Rhabdomyolysis
Rhabdomyolysis is the breakdown of muscle tissue that leads to the release of muscle fiber contents into the blood. These substances are harmful to the kidney and often cause kidney damage.
Causes
When muscle is damaged, a protein called myoglobin is released into the bloodstream. It is then filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells.
Rhabdomyolysis may be caused by injury or any other condition that damages skeletal muscle.
Problems that may lead to this disease include:
- Trauma or crush injuries
-
Use of drugs such as
cocaine
, amphetamines, statins,
heroin
, or PCP
Cocaine
A toxicology screen refers to various tests that determine the type and approximate amount of legal and illegal drugs a person has taken.
Heroin
A toxicology screen refers to various tests that determine the type and approximate amount of legal and illegal drugs a person has taken.
- Genetic muscle diseases
- Extremes of body temperature
- Ischemia or death of muscle tissue
- Low phosphate levels

- Severe exertion, such as marathon running or calisthenics
- Lengthy surgical procedures
- Severe dehydration
Symptoms
Symptoms may include:
- Dark, red, or cola-colored urine
- Decreased urine output
- General weakness

Weight gain (unintentional)
Unintentional weight gain is when you gain weight without trying to do so and you are not eating or drinking more.
Exams and Tests
A physical exam will show tender or damaged skeletal muscles.
The following tests may be done:
-
Creatine kinase
(CK) level
Creatine kinase
Creatine phosphokinase (CPK) is an enzyme in the body. It is found mainly in the heart, brain, and skeletal muscle. This article discusses the test...
- Serum calcium
-
Serum myoglobin
Serum myoglobin
The myoglobin blood test measures the level of the protein myoglobin in the blood. Myoglobin can also be measured with a urine test.
-
Serum potassium
Serum potassium
This test measures the amount of potassium in the fluid portion (serum) of the blood. Potassium (K+) helps nerves and muscles communicate. It also ...

Urine myoglobin
The myoglobin urine test is done to detect the presence of myoglobin in urine. Myoglobin can also be measured with a blood test.
This disease may also affect the results of the following tests:

Treatment
You will need to get fluids containing bicarbonate to help prevent kidney damage. You may need to get fluids through a vein (IV). Some people may need kidney dialysis.
Your health care provider may prescribe medicines including diuretics and bicarbonate (if there is enough urine output).
Hyperkalemia and low blood calcium levels (hypocalcemia) should be treated right away. Kidney failure should also be treated.
Hyperkalemia
High potassium level is a problem in which the amount of potassium in the blood is higher than normal. The medical name of this condition is hyperka...

Outlook (Prognosis)
The outcome depends on the amount of kidney damage . Acute kidney failure occurs in many people. Getting treated soon after rhabdomyolysis begins will reduce the risk of permanent kidney damage.
Kidney damage
Injury to the kidney and ureter is damage to the organs of the upper urinary tract.
People with milder cases may return to their normal activities within a few weeks to a month. However, some people continue to have problems with fatigue and muscle pain.
Possible Complications
Complications may include:
-
Acute tubular necrosis
Acute tubular necrosis
Acute tubular necrosis is a kidney disorder involving damage to the tubule cells of the kidneys, which can lead to acute kidney failure.
-
Acute renal failure

When to Contact a Medical Professional
Call your provider if you have symptoms of rhabdomyolysis.
Prevention
Drink plenty of fluids after strenuous exercise. This will help to dilute your urine and flush any myoglobin that is released from your muscles out of your kidneys. Also drink a lot of fluids after any condition that may have damaged skeletal muscle.
