Urinary Crystals

Canine Patient with Urinary Crystals

Case of the Month

The Patient

Lacie Meet Lacie, a sweet 2.5 year old Shih Tzu whose owner recently noticed blood in her urine. Aside from that concerning symptom, Lacie had been her usual self—normal appetite, thirst, and activity. She’s up to date on vaccines, and hasn't had any recent changes in diet or environment.


The Case

When Lacie came in on August 4th, Dr. Fish performed a thorough exam and diagnostic work-up. Her bladder ultrasound revealed hyperechoic (bright) fluid throughout the bladder, with a mildly thickened bladder wall. A urinalysis showed a pH of 8, red and white blood cells, struvite crystals, and bacteria. These findings pointed toward a urinary tract infection with crystal formation, which, if left untreated, could lead to bladder stones. An x-ray was performed to check for stones, and fortunately, none were found.

The Treatment Plan

Dr. Fish recommended a combination approach:

  •  Diet Change: Transition to Royal Canin Urinary SO, a prescription diet designed to dissolve struvite crystals and   prevent future ones.
  •  Medication: Carprofen for bladder inflammation and Clavamox for bacterial infection.
  •  Monitoring: The owner was instructed to watch for urinary accidents or blood in the urine.
  •  Recheck: Repeat bladder ultrasound and urinalysis in 3–4 weeks to monitor improvement and ensure crystals are   resolving.

The Outcome

Lacie went home the same day with her new diet and medications. While it’s too early to see final results, the prognosis is good. With prompt diagnosis, targeted treatment, and proactive monitoring, Lacie is on track for a healthy urinary system and a more comfortable bladder. We look forward to her follow-up visit and sharing the good news of her progress.
