Patient discussions

Fluid intake should be at least 2.5 to 3 L per day for adults, and 1-2 L a day for children and young people (depending on age) to prevent stone formation.[15][16]​ In patients that are known stone formers, a target urine output of 2.0 to 2.5 L per day is recommended; intake volume may need to be even higher (up to 4 L per day).[17][18][19]​ Patients with nephrolithiasis should also be advised to follow a low-protein diet, and a low-sodium diet to prevent nephrolithiasis.[16][47]​​
