The kidneys are vital organs that filter waste from the blood and produce urine. Each kidney contains structures called calyces (singular: calyx), which are cup-like cavities that collect urine before it moves to the ureter and then to the bladder. There are minor calyces and major calyces:
- Minor Calyces: Smaller cavities that collect urine directly from the kidney’s filtering units.
- Major Calyces: Larger cavities formed by the convergence of several minor calyces. Each major calyx drains urine into the renal pelvis, the central part of the kidney.
The major calyx plays a crucial role in urine drainage. Any disease affecting it can disrupt urine flow, leading to complications like kidney damage, infections, and pain.
Pathophysiology
Structure
- Location: Located within each kidney.
- Composition: Composed of connective tissue lined with urothelium (a type of tissue that lines parts of the urinary system).
- Function: Collects urine from minor calyces and channels it to the renal pelvis.
Blood Supply
- Arterial Supply: Major calyces receive blood primarily from the renal arteries, which branch into smaller arteries supplying different parts of the kidney.
- Venous Drainage: Blood is drained via the renal veins, which carry filtered blood back to the heart.
Nerve Supply
- Autonomic Nervous System: The major calyx is innervated by sympathetic nerves that help regulate blood flow and the contraction of smooth muscles.
- Sensory Nerves: Provide sensation, which can contribute to pain perception when diseased.
Types of Major Calyx Diseases
- Calyceal Obstruction
- Blockage preventing urine flow.
- Calyceal Diverticulum
- Pouch-like structures forming in the calyx.
- Calyceal Fistula
- Abnormal connection between the calyx and other structures.
- Calyceal Rupture
- Tearing or bursting of the calyx.
- Calyceal Infection (Pyelitis)
- Inflammation due to infection.
- Calyceal Stones (Nephrolithiasis)
- Kidney stones forming in the calyx.
