What is Corticomedullary junction in kidney?

What is Corticomedullary junction in kidney?

The corticomedullary junction of the kidney is seen here, with the cortex in which can be seen a medullary ray (renal column) extending to the medulla, and the medulla.

What is in the Corticomedullary Junction?

An anatomical border exists between the cortex and medulla, which is called the corticomedullary junction where many inter- digitating reticular cells and macrophages harbor (40). In addition, there must be a kind of gate at the corticomeullary junc- tion through which only positively selected SP cells can pass.

What is loss of CMD in kidney?

Loss of CMD has been observed in renal insufficiency, secondary to a variety of etiologies, including glomerulonephritis, acute tubular necrosis, end-stage chronic renal failure, obstructive hydronephrosis, Fabry’s disease, and acute allograft rejection (1-8).

Where is the Corticomedullary junction in the brain?

The microhemorrhages were exclusively located at the gray/white matter interface (corticomedullary junction) of the frontal or temporal lobes.

What is Corticomedullary ratio?

The thickness of the two compartments in one individual is more or less equal, yielding a constant corticomedullary ratio of 1.0 with little variation (0.8-1.2). Normal CMR is maintained in the majority of acute and chronic renal diseases.

What is Corticomedullary differentiation?

Corticomedullary differentiation (CMD) abnormality (absent/reversed) is a parameter that can indicate possible nephropathy. The evolution of CMD across gestation had not been well established. Devrendt et al demonstrated the presence of CMD in all fetuses older then 20 weeks.

What is Corticomedullary osmotic gradient?

This rise in tissue osmolarity, the cortico-medullary osmotic gradient, is a consequence of the countercurrent multiplication along the loops of Henle driven by active NaCl retrieval across the water-impermeable ascending limb. The interstitial solutes are about half NaCl and half urea.

Is loss of CMD in kidney curable?

There is no cure for chronic kidney disease. The natural course of the disease is to progress until dialysis or transplant is required.

What is the meaning of Corticomedullary differentiation is lost?

Corticomedullary differentiation (CMD) abnormality (absent/reversed) is a parameter that can indicate possible nephropathy. The evolution of CMD across gestation had not been well established.

What is the function of the papilla in the kidney?

The papilla, or inner medulla, lies in the center of the adult kidney protruding into the pelvis. The collecting ducts pass through the papilla providing a conduit for the urinary filtrate to reach the ureter.

What does loss of corticomedullary differentiation in…?

Renal parenchyma is more echo genic and normal. loss of corticomedullary differentiation noted in both kindeys . in blood report creatinine is 2.0 mg/dl.i am 35 years old . can you please tell me what does this mean? Thanks for query .

What causes diminished corticomedullary differentiation in renal insufficiency?

In our subject population, loss of CMD with decreasing SKGFR can be attributed primarily to an increased T1 relaxation time of the cortex. Medullary T1 values vary but do not appear to correlate with degree of renal insufficiency. What causes diminished corticomedullary differentiation in renal insufficiency? J Magn Reson Imaging.

What is the skgfr value for corticomedullary differentiation?

Corticomedullary differentiation on T1-weighted images was assessed qualitatively and quantitatively. Results: SKGFR values ranged from 3.5 to 89.4 mL/minute based on radionuclide studies.

Why are pyramids more visible in acute cortical disorders?

In acute cortical disorders the pyramids may be more visible due to greater contrast between them and the increased cortical echo-genicity. In other cases there may be a decrease in corticomedullary differentiation.

What does corticomedullary differentiation mean in a kidney?

The cortex is the outer part and the medulla is the inner area. In a normal kidney, the cortex and medulla are distinctly visualised separately. In some kidney conditions, the cortico medullary differentiation is decreased and becomes less distinct and this can suggest a decreased kidney function or a medical renal disease.

When does the echogenicity of the cortex decrease?

Because of this, sonography depicts corticomedullary differentiation extremely well ( Fig 2 ). Postnatally, the echogenicity of the cortex gradually decreases, and it is usually hypoechoic relative to the liver by 4 months of age, but occasionally this process takes until 6 months.
