Pyelonephritis is a type of kidney infection that can be serious if not treated. It happens when bacteria reach the kidneys, often through the urinary tract. Understanding this condition is crucial because, if left untreated, it can lead to severe health problems.
Pathophysiology
Structure of the Kidneys
The kidneys are two bean-shaped organs located on either side of your spine, below the rib cage. They filter blood, remove waste, and produce urine.
Blood Supply to the Kidneys
Each kidney receives blood through the renal arteries, which branch off from the abdominal aorta. This blood carries waste products that the kidneys need to filter out.
Nerve Supply to the Kidneys
The kidneys are supplied by nerves from the autonomic nervous system, which helps regulate their function, including blood flow and urine production.
Types of Pyelonephritis
Acute Pyelonephritis
This is a sudden, severe kidney infection that often causes symptoms like fever and back pain. It’s usually treatable with antibiotics.
Chronic Pyelonephritis
This is a long-term condition that can result from repeated infections. It can lead to kidney damage over time.
Causes of Pyelonephritis
Here are 20 causes of pyelonephritis:
- Bacterial Infections: Most common cause, often from E. coli.
- Urinary Tract Obstruction: Such as kidney stones or enlarged prostate.
- Vesicoureteral Reflux: Urine flows backward from the bladder to the kidneys.
- Catheter Use: Long-term catheter use can introduce bacteria.
- Weakened Immune System: Conditions like diabetes or HIV can increase risk.
- Pregnancy: Hormonal changes can lead to urinary issues.
- Sexual Activity: Can introduce bacteria into the urinary tract.
- Kidney Conditions: Existing kidney problems can make infections more likely.
- Frequent Urinary Tract Infections: Previous infections can increase risk.
- Dehydration: Less urine can lead to higher concentrations of bacteria.
- Certain Medications: Some drugs can affect kidney function.
- Poor Hygiene: Can increase the risk of urinary infections.
- Kidney Surgery: Can lead to infections.
- Genetic Predisposition: Some people may be more prone to infections.
- Chronic Health Conditions: Such as high blood pressure.
- Obesity: Can contribute to urinary problems.
- Age: Older adults have a higher risk.
- Menopause: Hormonal changes can affect urinary health.
- Dialysis: Can introduce bacteria into the bloodstream.
- Urinary Tract Malformations: Congenital issues with the urinary system.
