Albuminuria is the diseased conitdion of the system indicated by the presence of albumen in the urine. Albuminous matters are found in the urine of those suffering from spermatorrhoea, pyuria, haematuria, haematinuria, etc; Albuminuria, especially of the temporary type, may occur independently of organic diseases of the kidneys or any other organ, although it always exists in Bright's disease at some stage. It sometimes exists without objective symptoms; but, as a rule, the chronic form is accompanied by a pasty complexion and dry skin, with aedema of the eyelids and of cellular tissue of the lower extremities; digestive troubles, such as nausea, flatulence, and constipation; nervous disorders, with headache, lassitude, and muscular weakness; frequent micturition at night, and palpitation of the heart. It often follows congestion of the kidneys in inflammatory disease such as measles, scarlet fever, smallpox, typhoid and malarial fevers, pneumonia, diphtheria, rheumatism, peritonitis, etc. It is found in emphysema, cirrhosis of the liver, organic heart disease, pregnancy, and abdominal tumors when the circulation of the blood is obstructed, and an impoverished state of the blood, such as exists in anaemia, pyaemia, and scurvy, often gives rise to it.
