Bence Jones proteinuria

The presence of BENCE JONES PROTEIN in the urine.

proteinuria

an excess of serum proteins in the urine; an important indicator of renal disease. It is a constant finding in glomerulonephritis, renal infarction, amyloidosis and nephrosis, but is also common in congestive heart failure and renal ischemia of all kinds. The significance of proteinuria as an indicator of renal disease is greatly enhanced by the presence of renal casts in the urine.

Bence Jones proteinuria
neonatal proteinuria
occurs transiently during the period of intestinal absorption of proteins, some of which are small enough to pass the glomerular membrane.
