What to do before kidney ultrasound

What should be done before an ultrasound of the kidneys so that after the examination the doctor can make the correct diagnosis? First of all, it is necessary to eliminate various obstacles from the gastrointestinal tract and other areas of the abdominal cavity. Only in this way will the sonologist be able to determine the current state of the patient's kidneys. An ultrasound examination is recommended annually, regardless of health condition. Read more about preparing for an ultrasound of the kidneys and will be discussed in this article.

Why do you need to carry out an ultrasound

Ultrasound diagnostics are used for the following reasons:

• pain in the lumbar region;
• discoloration of urine;
• unsatisfactory results of urinalysis, pain when urinating;
• the appearance of edema;
• development of inflammatory processes (cystitis, pyelonephritis, and so on);
  

  Pyelonephritis - what is it, why does it occur

• mechanical damage to the urinary system or congenital abnormalities;
• the development of hypertension. In this case, the doctor may prescribe an ultrasound of the kidneys to examine the renal arteries;
• nephrolithiasis (formation of kidney stones in a patient);
• poor metabolism;
• the patient suffers from gout or diabetes mellitus;
• pathology of the reproductive system.

On a note! In parallel with ultrasound diagnostics, the doctor may prescribe an examination of other internal organs. These can be organs of the reproductive or digestive system - it all depends on the patient's condition and the manifestation of symptoms.

What the procedure shows

Thanks to this study, doctors can identify the following syndromes and pathologies:

• glomerulonephritis (kidney damage of the patient of an immuno-inflammatory nature);
• the formation of air bubbles in the calyx-pelvic system of the kidneys;
• various inflammatory processes, for example, pyelonephritis;
• narrowing of the ureter;
• pathological changes in the tissues in the kidneys;
• urolithiasis disease;
  

  Urolithiasis disease

• paranephritis and perinephritis (fluid accumulates in the perirenal tissue or inside the patient's kidney itself);
• kidney abscess;
• malignant or benign formations;
• cyst;
• nephroptosis, in which the kidney is displaced downward;
• inflammation of the blood vessels;
• pathological expansion of the renal calyx and pelvis (hydronephrosis);
• narrowing of the ureters;
• congenital kidney disease.

This is not the whole list of pathologies and pathological conditions that can be detected by ultrasound examination of the kidneys. Provided that the ultrasound is carried out correctly, the doctor will be able to determine diseases not only of the kidneys, but also of other internal organs of the patient.

Preparation for ultrasound of the kidneys

Detailed information about preparation for the procedure should be provided by your attending physician, because only he is familiar with the state of health of patients. As a rule, preparation for an ultrasound of the kidneys consists of several stages: a therapeutic diet, we will take pharmacy drugs, rejection of bad habits, a drinking regimen, and so on. Let's consider each of the stages separately.

Nutrition

If you are about to have an ultrasound of the kidneys or other internal organs, the doctor will ask you to stop using the following products:

• rich broths;
• dairy products;
• fresh fruits and vegetables;
• beans, peas and other legumes;
• foods containing fast carbohydrates (chocolate, cookies);
• carbonated drinks;
• alcoholic products.

About 3 days before the ultrasound examination, you can add to the daily diet:

• chicken eggs (only boiled and not more than 1 piece per day);
• beef liver;
• rabbit or chicken;
• various types of cereals (oat, buckwheat, pearl barley);
• low-fat cheeses;
• green tea without sugar. It is not recommended to drink strong coffee and tea, as they are irritants to the intestines.

Important! Carry a small container of clean water with you at all times to drink in small sips throughout the day. At the slightest urge to go to the toilet, you do not need to endure - this will have a bad effect on the state of urea and may distort the results of the diagnosis.

Be sure to contact your doctor if you have any questions or concerns about the upcoming procedure. The doctor will assess your condition and, if necessary, postpone the examination for another time.

Drug preparation

If flatulence or other problems with the functioning of the digestive system appears, the doctor may prescribe medications to prepare for an ultrasound of the kidneys. As a rule, enzyme agents are prescribed that stabilize the production of certain enzymes in the body, which in turn improves digestion and prevents the formation of gas in the intestines the patient.

Below are the effective remedies that are most often prescribed in preparation for an ultrasound examination.

Table. Review of drugs prescribed before kidney ultrasound.

