Proteinuria

It is the urinary excretion of protein more than normal

Despite protein retaining properties of glomerular membrane,some protein passes into filtrate.In proximal tubules filtered proteins are almost totally reabsorbed.

Types:

A. Microproteinuria

It is the condition characterized by increased urinary albumin excretion but insufficient to be positive on urinary dipstick test

B. Microproteinuria

Clinical types of proteinuria:

1. Asymptomatic Proteinuria

2. Moderate Proteinuria

3. Massive Proteinuria

Causes of Proteinuria:

Glomerulonephritis

Pyelonephritis

Nephroyic syndrome

Urinary tract infection

Preeclampsia

Acute infection

Leukaemia

Consequences of proteinuria:

1. Hypoalbuminemia

2. Edema

3. Hypotonic hypervolemia

4. Hyperlipidemia

5. Loss of transport proteins
