What is a kidney infection (pyelonephritis)?
A kidney infection, also known as pyelonephritis, is a type of urinary tract infection (UTI) that specifically affects one or both kidneys. It occurs when bacteria or, in rare cases, a virus or fungus, enters the kidneys through the urinary tract. The bacteria typically originate from the bladder or urethra and travel upward.
Pyelonephritis is considered a more severe form of UTI compared to a simple bladder infection (cystitis) because it involves the kidneys, which are essential for filtering waste from the blood and producing urine. If left untreated, a kidney infection can cause significant damage to the kidneys and lead to serious health complications.
Common symptoms of pyelonephritis include:
● High fever (often above 101°F or 38.3°C)
● Persistent pain or discomfort in the lower back or side
● Abdominal pain
● Frequent urination
● Strong, persistent urge to urinate
● Painful or burning sensation during urination
● Cloudy, dark, or bloody urine
● Fatigue
● Nausea and vomiting
● Confusion (more common in older adults)
If you suspect you have a kidney infection, it is important to seek medical attention promptly. A healthcare provider will typically perform a physical examination, inquire about your symptoms, and may order urine tests, blood tests, or imaging studies such as an ultrasound or CT scan to diagnose and evaluate the severity of the infection. Treatment often involves antibiotics to eliminate the infection, and in more severe cases, hospitalization may be required for intravenous antibiotic therapy.
It's crucial to treat kidney infections promptly to prevent complications such as kidney damage, sepsis (a potentially life-threatening infection that spreads throughout the body), or the formation of kidney abscesses.
How common are kidney infections?
Kidney infections, or pyelonephritis, are less common than bladder infections, but they can still occur frequently. The exact prevalence of kidney infections can vary depending on various factors such as age, sex, underlying health conditions, and geographical location.
In general, kidney infections are more common in women than men. This is partly because women have a shorter urethra, which allows bacteria to travel to the kidneys more easily. Hormonal changes during pregnancy can also increase the risk of kidney infections in women.
Furthermore, individuals with certain risk factors are more prone to kidney infections. These include people with urinary tract abnormalities, kidney stones, weakened immune systems, diabetes, or a history of recurrent urinary tract infections.
While precise statistics on the prevalence of kidney infections are not readily available, it is estimated that about 15-20% of women will experience at least one episode of pyelonephritis in their lifetime. The incidence in men is lower, but it can still occur, especially in those with risk factors.
It's worth noting that kidney infections require medical attention, and it's important not to ignore the symptoms or delay seeking treatment. If you suspect you have a kidney infection, it is recommended to consult a healthcare professional for an accurate diagnosis and appropriate management.
How can you tell the difference between a kidney infection and a UTI?
Distinguishing between a kidney infection (pyelonephritis) and a urinary tract infection (UTI) can sometimes be challenging as they share some similar symptoms. However, there are a few key differences that can help differentiate the two conditions:
■ Location of symptoms:
In a UTI, the symptoms primarily affect the lower urinary tract, including the bladder and urethra. Common symptoms include a strong, persistent urge to urinate, painful or burning sensation during urination, and cloudy or bloody urine. On the other hand, a kidney infection involves the kidneys and often causes symptoms such as lower back pain or side pain, fever, and nausea/vomiting in addition to urinary symptoms.
■ Severity of symptoms:
Kidney infections tend to cause more severe and systemic symptoms compared to UTIs. In addition to urinary symptoms, individuals with pyelonephritis often experience high fever (above 101°F or 38.3°C), significant back or side pain, and general fatigue. UTIs typically present with milder symptoms and may not cause fever or significant pain.
■ Systemic signs of infection:
Kidney infections can result in systemic signs of infection, such as fever, chills, and general malaise. These systemic symptoms are less common in UTIs, where symptoms are usually localized to the urinary tract.
■ Response to treatment:
If you have a UTI, prompt treatment with appropriate antibiotics often resolves the infection within a few days, and symptoms improve quickly. However, if the infection progresses to a kidney infection, the symptoms may persist or worsen despite initial treatment, and additional medical intervention may be necessary.
