The kidney from a parts, Urinary System and are a gland in the back of the body cavity directly under the stomach, one on each side of the bottom line of the back. The left kidney is slightly higher than the right kidney and similar in form bean. Length of the total to about 10 cm.

Definition of kidney failure Kidney failure is also called renal failure. With kidney failure, the kidneys cannot get rid of the body’s extra fluid and waste. This can happen because of disease or damage from an injury.
2Types of kidney failure Acute failure Acute kidney failure is a sudden loss of kidney function that happens within hours or days. Causes may include: • Severe infections • Severe burns • Injury to or blockage of the blood flow to the kidneys • Low blood pressure
2Types of kidney failure Chronic failure Chronic kidney failure occurs when the kidneys slowly lose their function. It is a lifelong disease that does not get better. Causes may include: • Diseases such as diabetes, high blood pressure and heart disease • Kidney stones • Blockage or problems in the urinary tract
Causes of kidney failure Low blood pressure (hypotension). Muscle cramps.. Sleep problems.. Anemia.. Bone diseases. High blood pressure (hypertension).. Fluid overload.
Causes of kidney failure Inflammation of the membrane surrounding the heart (pericarditis. High potassium levels (hyperkalemia).. Infection.. Depression. Amyloidosis
Diagnosis of kidney failure Examine and enzymes college urea and creatinine. CBC ABG X-ray Excess fluid volume Imbalanced nutrition Urine studies US of kidneys
Definition of Dialysis Is a process that purify the body from harmful substances and excess fluid to his needs and which is supposed to come out with urine.
Types of dialysis There are two main types of dialysis: "peritoneal dialysis.“put into the abdomen Special fluid, called dialysate, is put into the abdomen through the catheter. The fluid stays in the abdomen for several hours. During this time, the body’s extra fluid and wastes move from the blood to the fluid. This fluid is much like urine and it is then drained from the body through the catheter..hemodialysis
hemodialysis Is a purification of the blood of toxins resulting from metabolic processes within the body and that does not rid the body than in the case Algosoralozivi to the kidneys.
Nursing care before hemodialysis .
Steps of hemodialysis process Blood circulates outside the body and passed through the dialyzer Comes into contact with a counter flow of dialysate solution Toxins are removed from the blood through diffusion Excess water is removed from the blood with a certain amount of filtration
Steps of hemodialysis process Blood is injected with heparin, an anticoagulant. Blood is then returned back to the body through the artery.
How Does Hemodialysis Work? A dialysis machine pumps small amounts of blood out of the body and through a filter called an artificial kidney or dialyzer. This kidney filters extra fluid and wastes from the blood. The blood is then pumped back into your body. Medicine will be given to you to prevent your blood from clotting.
How Does Hemodialysis Work? Fluid, called dialysate, is added to the dialysis machine to: • Help filter out extra fluid and wastes that have built up • Add chemicals that your body uses The dialysate is a mixture of water and chemicals that are present in your blood. This fluid can be adjusted, based on your lab values, to give you the best filtering with fewer side effects.
Complications Decline blood pressure Digestive problems Arteriosclerosis Anemia - Headache head - Fatigue and exhaustion and a sense of apathy after the dialysis. - A decline in the muscles of the legs. - A sense of vomiting. - Chest pain or back. - The high temperature. - Rarely, but may occur a loss of consciousness
