What is "proteinuria"

1911, Modern Latin, from French protéinurie; see protein + urine + abstract noun ending -ia.

n. excessive protein in the urine.

n. the presence of excessive protein (chiefly albumin but also globulin) in the urine; usually a symptom of kidney disorder [syn: albuminuria]

Proteinuria ( or ; from protein and urine) means the presence of an excess of serum proteins in the urine. The excess protein in the urine often causes the urine to become foamy, although foamy urine may also be caused by bilirubin in the urine ( bilirubinuria), retrograde ejaculation, pneumaturia (air bubbles in the urine) due to a fistula, or drugs such as pyridium.
