myoglobinuria(redirected from paralytic myoglobinuria)
Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.
the presence of myoglobin in the urine.
Excretion of myoglobin in the urine; results from muscle degeneration, which releases myoglobin into the blood; occurs in certain types of trauma (crush syndrome), advanced or protracted ischemia of muscle, or as a paroxysmal process of unknown etiology.
Excretion of myoglobin in the urine.
Etymology: Gk, mys + L, globus + Gk, ouron, urine
the presence of myoglobin, an oxygen-storing pigment of muscle tissue, in the urine. The condition usually occurs after massive muscle injury, physical trauma, or electrical injury. The urine has a brown discoloration.
myoglobinuriaInternal medicine The loss of myoglobin in urine
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
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
Excretion of myoglobin in urine; results from muscle degeneration, which releases myoglobin into the blood; occurs in certain types of trauma (e.g., crush syndrome), advanced or protracted ischemia of muscle, or as a paroxysmal process of unknown etiology.
myoglobinuriaThe 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.
Reddish urine caused by excretion of myoglobin, a breakdown product of muscle.

Meyer-Betz disease - Synonym(s): Meyer-Betz syndrome
Meyer-Betz syndrome - excretion of myoglobin in the urine resulting from muscle degeneration. Synonym(s): Meyer-Betz disease; myoglobinuria
the presence of myoglobin in the urine. It is evidence of severe muscle degeneration, though all such degenerations do not necessarily lead to myoglobinuria; it depends on the content of the pigment in the muscle and the renal threshold for it. The urine is red to dark red-brown, but in severe cases may be almost black.
