Meet Ellie! She is a 6 yr, spayed female golden retriever we saw recently into the clinic for inappropriate urination and red/bloody urine. After running a urinalysis (testing the urine for bacteria, crystals, and pH changes), Ellie was sent home with antibiotics. Five days later, Ellie started having a decreased appetite and was still experiencing red urine, pain, straining while urinating, and licking at her v***a. We sent her home with an anti-inflammatory pain med, anti-nausea med, a more broad spectrum antibiotic, and a recheck scheduled in 2 days to make sure she was improving. When she returned for her recheck, she still had a decreased appetite and red/dark urine. At this point, it was time for radiographs (xrays). Upon seeing these two very large bladder stones on the top xray, Ellie was scheduled for surgery and the two bladder stones were successfully removed as pictured below. Ellie is now recovering well after her surgery at home with her family!
What are bladder stones?
Bladder stones are solid mineral deposits that form inside the bladder often due to pH or mineral content changes or increased concentration of the urine. These changes cause crystals to form and over time they combine and layer together to form bladder stones.
What are the common symptoms?
- Straining to urinate
- Urinating small amounts more frequently
- Dribbling urine
- Urinating inappropriately
- Vocalizing when urinating
- Licking the v***a/pen*s
- Urine with a strong odor, mucous, or blood present
How can I prevent bladder stones in my cat/dog?
Bladder stones are best prevented by feeding a urinary diet that focuses on maintaining pH and mineral content in the urine within normal ranges. Additionally, ensuring your pet has access to and drinks plenty of water dilutes the urine to decrease chances of bladder stones forming. In patients such as Ellie that have a history of bladder stones, it is recommended not to feed any treats/bones/flavored chew toys outside the urinary prescription diet from your veterinarian.