It's important to note that these are general guidelines, and the best way to differentiate between a kidney infection and a UTI is through medical evaluation by a healthcare professional. They will take into account your symptoms, perform a physical examination, and may order laboratory tests (urine analysis, urine culture) or imaging studies (ultrasound, CT scan) to make an accurate diagnosis. If you suspect you have a urinary tract infection, it is recommended to seek medical attention for proper evaluation and treatment.
What are the signs and symptoms of a kidney infection?
The signs and symptoms of a kidney infection (pyelonephritis) can vary from person to person, but common indicators include:
● Back or side pain:
Kidney infections often cause pain in the lower back or side of the affected kidney. The pain can be dull or sharp and may be persistent or intermittent.
● Fever:
A high fever is a common symptom of a kidney infection. It is typically above 101°F (38.3°C). The fever may be accompanied by chills and sweating.
● Urinary symptoms:
Kidney infections are associated with urinary symptoms similar to those of a urinary tract infection (UTI). These symptoms may include:
• Frequent urination:
The need to urinate more often than usual.
• Urgency:
A strong, persistent urge to urinate.
• Painful or burning sensation:
Discomfort or pain during urination.
• Hematuria:
Presence of blood in the urine, which can make it appear pink, red, or cloudy.
• Foul-smelling urine:
Urine may have an unpleasant odor.
● Fatigue and general malaise:
Kidney infections can cause fatigue, weakness, and a general feeling of being unwell.
● Nausea and vomiting:
Some individuals with kidney infections may experience nausea, vomiting, or a loss of appetite.
● Mental confusion (in older adults):
Elderly individuals with kidney infections may exhibit confusion, delirium, or changes in mental status.
It's important to note that not all individuals will experience all of these symptoms, and the severity can vary. If you suspect you have a kidney infection, it is crucial to seek medical attention promptly for diagnosis and treatment. Untreated kidney infections can lead to complications and more severe health issues.
What causes kidney infections?
Kidney infections, or pyelonephritis, are primarily caused by bacterial infections. The most common bacteria responsible for kidney infections is Escherichia coli (E. coli), which normally resides in the intestines but can enter the urinary tract and ascend to the kidneys. Other bacteria, such as Klebsiella, Proteus, or Pseudomonas, can also cause kidney infections, although they are less common.
The bacteria that cause kidney infections typically enter the urinary tract through the urethra and can travel upward into the bladder and then into the kidneys. Several factors can increase the risk of bacterial entry and subsequent kidney infection:
■ Urinary tract obstruction:
Any condition that obstructs the normal flow of urine, such as kidney stones, ureteral strictures, or anatomical abnormalities, can increase the risk of bacterial growth and infection.
■ Urinary catheters:
People with indwelling urinary catheters have a higher risk of developing urinary tract infections, including kidney infections. Catheters can provide a pathway for bacteria to enter the urinary tract.
■ Vesicoureteral reflux (VUR):
VUR is a condition where urine flows backward from the bladder into the ureters and potentially the kidneys. This reflux of urine can introduce bacteria into the kidneys, leading to infection.
■ Weakened immune system:
Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy, are more susceptible to kidney infections.
■ Gender and anatomical differences:
Women are more prone to kidney infections due to their shorter urethra, which allows bacteria to reach the kidneys more easily. Pregnancy can also increase the risk of kidney infections in women.
It's important to note that while bacterial infections are the most common cause, kidney infections can also result from nonbacterial sources, such as viral or fungal infections. However, these cases are relatively rare compared to bacterial infections.
Prompt treatment of urinary tract infections and addressing risk factors can help reduce the likelihood of kidney infections. If you are experiencing symptoms suggestive of a urinary tract infection or kidney infection, it is important to consult a healthcare professional for proper diagnosis and treatment.
How do you get a kidney infection?
Kidney infections, or pyelonephritis, typically occur when bacteria enter the urinary tract and reach the kidneys. The most common route of infection is ascending from the lower urinary tract, such as the bladder or urethra, to the kidneys. Here are the key steps in how a kidney infection can develop:
● Bacterial entry:
Bacteria, most commonly Escherichia coli (E. coli) but also other types such as Klebsiella, Proteus, or Pseudomonas, are the primary culprits in causing kidney infections. These bacteria can enter the urinary tract through various means, including:
• Urethra:
Bacteria can travel from the external opening of the urethra (where urine exits the body) up into the bladder and then further into the kidneys.
