Hi! Sam.
U don't say whether your Urotac was done with C-T scan, MRI scan or neither, ..........but will comment on your post anyway ;-)
Cortical cysts....no big deal....you can leave with them and are not likely to be anything to do with your UTI's. No treatment necessary as they are almost always , non-malignant (not cancer).
The suprarenal adenoma is interesting.......again not malignant (not cancer) and many people have them without them presenting any problems and again i doubt very much that the have anything to do with your problems.
Interesting report........but no big deal.
