Question

In the case of renal failure and uraemia, which one of the following is employed?
A. Kidney replacement
B. Lithotripsy
C. Haemodialysis
D. Kidney removal

Answer 1

Kidney or renal failure is the term used to define a condition where the kidneys stop to work and cannot filter the waste from the blood. Uraemia is the condition when there is a large amount of waste in the blood. Both renal failure and uraemia are caused by the delayed and faulty functioning of the kidney.

Complete step by step answer: The normal kidney performs the function of filtering the waste from the blood and throwing it out by the urine.
The kidney damage leads to an increased amount of waste material accumulation in the blood and thus leading to life-threatening conditions.
Lithotripsy is a medical procedure used to remove the stones from the kidney. It uses shock waves to break the stones inside the body into small pieces and then these small pieces can be excreted while urination.
Kidney removal (nephrectomy) is a surgical process of removing the kidney to treat cancer or any other end-stage kidney disorder. It is also done on donors to remove the kidney for transplantation.
A kidney transplant occurs when there is no other option left with the patients suffering from end-stage kidney disease. The kidney can be transplanted from a donor or a deceased person.
As the waste material gets accumulated in the blood, the first kind of treatment for both renal failure and uraemia include the cleaning of the blood via dialysis or also known as haemodialysis.
Haemodialysis is a method of replacing the function of the kidney by a machine.
So, the correct answer is option (C).

Note: In the haemodialysis machine, the impure blood is pumped out of the body and passed into the dialysis machine where the blood is passed through various tiny tubes and the blood is cleaned by the process of osmosis. After this the pure blood is pumped back to the body.
