Sickle Cell Nephropathy (SCN) is a kidney-related complication that arises in individuals with sickle cell disease (SCD). This guide provides a detailed yet simple overview of SCN, including its definition, pathophysiology, types, causes, symptoms, diagnostic tests, treatments, surgeries, preventions, when to seek medical help, and frequently asked questions.
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
- Hyperfiltration: Increased kidney function initially.
- Hematuria: Blood in urine due to damaged blood vessels.
- Proteinuria: Excess protein in urine indicating kidney damage.
- Renal Insufficiency: Reduced kidney function.
- Chronic Kidney Disease: Long-term kidney damage leading to kidney failure.
