Calyceal Injury

Pathophysiology

Structure of the Kidney

The kidneys are vital organs responsible for filtering blood, removing waste, and regulating fluid balance. They consist of several structures, including:

• Calyces: The minor and major calyces collect urine from the renal pyramids.
• Renal Pelvis: The central cavity that funnels urine into the ureter.
• Nephrons: The functional units that filter blood and form urine.

Blood Supply

The kidneys receive blood through the renal arteries, branching off from the abdominal aorta. Each kidney has a rich blood supply, allowing for effective filtration.

Nerve Supply

The kidneys are innervated by the autonomic nervous system, which regulates blood flow and renal function.

Types of Calyceal Injury

1. Acute Calyceal Injury: Sudden damage often due to trauma or infection.
2. Chronic Calyceal Injury: Long-term damage, usually due to conditions like hypertension or diabetes.
3. Traumatic Calyceal Injury: Resulting from blunt or penetrating trauma.
