What does kidney lobulation mean?

What does kidney lobulation mean?

A lobulation is an appearance resembling lobules. For instance, the thyroid gland may become large and lobulated in Hashimoto’s thyroiditis. Fetal lobulation, also known as fetal lobation, of the kidney is evident on scanning. Fetal lobation is a normal stage in the development of the kidney.

Is a lobulated kidney bad?

Persistent fetal lobulation of kidney is a rare anatomic variant and can pose pitfalls in diagnostic imaging. It can mimic a renal neoplasm and sometimes even diagnosed on subsequent surgery and histology as a wrong radiological diagnosis.

What do the red and blue colors mean on a kidney ultrasound?

The colors on a kidney ultrasound represent the speed and flow direction of blood within a certain area (known as velocity flow). The mean velocity is then changed into a specific color. Flow toward the transducer is depicted in red, while flow away is shown in blue.

What is echogenicity of kidney?

Echogenicity, therefore, refers to how bright or dark something appears in the gray-scale image; the brighter something appears, the more echogenic it is. With regard to the kidney, echogenicity generally refers to how bright or dark the kidney parenchyma appears in comparison to the liver.

What is fetal lobulation of the kidneys?

Persistent fetal lobulation is a normal variant seen occasionally in adult kidneys. It occurs when there is incomplete fusion of the developing renal lobules. Embryologically, the kidneys originate as distinct lobules that fuse as they develop and grow.

What does Lobulated mean medically?

Medical Definition of lobulated : made up of, provided with, or divided into lobules a lobulated tumor.

What species has a lobulated kidney?

Although, kidneys naturally multipyramidal in their medullary morphology are rare in terrestrial mammals, kidneys with lobulated medullas do occur in: elephants, bears, rhinoceroses, bison, cattle, pigs, and the okapi.

What is most common indication for renal ultrasound?

Indications for renal ultrasonography include the following :

• Evaluation of cystic kidney disease.
• Diagnosis of hydronephrosis.
• Measurement of kidney size and echogenicity as part of an evaluation of chronic kidney disease.
• Detection of renal artery occlusive disease via Doppler images.

Is an echogenic kidney bad?

Echogenic kidneys were associated with medical renal disease in 94% of cases (30% glomerular, 48% tubulointerstitial, 16% end-stage) and with no detectable renal disease in 6% (three patients). Patterns of increased echogenicity and renal size were evaluated.

Is echogenic kidneys normal?

Echogenic kidneys can be a normal variant but are also seen in association with renal dysplasia, chromosomal abnormality, adult and fetal polycystic disease, Pearlman syndrome, Beckwith–Wiedemann syndrome, and CMV infection. The incidence of echogenic kidneys has been estimated at 1.6 cases per 1000 sonograms.

What happens if you get glomerular damage?

Glomerular disease damages the glomeruli, affecting their ability to properly function. Instead of keeping protein and red blood cells circulating in the blood, damaged glomeruli leak some of these products into your urine.
