Kidney Infection (Pyelonephritis) (Symptoms,Causes and Treatment)
Kidney infection, also known as pyelonephritis, is a type of urinary tract infection (UTI) that affects the kidneys. It occurs when bacteria or other infectious agents travel up the urinary tract and reach the kidneys, causing inflammation and infection. Pyelonephritis can be a serious condition and requires prompt medical attention to prevent complications.
Key points about kidney infection (pyelonephritis) include:
1-Causes: The most common cause of kidney infection is the migration of bacteria from the lower urinary tract (bladder or urethra) to the kidneys. The bacteria most often responsible for kidney infections is Escherichia coli (E. coli). Other bacteria and less commonly, viruses and fungi, can also lead to pyelonephritis.
2-Symptoms: The typical symptoms of kidney infection include high fever, chills, severe back or flank pain (pain on the side of the lower back), frequent and painful urination, cloudy or bloody urine, and general feelings of fatigue and malaise. Nausea and vomiting may also occur.
3-Risk Factors: Certain factors increase the risk of developing kidney infections, including being female (as women have a shorter urethra, making it easier for bacteria to enter the urinary tract), having a history of UTIs, having kidney stones or other urinary obstructions, and conditions that weaken the immune system.
4-Diagnosis: A healthcare provider will typically diagnose kidney infection based on a combination of the patient’s symptoms, a physical examination, and laboratory tests. Urinalysis and urine culture are common tests used to identify the type of bacteria causing the infection.
5-Treatment: Treatment for kidney infection usually involves a course of antibiotics to eliminate the bacteria causing the infection. In severe cases or if complications arise, hospitalization may be necessary for intravenous antibiotics and close monitoring.
6-Complications: Without proper treatment, kidney infection can lead to serious complications, such as sepsis (a life-threatening condition resulting from the spread of infection), kidney abscesses (collections of pus in the kidneys), or chronic kidney damage.
7-Prevention: Preventive measures include staying hydrated, urinating regularly, practicing good hygiene, and promptly treating UTIs to prevent their spread to the kidneys.
If you suspect you have a kidney infection or experience symptoms of a UTI, it is crucial to seek medical attention promptly. Early diagnosis and appropriate treatment can help prevent complications and ensure a full recovery.

How common are kidney infections?
Kidney infections, also known as pyelonephritis, are relatively common, especially in certain populations. The frequency of kidney infections can vary depending on factors such as age, sex, overall health, and risk factors. Generally, kidney infections are more common in women than in men.
In the United States, urinary tract infections (UTIs), which can include kidney infections, are among the most common bacterial infections. According to the Centers for Disease Control and Prevention (CDC), UTIs account for millions of healthcare visits each year.
Some factors that can increase the risk of kidney infections include:
1-Sex: Women are more prone to kidney infections due to their shorter urethra, which allows bacteria to enter the urinary tract more easily.
2-Age: Elderly individuals may have weakened immune systems and urinary system changes that can increase the risk of infections.
3-Urinary Tract Abnormalities: Structural abnormalities in the urinary system can make it easier for bacteria to travel to the kidneys.
4-Urinary Catheter Use: People who require urinary catheters have an increased risk of developing UTIs, including kidney infections.
5-Kidney Stones: Individuals with kidney stones may have obstructions that trap bacteria and promote infection.
6-Pregnancy: Pregnant women have hormonal changes that can relax the urinary tract, increasing the risk of infections.
7-Immunosuppression: Conditions or medications that weaken the immune system can make individuals more susceptible to infections.
8-Sexual Activity: Sexual activity can introduce bacteria into the urinary tract, increasing the risk of infection.
While kidney infections are relatively common, they are usually treatable with antibiotics when detected early. Prompt medical attention is essential to prevent complications and ensure a full recovery. If you suspect you have a kidney infection or experience symptoms of a UTI, seek medical evaluation and treatment. Early diagnosis and proper management can lead to successful outcomes and reduce the risk of complications.
