Calyceal Nephritis

Calyceal nephritis is a type of kidney inflammation that specifically affects the calyces—the chambers within the kidneys where urine collects before moving to the bladder. This condition can cause significant discomfort and may lead to serious kidney issues if not treated promptly.

Before diving into calyceal nephritis, it’s essential to understand the basic structure of the kidneys:

• Kidneys: Two bean-shaped organs located on either side of the spine, just below the rib cage. They filter waste and excess fluids from the blood to form urine.
• Calyces (singular: calyx): These are the small chambers inside the kidneys where urine collects before it flows into the renal pelvis and then to the bladder.

Pathophysiology of Calyceal Nephritis

Structure

Calyceal nephritis affects the calyces within the kidneys. The inflammation can disrupt the normal flow of urine, leading to swelling and damage.

Blood Supply

The kidneys receive blood through the renal arteries. Proper blood flow is crucial for kidney function. In calyceal nephritis, inflammation can affect blood vessels, potentially reducing blood flow and impairing kidney function.

Nerve Supply

Nerves in the kidneys help regulate functions like blood flow and urine production. Inflammation can irritate these nerves, causing pain and discomfort.

Types of Calyceal Nephritis

1. Acute Calyceal Nephritis: Sudden onset, often due to infection.
2. Chronic Calyceal Nephritis: Long-term inflammation, possibly from recurring infections or other underlying conditions.

Causes of Calyceal Nephritis

Here are 20 possible causes:

1. Bacterial infections (e.g., E. coli)
2. Urinary tract infections (UTIs)
3. Kidney stones blocking urine flow
4. Vesicoureteral reflux (urine flowing backward)
5. Structural abnormalities in the kidneys
6. Prolonged catheter use
7. Diabetes
8. High blood pressure
9. Immune system disorders
10. Use of certain medications (e.g., antibiotics)
11. Dehydration
12. Obstruction from tumors
