cloudy urine in children

Many parents will find that their children have turbid urine. There are many reasons for this situation. It may be caused by the precipitation of urate, it may be caused by the precipitation of phosphate, or it may be caused by urinary tract infection. Parents need to pay special attention to this situation, understand the cause and then prescribe the right medicine. Here we will introduce why children's urine is turbid.

Reasons why children's urine is cloudy:

1. Urate precipitation: When concentrated acidic urine is cooled, light red urate may precipitate, which can be dissolved when heated or with the addition of alkali. This situation is more common in cold weather.

2. Phosphate and carbonate precipitation: If the urine is alkaline, phosphate or carbonate may precipitate in white color and can be dissolved by adding acid. Carbonates can produce bubbles when they come into contact with acids.

3. Urinary tract infection: It is mainly related to the reproduction of urinary tract bacteria, the appearance of pyuria and white blood cells. The urine is milky white.

4. Chylous urine: white chyluria, seen in obstruction of the perirenal lymphatic vessels caused by filariasis or other reasons. This is easy to identify with the naked eye.

Among the above four situations, the first two are generally not pathological conditions. If crystals of uric acid, phosphate, etc. are often found in fresh urine and are accompanied by a large number of red blood cells, the possibility of urinary stones should be suspected. During urinary tract infection, the urine becomes turbid, and pus cells or white blood cells may be found in microscopic examination of the urine sediment. As for patients with nephritis whose main symptom is protein in the urine, fresh urine is generally not turbid.
