Acute Kidney Injury

Crystal-induced acute kidney injury (AKI) is a condition where the kidneys become damaged due to the formation of crystals from substances in the blood. This can lead to serious health issues if not addressed promptly. In this article, we will break down the details of crystal-induced AKI, including its causes, symptoms, diagnostics, treatments, and much more, all in simple language.

Acute Kidney Injury (AKI) refers to a sudden decline in kidney function. The kidneys filter waste and extra fluid from the blood, and when they do not work properly, harmful substances can build up in the body.

Types of AKI

1. Prerenal AKI: Caused by reduced blood flow to the kidneys.
2. Intrinsic AKI: Caused by damage to the kidney tissues.
3. Postrenal AKI: Caused by obstruction in the urinary tract.

Pathophysiology

Structure of the Kidneys

The kidneys are two bean-shaped organs located on either side of the spine, just below the rib cage. Each kidney contains tiny structures called nephrons, which filter blood and produce urine.

Blood Supply

The kidneys receive blood from the renal arteries, which branch off from the aorta. They filter about 50 gallons of blood daily, removing waste products and excess substances.

Nerve Supply

The kidneys are connected to the nervous system, which helps regulate blood flow and pressure, affecting kidney function.

Causes of Crystal-Induced Acute Kidney Injury

Several factors can lead to the formation of crystals that cause AKI. Here are 20 common causes:

1. Dehydration: Reduced fluid intake can concentrate substances in the urine, leading to crystals.
2. High Urine Concentration: When urine is overly concentrated, it can precipitate crystals.
3. Medications: Certain drugs can lead to crystal formation (e.g., acyclovir, methotrexate).
4. Infections: Some infections can cause metabolic changes, leading to crystal formation.
5. Gout: Increased uric acid levels can lead to urate crystal formation.
6. Hypercalcemia: Elevated calcium levels can cause calcium phosphate crystals.
7. Tumor Lysis Syndrome: Rapid breakdown of cancer cells releases uric acid.
8. Chronic Kidney Disease: Previous kidney issues can predispose patients to AKI.
9. Genetic Disorders: Conditions affecting metabolism can lead to crystal formation.
10. Diabetes: Poorly controlled diabetes can alter kidney function and crystal formation.
11. Obesity: Increased body weight can lead to metabolic changes affecting kidney health.
12. Hypertension: High blood pressure can damage blood vessels in the kidneys.
13. Dietary Factors: High intake of purines (from red meat, seafood) can increase uric acid levels.
14. Excess Vitamin D: Over-supplementation can lead to increased calcium levels.
15. Renal Tubular Acidosis: This condition affects the kidneys’ ability to excrete acids.
16. Cystinuria: A genetic condition that causes excess cystine in the urine.
17. Chronic Diarrhea: Can lead to dehydration and concentration of urine.
18. Liver Disease: Impaired liver function can affect kidney health and lead to crystal formation.
19. Immune Disorders: Conditions like lupus can affect kidney function.
20. Certain Inherited Metabolic Disorders: These can predispose individuals to crystal formation.
