The procedure in plain terms
A cystotomy is a surgical incision into the urinary bladder. The word simply means “opening the bladder.” It does not say why, which is why the same term covers stone removal, repair of a tear, biopsy, and removal of a bladder-wall mass.
In the vast majority of cases the reason is uroliths: bladder stones that have formed in the urine and now grind against the bladder lining every time the dog moves. Our bladder stone surgery service is built around that situation, and it is one of the most common abdominal surgeries we book for Talleyville dogs, particularly small breeds.
Step by step
Preparation. Urinalysis and culture identify any infection and the crystal type. Imaging shows how many stones there are and where they sit. Pre-anesthetic blood screening pays particular attention to kidney function, because a partially obstructed dog can arrive with raised values that change the anesthetic plan.
The abdominal approach. A midline incision exposes the bladder, which is then isolated with moistened swabs so urine and stones cannot contaminate the abdomen when it is opened.
The bladder incision. The bladder is opened on its underside, where the blood supply is least dense. That keeps bleeding low and gives clear access to the inside.
Stone retrieval. Every visible stone is removed, and the inside of the bladder is inspected and flushed to catch small fragments tucked into the folds of the lining.
Retrograde flushing. A urinary catheter is passed and sterile fluid is flushed backwards along the urethra, pushing any fragment lodged there back into the bladder for retrieval. This step is easy to skip and is the most common reason a dog needs a second operation within months. It is standard in every cystotomy we book.
Closure. The bladder wall is closed with fine absorbable suture in a pattern that keeps knots out of the bladder interior. Suture material exposed inside the bladder can act as a seed for a new stone, so the closure technique is a genuine prevention measure, not a technicality.
The surgery has two jobs.
Remove today’s stones, and make tomorrow’s less likely. Flushing and closure technique are the second job.
What happens to the stones
The retrieved stones are sent for analysis. It is optional, and it is the add-on we recommend most consistently, because the result shapes the entire prevention plan.
Struvite stones often form because of a urinary infection and frequently respond to a therapeutic diet plus treatment of that infection. Calcium oxalate uroliths do not dissolve and are prevented instead with a urine-diluting diet and high water intake. Those are completely different plans, and without analysis the recommendation is a guess.
Recovery in brief
Most dogs go home the same evening. Blood-tinged urine for three to five days is expected and should get lighter each day. Heavy bleeding, clots, or being unable to urinate needs an immediate call.
Keep water freely available and actively encourage drinking, since dilute urine is the simplest stone prevention there is. Activity is restricted for two weeks while the bladder wall and abdominal incision heal, and the complimentary healing evaluation at 10 to 14 days confirms everything has closed properly.
Non-stone cystotomy
The same surgical approach handles other bladder problems: repairing a tear after a road accident, taking a deep tissue biopsy of the bladder wall, or removing a benign bladder-wall mass. These start at $900 and follow the same safety and monitoring protocol.
If your dog is straining, passing small amounts often, or leaving blood in the urine, an assessment is the sensible next step. If surgery turns out not to be necessary, Talleyville Dog Surgery will tell you so.
