NOTE: In all my guides, I start from a situation where a rehabilitator takes his responsibility to take care of the animals in an ethically correct way. You should always try to minimize stress for the bird and since the birds, just like humans, are not the same, it can mean that you handle a problem in different ways by being creative! If I see different ways of doing the same thing, I try to write it down in my guides, but it is always up to the rehabilitator to take their own responsibility.
I do not have to write “I recommend killing” or “contact a veterinarian” or “according to law, you should …” because I start from the situation where you do the best for the bird and that you as a rehabilitator have learned to draw the line so that you do not end up in an unwanted or illegal situation. There may be an eternal battle between what you want and what is best for the bird.
There are also many factors where a similar situation can give different results. For example: access to a veterinarian, lack of time, lack of knowledge and previous experience can include cause large differences in the treatment and decision-making process and indirectly also the end result. Knowledge of basic things can make a huge difference in the stress level of the crow. For example. avoid anything that is black or checkered. They do not like it instinctively and it creates stress when they see that you are dealing with something that is black.
I put energy into my guides to make it easier for a rehabilitator to find information and to spread knowledge.
Do you see a way to improve my guides or do you see a mistake or do you want to add something, feel free to inform me!
If you are worried about doing something because it is new, ask other rehabilitators or a veterinarian for help.
The guides are continuously updated, so make sure to always download the latest version from www.corvidlove.com

This guide describes what to do with birds that have contracted a kidney disease.

General:
Kidney disease can be seen at any age, but older birds are more likely to develop kidney failure . The causes are several and include glomerulonephropathy, renal tubular gout and chronic bacterial nephritis.

Diagnosis:
On physical examination, certain abnormalities may indicate kidney problems. Most birds with arthritis have some form of kidney disease. Unilateral lameness or paresis may also indicate compression of the lumbar / sacral plexus from an inflamed or enlarged kidney. Clinical signs include weight loss, depression, polyuria, polydipsia and dehydration. Diagnosis is made on the basis of persistent hyperuricemia before and after fluid therapy. Other laboratory findings may include anemia or increased CPK and urinary concentrations of gamma-glutamyltransferase. Imaging (X-rays or computed tomography) can show small or large kidneys with or without mineralization. Sometimes ureteroliths can be seen. Kidney biopsy is necessary for a definitive diagnosis.

Treatment:
Treatment includes supportive care (fluid therapy) and antimicrobials if necessary based on diagnosis. Colchicine (0.04 mg / kg, PO, 2 times a day) and allopurinol (10–30 mg / kg, PO, 2 times a day) have successfully reduced uric acid concentrations in certain disease processes. After the bird has stabilized, conversion to an appropriate diet and vitamin A supplementation, if warranted, should begin. Essential fatty acids at 0.22–0.44 ml / kg / day, PO, with low-dose aspirin (0.5–1.0 mg / kg, PO, every 12 hours) have been used anecdotally to manage kidney disease in birds .
