Mar 17, 2018
X-ray examination of the kidneys in many situations becomes crucial in the diagnosis of a particular pathology.
When the inserted contrast medium reaches the kidneys, it fills their pelvis and calyx, then the ureters, after which a whole series of shots is taken. Intravenously, a contrast agent is administered in the excretory type of urography and infusion urography. In the latter case, the contrast is introduced into the vein gradually with the help of a dropper. The infusion type of urography makes it possible to obtain more clear images.
In the implementation of retrograde uropielography, a contrast agent is injected through a special catheter through the canal to the bladder, then penetrates up into the ureters, pelvis and kidneys.
The most common species is excretory urography.
X-ray examination of the kidneys makes it possible to diagnose a variety of pathologies of the urinary system. You can establish the presence of congenital abnormalities in development, the absence of the kidney, its doubling, unusual arrangement of the body, too large or too small a size. With urolithiasis, stones can be examined, and it is also possible to diagnose tumor neoplasms in the kidneys. Urography also allows us to distinguish the length, shape and location of the ureters, their tumor, if any, and the condition for which urine is reversed into the ureters from the bladder.
Retrograde uropielography allows you to see changes in the shape and size of the bladder and its tumor.
Indications for diagnosis
The main indications of the urography include:
- Systematic damage to the urinary system by infections.
- Signs of development of renal colic.
- The presence of blood in the urine.
- Symptoms of urolithiasis.
