The urine contains more lymphatic fluid and is whitish in color, accompanied by chronic superficial lymphadenitis or bilateral lower limb edema. 2. Salt urine, often seen as a result of increased salt content in the urine, and therefore precipitates white crystals. When urinating, it can be seen as whitish or slightly cloudy and is usually not accompanied by any urinary tract irritation symptoms.

It is necessary to conduct urine related examination and drink more water and urinate more appropriately.3. When purulent urinary tract infection occurs, such as renal abscess, pyelonephritis, etc., the urine contains more pus, accompanied by cloudy urine, and accompanied by symptoms such as urinary frequency, urinary urgency and painful urination, it is necessary to conduct routine urine examination and urine culture examination to confirm the diagnosis.
