Abstract
Q 1: What are the differential diagnoses of milky / whitish urine and what tests can help in identifying the underlying cause? Answer: The most common cause of milky urine is the passage of chyle into urine, which develops as a result of communication between the lymphatic system and the urinary system [1]. Chyluria can be proven by ether test [2]. The chylous urine is mixed and shaken with an equal volume of chloroform and then it is centrifuged. Milky urine becomes clear with the extraction of fat globules in the chloroform layer, which is stained red on the addition of Sudan III. Additionally, similar to our child, one is likely to find low serum triglycerides but elevated urinary triglycerides in children with chyluria along with absence of fatty casts or renal tubular epithelial casts. The other causes of milky/turbid urine include pyuria due to urinary tract infection and crystalluria resulting from precipitation of phosphate in alkaline urine. Pyuria can be confirmed through urine microscopy by demonstrating the neutrophils in the urine (in contrast to the lymphocytes seen in chyluria) and phosphaturia is diagnosed by acidification of the urine with acetic acid, which dissolves the precipitated phosphate [3].
