Ultrasound Of The Kidneys In Health And Disease

How the kidneys look on ultrasound is normal and how pathology is determined can be found in this article. Here you will find the basic principles that experienced doctors’ use in their work.

A normal view of the kidneys on ultrasound

A complete ultrasound examination having high ultrasound scan cost of the kidneys includes an assessment of the location, orientation, axis, size, and echogenicity of the parenchyma, the contour, the nature of the centrally located echogenic disk and the lack of visualization of the proximal ureter. Normally, the kidneys are located in the retroperitoneal space along with the lumbar muscles and are oriented parallel to their course. They occupy an oblique position, and the upper pole is located dorsal to the lower pole.

The size of the kidney depends on the age; it is measured between the two poles and compared with known nomograms. From the point of view of ultrasound of the kidneys, the most important adjacent organ on the right is the liver, and on the left is the spleen. During the first few months of life, the kidney parenchyma may be iso- or hyperechoic compared with the liver or spleen, and then it becomes hypoechoic.

The cortex can be differentiated from the cerebral bylines, reflecting slight differences in echogenicity. The presence of cortico-medullary differentiation is an indicator of the normal structure of the kidney and the integrity of the parenchyma.

The contour of the kidney in children on ultrasound can be smooth, but often it has a lobed structure. Parenchymal lobules consist of a central pyramid covered with parenchyma of cortical substance and pillars located between the pyramids. With age, the lobed structure disappears, and the contour becomes smooth.

Abnormal development of the kidney on ultrasound

Anomalies or pathology of the kidneys in children can be divided into congenital and acquired, and anatomically- anomalies in the number, localization, vascular, parenchymal and abdominal systems.

One-sided kidney agenesis on ultrasound is often detected. Unilateral agenesis of the kidney is most often determined in children during an ultrasound scan conducted:

  • With urination problems;
  • When screening for related anomalies and
  • About unrelated pathology.

On ultrasound in the renal fossa is not defined as a bean-shaped structure, and it may be located intestines. The surrounding organs are usually not changed. In such cases, it is important to conduct an ultrasound examination of the pelvis to prevent kidney dystopia. In infants, the adrenal glands are visualized in a normal anatomical position.

Kidney dystopia on ultrasonography

The kidneys begin their embryonic development in the large pelvis with the pelvis oriented anteriorly, and then they migrate to the renal fossa and complete the medial rotation by the 6th week of gestation. This process can be interrupted at any stage.

Renal vein thrombosis with an ultrasound scan

Ultrasound done by professional Ultrasound Clinics has a high diagnostic value for suspected renal vein thrombosis. Risk factors include dehydration, birth injury, and sepsis. During the acute phase, marked edema develops, and an ultrasound examines an increase in the kidney with a loss of corticomedullary differentiation. Due to edema at an early stage, the parenchyma looks hypoechoic, but with the progression of fibrosis, it becomes hyperechoic. Thrombi of small vessels look like radiant linear echogenic bands in the parenchyma. Atrophy and calcifications are visualized at a late stage in the thrombus localization zone. When color Doppler on ultrasound, there is a lack of venous blood flow.

Myths And Truth About Prenatal Screening

Prenatal screenings cause a lot of conflicting opinions and feedback. Someone is convinced of their necessity; others are convinced of their complete inexpediency. What kind of research is this, and should all pregnant women really take them? To understand this issue, let's weigh the pros and cons and separate the existing myths from the objective data of scientific medicine.

The argument "against" number 1: ultrasound harm the baby

There is a fairly common opinion that Pregnancy Ultrasound negatively affects the nervous system of a child, annoys him - during the examination, children often try to hide from the apparatus, cover their heads with hands. Therefore, children whose mothers regularly performed ultrasound during pregnancy are more restless than babies whose mothers have refused ultrasound diagnosis. Is it really?

According to doctors, ultrasound cannot cause the baby absolutely no harm - modern equipment is absolutely safe. Therefore, official medicine insists that absolutely all pregnant women should undergo an ultrasound. Indeed, the timely diagnosis allows, firstly, to see the full picture of the course of pregnancy, and secondly, if necessary, to correct certain problems.

