Sickle Cell Nephropathy

Sickle Cell Nephropathy refers to kidney damage caused by sickle cell disease. SCD is a genetic? disorder where red blood cells become misshapen (sickle-shaped), leading to various health issues, including those affecting the kidneys?.

Pathophysiology

Structure

The kidneys filter waste from the blood. In SCN, sickled red blood cells can block tiny blood vessels in the kidneys, impairing their function.

Blood

Sickle-shaped cells reduce oxygen delivery and increase the risk of blockages in kidney vessels, leading to inflammation? and scarring.

Nerve Supply

Nerve damage in SCN can affect kidney function, potentially causing pain? and other neurological symptoms.

Types of Sickle Cell Nephropathy

1. Hyperfiltration: Increased kidney function initially.
2. Hematuria?: Blood in urine? due to damaged blood vessels.
3. Proteinuria?: Excess protein in urine indicating kidney damage.
4. Renal? Insufficiency: Reduced kidney function.
