What is rhabdomyolysis? Why does urine become soy sauce?

Rhabdomyolysis is an acute injury of striated muscle (skeletal muscle). If the patient repeats the action repeatedly in a short time, it will easily lead to cell membrane rupture, muscle cell necrosis and cell lysis. Myoglobin in necrotic cells seeps into the blood in large quantities, and when it passes through the kidney and is excreted with urine, it will make the urine red, leading to soy sauce urine or hematuria.

If the content of myoglobin is too high, creatine kinase and creatinine in the blood will exceed the standard, resulting in nephrotoxicity, and a large amount of uric acid will be released from necrotic cells. If it is not excreted by drinking water immediately, it may damage renal function and even cause acute renal failure. In addition, necrotic muscle cells will release potassium ions, causing hyperkalemia and arrhythmia.
