Urethral stones
Findings are Pro only. Every normal study is free; Pro opens each finding beside its normal.
See ProWhat to look for
- Mineral-opaque stones in the urethra at the os penis (yellow arrowhead, A)
- After retrograde flushing (B) they are gone; a catheter sits in the bladder
- Always include the whole urethra on a male dog's abdominal film
Against the normal
Read serosal detail first: fat lets you see the organs' edges, and losing it means fluid, no fat, or a crowd. Then size and place each organ against the vertebrae and the last rib, and follow the gas through the gut.

Read the film, then see the anatomy in 3D.
Vetomica puts every abdomen structure on this x-ray in a complete 3D dog you can peel, cut and X-ray from any angle, with every imaging finding beside its normal and practice at reading films.
The 3D animals are free every day up to a daily limit, no card. Imaging findings are Pro; every normal study stays free.
