Chronic Renal Failure Overview
Chronic renal failure is a slowly worsening loss of the ability of the kidneys to remove wastes, concentrate urine, and conserve electrolytes.
NYTimes Friday, March 6, 2009
Reference from A.D.A.M.
Unlike acute renal failure, chronic renal failure slowly gets worse. It most often results from any disease that causes gradual loss of kidney function. It can range from mild dysfunction to severe kidney failure. The disease may lead to end-stage renal disease (ESRD).
Chronic renal failure usually occurs over a number of years as the internal structures of the kidney are slowly damaged. In the early stages, there may be no symptoms. In fact, progression may be so slow that symptoms do not occur until kidney function is less than one-tenth of normal.
Chronic renal failure and ESRD affect more than 2 out of 1,000 people in the United States. Diabetes and high blood pressure are the two most common causes and account for most cases. Other major causes include:
* Alport syndrome
* Analgesic nephropathy
* Glomerulonephritis of any type (one of the most common causes)
* Kidney stones and infection
* Obstructive uropathy
* Polycystic kidney disease
* Reflux nephropathy
Chronic renal failure results in an accumulation of fluid and waste products in the body, leading to a build up of nitrogen waste products in the blood (azotemia) and general ill health. Most body systems are affected by chronic renal failure.
Back to TopSymptoms
Initial symptoms may include the following:
* Fatigue
* Frequent hiccups
* General ill feeling
* Generalized itching (pruritus)
* Headache
* Nausea, vomiting
* Unintentional weight loss
Later symptoms may include the following:
* Blood in the vomit or in stools
* Decreased alertness, including drowsiness,confusion, delirium, orcoma
* Decreased sensation in the hands, feet, or other areas
* Easy bruising or bleeding
* Increased or decreased urine output
* Muscle twitching or cramps
* Seizures
* White crystals in and on the skin (uremic frost)
Additional symptoms that may be associated with this disease:
* Abnormally dark or light skin
* Agitation
* Breath odor
* Excessive nighttime urination
* Excessive thirst
* High blood pressure
* Loss of appetite
* Nail abnormalities
* Paleness
Back to TopExams and Tests
There may be mild to severe high blood pressure. A neurologic examination may show polyneuropathy. Abnormal heart or lung sounds may be heard with a stethoscope.
A urinalysis may show protein or other abnormalities. An abnormal urinalysis may occur 6 months to 10 or more years before symptoms appear.
* Creatinine levels progressively increase.
* BUN is progressively increased.
* Creatinine clearance progressively decreases.
* Potassium test may show elevated levels.
* Arterial blood gas and blood chemistry analysis may show metabolic acidosis.
Signs of chronic renal failure, including both kidneys being smaller than normal, may be seen on:
* Abdominal CT scan
* Abdominal MRI
* Abdominal ultrasound
* X-rays of the kidneys and abdomen
This disease may also alter the results of the following tests:
* Erythropoietin
* PTH
* Renal scan
* Serum magnesium - test
* Urinary casts
Back to TopTreatment
The goal of treatment is to control symptoms, reduce complications, and slow the progression of the disease.
Diseases that cause or result from chronic kidney failure must be controlled and treated as appropriate.
Blood transfusions or medications such as iron and erythropoietin supplements may be needed to control anemia.
Fluids may be restricted, often to an amount equal to the volume of urine produced. Restricting the amount of protein in the diet may slow the build up of wastes in the blood and control associated symptoms such as nausea and vomiting.
Salt, potassium, phosphorus, and other electrolytes may be restricted.
Dialysis or kidney transplant may eventually be needed.

Back to TopOutlook (Prognosis)
There is no cure for chronic renal failure. Untreated, it usually progresses to end-stage renal disease. Lifelong treatment may control the symptoms of chronic renal failure.
Back to TopPossible Complications
* Anemia
* Cardiac tamponade
* Changes in blood sugar metabolism
* Congestive heart failure
* Decreased functioning of white blood cells
* Decreased immune response
* Decreased libido, impotence
* Dementia
* Electrolyte abnormalities including hyperkalemia
* Encephalopathy
* End-stage renal disease
* Fractures
* Hemorrhage
* High blood pressure
* Increased infections
* Joint disorders
* Liver inflammation (hepatitis B or hepatitis C)
* Liver failure
* Loss of blood from the gastrointestinal tract
* Menstrual irregularities,mscarriage, infertility
* Nerve damage
* Pericarditis
* Peripheral neuropathy
* Platelet dysfunction
* Ulcers
* Seizures
* Skin dryness, itching /scratching with resultant skin infection
* Weakening of the bones
Back to TopWhen to Contact a Medical Professional
Call your health care provider if nausea or vomiting persists for more than 2 weeks.
Call your health care provider if decreased urine output or other symptoms of chronic renal failure occur.
Back to TopPrevention
Treatment of the underlying disorders may help prevent or delay development of chronic renal failure. Diabetics should control blood sugar and blood pressure closely and should refrain from smoking.

Hi Carol:
I'm the sauna guy Billybill.
Your post mentioned (uremic frost) which is caused because the sweat of people with impaired kidneys is filled with a lot more waste than people
with fully functional kidneys. That means the as the kidney declines the sweat glands in skin take over for the kidneys. That means taking a long sauna everyday
is an effective means of dialysis. This is great news!
