Renal Replacement Therapy

by Carol Gomes

The renal replacement therapy, or RRT, is a method required for patient to undergo when his/her kidneys are working at way below than 10% to 15%. This type of procedure can be accomplished in any of the following process:


Patients who have advance chronic renal failure, or CRF, who already have reached the end-stage renal disease, or ESRD, usually need to undergo the dialysis. The chronic renal failure is when the kidney constantly inhibits its function leading to a progressive loss for a certain period of time. Patients who have this kind of condition are recommended to be prepared before the matter of dialysis need, instead of counting on it in the time of severe condition.

The required method of dialysis is signified from various conclusions in the analysis of blood, like the high creatinine level and the elevations of nitrogen, and through a glomerular filtration that is, most of the time, 15 and often less than 10. The inflammation of the sac which surrounds the area of the heart, or pericarditis, is related with the case of end-stage renal disease, or ESRD, and denotes the need for the process of dialysis.

The two types of dialysis are:

  1. Hemodialysis – a method that removes the excess quantity of waste and fluid found in the kidney when they are not able to do it properly. The blood is extracted intravenously, and then sent to a machine called a dialyzer, and then is sent back to the body through the blood vessel. Within the dialyzer, the blood is transported over a membrane for filtration of waste and fluid and into the dialysate solution. The dialysate is afterward pumped out into a disposal container and the new dialysate is pumped in. This process of the taking away the excess fluid is called ultrafiltration.
  2. Peritoneal dialysis – this method cleans the blood without the process of being removed. Dialysate is injected to the peritoneal space located in the abdomen through the use of a two-way catheter. The membrane that is tasked to line the abdomen permits the waste and fluid to transport the blood into the dialysate, which is then pumped out. This method of peritoneal dialysis is made up components of salt and sugar and supports the ultrafiltration throughout the peritoneum.

Kidney transplant

The kidney transplant operation is a recommended process for those patients who are under the end-stage renal disease, or ESRD. This process involves the replacement of the kidney or kidneys that have failed to provide functionality. A healthy kidney is transferred into a patient who has been suffering of kidney failure. The donor and the transplant recipient can work with only one kidney and neither of them needs the process of dialysis after the kidney transplant.
