PURPOSE Nephrocalcinosis is commonly present in primary hyperparathyroidism, distal renal tubular acidosis and medullary sponge kidney disease. To our knowledge it has not been studied in patients with calcium phosphate stones who do not have systemic disease. MATERIALS AND METHODS We studied patients undergoing percutaneous nephrolithotomy who had calcium phosphate or calcium oxalate stones ...

Nephrolithiasis and nephrocalcinosis are common in both term and premature infants who have had difficult neonatal courses.  Multiple factors may contribute and being born from a diabetic mother  Is one of them. This case is about a neonate with nephrocalcinosis .she is followed to 9months and remained healthy during a 9 month follow up.

OBJECTIVE X-linked hypophosphatemia (XLH) is characterized clinically by rickets, hypophosphatemia, and hyperphosphaturia. Conventional treatment of XLH with oral phosphate and vitamin D is associated with increased urinary calcium excretion and nephrocalcinosis. Thiazide diuretics decrease urinary calcium excretion. The objective of this study was to determine the effect of thiazide diuretics ...

Diets containing alkali-treated soy protein have been shown to cause nephrocalcinosis in rats. In order to determine if alkali-treated soy protein is the dietary component that induces nephrocalcinosis, the effects of a purified diet containing 20% alpha-protein (an alkali-treated soy protein) were compared with the effects of the same diet containing 20% promine-D (a non-alkali-treated soy pro...

Many in vitro and in vivo studies on the mechanisms underlying calcium nephrolithiasis have provided evidence of a frequently associated condition, i.e., a microscopic renal crys‐ tal deposition that can occur within the tubular lumen (intratubular nephrocalcinosis) or in the interstitium (interstitial nephrocalcinosis). Medullary nephrocalcinosis is the typi‐ cal pattern seen in 98% of cases o...

OBJECTIVE Cystic fibrosis (CF) is characterized by chronic pulmonary disease, insufficient pancreatic and digestive function, and abnormal sweat concentration. There is controversy about predisposing factors of nephrolithiasis and nephrocalcinosis in patients with cystic fibrosis. We assessed the results of metabolic evaluation in patients with cystic fibrosis and its correlation with nephrocal...

Stone formation and nephrocalcinosis are both very common features of primary hyperoxaluria, yet the extent of each disease varies markedly between patients. Here we studied whether kidney damage from nephrocalcinosis and/or stone related events contributed to end-stage kidney disease (ESKD). Clinical information was analyzed from 348 patients enrolled in the Rare Kidney Stone Consortium Primar...

The effects of parathyroidectomy (PTX) on the development of nephrocalcinosis in rats fed a diet containing alpha protein were investigated for the purpose of determining whether the nephrocalcinosis was phosphate-induced. PTX completely prevented the occurrence of nephrocalcinosis in rats fed a phosphate-supplemented commercial laboratory diet for 4 weeks. However, PTX did not completely preve...
