Design: Participants will be screened with: Medical and prior surgical history Review of existing MRI, x-ray, or CT scans Review of existing specimens and reports Pregnancy test for women of childbearing age CT or MRI: Participants will lie in a machine. The machine will take pictures of their body. Participants will have bladder surgery. This will occur in the same way as if they did not take part in this study.
