Ureters in cats have a small internal diameter (0.3-0.4mm), thus predisposing to intraluminal obstruction. Calcium oxalate uroliths are more commonly seen in middle-aged to older cats (Cannon et al., 2007). Upper urinary tract stones can be seen in cats of any breed. Calcium oxalate urolithiasis can be commonly seen in Persian, Himalayan, and Burmese breeds. Treatment options include medical management (MM), surgery, and interventional treatment (Adams et al., 2017). Medical management consists of fluid therapy, ureteral muscle relaxants (e.g., alpha-1 adrenergic antagonists such as prazosin), analgesia, diuretics (e.g., mannitol, furosemide), and corticosteroids (Lekcharoensuk et al., 2005). Surgical removal of ureteroliths is achieved by ureterotomy, ureteroneocystostomy, or pyelolithotomy and carries considerable risks. The exact procedure chosen depends on the location of the ureterolith (Hardie and Kyles, 2004). The most common postoperative complications are urine leakage and persistent ureteral obstruction after surgery. The present case report presents the diagnosis and management of ureteral calculi in a cat.Downloads