Especially important are the data obtained on ultrasound of the first prenatal screening (at 11-13 weeks of pregnancy). During this period during the study:

  • The number of embryos in the uterus and their viability are determined;
  • Put a more accurate period of pregnancy;
  • Gross defects are excluded;
  • Determines the thickness of the collar space - (that is, the amount of subcutaneous fluid on the back of the child's            neck is measured - in normal TVP should not exceed 2.7 mm);
  • The presence or absence of the nasal bone is investigated.

The argument "against" No. 2: a biochemical blood test gives an unreliable result

Many mothers are sure that it is impossible to make at least some reliable conclusions on one analysis- too many factors can affect the result. And, in part, they are really right. However, it is necessary to study the analysis process more closely in order to understand on what basis the doctor makes a conclusion. The second screening takes place at 18-21 weeks of pregnancy. This study includes a "triple" or "quadruple test. "Everything happens the same way as in the first trimester- the woman again takes a blood test. Only in this case, the results of the analysis are used to determine not two, but three (or, respectively, four) indicators.

The argument "against" No. 3: "I have good heredity- I do not need screenings."

Some mothers do not see the point of going through screenings - all relatives are healthy, what problems could there be? Indeed, there are certain groups of women who are primarily recommended to undergo Pregnancy Ultrasound to identify possible pathologies in the development of a child. These are women over 35–40 years old (since after this age, the risk of developing abnormalities in a child increases several times) and expectant mothers with certain diseases (for example, diabetes).

Major Liver Disease During Ultrasound

Steatosis of the liver (different names may be: fatty hepatosis, fatty infiltration, fatty liver), which occurs on liver ultrasound, is an etiologically and pathogenetically heterogeneous syndrome, which is characterized by a prolonged and significant accumulation of triglycerides in hepatocytes. The main factor of steatosis is alcohol abuse, diabetes, obesity, unbalanced nutrition (protein deficiency), chronic diseases of the gastrointestinal tract, accompanied by impaired absorption (enteritis, pancreatitis, ulcerative colitis, etc.), chronic debilitating diseases (cancer, anemia, cardiac and pulmonary insufficiency, etc.), toxic (hepatotropic, medicinal) and bacterial factors.

Ultrasound test with a diffuse form of fatty hepatosis, as a rule, reveals an increase in the size of the liver, an unclear contour. The edges of the liver are rounded. Characteristic features include increased echogenicity of the parenchyma. Its structure is in most cases homogeneous, however, sometimes on the background of hyperechoic tissue, it is possible to detect areas of reduced reflection with uneven, fuzzy contours that do not deform the vascular pattern.

These are areas of unchanged parenchyma, which, as a rule, are detected in the portal fissure of the liver, in the projection of I, IV, V segments. The sound conduction of the liver is often reduced; the vascular pattern is depleted. In addition to diffuse, ultrasound of the liver also produces local and focal forms, when fatty infiltration extends only to limited segments and sectors of the liver, and sometimes manifests itself in the form of individual small zones, resembling focal education.

Ultrasound picture of fatty hepatosis does not always allow to clearly differentiate it from other diffuse organ lesions (chronic hepatitis, the initial stage of cirrhosis). Crucial importance in the diagnosis of steatosis and its delimitation from chronic hepatitis belongs to the puncture biopsy of the liver.

How does hepatitis show on ultrasound?

Acute hepatitis is an acute degenerative and inflammatory lesion of the liver. Hepatitis can be alcoholic or viral etiology, develop as a result of exposure to toxic or metabolic factors. The main ultrasound sign of this disease is hepatomegaly. In a significant number of observations, moreover, an increase in the size of the spleen is found. The contour of the liver usually remains clear and smooth.

