If clear crystals appear in the urine, it is recommended to go to the hospital for relevant laboratory tests to clarify the specific cause. Because urine contains a variety of crystals and electrolytes, when the concentration level is normal, they dissolve in the urine and no crystals appear. However, when there is an excess of a certain component that causes saturation of the urine and precipitation of the related crystals, crystals in the urine can occur. Patients need to undergo urine-related tests and tests related to blood uric acid levels to find out if there is any crystal formation caused by the oversaturation of a certain substance. At the same time, patients should be asked if they have any symptoms of urinary sensitivity, such as frequent urination, urgent urination, painful urination, or if they have symptoms such as hematuria in the naked eye. If there is simply an increase in clear crystals without any urinary tract irritation symptoms, all that is needed is to drink more water and urinate more often. If there is high blood uric acid, you need to alkalize the urine and control uric acid intake in the diet or take oral medications that degrade uric acid to treat the symptoms.