• Bladder:
Bacteria can multiply within the bladder, causing a urinary tract infection (UTI), and subsequently ascend to the kidneys.
• Bloodstream:
In rare cases, bacteria from an infection in another part of the body can enter the bloodstream and be carried to the kidneys, causing a kidney infection.
● Urinary tract obstruction:
Any condition that obstructs or hampers the normal flow of urine can increase the risk of kidney infections. Examples include:
• Kidney stones:
Stones that form in the kidneys or ureters can block the flow of urine, creating an environment where bacteria can thrive and cause infection.
• Ureteral strictures:
Narrowing of the ureters due to scar tissue or other causes can impede urine flow and increase the risk of infection.
• Anatomical abnormalities:
Certain structural abnormalities in the urinary tract can make it easier for bacteria to ascend to the kidneys.
● Risk factors:
Certain factors can increase the likelihood of developing a kidney infection. These include:
• Gender:
Women are more prone to kidney infections due to their shorter urethra, which provides a shorter distance for bacteria to travel to the kidneys.
• Sexual activity:
Sexual intercourse can introduce bacteria into the urethra and increase the risk of urinary tract infections that may progress to kidney infections.
• Urinary catheters:
People with indwelling urinary catheters have an increased risk of developing urinary tract infections, including kidney infections.
• Weakened immune system:
Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy, are more susceptible to infections, including kidney infections.
It's important to note that while bacterial infections are the most common cause of kidney infections, nonbacterial sources, such as viral or fungal infections, can also lead to kidney infections, although these instances are relatively rare.
If you suspect you have a kidney infection or are at risk, it's essential to seek medical attention promptly for appropriate diagnosis and treatment to prevent complications and promote recovery.
What are the risk factors for kidney infection?
Several risk factors can increase the likelihood of developing a kidney infection (pyelonephritis). These risk factors include:
■ Gender:
Women are at higher risk of kidney infections compared to men. This is partly due to their shorter urethra, which allows bacteria to reach the bladder and kidneys more easily. The proximity of the urethral opening to the anus in women also increases the risk of bacterial contamination.
■ Urinary tract abnormalities:
Structural abnormalities in the urinary tract can disrupt the normal flow of urine and contribute to the development of kidney infections.
Examples include:
▪ Urinary tract obstruction:
Any condition that blocks or hinders the flow of urine, such as kidney stones, ureteral strictures, or anatomical abnormalities, can increase the risk of bacterial growth and subsequent kidney infection.
▪ Vesicoureteral reflux (VUR):
In this condition, urine flows backward from the bladder into the ureters and potentially the kidneys, providing a pathway for bacteria to reach the kidneys.
■ Urinary catheters:
People who require urinary catheters, such as those with urinary retention or undergoing medical procedures, have an increased risk of developing urinary tract infections, including kidney infections. Catheters can introduce bacteria into the urinary tract and promote their ascent to the kidneys.
■ Weakened immune system:
Individuals with weakened immune systems are more susceptible to infections, including kidney infections. Conditions that can weaken the immune system include HIV/AIDS, diabetes, organ transplantation, chemotherapy, and certain autoimmune disorders.
■ Urinary procedures:
Invasive procedures involving the urinary tract, such as cystoscopy or urinary tract surgeries, can introduce bacteria into the urinary system and increase the risk of kidney infections.
■ Urinary retention:
Conditions that cause incomplete emptying of the bladder, such as an enlarged prostate, neurogenic bladder, or bladder dysfunction, can increase the risk of kidney infections.
■ Sexual activity:
Sexual intercourse can introduce bacteria into the urethra and increase the risk of urinary tract infections, including kidney infections.
■ Pregnancy:
Hormonal changes and anatomical adaptations during pregnancy can affect urinary tract function and increase the risk of kidney infections in women.
