Cool case, did the dog go to surgery? Follow up? --Adrianne Fairbanks, DVM

These owners ultimately decided not to move forward with surgery, the dog was systemically ill and the outcome was euthanasia.

What was the radio opaque medium used for the patient study and the dose you would use? thank you

Hi Cindy! That's a fantastic question. There are different types of contrast media. For this we used iohexol (Omnipaque is one of the brand names). It is non-ionic contrast medium. It is lower in osmolality and less irritating than ionic contrast media. Although since it is technically not being filtered through the kidney, it would have been ok to use Hypaque. As far as the dose - there isn't a specific dose. The protocol is to aspirate the contents of the renal pelvis and then inject that same volume back in. Usually it is less than few mililiters depending on the size of the patient. And because the renal pelvis can dilate to a large degree, it is difficult to come up with a ml/kg dose that can be consistently used. I hope that answers your question!
