Description
Nephrolithiasis is a condition in which a hard mass (kidney stone) forms in the urinary tract. Low urinary volume, high urinary concentrations of crystal-forming substances (e.g. calcium, oxalate, phosphate, sodium and uric acid), low urinary concentrations of crystal-inhibiting substances (e.g. citrate and magnesium), and low urinary pH favour stone formation.
Dietary interventions are designed to alter the concentration of crystal-forming substances and/or crystal-inhibiting
