This particular patient had bladder cancer and other problems, but an interesting report nonetheless: http://www.hindawi.com/crim/id/2012/953590/
Contains some interesting statements, such as: "It has been shown that this fungus can be detected in all main organs, especially in the brain or kidneys shortly after inoculation." And also "Infection in the kidneys, as contrasted to other organs, is not controlled."
Thanks for posting that article. The urinary tract is a common site for fungal candida. It may be rare that masses form there as the author notes, but it is a very common place for fungal candida to invade and establish itself in.
