Renal failure, is the term that is used to detail a situation in which already do not work properly the kidneys. There are several methods doctors used to arrive at a successful diagnosis and determine the treatment to be followed.
There is a great diversity in treatments for renal failure and depends on some factors underlying disease, in some cases hospitalization is necessary.
Treatment can be focused on the causes of the failure renal or looking for a substitute for kidney function, through urethras, dialysis or nephrostomy.
¿What consists the Renal Failure?
One of the roles played by the kidneys in the body is the keep of the electrolyte fluid balance, eliminate toxins and remove waste from the blood. The means by which perform this function is urine.
Another important function carried out the kidneys is the production of red blood cells in the bone marrow and give strength to the bone structure of the body.
The term renal failure refers to the inability of the kidneys to perform functions described effectively.
When there is an accumulation of toxic waste in the blood occurs when a chemical imbalance in the blood, which can be very serious if not treated.
Over time, patients with kidney failure can develop a below-normal red blood count, and weaken bones.
The cause of chronic kidney disease can be caused by various diseases, one of them, diabetes which with the passage of time can cause renal failure.
There are other health conditions that can cause kidney failure, for example: decreased blood flow to the kidneys, obstruction of the urethra, infections that they left damage, some medicines, and contrast materials used when x ray images are taken.
Renal failure can be triggered quickly and may be permanent damage to the kidneys.
Diagnosis of Renal Failure
There are a variety of causes that can trigger kidney failure, when you visit the doctor and after a clinical trial can be determined which is the cause and based on that, it can be determined which studies will be performed to verify, in order to get the diagnosis of kidney failure the doctor may order any of the following studies:
1.- Renal ultrasound
It’s images for which the high-frequency sound waves that allow to visualize the kidneys in vivo is used and is usually the first test that is requested to check the kidneys function.
A CT scan, is the combination of X-ray device in conjunction with a computerized system that produce multiple images of the inside of the body, the test is frequently used to have a much broader vision of the causes that may be provoking kidney failure.
3.- Urography CT
It is used for patients that present blood in the urine, through this study patients who have infections of the urinary tract get diagnosed, likewise for patients with cancer in the urinary system.
This study use a magnetic field and radio frequency which help to produce very detailed images of the kidneys.
It is a test where the kidneys are evaluated using nuclear medicine with a gamma camera, detailing the function of both kidneys.
We speak of extraction which is guided by images of a fragment of kidney tissue to physical examination, this test is usually the last option for the diagnosis.
Treatment for kidney failure
As we have said before, to treat renal failure it must first see the cause that provoke it, but in the vast majority of the cases required hospitalization.
There are two types of treatment…
a) Treatment on the cause of the renal failure
b) renal function replacement: Nephrostomy where is the insertion of a small tube or stent that is connected to an external drain bag, what you try to do is unlock the ureters and thus normalize the flow of urine from the kidneys, provides it has been demonstrated that this is the cause.
Dialysis and hemodialysis: both processes have the function of removing toxic wastes and excess fluids, becoming substitutes for renal function. Now though, kidney transplantation is the most complete and effective way to replace renal function, but it is not always the most appropriate for certain patients.
c) Today talks about regenerative medicine as a treatment for kidney failure. It is said that the kidney has the ability to regenerate itself through the tubular epithelial cells, which is what happens in part when there are acute renal failure, however, in chronic kidney disease, the kidneys do not possess this capability being necessary the complete development of a new kidney.
Get a regenerated kidney is possible provided that the techniques applied gets achieve a very accurate structure of the kidney, urine should be produced and it must grow with or without minimal immunosuppression.
It is important to mention that the two most common causes of kidney disease are hypertension and diabetes, if you have any of these diseases must be kept under medical surveillance, because to be well controlled, favorably decreases the possibilities develop kidney disease.
We should change our thinking and try to prevent before cure, we can’t wait for the symptoms of kidney failure because we could not have too much time to recover.
Remember that symptoms tend to be more subtle and when they appear is because the disease is advanced, not stop going to the doctor is of vital importance.
Perform check-ups preventive speaks of how much you’re interested your health and that of your loved ones.
