Could my pet's surgery cause kidney failure? What are the risks?

Those lab tests look great! Yes, in some cases acute renal failure can be completely reversible with IV fluids and supportive care. This usually happens within a few days to a few weeks, so yes - this time frame would certainly fit. I'm very happy to see that things have improved so much for Tahnee! :)

In many cases of acute kidney injury, recovery is possible but not guaranteed. Intensive treatment is required to support her until her kidneys have a chance to recover and regular monitoring would be recommended to track any ongoing effects if she does recover

No, this is absolutely not correct to say that. kidney failure can be cause by various reasons but in most cases the exact reason is unknown. when kidney failure is already present, dry food and food with high protein levels can cause the kidney failure to get worse faster.

Hello. The presence of only 1 kidney is a birth defect that can occur. If that kidney is fully functioning, as demonstrated by normal blood kidney values, & a normal urinalysis, then there is no reason that anesthesia will be any more of a concern then for a cat with 2 kidneys. I am not sure what you mean by an indifferent colon, other than if there is one congenital birth defect, other defects are possible. We had a case of a puppy born with a deformed hind leg, & when he was old enough for neutering, also found a completely abnormal reproductive tract as well as a deformed kidney. This dog is now 13 years old & going strong. Your kitty may require periodic blood work to make sure the kidney stays healthy, & possibly some type of special diet depending on how the colon actually affects the kitten's overall well being. But, accidents in nature happen. Thanks for using Petco Pet Education Center, formerly Petcoach.

Some anesthetic drugs can alter sugar levels in blood but it is usually a very minor change which does not cause any real health issues. the main problem is with fasting the dog before surgery, which is an issue with dogs with diabetes. the solution is usually to limit the fasting to 6 hours only.

In my experience it is not common, although possible, to have seizures after anesthesia and surgery. However there are many diseases that can cause seizures. Many of them are unrelated to surgery and could be coincidentally be causing your dogs's seizures. Some medications are such as ketamine, acepromazine,and related compounds are known to contribute to seizure potential. It is possible, but fairly rare, that something related to the surgery, anesthesia, or medications precipitated the seizures. You should keep looking into these things with your vet and consider referal to a veterinary neurologist if you and/or your vet are still concerned.

It is not likely that there is a connection between her medications for the chronic kidney failure and the synovial sarcoma. Synovial sarcomas are very aggressive soft tissue tumors that tend to metastasize as well. Here is some good information: http://vetsurgicalcenter.com/synovialcellsarcoma.asp Unfortunately at 13 years tumors seem to be the most common cause of death in dogs. I am very sorry for your loss.
