There is a condition called Chyluria, which means that a person passes milky urine. The disease is cause by mosquitoes and it is generally filaria. This disease is more common in eastern UP and Bihar. It is not difficult to treat it. The diagnosis is done by chyle test of urine.
The problem with your query is that it is not clear whether you are passing milky urine or passing something white from vagina. If it is from vagina, it may be a fungal infection, which is again easy to treat. You can confirm this by sending the material for test for candida.
