Bladder Stone Surgery Cost in Dogs and Cats

Bladder stone surgery for a dog runs from about $587 to over $4,000 for a cystotomy, per cited CareCredit data. FurVerdict runs the math.

Reviewed June 1, 2026 by FurVerdict editorial · Methodology

Bladder stone removal surgery (a cystotomy) in a dog can start around $586.95 on the low end and run upwards of $4,000 on the high end, varying with location, the number of stones, the health of the bladder, and the sex of the dog, per CareCredit ^{[CareCredit: Bladder Stones in Dogs, 2026-09]}. The range is wide because the surgery itself is only part of the bill. This page covers what drives the cost and how insurance changes the math, not the procedure or the care.

The cost range

CareCredit puts the national average cost of surgical bladder stone treatment in dogs at $2,331 ^{[CareCredit: Veterinary Exam and Procedure Costs, 2026-09]}, with a cystotomy starting around $586.95 and running upwards of $4,000 at the high end ^{[CareCredit: Bladder Stones in Dogs, 2026-09]}. A straightforward case in a small dog sits near the bottom; a larger animal, an emergency presentation, or a blockage that needs urgent intervention pushes toward the top of the range. For cats, CareCredit lists emergency bladder stone surgery at an average of $2,096 ^{[CareCredit: Veterinary Exam and Procedure Costs, 2026-09]}, and feline urinary obstruction in particular can escalate quickly into emergency-priced care.

What's in the cystotomy bill

The surgery line is not the whole story. A cystotomy bill bundles the surgery with the pieces that surround it: imaging to locate and size the stones, pre-anesthetic bloodwork, anesthesia and monitoring, the surgery, and any hospitalization afterward. A recurrence, which bladder stones are prone to, means a second pass through that same band later. For insurance, what matters is that recurrence after a first treated episode is exactly where the pre-existing line starts to bite.

Why the price varies

Four cost drivers move this bill. Imaging is the first: stones have to be located and sized, which adds radiographs or ultrasound to the estimate. Anesthesia and monitoring are the second, scaling with the size of the animal and the length of the procedure. Whether the case is scheduled or an emergency is the third, since an obstruction that can't wait carries emergency pricing on top of the surgery. And hospitalization is the fourth: an animal that needs a day or two of inpatient monitoring after surgery adds a per-night charge to the total, which is what carries a complicated case toward the high end of the cited range, upwards of $4,000 ^{[CareCredit: Bladder Stones in Dogs, 2026-09]}.

What a policy would have covered

Bladder stones are an illness, so the surgery is a covered claim on an accident-and-illness policy, subject to the deductible, the reimbursement rate, the annual limit, and the illness waiting period. Run it against the cited range. On a $2,331 bladder stone surgery, CareCredit's national average for dogs ^{[CareCredit: Veterinary Exam and Procedure Costs, 2026-09]}, at an 80% reimbursement rate with a $500 annual deductible, the policy returns about 80% of the $1,831 above the deductible, roughly $1,465, leaving the owner near $866 ^{[ASPCA Pet Health Insurance: How Does Pet Insurance Work?, 2026-09]}. Against a $4,000 case under the same terms it returns about $2,800. The same 80% reimbursement on a $586.95 case, after the $500 deductible, returns about $70, because the deductible eats a larger share of a smaller bill.

The deciding term here is timing, in two directions. The first is the illness waiting period, commonly 14 days; a stone diagnosed inside that window is not a covered claim. The second, and the more expensive one, is recurrence.

The take

Bladder stone surgery in a dog is a bill that can start around $586.95 and run upwards of $4,000, with a $2,331 national average, and it is a covered illness claim on a policy bought before the diagnosis and past its illness waiting period. The catch is recurrence: a stone history on the record can make the next episode pre-existing and excluded, which is why the value of coverage here is almost entirely front-loaded to before the first event. If a policy is in place, weigh the reimbursement rate, deductible, and annual limit; if it is not, the cheaper exposure is a policy bought before any urinary sign enters the record.

How much does bladder stone surgery cost for a dog?

A cystotomy to remove bladder stones can start around $586.95 and run upwards of $4,000, per CareCredit, which puts the national average for surgical bladder stone treatment in dogs at $2,331. Location, the number of stones, the health of the bladder, and the sex of the dog move the price.

Does pet insurance cover bladder stone surgery?

Yes, as an illness claim on an accident-and-illness policy bought before the diagnosis and past the illness waiting period, subject to the deductible, reimbursement rate, and annual limit. A stone diagnosed during the waiting period, or a recurrence after a prior treated episode, can be excluded as pre-existing.

Why is bladder stone surgery so expensive?

The surgery line is only part of the bill. Imaging to locate and size the stones, pre-anesthetic bloodwork, anesthesia and monitoring, emergency pricing if the case can't wait, and post-surgery hospitalization all stack on top, which is what carries a complicated case toward the upwards-of-$4,000 end of the cited range.

Are recurring bladder stones covered by pet insurance?

Not reliably. Bladder stones recur, and once a treated episode is on the record, a later recurrence of the same condition can be treated as pre-existing and excluded at the reviewed carriers. The first episode is what a policy bought beforehand pays; a late buyer cannot insure the recurrence after the fact.
