Urography is performed to examine the condition of the kidneys: the patient is injected with contrast and x-rays are taken. For this reason, a similar method of studying the condition of the kidneys is called contrast urography.. The method is based on the ability of the injected contrast to delay X-rays: first, the dye accumulates in the kidneys, after which it is excreted by the organs of the genitourinary system, and this makes it possible to assess their condition.

Assign urography to patients with suspected kidney stones, urinary tract infection, in the presence of blood in the urine, which may signal acute inflammation or cancer, with damage to the urinary tract.

Distinguish survey, intravenous, excretory urography.

Plain urographyThis is the name of the x-ray examination of the kidneys, with the help of which tumors, parasitic diseases, foreign bodies and stones in the kidneys are diagnosed, and often this is the first examination that is prescribed to the patient if he is suspected of having pathologies of kidney function.

Plain urography makes it possible to study the state of the kidneys, starting from their upper poles and up to the beginning of the urethra.

Survey urography is prescribed in cases where it is necessary to additionally study the bones of the skeleton, the shadows of the kidneys, their shape and location, to assess the general condition and functionality of other urinary organs: the bladder, ureters.

Excretory urography The technique is based on the excretory function of the kidneys and most of the pictures are taken at the moment when the kidneys began to secrete contrast.

Excretory urography allows you to assess the intensity and time of filling the pelvis, bladder with liquid, the shape, size, uniformity, location of stones and found neoplasms (cysts, tumors), structural features of the bladder, other organs of the urinary system.

Intravenous urography This method of contrast urography consists in the fact that a patient with an empty bladder is injected with contrast and pictures are taken while the kidneys take it from the blood and accumulate it: in the first two minutes, after 4-5 minutes. and after 7 minutes. after contrast injection.

Radiographs obtained after intravenous urography show the kidneys, pelvis and ureters, bladder, prostate gland. With the help of intravenous urography, tumors, cysts, stones, expansion of the cavities of the kidneys (hydroureter, hydronephrosis), pathological wrinkling and stretching, hyperplasia of the tissues of the genitourinary system can be detected.
