The first photo is testicles in close proximity to kidney. The second is the colon connected to a ureter. The Phillips was to distinguish where each exit was located (same spot). His urine was backing up into his colon. So essentially, where it was connected to his ureter, is where some of his urine would go, and his stool would exit to his bladder AND urine would backup into his colon. The exit to outside of his body was no bigger than a pencil lead. The vet thinks this was just a random anomaly. She has only seen 2 in her career and this little guy was the more extensive of the two, although she said she hadn't dissected the other, only euthanized him.
