Sarcoid nephrocalcinotic renal failure reversed by sodium cellulose phosphate

A case of renal failure due to sarcoidosis with hypercalciuria and nephrocalcinosis is described. Prolonged treatment with inorganic absorbable phosphate significantly deteriorated the patient's renal function. After a sodium cellulose phosphate treatment, renal failure was completely reversed. We suggest that sodium cellulose phosphate is the treatment of choice in sarcoidotic renal failure induced by nephrocalcinosis.
