myoglobinuria
Noun: A medical condition characterized by the presence of myoglobin in the urine. Myoglobin is a protein found in muscle cells that stores oxygen. Its presence in urine typically indicates muscle damage or breakdown.
The term is used in medical and clinical contexts to describe a symptom or finding, often associated with conditions that cause rapid muscle tissue destruction (rhabdomyolysis). * The patient's myoglobinuria was a clear sign of severe muscle injury following the accident. * Laboratory tests confirmed myoglobinuria, prompting further investigation into potential causes like extreme physical exertion or toxin exposure.
- Diagnostic Indicator: Myoglobinuria is a key diagnostic clue for rhabdomyolysis. The released myoglobin can damage the kidneys, so its detection is critical.
- The emergency physician immediately checked for myoglobinuria due to the risk of acute kidney injury.
- Differentiation from Hematuria: While both can cause dark urine, myoglobinuria tests negative for intact red blood cells on urine microscopy, distinguishing it from blood in the urine (hematuria).
- The urine was dark brown, suggesting myoglobinuria rather than hematuria.
- Myoglobin (noun): The oxygen-binding protein in muscle tissue whose presence in urine defines myoglobinuria.
- Myoglobinuric (adjective): Relating to or characterized by myoglobinuria.
- The patient was in myoglobinuric renal failure.
- Rhabdomyolysis (noun): A serious syndrome resulting from the breakdown of damaged skeletal muscle, a common cause of myoglobinuria.
