Gracie’s Bladder Stones

Six year old Gracie visited us in January for a cystotomy to remove stones from her urinary bladder. She was diagnosed at the Emergency Veterinary Service of Iowa City last month and had been receiving treatment through another veterinary clinic. After almost one month, she was still experiencing discomfort and passing bloody urine.

The development of bladder stones (also called uroliths) is not entirely understood, but seems to be related to the amount of certain types of minerals in the urine. These minerals combine to create crystals or stones. Some urinary stones can be dissolved using certain prescription diets designed for stone dissolution. The prevention of stones depends on which minerals are building up in the bladder. Gracie has a history of bladder stones; in 2014 she was diagnosed with ammonium urate stones, which are not very common in cats. These stones cannot be dissolved, so they were surgically removed at the time. Unfortunately, when she visited us in January, it was determined that another surgery was necessary.

Gracie is very fearful when outside of her home and becomes quite distressed with handling, so we sedated her in the bottom of her carrier by gently covering her with a thick towel and giving her an intramuscular injection of sedatives.

This is one low-stress technique we use for cats who do not tolerate handling when fearful.

Once sedated, a thorough exam was performed, blood was drawn for pre-surgical screening, and radiographs and an ultrasound of the bladder were obtained to give us a little more information.

The ultrasound image on the left shows a urine-filled bladder from a different cat with no stones present. The image on the right is the ultrasound of Gracie’s bladder. This is a small bladder filled with debris that appears light in color on ultrasound (black arrow).

After the blood-work was complete, Gracie was prepped for surgery and placed under gas anesthesia. The bladder was very thick and red, a sign of severe chronic inflammation. An incision was made in the bladder, and Dr. Hayes removed the stones and flushed out the bladder.

Surgery took about an hour, after which Vet Tech Katie used the therapy laser on the incision site. Laser therapy is standard at the clinic after every surgery and dental procedure to reduce inflammation and shorten healing time. Gracie then woke up from anesthesia with some warm towels in a quiet room.

Our surgery patients go home with 1 or 2 types of pain medication, depending on their overall health. A comfortable cat will recover more quickly than one that is still experiencing pain. Four days after surgery, Gracie was feeling okay but we were concerned about her appetite. After any procedure, we strongly encourage owners to stay in touch and let us know if their cat is not recovering well. We do expect that some cats will experience a few days of poor appetite or lethargy, but if that doesn’t resolve we want to determine what is causing the delayed recovery and find a solution as quickly as possible. In Gracie’s case, her obesity is a possible complication. Overweight and obese cats cannot be allowed to starve themselves for more than 2-3 days before we risk the slow development of hepatic lipidosis.

This image shows the stones extracted from Gracie’s bladder. You can imagine how much damage they do to a sensitive feline bladder over time. After the stones were removed, they were shipped to the University of Minnesota Urolith Center for analysis.

Treatment and preventative care to avoid future incidences will be determined once we know what type of stones were removed. We can’t assume that these stones are of the same type that developed in 2014.

How can bladder stones be prevented? The best preventative for potential urinary tract disease is to feed canned food. Dry diets are easy and convenient and there is nothing wrong with feeding some dry food, but cats generally don’t drink water until they are already dehydrated. Dehydration causes the body to retain water, which means very little urine is produced. Because the bladder doesn’t empty until it is full, urine can sit in the bladder for quite some time before it leaves the body. That stagnant urine can cause inflammation; crystals can form and stones may develop. We want to see the urine flushed out of the body frequently to prevent stone development. Canned food has a high moisture content to keep cats hydrated and keep urine moving.

-If your cat is restricted to a specific dry diet (like Royal Canin Hypoallergenic food), or simply doesn’t like canned food, you may try soaking the kibble in warm water before offering it.

-If both canned and dry options are available, you can also mix kibble into canned food, or sprinkle the dry kibble on top of canned food to encourage them to eat it.

-To encourage more frequent drinking, provide more than one source of water. Cats like their water and food offered in separate locations, with one bowl on each level of the house. Some cats prefer running water, and circulating water fountains are available.

-If your cat needs to eat canned food but refuses to do so, please contact us right away for a solution.

We will update this post when we learn what type of stones were recovered from Gracie’s bladder and we’ll let you know how she is doing as she recovers!

  1. Very impressed! Good job Natalie and Katie. Interesting and well written.
    Gracie is eating better (canned food now) and appears to be feeling better this morning. It has definitely been a stressful week for her, but I’m cautiously optimistic for her full recovery.
    THANKS to ALL of you @ the Cat Clinic for the professional and compassionate care you have given to Gracie and myself.
