Kidney transplant surgery usually takes a long time. Like anywhere from 5 hours to ???
The reason for that, is because the function of kidneys is to ‘strain’ the blood, and take out all the impurities. Therefore, there are many blood vessels that have to be disconnected from the old kidney, and then carefully re-connnected to the new organ.
Pretty complicated stuff.

You mentioned you’re learning about diabetes. I just wanted to mention that not ALL diabetics need kidney transplants. If diabetes is well managed, it doesn’t always end up with organ failure. There are lots of ways to take care of the disease

If a complete cleansing is done, and the right diet followed, the body will rectify itself.

Have you already gone through the full kidney and colon cleansing processes?

Kidney cleanse is any procedure that involves drinking a huge amount of liquid, and taking care what you are eating. Just a better diet with more water can be enough! But, also any form of bowel cleansing will also help kidneys! The Master Cleanse Lemonade Diet is also a Kidney cleanse, juice fasting is also a kidney cleanse, and any other form of fasting that incorporates a lot of liquids, will in the same time clean a kidney. Do you need special herbs? Only if you have acute lower back pain, clear symptom of Kidney stones (sharp glass like crystals, made of phosphoric acid, or sometimes may include other acids). In special occasions, you can get a kidney stone crystallized in less then a few days !!! To melt a stone/stones, you may need a few weeks, or one day with the Watermelon Cleanse.

Herbal Kidney Cleanse Designed by Dr. Hulda Clark from her book "The Cure for All Disease", explains in detail how to cleanse the kidneys, and her cleansing program will get rid of most if not all the stones, WITHOUT surgery.
Ingredients:

1/2 cup dried Hydrangea root
1/2 cup Gravel root
1/2 cup Marshmallow root
4 bunches of fresh parsley
Goldenrod tincture (leave this out of the recipe if you are allergic to it)
Ginger Capsules
Uva Ursi capsules
Vegetable glycerine
Vitamin B6 250mg
Magnesium oxide 300mg or 1/4 cup Green Drink Beverage

Measure ¼ cup of each root and set them to soak, Together in 10 cups of cold tap water, using a non-metal container and a non-metal lid (a dinner plate will do). After four hours (or over night), bring liquid with soaked herbs to a boil and simmer for 20 minutes. Drink a ¼ cup as soon as it is cool enough. Pour the rest in through a bamboo or plastic strainer into a sterile pint jar (glass) and several freezable containers. Refrigerate the glass jar.
Find fresh parsley at a grocery store that does not spray its produce (ask the owner). Boil the fresh parsley, after rinsing, in 1 quart of water for 3 minutes. Strain out the liquid, then drink ¼ cup when cool enough. Refrigerate a pint and freeze 1 pint. Put the cooked parsley in your compost bucket.
Dose: each morning, pour together ¾ cup of the root mixture and ½ cup parsley water, filling a large mug. Add 20 drops of goldenrod tincture and 1 tbs. of glycerin.

Drink this mixture in divided doses throughout the day. Keep cold. Do not drink it all at once or you will get a stomach ache and feel pressure in the bladder. If your stomach is very sensitive, start on half this dose.

Save the roots after the first boiling, storing them in the freezer. After 13 days when your supply runs low, boil the same roots a second time, but add only 6 cups water and simmer only 10 minutes. This will last another 8 days, for a total of three weeks. You may cook the roots a third time if you wish, but the recipe gets less potent. If your problem is severe, only cook them twice.
After three weeks, repeat with fresh herbs. You need to do the kidney cleanse for six weeks to get good results, longer for severe problems.

Also take:

Ginger capsules: one with each meal (3/day).
Uva Ursi capsules: one with breakfast and two with supper
Vitamin B6 (250mg): one per day
Magnesium oxide (300mg): one a day

Take these supplements just before your meal to avoid burping.

Some notes on this recipe: this herbal tea, as well as the parsley, can easily spoil. Heat it to boiling every fourth day if it is being stored in the refrigerator; this resterilizes it. If you sterilize it in the morning you may take it to work without refrigerating it (use a glass container).

There are probably dozens of herbs that can dissolve kidney crystals and stones. If you can only find several of those in the recipe, make the recipe anyway; it will just take longer to get results. Remember that vitamin B6 and magnesium taken daily can prevent oxalate stones from forming. But only if you stop drinking regular tea and cocoa. Tea has 15.6 mg oxalate acid per cup. A tall glass of iced tea could give you over 20 mg oxalate acid. Switch to herb teas. Cocoa and chocolate, also, have too much oxalate acid to be used as beverages.

Remember too that phosphate crystals are made when you eat too much phosphate. Phosphate levels are high in meats, breads, cereals, pastas, and carbonated drinks, eat less of these, and increase your milk (2%), fruits and vegetables. Drink at least 2 pints of water per day.

You can dissolve all your kidney stones in 3 weeks, but make new ones in 3 days if you are drinking tea and cocoa and phosphate beverages.
Cleanse your kidneys at least twice a year.
