Renal pelvis infection, often referred to as pyelonephritis, is an infection that affects the renal pelvis, the area of the kidney where urine collects before moving to the bladder. Understanding this condition is crucial for effective treatment and prevention.
Pathophysiology
Structure
- Renal Pelvis: The funnel-shaped structure in the kidney that collects urine from the kidney and channels it into the ureter.
- Kidneys: Organs responsible for filtering blood, removing waste, and balancing fluids and electrolytes.
Blood Supply
- The kidneys receive blood through the renal arteries, which branch off from the aorta. The blood supply is vital for filtering and excreting waste.
Nerve Supply
- The kidneys are innervated by the autonomic nervous system, which helps regulate kidney function, including blood flow and urine production.
Types of Renal Pelvis Infection
- Acute Pyelonephritis: A sudden and severe infection.
- Chronic Pyelonephritis: A long-term infection that can lead to kidney damage.
Causes of Renal Pelvis Infection
There are many potential causes of renal pelvis infections, including:
- Bacterial Infections: The most common cause, often from E. coli.
- Urinary Tract Infections (UTIs): Can spread from the bladder to the kidneys.
- Obstructions: Such as kidney stones or tumors blocking urine flow.
- Structural Abnormalities: Congenital defects in the urinary tract.
- Vesicoureteral Reflux: A condition where urine flows backward from the bladder to the kidneys.
- Weakened Immune System: Conditions like diabetes can increase susceptibility.
- Catheter Use: Indwelling catheters can introduce bacteria.
- Pregnancy: Hormonal changes and pressure on the urinary tract can lead to infections.
- Frequent UTIs: Recurring infections can spread to the kidneys.
- Sexual Activity: Can introduce bacteria into the urinary tract.
- Poor Hygiene: Inadequate cleaning can lead to infections.
- Dehydration: Inadequate fluid intake can concentrate urine and promote infection.
- Age: Older adults are at higher risk.
- Chronic Kidney Disease: Affects kidney function and immunity.
- Neurogenic Bladder: Nerve damage affects bladder control, increasing infection risk.
- Surgical Procedures: Operations involving the urinary tract can lead to infections.
- Radiation Therapy: Can affect the urinary tract’s integrity.
- Immune Disorders: Conditions that weaken the immune system can increase risk.
- Foreign Bodies: Such as stents or surgical implants in the urinary tract.
- End-stage Renal Disease: Increased vulnerability to infections.
Symptoms of Renal Pelvis Infection
Patients with a renal pelvis infection may experience various symptoms, including:
- Fever: Elevated body temperature is a common sign of infection.
- Chills: Shivering due to fever or infection.
