Cat Bladder Stone
Surgery Cost UK
Cat bladder stone surgery (cystotomy) costs £800 to £2,000 in the UK in 2026. Male cats with recurrent urinary blockages may need perineal urethrostomy (PU surgery) at £1,500 to £3,000.
What You Will Pay
Urinary problems are one of the most common and costly conditions in cats, particularly male cats. Bladder stones can cause painful urinary blockages that are a genuine veterinary emergency — a blocked cat can die within 24-48 hours without treatment. Understanding the costs and prevention options helps you prepare financially and protect your cat's health.

Factors That Affect
the Price
Type of surgery needed
Simple cystotomy (opening the bladder to remove stones) costs £800-£2,000. PU surgery (widening the urethra to prevent future blockages) is more complex at £1,500-£3,000. Emergency unblocking without surgery costs £300-£800.
Emergency vs elective
A blocked cat is a life-threatening emergency. Emergency treatment costs 50-100% more than planned surgery due to out-of-hours fees, intensive care, and longer hospitalisation. Male cats blocking on a weekend face the highest bills.
Duration of hospitalisation
Most cats stay 2-5 days after bladder surgery. Each day of hospitalisation costs £100-£250 for IV fluids, pain relief, monitoring, and nursing care. Complicated cases may stay longer.
Ongoing prevention costs
Post-surgery, cats typically need a prescription urinary diet (£30-£50/month) long-term to prevent recurrence. Regular urine monitoring (£30-£60 per test) is recommended every 3-6 months.
How to Save Money
Act fast on urinary symptoms
A cat straining to urinate, producing small amounts, or vocalising in the litter tray needs same-day vet attention. Early treatment of a partial blockage costs £200-£400. A full blockage with emergency hospitalisation costs £1,000-£3,000+.
Use prescription urinary diets
Prescription urinary diets (Royal Canin Urinary S/O, Hill's c/d) dissolve some stone types and prevent recurrence. At £30-£50/month they are far cheaper than repeat surgery. Buy online with a prescription for 20-30% savings.
Get stone analysis done
Stone analysis (£80-£150) identifies whether stones are struvite (can be dissolved with diet) or calcium oxalate (require surgery). This information prevents unnecessary surgery and guides long-term prevention.
Insure male cats from kitten age
Male cats are at much higher risk of urinary blockages due to their narrow urethra. Insurance taken out before any urinary issues will cover all future bladder treatment.
Would insurance have covered this?
On a typical lifetime policy an owner pays the excess (usually £60–£200) and, on some policies, 10–20% of the rest. Pre-existing conditions are never covered, so the time to compare is before something goes wrong.

Struvite stones can sometimes be dissolved with a prescription urinary diet over 4-8 weeks. Calcium oxalate stones cannot be dissolved and require surgical removal. Stone analysis determines the type and best treatment approach.
Yes, most policies cover urinary disease including bladder surgery, hospitalisation, and emergency treatment. Urinary claims are among the most common cat insurance claims, averaging £1,000-£2,000.
