The number of patients diagnosed
with kidney failure is increasing every day. A patient with kidney failure
undergoes dialysis to get a chance of living a productive life. Dialysis is
a procedure which substitutes many of the normal functions of a normal kidney.
Once a patient is diagnosed with kidney failure he/she has two options; to
either continue dialysis for the rest of their life or to undergo a kidney
A person choosing to undergo a
transplant has to go on the wait list, and one can never tell when the patient
will finally get the organ. The patient
either has to choose between regular hospital visits for the rest of his/her
life by undergoing dialysis or await for an organ donor to donate his organs.
Either option requires the patient to have a good financial background. A kidney
would also require the patient to have immunosuppressants
and medication during his entire life.
‘Technology along with medical treatment is improving every single day. In a couple of years, failed kidneys can be replaced by bionic ones.’
There is hope for patients, as
scientists have been working on a solution to kidney failure
. Dr. Shuvro Roy from University of
California, San Francisco and Dr. William H. Fissel from Vanderbilt University
Medical Center have invented the first ever bionic kidney. The function of the bionic kidney is that it can act as a replacement
for a kidney that has stopped functioning.
It is said that in two years time the World's first Bionic
Kidney would replace dialysis;
the added advantage is that it would have a
zero rejection factor. This is good news as it would be better than a donor's
kidney, as donor kidneys have rejections under certain circumstances. It is
said that the bionic kidney would be the size of a coffee cup, which consists
of numerous microchips which would be regulated by the heart. The procedure for
the bionic kidney to be placed inside the body is like a regular surgical
procedure. The function of the bionic kidney is similar to a normal kidney to
filter out all the toxins from the blood. It balances the levels of sodium and
potassium and regulates the blood pressure as well.
which is made by
is a process which is said to be similar to that of
microelectronics in computers. The device has about 15 microchips constructed
in layers. It has living renal cells which grow in and around the filters of
the microchip which in turn acts like a living kidney.
One of the main challenges of
this technique is to ensure there is no clotting while blood is being pushed
through the device. A constant check on
the device that there is no clotting or destruction of the device is guaranteed
by using fluid dynamics
which has been designed by Amanda Bucks, a
The National Institute of health
in 2015 funded this project with $6 million, which the scientists have tried to
put to full use. It is said that human
trails would commence only in 2018
due to current lack of funding.
There are a lot of benefits
associated with the bionic kidney, such as no immunosuppressants, low risk of
infection, continuous treatment, increased mobility, cost saving, and the
benefit of just a single surgery for lifelong blood connection with the device.
The public that are either
currently on dialysis or have a loved one in need of an organ are eagerly
waiting for this new invention to change their lives.
