Chronic Pyelonephritis

Chronic pyelonephritis is a condition that affects the kidneys, causing inflammation and damage over an extended period. This condition can lead to various health complications if left untreated. In this article, we will discuss the causes, symptoms, and treatment options for chronic pyelonephritis.

What is Chronic Pyelonephritis?

Chronic pyelonephritis is a long-term kidney infection, often resulting from untreated or recurrent infections.  Over time, chronic pyelonephritis can lead to kidney scarring and impaired kidney function.

Causes of Chronic Pyelonephritis

Chronic pyelonephritis is commonly caused by untreated or recurrent urinary tract infections (UTIs). These infections can allow bacteria to ascend from the bladder to the kidneys, leading to kidney damage over time. Conditions like kidney stones or urinary obstructions can also contribute to the development of chronic pyelonephritis.

Symptoms of Chronic Pyelonephritis

  1. Flank Pain: One of the most common symptoms is persistent pain in the lower back, often on one side.
  2. Frequent Urination: Individuals with chronic pyelonephritis may experience an increased need to urinate, especially at night.
  3. Fever: Persistent low-grade fever is a common sign of kidney infection.
  4. Fatigue: Kidney damage can lead to anemia and fatigue.
  5. Blood in Urine: Hematuria, or blood in the urine, may occur.
  6. Urinary Tract Infections: Recurrent UTIs may be a sign of underlying chronic pyelonephritis.

Diagnosis of Chronic Pyelonephritis

If you suspect chronic pyelonephritis, it’s crucial to consult a healthcare professional. They can diagnose the condition through various tests, including:

  1. Urinalysis: This test examines the urine for signs of infection or kidney damage.
  2. Blood Tests: Blood tests can reveal elevated white blood cell counts and markers of kidney function.
  3. Imaging: Imaging studies like ultrasound, CT scans, or MRI can provide detailed views of the kidneys to detect any abnormalities.


Various imaging techniques provide valuable insights into the condition of the kidneys. Common imaging methods include ultrasound, CT scans, and MRI.

Ultrasound: An ultrasound is a non-invasive imaging method that uses sound waves to create images of the kidneys. It can show the size and shape of the kidneys and reveal any structural abnormalities, such as kidney stones or obstructions. Ultrasound is often used as a first-line diagnostic tool for chronic pyelonephritis.

CT Scan: Computed Tomography (CT) scans are highly detailed imaging tests that can provide a more comprehensive view of the kidneys. They are particularly useful in detecting kidney stones, abscesses, or other anatomical changes caused by chronic pyelonephritis. CT scans offer a more detailed assessment of the extent of kidney damage.

MRI: Magnetic Resonance Imaging (MRI) is another imaging option that provides detailed cross-sectional views of the kidneys. While less commonly used than ultrasound and CT scans, MRI may be recommended in specific cases, especially when a more detailed evaluation of kidney tissues is needed.

Imaging studies are essential for healthcare professionals to confirm the diagnosis of chronic pyelonephritis, assess the severity of kidney damage, and guide treatment decisions. These diagnostic tools help healthcare providers make informed decisions about the most appropriate course of action to manage chronic pyelonephritis effectively.

Treatment Options

The primary goal of treating chronic pyelonephritis is to manage symptoms, prevent complications, and preserve kidney function. Treatment may include:

  1. Antibiotics: Bacterial infections are treated with antibiotics to clear the infection.
  2. Pain Management: Over-the-counter or prescription pain relievers can help manage flank pain.
  3. Fluid Intake: Staying well-hydrated is essential to flush out bacteria from the urinary tract.
  4. Lifestyle Changes: Avoiding irritants like caffeine and alcohol can reduce discomfort.
  5. Surgery: In severe cases with kidney damage, surgical intervention may be necessary.

Preventing Chronic Pyelonephritis

Prevention is key when it comes to chronic pyelonephritis. Consider these measures to reduce your risk:

  1. Stay Hydrated: Drinking enough water can help prevent UTIs.
  2. Practice Good Hygiene: Proper hygiene, especially after bowel movements, can reduce the risk of UTIs.
  3. Empty Your Bladder: Don’t hold urine for extended periods, as this can increase the risk of infection.
  4. Treat UTIs Promptly: If you experience symptoms of a urinary tract infection, seek treatment promptly to prevent it from spreading to the kidneys.


Chronic pyelonephritis is a condition that can lead to kidney damage if left untreated. It’s essential to be aware of the symptoms and seek medical attention if you suspect this condition. Preventive measures, like staying hydrated and practicing good hygiene, can significantly reduce the risk of developing this condition. If you or someone you know experiences symptoms of chronic pyelonephritis, consult a healthcare professional for a thorough evaluation and appropriate treatment.
