My cat isn't peeing after bladder surgery. Can she recover from kidney failure?

Updated On September 23rd, 2025

Cat had bladder stone surgery and then would not eat, drink or pee afterwards. Took her back to vet due to dehydration and they said she was in acute renal failure so they put her on fluids right away and said they may need to keep her for several days - today they said she ate a little but did not do anything in the litter box yet. She gets very stressed out when not at home so I am extremely worried. Is there anything else I can do? Can she recover?

She can recover if the Kidney failure is due to her not being able to urinate. I would talk to your vet about placing a urinary catheter if they think she has any sediment that could be preventing her from urinating. If they think she is have spasms in her urethra (she is trying to pee but not much comes out), I have had good luck with prazosin. It helps to relax the urethral muscle. My biggest concern would be WHY she can't urinate. But it is great news and a great sign that she ate!!
