloon under tight straps.
