You perform an abdominal ultrasound to evaluate a Yorkshire Terrier with a suspected liver shunt. After finding the shunt vessel, you complete the ultrasound and find several calculi in the bladder. What is the most likely type of stone? Cysteine Struvite Urate Xanthine - The correct answer is urate. Animals with portosystemic shunts are very predisposed to developing urate uroliths due to their inability to metabolize purines appropriately. A 2-year old male castrated Border Collie pres...
