Kidney Infection (Pyelonephritis)

Pyelonephritis, commonly referred to as kidney infection, is a serious medical condition characterized by inflammation and infection of the kidney tissue. It is usually caused by a bacterial infection that originates in the urinary tract and ascends to the kidneys. Pyelonephritis can lead to severe complications if left untreated, including kidney damage and systemic infection(sepsis).

Understanding of Kidney Infection:

Pyelonephritis is an infection of the kidney tissue, typically caused by bacteria such as Escherichia coli (E. coli) or Klebsiella pneumoniae. There are two primary types of pyelonephritis:

  • Acute Pyelonephritis: This is a sudden and severe form of kidney infection that develops rapidly and requires prompt medical treatment. Acute pyelonephritis can lead to symptoms such as high grade fever, chills, flank pain, and urinary symptoms.

  • Chronic Pyelonephritis: Chronic pyelonephritis is a long-term condition characterized by recurrent or persistent kidney infections. It can lead to progressive kidney damage and impairment of kidney function over time, potentially resulting in chronic kidney disease.

Causes and Risk Factors:

Pyelonephritis is commonly caused by the ascent of bacteria from the lower urinary tract into the kidneys. Risk factors for developing pyelonephritis include:

  • Urinary Tract Infections (UTIs): Bacterial infections of the bladder or urethra can ascend to the kidneys, leading to pyelonephritis.
  • Structural Abnormalities: Anatomical abnormalities of the urinary tract, such as kidney stones or urinary tract obstructions, can increase the risk of kidney infections.
  • Catheterisation : Long term Indwelling urinary catheters or urinary retention can predispose individuals to bacterial colonisation and infection of the urinary tract.
  • Weakened Immune System: Conditions that weaken the immune system, such as diabetes, HIV/AIDS, or immunosuppressive medications, can increase susceptibility to kidney infections.
  • Gender and Age: Women are more prone to urinary tract infections and, consequently, pyelonephritis. Additionally, infants, elderly individuals, and pregnant women are at higher risk due to physiological changes and decreased immune function.

Common Symptoms:

Pyelonephritis can cause a range of symptoms, including:

  • Fever and Chills: Elevated body temperature and chills are common signs of systemic infection.
  • Flank Pain: Persistent moderate to severe pain in the sides of the abdomen, typically below the ribs, may indicate inflammation of the kidneys.
  • Urinary Symptoms: Symptoms of urinary tract infection, such as frequent urination, urgency, dysuria (painful urination), and hematuria (blood in the urine), may be present.
  • Nausea and Vomiting: Some individuals may experience nausea, vomiting, and general malaise.
  • Fatigue and Weakness: Systemic symptoms such as fatigue, weakness, and lethargy may occur as a result of the body’s immune response to infection.

Diagnosis and Evaluation:

1. Medical History and Physical Examination: A healthcare provider, such as a urologist will begin by obtaining a detailed medical history and performing a physical examination. Key aspects of the medical history may include asking about symptoms, past medical conditions, recent urinary tract infections, and medication use. During the physical examination, the healthcare provider may palpate the abdomen and assess for signs of tenderness or flank pain.

2. Diagnostic Tests: Several diagnostic tests may be performed to confirm the diagnosis of pyelonephritis and assess the severity of the infection. These tests may include:

  • Urinalysis: Analysis of a urine sample can detect the presence of bacteria, white blood cells, and other markers of infection.
  • Blood Tests: Blood tests, such as a complete blood count (CBC), kidney function test (KFT) and blood cultures, may be performed to assess for the presence of systemic infection and to identify the causative bacteria.
  • Imaging Studies: Imaging modalities such as ultrasound, CT scan, or MRI may be used to visualise the kidneys and assess for signs of inflammation or abscess formation.

Treatment and Management:

1. Antibiotic Therapy: The primary treatment for pyelonephritis is antibiotic therapy to eradicate the underlying bacterial infection. Antibiotics are typically selected based on the suspected or identified bacterial pathogens and their susceptibility to antimicrobial agents. Commonly prescribed antibiotics for pyelonephritis include fluoroquinolones, cephalosporins, and trimethoprim-sulfamethoxazole.

2. Supportive Care: In addition to antibiotic therapy, supportive care measures may be implemented to relieve symptoms and promote recovery. These measures may include:

  • Pain Management: Over-the-counter or prescription pain medications may be prescribed to alleviate flank pain and discomfort.
  • Hydration: Adequate fluid intake is essential to maintain hydration and promote urinary flow, which can help flush out bacteria and toxins from the kidneys.
  • Rest and Nutrition: Getting plenty of rest and consuming a balanced diet can support the body’s immune response and aid in recovery from infection.

3. Hospitalization and Intravenous Therapy: Severe cases of pyelonephritis, particularly those associated with complications such as sepsis or renal abscess, may require hospitalization for intravenous antibiotic therapy and supportive care. In the hospital setting, close monitoring of vital signs, fluid balance, and kidney function is essential to ensure timely intervention and prevent complications.

4. Prevention and Follow-Up: Preventive measures may be recommended to reduce the risk of recurrent pyelonephritis and urinary tract infections. These measures may include:

  • Hygiene Practices: Maintaining good hygiene, including proper perineal care and wiping from front to back after urination or bowel movements, can help prevent the spread of bacteria to the urinary tract.
  • Fluid Intake: Drinking plenty of fluids(upto 3 litres/day), particularly water, can help dilute urine and reduce the concentration of bacteria in the urinary tract.
  • Urinary Catheter Care: Proper care and maintenance of urinary catheters can help minimize the risk of catheter-associated urinary tract infections.
  • Periodic Medical Evaluation: Individuals with recurrent urinary tract infections or risk factors for pyelonephritis should undergo thorough medical evaluation and follow-up care with their urologist.
