Urine salt crystals are large deposits of crystals in the urine that collect together to form urine salt crystals. If the urine salt crystals increase gradually, small stones will form, and further increase of stones may lead to fluid accumulation in the renal calyces or renal pelvis. For patients with urine salt crystals, it is recommended that you should drink more water, eat a light diet, and control the excessive intake of sodium and protein, so that the concentration of urine salt in the metabolites of the body is low. The most important purpose of drinking more water is that more urine can be formed, which can dilute the concentration of crystalline substances in the urine and can avoid further increase of urine salt crystals. It is recommended that patients should drink more than 2500ml of water per day.
