– If your stuck on a raft etc. in a survival situation
in the middle of the ocean.
• Drinking your urine may keep you alive an
extra day or two.
– Urine is mostly water so it can replenish lost
water. 95%
– Sterile so it won’t give you disease.
– The other 5% is going back to your kidneys and
after a day or two this highly concentrated
waste can cause kidney failure.
– So your in trouble from total dehydration, or
complete kidney failure.
• Kidney Stone: A hard mass formed in the
kidneys, typically consisting of insoluble
calcium compounds.
• Kidney Stones: Cause severe stomach and
back aches that go down to the genitals and
last for a long period.
• Treatment
– Dietary Treatment (Changes)
– Pass the stone (if small)
– Surgery
– Shockwave Surgery