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 be important, as kidney infections are generally more severe and require prompt medical attention. Both conditions involve bacterial infections in the urinary tract, but they affect different parts of the urinary system. Here are some key differences between kidney infections and UTIs:
1-Location of Infection:
*UTI: A UTI typically refers to an infection that occurs in the lower urinary tract, which includes the bladder and urethra.
*Kidney Infection: Pyelonephritis is an infection that specifically affects the kidneys, which are located in the upper urinary tract.
2-Symptoms:
*UTI: Common symptoms of a UTI include frequent and painful urination, a strong urge to urinate, cloudy or bloody urine, and discomfort or burning sensation during urination. Some people may also experience lower abdominal pain or pelvic pressure.
*Kidney Infection: In addition to the symptoms of a UTI, kidney infections may cause more severe symptoms such as high fever, chills, severe back or flank pain (pain on the side of the lower back), nausea, vomiting, and general feelings of fatigue and malaise.
3-Severity of Illness:
*UTI: UTIs are generally less severe and can often be treated with oral antibiotics on an outpatient basis.
*Kidney Infection: Pyelonephritis is a more serious condition that can lead to complications if left untreated. It may require hospitalization and intravenous antibiotics for proper management.
4-Presence of Systemic Symptoms:
*UTI: UTIs typically do not cause systemic symptoms like high fever or chills. The symptoms are usually localized to the lower urinary tract.
*Kidney Infection: Kidney infections can lead to systemic symptoms such as fever and chills, indicating that the infection has spread beyond the urinary tract.
5-Physical Examination Findings:
*UTI: Physical examination for a UTI may reveal tenderness in the lower abdomen.
*Kidney Infection: In cases of kidney infection, the physical examination may reveal tenderness or pain in the back or flank area over the kidneys.
If you suspect you have a UTI or kidney infection, it’s essential to seek medical evaluation and diagnosis by a healthcare provider. They can perform a urinalysis, urine culture, and physical examination to determine the location and severity of the infection. Prompt diagnosis and appropriate treatment are crucial to prevent complications and ensure a full recovery.

What causes kidney infections?
Kidney infections, also known as pyelonephritis, are primarily caused by the migration of bacteria or other infectious agents from the lower urinary tract to the kidneys. The most common bacteria responsible for kidney infections is Escherichia coli (E. coli), which normally resides in the intestines. However, when these bacteria enter the urinary tract and ascend to the kidneys, they can cause an infection.
Some common causes and risk factors for kidney infections include:
1-Urinary Tract Infection (UTI): The vast majority of kidney infections begin as lower urinary tract infections (UTIs). Bacteria enter the urethra and travel upward into the bladder, where they can cause a bladder infection (cystitis). If not promptly treated, the bacteria can continue to ascend up the ureters to infect the kidneys.
2-Urinary Tract Abnormalities: Structural abnormalities or congenital conditions in the urinary tract, such as vesicoureteral reflux (a condition where urine flows backward from the bladder to the kidneys), kidney stones, or urinary obstructions, can increase the risk of kidney infections.
3-Urinary Catheter Use: People who require urinary catheters, such as those in the hospital or with certain medical conditions, have an increased risk of developing UTIs and kidney infections.
4-Pregnancy: Pregnant women have hormonal changes that can relax the urinary tract, making it easier for bacteria to travel up to the kidneys.
5-Sexual Activity: Sexual activity can introduce bacteria into the urethra and increase the risk of UTIs and kidney infections in some individuals.
6-Kidney Stones: Kidney stones can create a conducive environment for bacteria to thrive and cause infections in the urinary tract, including the kidneys.
7-Immunosuppression: Conditions or medications that weaken the immune system, such as diabetes or immunosuppressive medications, can increase the risk of kidney infections.
8-Enlarged Prostate: In men, an enlarged prostate can lead to urinary retention, creating conditions favorable for bacterial growth and infection.
It’s essential to treat UTIs promptly to prevent them from progressing to kidney infections. If you experience symptoms of a UTI or kidney infection, seek medical attention for appropriate diagnosis and treatment. Early intervention can help prevent complications and ensure a full recovery. Additionally, practicing good hygiene, staying well-hydrated, and adopting healthy urinary habits can reduce the risk of urinary tract infections and kidney infections.
