What is Kidney Failure?
Summary
TLDRKidney failure occurs when kidneys cease normal function, often due to infections or diseases, leading to the buildup of toxic waste in the blood. Treatment options include dialysis, which cleans the blood using a semi-permeable membrane and regulated fluid, or a kidney transplant offering a better quality of life. Maintaining a healthy lifestyle, including exercise, weight control, and avoiding harmful substances, can help prevent kidney issues.
Takeaways
- 🚨 Kidney failure occurs when kidneys can't function properly, possibly due to infections or underlying diseases.
- 🧪 Waste products like urea, creatinine, uric acid, and ammonium ions build up in the blood when kidneys fail, which can be toxic and fatal if untreated.
- 🩺 Treatment options for kidney failure include dialysis and kidney transplantation.

Q & A
What is kidney failure?
-Kidney failure occurs when one or both kidneys stop functioning normally, often due to infections, urine elimination issues, or underlying diseases, leading to the accumulation of toxic substances like urea, creatinine, uric acid, and ammonium ions in the blood.
Why is the accumulation of certain substances in the blood dangerous?
-The accumulation of substances such as urea, creatinine, uric acid, and ammonium ions is dangerous because they are toxic to the human system and can be fatal if not treated in time.
What are the available treatments for kidney failure?
-The treatments for kidney failure are dialysis and kidney transplantation. Dialysis helps to eliminate excess salts and nitrogenous wastes from the blood, while a transplant involves replacing a failed kidney with a healthy one.
What is dialysis and how does it work?
-Dialysis, also known as hemodialysis, is a procedure that cleans the blood by eliminating excess salts and nitrogenous wastes. During dialysis, the patient's blood is passed through a dialysis machine that contains a semi-permeable cellophane coil and sterile dialysis fluid, allowing small molecules to pass through and be removed.
What is the role of the cellophane coil in the dialysis machine?
-The cellophane coil in the dialysis machine is semi-permeable, allowing small molecules to pass through while preventing blood cells and large proteins from leaving. It provides a large surface area for material exchange between the patient's blood and the dialysis fluid.
How is the dialysis fluid maintained during the procedure?
-The dialysis fluid is changed regularly during the procedure to remove wastes and maintain a diffusion gradient between the patient’s blood and the dialysis fluid, ensuring effective waste removal.
What are the components of the dialysis machine?
-The dialysis machine consists of a steel tub with a filter filled with a warm fluid set at 37°C, a narrow tubular coil of cellophane with pores, and sterile dialysis fluid containing regulated amounts of dissolved salts and sugars.
Why is kidney transplantation considered a better option than lifelong dialysis?
-Kidney transplantation is associated with a better quality of life, lower risk of death, fewer dietary restrictions, and a lower cost of treatment compared to lifelong dialysis, as it replaces the failed kidney with a healthy one.
What are some lifestyle changes that can help maintain kidney health?
-To maintain kidney health, one should stay active, maintain a healthy weight, control sugar levels and blood pressure, avoid over-the-counter pills, refrain from smoking, and maintain a healthy fluid intake.
Are there any chances of a kidney healing once it has failed?
-Once a kidney fails, there are very rare chances of its healing, which is why dialysis or a kidney transplant is necessary to sustain life.
What is the purpose of the warm fluid in the dialysis machine?
-The warm fluid in the dialysis machine is set at 37°C to match the patient's body temperature, ensuring comfort and facilitating the exchange of substances between the blood and the dialysis fluid.
Outlines
🚑 Understanding Kidney Failure
Kidney failure is a critical health condition where kidneys lose their ability to function properly due to infections, urinary issues, or other diseases. This leads to the dangerous accumulation of waste substances like urea, creatinine, uric acid, and ammonium ions in the blood, which can be fatal if untreated. The available treatments are dialysis, which cleans the blood through a machine, or a kidney transplant, which replaces the failed kidney with a healthy one. Dialysis involves blood being passed through a semi-permeable cellophane coil to remove excess salts and wastes, while the dialysis fluid maintains a diffusion gradient for effective waste removal. A kidney transplant offers a better quality of life and has several advantages over lifelong dialysis.

Transcripts
What is Kidney Failure?
Kidney failure happens when one or both kidneys
stop functioning normally.
This could be due to infections,
urine elimination problems
or some underlying diseases.
Instead of being excreted,
wastes like urea,
creatinine,
uric acid
and ammonium ions remain in blood.
Accumulation of these substances
is toxic to the human system
and could prove to be fatal
if not treated in time.
The treatments currently available
are dialysis or a transplant.
Dialysis is also called haemodialysis.
It is a process or procedure
to eliminate excess salts
and nitrogenous wastes from blood.
It does not absorb or secrete anything.
During dialysis,
the patient's blood from the modified blood vessel in his arm
is passed into the dialysis machine
and returned after being cleaned.
The dialysis fluid is changed regularly
to remove wastes
and to maintain a diffusion gradient
between the patient’s blood and the dialysis fluid.
The dialysis machine contains the following parts:
a steel tub with a filter
filled with a warm fluid set at 37°C
to suit the patient's body temperature.
The machine also has a narrow tubular coil of cellophane
with pores and a sterile dialysis fluid.
The tubular coil of cellophane
is semi-permeable in nature.
It allows small molecules to pass through,
prevents blood cells and large proteins from leaving
and provides large surface area
for material exchange.
The sterile dialysis fluid
surrounds the cellophane tube
and contains regulated amounts of dissolved salts and sugars.
Once a kidney fails,
there are very rare chances of its healing,
hence this procedure has to be carried out
until the kidney is replaced with a new one.
Transplantation is a major operation
through which a failed or dysfunctional kidney
is replaced with a healthy one.
Kidney transplant is associated with better quality of life,
lower risk of death,
fewer dietary restrictions
and lower cost of treatment
compared to a lifetime on dialysis.
You can keep your kidney healthy
by keeping yourself active,
maintaining your weight,
controlling sugar level and blood pressure,
avoiding over the counter pills,
avoiding smoking
and also maintaining a healthy fluid intake.