It's important to note that while these risk factors increase the likelihood of kidney infections, anyone can develop a kidney infection. Prompt diagnosis and appropriate treatment are essential to prevent complications and promote recovery. If you have any concerns or suspect you have a kidney infection, it is advisable to consult a healthcare professional for evaluation and management.
What are the complications of a kidney infection?
Kidney infections (pyelonephritis) can lead to various complications if left untreated or inadequately treated. These complications can affect the kidneys themselves or other organs and systems in the body. Some potential complications of kidney infections include:
● Kidney damage:
Kidney infections can cause inflammation and damage to the kidney tissues. Prolonged or severe infections can lead to scarring and impairment of kidney function. This can result in chronic kidney disease or even kidney failure, where the kidneys are unable to adequately filter waste products and regulate fluid and electrolyte balance.
● Sepsis:
Severe kidney infections can spread infection to the bloodstream, causing a condition called sepsis. Sepsis is a life-threatening systemic infection that can lead to organ dysfunction or failure. It requires immediate medical attention and can be fatal if not treated promptly.
● Kidney abscess:
In some cases, a kidney infection can lead to the formation of an abscess—a pus-filled cavity—in the kidney. Kidney abscesses may require drainage through a surgical procedure or percutaneous needle aspiration to remove the accumulated pus.
● Hypertension (high blood pressure):
Chronic kidney infections and kidney damage can contribute to the development of hypertension. The kidneys play a crucial role in regulating blood pressure, and when their function is compromised, it can lead to hypertension.
● Recurrent infections:
If the underlying cause of the kidney infection, such as an obstruction or urinary tract abnormality, is not addressed, it can increase the risk of recurrent kidney infections. Frequent episodes of kidney infections can further damage the kidneys and increase the risk of complications.
● Pregnancy complications:
Kidney infections during pregnancy can pose risks to both the mother and the developing fetus. They can increase the risk of preterm labor, low birth weight, and other pregnancy complications.
It's important to note that with prompt and appropriate treatment, the risk of complications from kidney infections is significantly reduced. If you suspect you have a kidney infection or are experiencing symptoms suggestive of it, it is crucial to seek medical attention for proper diagnosis and treatment. Early intervention can help prevent complications and promote recovery.
How is a kidney infection diagnosed?
To diagnose a kidney infection (pyelonephritis), healthcare professionals typically perform a combination of medical evaluation, physical examination, and diagnostic tests. The diagnostic process may include the following:
■ Medical history:
Your doctor will inquire about your symptoms, medical history, and any risk factors that may contribute to kidney infections. They may ask about previous urinary tract infections, kidney stones, urinary tract abnormalities, recent urinary procedures, or conditions that weaken the immune system.
■ Physical examination:
A physical examination helps the doctor assess your overall health and identify any signs of a kidney infection. They may check for tenderness or pain in the back or side, examine your abdomen for any abnormalities, and assess vital signs such as temperature and blood pressure.
■ Urine analysis:
A urinalysis is a common initial test used to detect the presence of infection in the urinary tract. A sample of urine is analyzed for the presence of bacteria, white blood cells (indicating an immune response), red blood cells, and other abnormal components. The presence of bacteria and white blood cells suggests a urinary tract or kidney infection.
■ Urine culture:
If a urinary tract infection is suspected, a urine culture may be performed to identify the specific bacteria causing the infection and determine the most effective antibiotic treatment. This test involves growing the bacteria in the laboratory from a urine sample.
■ Blood tests:
Blood tests may be conducted to assess kidney function, check for signs of infection or inflammation, and evaluate overall health. Elevated white blood cell count and markers of inflammation (such as C-reactive protein or erythrocyte sedimentation rate) may indicate a kidney infection.
■ Imaging studies:
In some cases, imaging studies may be recommended to assess the kidneys and urinary tract for any abnormalities, obstructions, or signs of complications.
Common imaging tests include:
▪ Ultrasound:
An ultrasound uses sound waves to create images of the kidneys and urinary tract. It can help identify kidney stones, abnormalities, or signs of inflammation.
▪ CT scan:
A computed tomography (CT) scan provides detailed cross-sectional images of the kidneys and surrounding structures. It can help detect kidney stones, abscesses, or structural abnormalities.
