Below is info I have saved on my computer and what has worked best for me.

Birds CAN be treated successfully, and live a long healthy life.
Renal problems are not exclusive to diet or genetics. A simple accident where the tiel get wedged somewhere with the wings up...even for a couple of minutes can cause a chill to the kidneys...thus crystallization of the urates, and if not caught soon enough, and the bird hydrated by Sub-Q fluids (means subcutaneous, fluids injected under the skin and absorbed by tisssues) it can go into renal failure and die.
Excess protein in the diet can contribute to to renal problems and failure. A breeder friend of mine added powdered protein to her hand-feeding formula to beef up her babies. Within 24 hours 11 out of 12 babies went into renal failure and died.
Pesticides or toxins can cause renal failure.
Symptoms to watch for that could indicate the bird is at risk of of renal failure: The bird acts lethagic. The muscles feel bunched and tight. The eyes are slitted from excruciating pain. There is either blood (pinkish discoloration) in the urine, or the urates will be thin, gritty, and chalky looking. Quick action of Sub-Q therapy can actually reverse the renal failure and save a bird.
The following helps with Gout and impaired Renal/Kidney function.
Initial treatment would be a medication called allopurinol. Usually you will see a dramatic improvement with the bird within a day.
Other helpful things are adding a small amount of cranberry or cherry juice to the drinking water. This helps to break down some of the crystals formed from the uric acid.
Hulled oats (oat groats) helps to reduce uric acid levels.
Celery greens and seeds are good for renal problems and act as an antiseptic to disinfect the urinary tubules. Celery is an excellent food that digests well with almost anything else. It contains the necessary mineral sodium, which is present in a ratio that can be easily accessed by the body. Sodium is critical, along with the mineral potassium, in managing the body's electrolyte balance. Electrolytes create electric osmotic pressure which helps the body to move fluids through the cell's membranes.
The silk from ear corn (organically grown or a herbal extract from a health food store) will sooth the damaged urinary tract, and improve urine flow. Plus corn silk is a source of potassium, Vitamin C and K.
Plain grass, roots and all (no joke, cats/dogs will eat this if they have urinary problems) will benefit both the liver and kidneys.
Dandilion greens helps with the liver, but it also aids the kidneys by stimulating them to remove toxins in the urine.
The above is a few simple things to help those with renal/kidney problems. I've personally used many of the above things to help the bird and not lose it.
