@trishanna, your anxiety and disgust are understandable, and with those under wraps, a conversation with your urologist is called for — first to find out whether there was a link between the growth on your kidney and the pain and bleeding in your bladder. It’s hard to imagine how those symptoms might be related, so the doctor needs to focus on that when you talk to her/him. The second opinion should come from another urologist rather than a radiologist, who is not certified to deal with kidney diseases (only images from radiology).
Colleen Young has included a link to an earlier discussion of cysts on a kidney, and my own experience is featured in that discussion. If you can take a look at that, you’ll know better about where I am coming from based on my experience. Martin
