Interventional radiology helped relieve this cat's ureteral obstruction by uroliths. In the first of new series for DVM Newsmagazinethis case-study approach to radiology is offered to showcase the many possibilities in managing medical cases through imaging. This case involves multiple uroliths obstructing a cat's ureter and kidney. Figure 1: A lateral radiograph of the patient in this case.

Note that the left kidney is larger than the right and that multiple stones are inside the left ureter and both renal pelves. Left ureteral obstruction secondary to ureterolithiasis with associated chronic kidney disease small right kidney and history of renal azotemia. Because of the sheer number of stones in this patient's ureter and kidney, traditional ureteral surgery was not considered the best option. Abdomminal

Serial ureterotomy procedures would be necessary, resulting in a high risk for stricture, leakage or reobstruction. Removal of all of the stones in the ureter would be impossible, making the chance for reobstruction high. Figure 3A: A retrograde ureteropyelogram obtained during the ureteral stent placement.

This was done via cystoscopy. A wire and catheter were advanced up the ureteral opening inside the urinary bladder, and then, using fluoroscopy contrast, the ureter was imaged by a retrograde Casw ureterogram. Notice the numerous stones and filling defects inside the ureteral lumen and the dilated and tortuous ureter and dilated renal pelvis. This was accomplished with a combination of cystoscopy, fluoroscopy and abdominal surgery.
