What is the difference between medullary sponge kidney and medullary nephrocalcinosis?

5 The primary difference between MSK and medullary nephrocalcinosis is that MSK is dilation of the collecting ducts of Bellini, whereas medul- lary nephrocalcinosis is calcium deposits or kidney stones within the dilated collecting ducts.

What is a major symptom of medullary sponge kidney?

The first symptoms of Medullary Sponge Kidney typically blood in the urine, stone formation or signs of a urinary infection such as excessive urination (polyuria) and/or burning and pain while urinating. In some affected individuals, calcium stones may form in the kidneys (nephrolithiasis).

What is medullary calcinosis?

Medullary nephrocalcinosis is the diffuse calcification of the renal medulla due to deposition of calcium salts within the parenchyma.

Is MSK hereditary?

In addition, medullary sponge kidney has been identified in 12-20% of patients who form calcium stones.

Is RTA life threatening?

Frequently, patients present with minimal or no symptoms, which can lead to a delay in diagnosis. Progressively, it can lead to marked acid-base abnormalities, including hyperchloremic metabolic acidosis and severe hypokalemia, which can be fatal.

What is a spongy kidney?

Medullary sponge kidney (MSK) is a congenital disorder that can affect one or both kidneys, or only part of one kidney.
