title: [Nephrocalcinosis].
abstract: Nephrocalcinosis is used to describe renal parenchymal calcification. Causes of nephrocalcinosis include persistent hypercalcemia, hypercalciuria, acid-base disorders, hyperoxaluria and urinary stasis. Patients with nephrocalcinosis initially present no symptom. However, advanced nephrocalcinosis is irreversible and causes impaired renal function. Therefore, careful observation for the presence and progression of nephrocalcinosis is necessary for patients who have risk factors for this disorder.
