What is Nephrocalcinosis in Children?

Nephrocalcinosis is the deposition of calcium salts within the renal parenchyma. The most common pediatric causes are prematurity with furosemide use, distal renal tubular acidosis, hyperoxaluria, and medullary sponge kidney.

It is detected easily on ultrasound and may progress to chronic kidney disease in advanced stages. Treatment of the underlying cause can slow progression.

Polyuria and polydipsia in renal tubular acidosis

Hematuria when nephrolithiasis coexists

Risk Factors
