A minor calyx infection occurs when bacteria enter the minor calyces of the kidneys, leading to inflammation and infection. The kidneys have structures called calyces, which collect urine before it moves to the bladder. The minor calyces are smaller branches that receive urine from the renal pyramids.
Infections in the minor calyces can lead to more severe kidney infections if not treated promptly. Understanding the condition helps in early detection and effective management.
Pathophysiology
Structure
- Kidneys: Two bean-shaped organs filtering blood to produce urine.
- Calyces: Chambers in the kidneys that collect urine.
- Minor Calyces: Smaller branches collecting urine from renal pyramids.
- Major Calyces: Larger chambers formed by minor calyces merging.
Blood Supply
- Renal Arteries: Supply oxygen-rich blood to the kidneys.
- Peritubular Capillaries: Surround kidney tubules, facilitating exchange.
Nerve Supply
- Sympathetic Nerves: Control blood flow and filtration rate.
- Sensory Nerves: Detect pain and other sensations.
How Infection Occurs
Bacteria can travel from the bladder to the kidneys via the ureters. Once in the minor calyces, they can multiply, causing inflammation and infection.
Types of Minor Calyx Infections
- Acute Pyelonephritis: Sudden and severe kidney infection.
- Chronic Pyelonephritis: Long-lasting infection leading to kidney damage.
- Reflux Nephropathy: Infection due to urine flowing backward from the bladder to the kidneys.
Causes
Minor calyx infections are primarily caused by bacteria, but several factors can increase the risk:
- Bacterial Infection: Most commonly E. coli.
- Urinary Tract Blockage: Stones or tumors obstruct urine flow.
- Vesicoureteral Reflux: Urine flows back into the ureters.
- Weakened Immune System: Increases susceptibility to infections.
- Diabetes: High sugar levels can promote bacterial growth.
- Female Anatomy: Shorter urethra increases UTI risk.
