<unk>  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, redirecting the lymph flow from the intestinal lymphatic vessels into the lymphatic vessels of the kidney and ureter. Because of obstruction, subsequent local inflammation of the area leads to dilation of the lymph vessels and the development of a urinary fistulae due to rupture of the lymphatic vessel, which allows for the passage of white blood cells, fat, and fat-soluble vitamins into the urine. Another cause of<unk>  is pregnancy or childbirth. In the United States, one of the most common causes is partial nephrectomy or thermal ablation of a kidney lesion.
