Excretory urography.

Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. In some instances, information regarding renal function and disease pathophysiology can also be obtained. With the recent advances in small animal ultrasonagraphy, excretory urography has become an underutilized procedure.

Placement of jejunal feeding tubes for post-gastric feeding.

In veterinary patients, postgastric feeding is indicated for uncontrollable gastric vomiting, gastroparesis, biliary tract disease, pancreatitis, and for patients at increased risk for aspirating secondary to decreased mentation, prolonged recumbency, or an unprotected airway. Postgastric feeding may be implemented via the placement of a jejunal feeding tube. These tubes can be placed surgically (jejunostomy tubes) or with fluoroscopic or endoscopic guidance.
