The kidneys are vital organs that filter waste from the blood, producing urine that travels through a series of tubes called the urinary tract. Inside each kidney, urine collects in small chambers called calyces (singular: calyx). There are major calyces and minor calyces.
Major calyx reflux occurs when urine flows backward from a major calyx into the kidney’s collecting system instead of moving forward toward the bladder. This abnormal flow can lead to various complications, including kidney damage.
Pathophysiology
Understanding how major calyx reflux affects the body requires a look at the urinary system’s structure, blood supply, and nerve connections.
Structure
- Kidneys: Bean-shaped organs that filter blood to produce urine.
- Calyces: Chambers within the kidneys that collect urine. Major calyces are larger and receive urine from multiple minor calyces.
- Ureters: Tubes that carry urine from the kidneys to the bladder.
- Bladder: Stores urine until it is excreted.
- Urethra: Tube through which urine exits the body.
Blood Supply
- Renal Arteries: Supply blood to the kidneys.
- Renal Veins: Carry filtered blood away from the kidneys.
- Capillaries: Tiny blood vessels within the kidneys where filtration occurs.
Nerve Supply
- Autonomic Nerves: Regulate kidney functions like blood flow and urine production.
- Sensory Nerves: Detect pain and other sensations within the kidneys and urinary tract.
In major calyx reflux, the normal one-way flow of urine is disrupted due to structural or functional issues, causing urine to flow backward into the major calyx.
Types of Major Calyx Reflux
- Primary Caliceal Reflux: Caused by inherent defects in the urinary system’s structure.
- Secondary Caliceal Reflux: Results from other urinary conditions like obstructions or infections.
Causes
Here are 20 common causes of major calyx reflux:
- Congenital Anomalies: Birth defects in the urinary tract.