Edges can be both sharp and rounded. In the severe course, accompanied by the presence of foci of necrosis, the parenchyma has a heterogeneous structure due to the appearance of multiple areas of reduced echogenicity alternating with fragments of unchanged parenchyma. With significant swelling of the liver tissue, its echogenicity is reduced to a greater extent.

Organ conduction is often increased; as a result, the vascular pattern becomes clearer, and the walls of the portal vein more contrasting. Detection of enlarged lymph nodes in the area of the hepatoduodenal ligament may be of some help in making a diagnosis.

As a rule, on ultrasound in chronic hepatitis, an increase in the size of the liver due to the right and left lobes is observed, a rounding of the edges and an increase in the angles formed by them can be observed. The contour of the liver often remains clear and smooth. The structure of the parenchyma is usually diffusely heterogeneous, the echo is increased, and the sound conductivity is reduced in most cases. There is also a progressive impoverishment of the vascular pattern. In chronic hepatitis, diffuse liver damage was found only in 2/3 cases, which, according to the ultrasound labs, is due to the absence in most cases of fairly pronounced fibrosis and/or steatosis.

What Ensures a Good Sonogram Image?

For a pregnant woman, the images of sonogram matters the most and why not? After all they give a sneak peek of what the baby may look like. In this age of social media many Ultrasound Clinic have also created online groups for sharing the ultrasound images which make the ladies drool over them. In the last 4-5 years elective ultrasound has become increasingly popular as more mothers want to see their baby’s face before he/she is born. And thanks to recent advances in technology, ultrasound machines can render 3D and 4D imaging that is more lifelike than ever before. But, there is something to be very specific about; that the two expecting mothers do not have the same wombs and the 3D images of sonogram does get influenced by the same. There are quite a lot of factors that influence the clarity of ultrasound photos. I am going to list the top 5 in order of importance below:

1.     The Location of the Placenta- Your placenta is the organ that develops inside your uterus during pregnancy that provides oxygen and nutrients to your growing baby. The placenta is attached to the uterine wall either in the front (called an anterior placenta), or in the back (a posterior placenta). If you have an anterior placenta, it will be over the top of baby’s face, making it harder to get clear photos. Therefore, the recommended timeframe to get 3D/4D imaging is at 28-34 weeks, before baby gets too big and squished into the placenta. If your placenta is posterior, it will be under the baby, and you can wait until 34-38 weeks to have your ultrasound. If you don’t know where your placenta is located, you can email us an ultrasound picture from your anatomy scan, and we can tell you.

2.     The amount of amniotic fluid- A higher amount of fluid present in the amniotic sac would ensure that the 3D/4D imaging is clear. Higher fluid levels are especially important if you have an anterior placenta because we need to have fluid between baby’s face and the placenta to be able to get images. To make sure you have fluid in the amniotic sac, it is recommended that you drink 65 to 80 ounces of water a day, every day, the week leading up to your ultrasound appointment.

3.     The position of the baby- It is ideal that your baby is head down (meaning the head is down low near your cervix). This is the position baby should be in before you go into labor. This position also yields the best 3D/4D imaging in the Ultrasound Test. The baby’s face should also be pointing upwards towards your stomach. If baby is looking towards your spine it would be impossible to get images. Babies in the breach position i.e. the gaping position are also harder to get images of, especially with an anterior placenta.

4.     The make and model of the Ultrasound Machine- Just like any other technology, the newer more modern devices and equipment produce better quality imaging. There are several major manufacturers of ultrasound machines. The leading brands offer the latest cutting-edge 3D/4D and high definition ultrasound technology. Ultrasound facilities that use newer, updated machines in the Ultrasound labs Delhi can provide you with better imaging of your baby.

5.     The experience of the sonographer- Learning to do ultrasounds is not an easy endeavor. Extensive professional training and several years of hands on practice is required to gain the experience necessary to acquire clear 3D/4D imaging. Additionally, the ultrasound tech should be knowledgeable about the tricks to get baby in the right position for photos. You’ll want to choose a facility that has an experienced tech who has performed, not just hundreds, but thousands of ultrasounds.
