Do worry about bladder rupture doing a cysto on one that large?


Hello, Jennifer,

On a bladder that large, I worry about it rupturing if I DON'T do the cystocentesis. I have been surprised about how resilient the organ is, though.

I remember a Pomeranian that we opened up in the process of relieving his obstruction with multiple calculi in the urethra and bladder. His bladder was so purple it was nearly black. I really thought it was necrotic and would just disintegrate, rather than healing, but he recovered well.

I also recall a cat whose bladder burst when I palpated it the first time on the exam table. I felt the baseball, then it disappeared. I cannot recall the outcome of the case, as to whether the owners let me proceed or decided to euthanize. I only remember the sickening feeling when the bladder burst.

In most cases, piercing the bladder with a 22-gauge needle is unlikely to cause any problems. It's not like popping a balloon.

This cat was super-great to work with. He didn't bother his catheter, started eating the next day, and was affectionate with staff, and even with ME.

Thanks for reading and writing.

My 10 year old male had this problem. I have to feed him C/D's. He pukes it up. I told my vet and he said keep giving it to him. Now my cat is constapated and had to go in for a "cleaning". Now I have to give a sugary liquid med to him twice a day by mouth. Any other suggestions on the food?


Hello, Nancy,

Dietary management can save your cat from being blocked again, and is well worth while. Most of my patients eat C/D without a problem.

Purina makes a prescription diet called UR that is formulated to address these problems.

Some feline specialists feel that you can substitute a high protein/low carbohydrate diet and achieve good results. If your cat cannot tolerate C/D, this might be a possibility.

If you choose this route, discuss it with your veterinarian and make arrangements to check the cat's urine specimen. You want to be sure that you are actually achieving that acid urine that you need, and that crystal are not forming, and that infections are not developing.

These foods are high protein, low carb (CHO = Carbohydrate)
