KIDNEYS AND THE HUMAN BODIES

Each human being is made up of billions of cells working 24 hours a day., producing toxic wastes which circualte through the blood. Causing it to become somewhat polluted. It would take very little time for the accumulation of these wastes to intoxicate the human body and death by poisoning could result. Fortunately, the kidneys are there to filter the blood-they remove toxins from the blood, eliminating them from the body in the form of urine. withoutkidneys, one would not survive the inevitable "blood pollution"

when kidneys stop functioning:

Various diseases can attact our kidneys, reduce their effectiveness and renal insufficiency would result. As the kidneys lose their filtering ability, the toxic waste accumilate in the blood and eventually when their lavel becomes sufficiently elevated, symptomps such as fatigue, lost of appetite and nausea appear. Ultimately, uremia, which is the accumulation of one of these wastes in the blood (urea), could kill.

• Preventing kidney failure
  It might take a while for symptomps to appear, that is when ore than 75% of the kidneys have ceased functioning. with the help of blood and urine test, kidneys failure may be detected before the appearance of symptomps. It is therefore possible to find the cause of renal insufficiency, perhaps correct it and threby save the kidneys. However, even if a cure i not possible, treatment can always be undertaken to minimize the progression of renal insufficiency. Diabetes and hypertension are the two major causes of renalinsufficiency which can be prevented by controlling these two problems with a proper diet and when neede, the appropriate medication.
• Treating Kidney failure
  Medical research has resulted in the discovery of techniques which can cleanse the blood of these toxins when the kidneys have completely ceased functioning, dialysis under the form of hemodialysis or peritonal dialysis. Thanks to this techniques, iremia does not kill anymore. However, the most satisfying solution still remains kidney transplants. unfortunately, the number of donors is not by any means sufficient to meet the even increasing need for kidneys.
  

KIDNEYS TRANSPLANT REQUIREMENTS

Kidney transplant requirements vary from program to program and country to country. Many programs place limits on age (e.g. the person must be less than 69 years old when put on the waiting list) and require that one must be in good health (aside from the kidney disease).
Significant cardiovascular disease, incurable terminal infectious diseases and cancer often are transplant exclusion criteria. In addition, candidates are typically screened to determine if they will be compliant with their medications, which is essential for survival of the transplant. People with mental illness and/or significant on-going substance abuse issues may be excluded.
HIV was at one point considered to be a complete contraindication to transplantation. There was fear that immunosuppressing someone with a depleted immune system would result in the progression of the disease. However, current research does not bear out this fear; in fact there are findings that immunosuppressive drugs and antiretrovirals may work synergistically to help both HIV viral loads/CD4 cell counts and prevent active rejection.
