Story 4: Max's Story

Max is a 3 year old Ragdoll who came to the Hospital for Small Animals because he was not urinating and was lethargic for several days. He was diagnosed with obstruction of both ureters (that connect the kidneys to the bladder) due to stones that passed from the kidneys and became lodged in the ureters.

Because of this, his kidneys became distended and made him ill. He had surgery performed to relieve both obstructions. On one side, a ureteral stent was placed. This is a soft plastic double-pigtail catheter that has one curl in the kidney and the other in the bladder, allowing for urine to pass down into the bladder. In the other side, the ureter was too damaged to allow for a stent to be placed. In this side, a subcutaneous ureteral bypass device was placed.

Essentially, this creates a new ureter on that side with a port under the skin that allows for flushing and drainage of that kidney if necessary. To our knowledge, this is the first time this procedure has been performed in Scotland. Max recovered well from surgery and is urinating normally. Both kidneys are no longer obstructed and he is feeling much improved.

This radiograph of Max’s abdomen in ventrodorsal projection (on his back) shows both the ureteral stent with pigtails in the kidney and bladder (black arrows) and the subcutaneous ureteral bypass device (white arrow at the port of the device). There is also a drain in place for post-operative man