Based on the results of these diagnostic tests, your healthcare provider can make a diagnosis of a kidney infection and determine the appropriate course of treatment.
It is important to consult a healthcare professional if you suspect a kidney infection or are experiencing symptoms suggestive of it. They will be able to evaluate your condition, confirm the diagnosis, and recommend the most suitable treatment plan.

It's important to note that these symptoms are not exclusive to kidney infections, and other conditions can cause similar manifestations. Only a healthcare professional can provide a definitive diagnosis. If you suspect a kidney infection, it's crucial to seek medical attention promptly. Untreated kidney infections can lead to complications and may require appropriate treatment with antibiotics to prevent further health issues.
How is a kidney infection treated?
Kidney infections (pyelonephritis) are typically treated with a combination of antibiotics and supportive measures. The specific treatment approach may vary based on the severity of the infection, individual factors, and the presence of any complications. Here are the common treatment methods for kidney infections:
■ Antibiotic therapy:
Antibiotics are the primary treatment for kidney infections. The choice of antibiotics depends on factors such as the suspected bacteria causing the infection and local antibiotic resistance patterns. Commonly prescribed antibiotics for kidney infections include fluoroquinolones, cephalosporins, and trimethoprim-sulfamethoxazole. The duration of antibiotic treatment is typically 7 to 14 days, but it may be longer in certain cases.
■ Hospitalization:
In some cases, hospitalization may be necessary, especially for severe kidney infections or if the person is unable to tolerate oral antibiotics. Hospitalization allows for close monitoring, intravenous administration of antibiotics, and supportive care.
■ Fluid and pain management:
Adequate fluid intake is important to help flush out the bacteria and maintain hydration. Pain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or opioids, may be prescribed to manage pain and discomfort.
■ Addressing underlying conditions:
If an underlying cause contributed to the kidney infection, such as urinary tract obstruction or vesicoureteral reflux, it may need to be addressed to prevent future infections.
■ Follow-up care:
It's crucial to complete the full course of antibiotics as prescribed by the healthcare professional, even if symptoms improve before completion. Follow-up appointments may be scheduled to ensure the infection has resolved and to monitor kidney function.
It's important to seek medical attention promptly if you suspect a kidney infection. Early treatment can help prevent complications and promote recovery. If symptoms worsen despite treatment or if new symptoms develop, it's important to notify the healthcare provider.

It is crucial to follow the instructions and recommendations provided by your healthcare professional. This includes taking prescribed medications, such as antibiotics, as directed and completing the full course of treatment. Do not stop taking medications early, even if you start feeling better. If you have any concerns or questions about your treatment plan, consult your healthcare provider for clarification.
■ Rest and prioritize recovery:
Allow yourself sufficient rest to aid in the healing process. Avoid strenuous physical activities that could strain your body and prolong your recovery time. Listen to your body's needs and give yourself the time and space to recover fully.
■ Stay hydrated:
Drink plenty of fluids, especially water, to help flush out bacteria and support proper kidney function. Adequate hydration is essential for recovery. Aim to drink enough fluids to keep your urine light yellow or clear.
■ Maintain a healthy diet:
Eat a balanced diet that includes a variety of nutrient-rich foods, such as fruits, vegetables, whole grains, lean proteins, and healthy fats. Proper nutrition supports your immune system and overall health. Avoid foods that may irritate your urinary tract, such as spicy or acidic foods, until the infection has resolved.
■ Practice good hygiene:
Follow proper hygiene practices, including regular handwashing with soap and water, to prevent the spread of bacteria. Clean the genital area thoroughly and maintain good perineal hygiene. Wipe from front to back after using the toilet to prevent bacteria from the anal area from spreading to the urethra.
■ Communicate with your healthcare provider:
Stay in touch with your healthcare professional throughout your recovery. Report any changes in symptoms or concerns you may have. Attend follow-up appointments as recommended to ensure your progress is monitored and any necessary adjustments to your treatment plan can be made.
■ Take steps to prevent future infections:
Once you have recovered from the kidney infection, it is important to take preventive measures to reduce the risk of future infections. This includes practicing good hygiene, staying hydrated, urinating regularly, and addressing any underlying conditions that may contribute to recurrent infections. Follow the guidance of your healthcare provider regarding preventive strategies.
