Cystotomy — surgical removal of bladder stones (uroliths) — is one of the most commonly performed soft tissue procedures in small animal practice. The surgery itself is straightforward and carries a low complication rate, with most dogs and cats recovering within 10–14 days. The challenge with bladder stones is not the surgery — it’s what comes after. PetMD notes that the most common long-term complication of cystotomy is stone recurrence, which occurs in approximately 40% of dogs. A mean time to recurrence of 335 days has been reported in case series data, meaning the average dog that recurs does so within about a year of the initial surgery. Post-operative follow-up that confirms surgical recovery and then establishes a prevention plan — stone analysis, dietary modification, hydration strategy, and monitoring schedule — is the difference between a resolved episode and a recurring surgical problem.
Why bladder stone follow-up has two distinct phases
Phase 1: Surgical recovery (days 1–14). Cystotomy recovery is generally smooth, but the first 2 weeks require monitoring for the standard post-abdominal-surgery risks — incision healing, urinary tract function, and confirmation that all stones were removed. Incomplete removal is a recognised complication: stone fragments left behind can act as seeds for rapid new stone formation, and some stones are not visible on pre-operative imaging. Post-operative imaging at 2–4 weeks to confirm complete stone removal is recommended for cases where this is a concern.
Phase 2: Recurrence prevention (weeks 2+). This is where most of the long-term value lies. Stone type — determined by laboratory analysis of the removed stones — dictates the prevention strategy. Struvite stones (most common in dogs with concurrent UTI) require infection management and dietary modification. Calcium oxalate stones (more common in cats and certain dog breeds) require increased water intake, dietary modification, and potentially prescription diets. Urate stones often have an underlying hepatic cause that needs investigation. Without stone analysis and a targeted prevention plan, the recurrence rate is high and the next cystotomy is a matter of when, not if.
The bladder stone removal follow-up timeline
| Timepoint | What to check | Red flags |
|---|---|---|
| 24–48 hours | Urinating normally — appropriate amounts, no straining, blood in urine reducing (some haematuria for 1–3 days post-cystotomy is expected), pain managed, eating | Not urinating at all or producing only drops — potential urethral obstruction or incomplete bladder healing; urgent review |
| Day 5–7 | Haematuria resolving, appetite normal, incision healing, activity restricted appropriately | Persistent haematuria beyond day 5, signs of urinary tract infection (straining, frequent small amounts), incision swelling |
| Day 10–14 | Suture removal recheck, full recovery confirmed, stone analysis results back | Signs of recurring UTI (commonly a precipitating cause of struvite stones) — culture and sensitivity needed |
| 4–6 weeks | Prevention plan in place — dietary change implemented, increased water intake achieved, prescription diet compliance | Owner has not started dietary modification, stone analysis results not acted on, signs of recurring lower urinary tract signs |
| Every 3–6 months (ongoing) | Urinalysis and imaging to check for early stone recurrence, dietary compliance, water intake | Early stone recurrence on imaging — prevention strategy needs revision |
What to ask owners after bladder stone removal
- Is [pet name] urinating normally — passing a reasonable stream, not straining?
- Has the blood in the urine reduced since coming home?
- Have you given all pain relief and antibiotics as prescribed?
- How does the incision look — any swelling, redness, or discharge?
- Is [pet name] eating and drinking normally?
- Have the stone analysis results been discussed with you, and do you understand what type of stones were found?
- Have you started the dietary changes or prescription diet recommended based on the stone type?
- Have you been increasing [pet name]‘s water intake — wet food, a water fountain, or additional water bowls?
- Do you have a follow-up urinalysis booked at the 4–6 week mark?
- Do you know the signs to watch for that would indicate the stones are recurring?
Common bladder stone follow-up mistakes clinics make
Not following up on stone analysis results with the owner. Stone analysis results typically take 1–2 weeks and arrive after the pet has left the clinic. The owner needs to be contacted when results are available and receive a specific prevention plan based on stone type. This is frequently not done — the results arrive, are filed in the record, and the prevention plan is never initiated. A follow-up call specifically timed to when stone results are expected closes this gap.
Underestimating the water intake conversation. Dilute urine is the single most effective preventive measure across all bladder stone types. Owners who understand this and actively increase water intake — through wet food, water fountains, multiple bowl locations, or broth additives — significantly reduce recurrence risk. This conversation happens once at discharge and is then never revisited. A follow-up call at 4–6 weeks that asks specifically about water intake strategy reinforces it at exactly the right time.
Not scheduling monitoring imaging. The ACVIM recommends surveillance imaging (radiographs or ultrasound) at 3–6 months post-cystotomy to detect early stone recurrence before stones become large enough to require repeat surgery. Most owners are not aware this is recommended, and most clinics don’t proactively schedule it. A follow-up reminder at the 3-month mark significantly improves compliance with this recommendation.
How to automate bladder stone follow-up without adding to your team’s workload
Nidana Loop schedules a 24-hour call post-cystotomy and a day 10–14 follow-up. A 4–6 week call specifically addresses stone analysis results and prevention plan compliance. For dogs with confirmed high-recurrence stone types (calcium oxalate, urate), Loop can schedule 3-monthly monitoring reminders automatically. The clinic sees summaries and flags for any case where urinary signs are returning.
