Cystotomies

What is a Cystotomy?

A cystotomy is a procedure where the surgeon enters the urinary bladder. The removal of uroliths is by far the most common reason for doing this surgery, however a cystotomy can also be performed to address bladder tumours (benign), ectopic ureters and bladder tears.

Situational Awareness

This is a commonly performed procedure to remove bladder stones in small animal practice. The procedure itself is not considered to be highly difficult and the bladder is an organ that heals well. The greatest challenge tends to be ensuring that all of the stones are removed from the bladder and the urethra (especially from the male dog and cat).
A commonly reported complication is the recurrence of uroliths after a cystotomy. A study published in 2010 showed that stones were incompletely removed at surgery in 42% of the patients (JAVMA 2010:237(7):763-766). This workshop provides the information needed to get that complication rate down!

Pre-Surgical Considerations
  •  Take a radiograph of the abdomen which includes the entire lower urinary tract (avoid the catogram/dogogram).
  • A urinalysis for evidence of infection and type of crystals present.
  • Be prepared to harvest stones for analysis and mucosa for culture.
  • Pre-operative radiograph includes bladder and the entire urethra. Try to position the limbs so that the fabellae are not confused with uroliths.
  •  
What the client needs to know:
  • Dogs and cats with cystic calculi carry an excellent prognosis.
  • The prevention of future stone formation will likely need to be addressed with proper dietary management.

Key points for a successful cystotomy

Use stay sutures instead of tissue forceps to handle the bladder. This will minimize tissue trauma.
Once you have created your ventral midline cystotomy incision, enlarge it to facilitate removal of the stones
Before closing, evert the bladder and look for tiny stones within the mucosa and flush.
I like the 2 layer closure in the dog because it is fast, has few knots and the inversion helps to prevent adherence of the bladder to the midline abdominal incision. Cats tend to have a thick small bladder which is harder to invert so I close in 1 layer with a simple interrupted pattern.
Use a short lasting, preferably monofilament suture material for closing. Avoid PDS or other long lasting sutures as they can act as a nidus for stone formation as seen in the radiograph

Q & A

How long is the recovery from a cystotomy?

Most pets will recover quite quickly from this surgery, however, it is an abdominal surgery. The abdominal incision should be allowed to heal properly. This usually takes about 2 weeks.

What happens after a cystotomy?

The pet may have blood in its urine for a few days after surgery and he/she may feel the need to urinate frequently in the first 24-48 hours after surgery, even though the bladder is empty. Many will show no signs of having any urinary issues after the surgery. The appropriate diet will be recommended once the type of stone has been determined.
