Nephroscintigraphy. Prices, reviews, ratings
General information
Such popular diagnostic methods as ultrasound, CT and radiography make it possible to assess the structure of the kidneys, shape, size, but only nephroscintigraphy helps to fully examine the functioning of the kidneys and the features of their work.
Procedure
Preparation
No special preparation measures are required, except for drinking fluids before the test to empty the bladder.
Nephroscintigraphy procedure
There are two types of kidney scintigraphy - static and dynamic.
Statistical kidney scintigraphy makes it possible to assess the functioning of the renal parenchyma and changes in its work as follows:
- intravenous administration of a certain amount of tubulotropic drug;
- scanning the kidneys after 40-60 minutes and obtaining images from different angles simultaneously, which makes it possible to determine the location of the excess or, conversely, decreased accumulation of the administered substances.
Dynamic nephroscintigraphy is considered more effective, as it makes it possible to fully control the process of passage of a radioactive drug through the body, from the kidneys to the bladder.
During dynamic nephroscintigraphy, the entire urinary system is assessed as accurately as possible in the following way:
- Intravenous administration of a radioactive drug;
- Registration of radioactivity over the kidneys using a gamma camera:
- appearance of an image of the renal parenchyma (on average after 4 minutes);
- entry of the drug into the calyceal-pelvic sphere;
- filling of the bladder;
- obtaining computer graphic images of the kidneys.
The results obtained make it possible to fully assess the state of the kidneys, make a correct diagnosis and prescribe the necessary course of treatment.
Rehabilitation period
All radioactive drugs used are present in the body for a short time. Often the patient is advised to increase the volume of fluid consumed to ensure the fastest possible exit of diagnostic products from the body.
Complications
As a rule, there are no serious complications after nephroscintigraphy. The following side effects are quite normal after the examination:
- increased or decreased blood pressure;
- increased frequency and increased urge to urinate.
Indications
Nephroscintigraphy should be performed in the following cases:
- acute or chronic renal failure;
- obstruction of the urinary tract (difficulty in the outflow of urine);
- renal artery stenosis;
- a kidney transplanted to the patient (donor kidney);
- renal injuries of any nature;
- lesion of the renal vessels;
- arterial hypertension;
- reflux nephropathy;
- suspected tumor-like neoplasms.
Contraindications
Often, nephroscintigraphy is not recommended for pregnant women, mothers who are breastfeeding, and people who are allergic to the drugs used during the procedure.
If any other radionuclide study has been performed previously, nephroscintigraphy is prohibited in the near future in order to avoid oversaturation of the human body with radioactive elements.
Prices and clinics
Nephroscintigraphy of the kidneys, both static and dynamic, is not performed in all medical institutions.
