What is the technique for performing an ultrasound of the kidneys and ureters in cats?

The abdomen should be shaved from the xiphoid process to the pelvis and on both sides of the rib cage.
The patient can be positioned in dorsal or lateral decubitus.
The kidneys in cats are less globular and mobile than in dogs.
Convex medium frequency probes provide a better resolution and detail than high frequency linear probes.
The Doppler technique is not necessary for the evaluation of renal pathologies in cats.
