Chyluria, also called chylous urine, is a medical condition involving the presence of chyle in the urine stream, which results in urine appearing milky white. The condition is usually classified as being either parasitic or non parasitic. It is a condition that is more prevalent among people of Africa and the Indian subcontinent. Chyluria appearance is irregular and intermittent. It may last several days, weeks or even months. There are several factors that trigger Chyluria recurrence. Chyluria is often caused by filariasis due to the parasite Wuchereria bancrofti, a thready nematode which lodges the lymph channels. The parasitic infection can lead to obstruction of peripheral lymphatic vessels and increased pressure within the vessels causing collateral flow of the lymph.
