Hi,
The milky white urine is probably because of the renal failure which you are suffering from. Since the kidneys are not functioning, they are not able to acidify urine and this makes the urine alkaline and this causes the phosphate to precipitate in the urine making the urine milky white. You need to take care of the functioning of the kidneys with the help of your urologist and this will be rectified. I sincerely hope that helps. Take care.