Name of the drug, photo	Description
Espumisan	An excellent medication included in the group of defoamers. It is prescribed for increased gas production. The effect of the drug is to reduce the surface tension of gas bubbles, which leads to their rapid disintegration.
Smecta	An adsorbent drug used in medicine to improve the functioning of the digestive system. Its action is to stabilize the mucous barrier, as a result of which the body is cleared of feces. Doctors recommend it for use in preparation for an ultrasound of the gastrointestinal tract.
Neosmectin	It is also an adsorbent with high activity. The active component of this drug is dioctahedral smectite. There is no negative effect on the patient's intestinal motility while taking Neosmectin.
Festal	The preparation contains bovine bile and hemicellulases, which makes it an effective tool for normalizing the gastrointestinal tract. Regular intake of Festal improves the breakdown and absorption of foods. It is also taken in preparation for an ultrasound examination of the kidneys.
Mezim Forte	Pancreatin, a medicinal substance of natural origin, acts as an active component of this drug. Contributes to the normalization of the digestive processes in the body (the intestinal absorption of proteins, carbohydrates, fats and other useful substances improves).
Bobotik	A medical drug of the carminative type, simethicone acts as an active ingredient. The tool has a positive effect on the work of the intestinal tract, destroying the walls of gas bubbles. Bobotik is used in medicine as an effective defoaming agent. It is used for colic, flatulence, and also for the prevention of bloating.

If a person who is to undergo an ultrasound examination suffers from frequent constipation, then the doctor must take appropriate measures to eliminate this ailment. The fact is that the results of the diagnostic procedure can be affected by hardened feces that are in the body. They interfere with the passage of ultrasound waves, therefore, before the ultrasound scan, the patient is prescribed medications based on lactulose or senna extract.

If you have been taking diuretics for a long time, then before starting preparation, you must definitely inform your doctor about this. He should postpone the procedure for a certain time or recommend that you stop taking diuretics. The fact is that they cannot be taken before an ultrasound scan.

Preparing pregnant women

Diagnosing women during pregnancy, or rather, preparing for it, practically does not differ from preparing for an ultrasound of the kidneys of an ordinary person. There are no contraindications for ultrasound examination, therefore, the procedure is carried out regularly throughout the entire period of pregnancy.

The preparation must be approached correctly, that is, about 3 days before the diagnosis, you need to completely exclude from the diet foods that can provoke stagnant processes or fermentation in the digestive organs systems. It is also necessary to follow the drinking regimen prescribed by the doctor. On the day of the procedure, you need to continue drinking water, but you should refuse to eat (do not eat anything 2-3 hours before the start of the diagnosis).

On a note! Cleaning procedures can only be carried out under the supervision of the attending physician. As a rule, he prescribes enemas, but only on the condition that the pregnant woman does not have problems with the genitourinary system. Otherwise, her health may be in danger. All your actions and manipulations while carrying a child must be coordinated with a doctor.

Features of the ultrasound

Ultrasound examination is perhaps the most painless and harmless diagnostic method. For ultrasound, the patient must lie on the couch. If the doctor examines the kidneys, then the patient should lie on his back, on his stomach or on his side (depending on the situation). In rare cases, the diagnosis of the kidneys takes place in a standing position, and the patient must inhale and exhale intensively at this time. As a rule, this position is required to exclude nephroptosis.

A special gel is applied to the body, which has conductive properties. The gel improves skin contact with the device used. After that, the doctor conducts a transducer over the treated area. The emitted ultrasonic waves during the operation of the device are not audible to humans. They are sent to the kidneys or other diagnosed organs, and the received signal is displayed on the computer monitor in the form of a picture.

When studying the data obtained, the doctor determines the contours of the internal organs, takes measurements of the kidneys. Based on this, he makes a printout. The procedure takes about 10 minutes, but during the procedure the patient does not feel any discomfort. The only thing you might not like is the conductive gel. It is quite cool and humid, so especially impressionable people may experience minor discomfort.

Decoding of the results obtained

As soon as the research procedure is completed, the doctor will issue a conclusion based on the results obtained. But it is not always possible for an ordinary person to decipher these data due to the large number of incomprehensible medical terms. In order to be at least a little aware and understand what the doctor's conclusion contains, you need to familiarize yourself with some points. For example, the contours of a healthy kidney must be even and with a clearly defined fibrous capsule.

In the presence of kidney stones no more than 5 mm in size, they can be detected when the echogenicity changes (the intensity of the reflection of the ultrasonic wave from the tissues). Often, experts call stones or sand formed in the kidneys an echogenic formation or echo. This is normal, but unfortunately, ordinary people do not know such terms. If you see a diagnosis of kidney microcalculosis in the results of the study, it means that sand has formed in the kidneys.

Also in the results you can see the diagnosis "severe intestinal pneumatosis." This can mean only one thing for the patient: the ultrasound must be repeated again, since the results of an earlier examination were not informative. This is due, first of all, to increased gas production. The gases accumulating in the patient's intestines create air cysts, but normally they should have been absorbed into the bloodstream. In this case, the doctor prescribes the intake of special drugs to combat increased gas production, and the whole process of preparation for a diagnostic examination begins anew. To prevent this from happening, you need to follow all the doctor's recommendations regarding preparation for the procedure.
