myoglobinuria

Internal medicine The loss of myoglobin in urine
Myoglobinuria, etiology  
Connective Tissue Disease Polymyositis, dermatomyositis
Hereditary Carnitine palmityl transferase deficiency, glycogen storage disease type V–phosphorylase deficiency, McArdle's disease, myopathies associated with glycogen or lipid storage, paroxysmal familial myoglobinuria, malignant hyperthermia, periodic paralysis
Infection
 Bacteria–eg, Legionnaire's disease
 Parasites–eg, trichinosis, toxoplasmosis
 Viral–eg, EBV, influenza, herpes
Toxins Alcohol–alcoholic myopathy, carbon monoxide, phencyclidine–PCP, 'angel dust', ethylene glycol, insect venom, some diuretics, Haff disease–historic interest
Trauma Crush injury, excess/prolonged physical exertion–eg, marathon running, severe muscle injury, crush injury
Etcetera Hyperthermia, infarction due to vascular occlusion, seizures
The diagnosis is based on clinical suspicion–especially with bright red urine and ↑ CK

myoglobinuria

The presence of MYOGLOBIN in the urine. This may occur when there is an excessive rate of breakdown of muscle (rhabdomyolysis) with release of myoglobin into the blood.

Most researchers [12,13] believe that the non-infectious hyperthermia seen in NMS is related to disruption of dopamine receptors in the hypothalamus; that hyperfunction of the sympathetic nervous system (manifested as tachycardia, polypnea, hypertension, sweating, etc.) is the result of the dopamine antagonists' effects on the function of the autonomic nervous system; and that obstruction of dopamine receptors in the striatum results in muscle rigidity, tremor, and the catabolism of voluntary muscles (leading to myoglobinuria and increased serum creatine kinase).
In humans, a severe muscular lesion such as rhabdomyolysis is biochemically characterized by myoglobinaemia, myoglobinuria and increase in serum levels of muscular enzymes (in the absence of myocardial lesion), particularly of CK (increase above 5-fold the normal value) (MELLI & CHAUDHRY, 2005; AROCH et al., 2010).
