Dissolving Struvite Bladder Stones in an English Bulldog Without Surgery
by A reader
Yes, many struvite bladder stones can be dissolved without surgery. Veterinary consensus guidelines recommend trying to dissolve struvite stones first, unless a stone is blocking urine flow or the infection can't be controlled. Female dogs are less likely than males to get a stone stuck in the urethra, which is one reason dissolution is often a reasonable first try.
What vets usually do:
- Confirm the likely stone type with X-rays and a urine test, and send a urine culture before starting antibiotics.
- Feed a prescription struvite-dissolving diet only, with no other foods or treats, because extras can stop it working.
- Give antibiotics chosen by the culture for the whole time the stones are dissolving. In one study, dogs treated for infection were far more likely to dissolve their stones.
- Recheck with X-rays or ultrasound about every 4 weeks, and keep going for a few weeks after the last stone disappears.
Dissolution typically takes 1 to 2 months; in studies the median was about a month, and stones dissolved completely in about half to 6 in 10 dogs. If the stones haven't shrunk after 1 to 2 months, they probably aren't pure struvite, and removal is usually the next step.
One caution for Bulldogs: English Bulldogs are prone to urate and cystine stones, which don't dissolve on a struvite diet. That's why confirming the stone type matters, and why any stone that is removed should be sent for analysis. Minimally invasive removal methods are available at some referral centers if surgery is needed.
While she is on the diet, watch for straining with little or no urine, crying when peeing, vomiting or a painful belly. Those need a vet right away, because shrinking stones can occasionally move and cause a blockage.
