If white precipitates appear in a child’s urine, there are several possible causes to consider.
Uric acid salt precipitate. Concentrated acidic urine may precipitate urates when it cools, and is more common when it is cold and chilly.
Phosphate and carbonate deposits. If the urine is alkaline, phosphates and urates may precipitate, appear white and dissolve with the addition of acid, and carbonates may also produce bubbles when exposed to acid.
White deposits in the urine can also occur in the case of urinary tract infections. It may be mainly associated with bacterial multiplication in the form of pus urine and an increase in white blood cells resulting in milky white urine.
If a child develops white precipitates in the urine, it is recommended to visit a paediatrician at a regular general hospital for assessment of the condition, including routine urine tests, urine culture plus drug sensitivity tests and ultrasound of the urinary tract. If a urinary tract infection is diagnosed, it is recommended that the child be treated with sensitive antibiotics such as cephalosporins under the guidance of a physician based on the results of the urine culture. Care should be taken to allow the child to drink more water, urinate more often, avoid holding urine and pay attention to maintaining local hygiene.