Remember, self-care during a kidney infection involves a combination of proper medical treatment, rest, hydration, healthy nutrition, and good hygiene practices. By taking care of yourself and following medical advice, you can support your recovery and reduce the risk of complications. If you have any specific concerns or questions about self-care, it is recommended to consult your healthcare professional for personalized guidance.
When should I see my healthcare provider?
It is important to see your healthcare provider if you suspect you have a kidney infection (pyelonephritis) or if you have been diagnosed with one. Prompt medical attention is crucial to receive appropriate treatment and prevent complications. Here are some specific situations when you should see your healthcare provider:
● Symptoms of a kidney infection:
If you experience symptoms such as frequent urination, urgent urination, pain or burning during urination, lower back or side pain, fever, chills, nausea, vomiting, or any other signs of a urinary tract infection (UTI) that are persistent or worsening, it is important to seek medical attention.
● Previous UTIs or kidney infections:
If you have a history of urinary tract infections or kidney infections and suspect you may have another episode, it is advisable to contact your healthcare provider. Recurrent infections may require further evaluation and specific management strategies.
● Complications or severe symptoms:
If you develop severe pain, high fever, worsening symptoms, signs of dehydration, or any other concerning symptoms, it is important to seek immediate medical attention. These may indicate a more severe infection or potential complications that require prompt evaluation and treatment.
● Lack of improvement with treatment:
If you have been on prescribed antibiotics for a kidney infection and do not experience any improvement in your symptoms after a few days or if your symptoms worsen, it is important to contact your healthcare provider. They can assess your condition, determine the next steps, and consider any necessary adjustments to your treatment plan.
● Follow-up appointments:
If you have been diagnosed with a kidney infection and have a follow-up appointment scheduled with your healthcare provider, it is essential to attend that appointment. This allows them to monitor your progress, assess the effectiveness of the treatment, and make any necessary adjustments to ensure proper recovery.
Remember, the above situations are general guidelines, and it is important to trust your instincts. If you are concerned about your symptoms or have any questions, it is always best to contact your healthcare provider for personalized advice and guidance. They are in the best position to evaluate your specific situation and provide appropriate recommendations.
When should I go to ER for a kidney infection?
While most cases of kidney infection (pyelonephritis) can be managed by seeing a healthcare provider in a non-emergency setting, there are situations where it is advisable to go to the emergency room (ER) for immediate medical attention. Here are some indications when you should consider going to the ER for a kidney infection:
■ Severe pain:
If you experience intense or worsening pain in your lower back or side, especially if it is accompanied by other severe symptoms, such as high fever, chills, or difficulty standing or moving, it may be necessary to seek immediate medical attention.
■ High fever and signs of infection:
If you have a high fever above 101°F (38.3°C) that is not responding to over-the-counter fever-reducing medications, along with other symptoms like chills, rapid heartbeat, dizziness, confusion, or severe weakness, it is important to go to the ER. These symptoms may indicate a severe infection or possible complications.
■ Signs of dehydration:
If you are experiencing severe vomiting, diarrhea, or have been unable to keep fluids down, resulting in signs of dehydration such as extreme thirst, dry mouth, dizziness, lightheadedness, or reduced urine output, it is important to seek immediate medical attention to prevent complications.
■ Difficulty breathing or chest pain:
If you are experiencing difficulty breathing or chest pain, it is important to seek emergency medical care immediately. Although these symptoms are not typically associated with kidney infections, they may indicate a more serious condition that requires immediate evaluation.
■ Rapid deterioration of symptoms:
If your symptoms rapidly worsen or if you have a pre-existing condition that puts you at a higher risk for complications (such as diabetes, kidney disease, or a weakened immune system), it is advisable to go to the ER for urgent evaluation and appropriate management.
It is important to remember that these guidelines are general and should not replace professional medical advice. If you are unsure or concerned about your symptoms, it is always best to err on the side of caution and seek immediate medical attention. The ER staff will be able to evaluate your condition, provide appropriate treatment, and determine the necessary steps for your care.
