Nephroscintigraphy of the kidneys, its organization and possible consequences
Nephroscintigraphy of the kidneys is a radioisotope examination, which makes it possible to reveal the location, size, shape of the kidneys, to identify foci of their damage and to assess the presence of a properly functioning renal parenchyma.
This is important!
A radioactive preparation is injected intravenously and it is absorbed by the cortex in the kidney, and is removed from the body rather slowly. Fixing the radiation of such a substance helps to obtain a series of images.
The purpose of the diagnostic method
Most diagnostic methods, such as X-ray examination, ultrasound examination and computed tomography help to obtain data on the structure of the kidneys, and radionuclide examination helps to study the work of the kidneys.
Usually renal scintiraffia is prescribed to patients with acute or chronic form of kidney failure, blockage of the urinary canals, stenosis of the kidney artery, donor kidney, kidney trauma, kidney vascular lesions or other congenital kidney pathologies.
Preparatory activities
No special preparation is required for nephroscintigraphy and for some types of examination patients need to immediately drink additional fluid before the diagnosis and then empty the bladder.
If other radionuclide diagnostics were previously implemented, then it is required to refuse for some time to organize a repeated examination to prevent the accumulation of radioactivity in the body.
Diagnosis of
Nephroscintigraphy of the kidney is performed in a special department of the nuclear medicine hospital. The patient is placed directly in front of the gamma camera or under a gamma camera. A gamma camera is a specialized equipment that captures the radiation that comes from the medicine injected into the body that has accumulated in the patient's body. This is how the image is formed.
Intravenously the patient is given a radioactive preparation. Immediately after the injection, a survey is organized - an evaluation of the blood circulation in each of the kidneys. The sequence of images is obtained after a specific period of time, depending on the radioactive preparation used. Scanning of the organ is organized to determine the rate of passage of blood filtration in the renal glomeruli.
Consequences of
After the organization of nephroscintigraphy patients can return to a normal lifestyle, because most of the radioactive drugs are subsequently excreted by the urinary system. In connection with this, the increase in the volume of consumed liquid after scintigraphy makes it possible to shorten the time for the removal of radioactive substances from the human body.
This is important!
Nephroscintigraphy of the kidneys shows the state of the kidneys in accordance with the patient's age group and the state of his health. Also, the location, size and configuration of the organ is revealed.
Diagnosis complications
Studies that rely on nuclear medicine are considered to be completely safe. In contrast to the use of certain types of contrast agents in the X-ray examination of the kidneys, radioactive preparations only in exceptional cases cause side effects.
The long-term effect of the radioactive drug effect is absent, because they soon break up and do not have any direct functional effects on the tissues in the human body.
When implementing the introduction of radioactive medications, blood pressure may rise for a while or, conversely, decrease. There are also strong urge to urinate.
Such consequences are considered normal and quickly pass independently without medical intervention.