How do you get a kidney infection?
A kidney infection, also known as pyelonephritis, is typically caused by the migration of bacteria or other infectious agents from the lower urinary tract to the kidneys. The most common route of infection is through the urethra, which is the tube that carries urine from the bladder out of the body. From the urethra, bacteria can travel upward through the urinary tract to infect the bladder (causing cystitis) and, if left untreated, continue to ascend to the kidneys.
Here’s how you can get a kidney infection:
1-Urinary Tract Infection (UTI): The vast majority of kidney infections start as lower urinary tract infections (UTIs). Bacteria, most commonly Escherichia coli (E. coli) from the intestinal flora, enter the urethra and reach the bladder, leading to a UTI. If the UTI is not adequately treated, the bacteria can ascend the urinary tract to infect the kidneys.
2-Sexual Activity: In some cases, sexual activity can introduce bacteria into the urethra, increasing the risk of developing a UTI and, subsequently, a kidney infection.
3-Urinary Tract Abnormalities: Structural abnormalities or congenital conditions in the urinary tract, such as vesicoureteral reflux (a condition where urine flows backward from the bladder to the kidneys), kidney stones, or urinary obstructions, can create conditions that promote the spread of bacteria to the kidneys.
4-Urinary Catheter Use: People who require urinary catheters, such as those in the hospital or with certain medical conditions, are at an increased risk of developing UTIs and kidney infections.
5-Pregnancy: Pregnant women have hormonal changes that can relax the urinary tract, making it easier for bacteria to travel up to the kidneys.
6-Immune System Suppression: Conditions or medications that weaken the immune system, such as diabetes or immunosuppressive medications, can increase the risk of kidney infections.
It’s important to treat UTIs promptly to prevent them from progressing to kidney infections. If you suspect you have a UTI or experience symptoms of a kidney infection, seek medical attention for appropriate diagnosis and treatment. Early intervention can help prevent complications and ensure a full recovery. Additionally, practicing good hygiene, staying well-hydrated, and adopting healthy urinary habits can reduce the risk of urinary tract infections and kidney infections.
What are the risk factors for kidney infection?
Several risk factors can increase the likelihood of developing a kidney infection (pyelonephritis). These factors can make it easier for bacteria to enter and infect the urinary tract, leading to a higher risk of kidney infections. Some common risk factors for kidney infection include:
1-Female Gender: Women are at a higher risk of kidney infections compared to men. This is because women have a shorter urethra, which makes it easier for bacteria to travel up to the bladder and kidneys.
2-Urinary Tract Infections (UTIs): Having a history of recurrent urinary tract infections increases the risk of bacteria ascending to the kidneys and causing kidney infections.
3-Urinary Tract Abnormalities: Structural abnormalities or congenital conditions in the urinary tract can create conditions favorable for bacterial growth and the spread of infection to the kidneys. Examples include vesicoureteral reflux (a condition where urine flows backward from the bladder to the kidneys) and urinary obstructions.
4-Urinary Catheter Use: Individuals who require urinary catheters, such as those in the hospital or with certain medical conditions, have an increased risk of developing UTIs and kidney infections.
5-Pregnancy: Pregnant women have hormonal changes that can relax the urinary tract, making it easier for bacteria to travel up to the kidneys.
6-Sexual Activity: Sexual activity can introduce bacteria into the urethra and increase the risk of developing a UTI and subsequently a kidney infection.
7-Kidney Stones: Kidney stones can create conditions favorable for bacterial growth and infection in the urinary tract, including the kidneys.
8-Immune System Suppression: Conditions or medications that weaken the immune system, such as diabetes or immunosuppressive medications, can increase the risk of kidney infections.
9-Enlarged Prostate: In men, an enlarged prostate can lead to urinary retention and incomplete bladder emptying, creating conditions favorable for bacterial growth and infection.
10-Advanced Age: Elderly individuals may have weakened immune systems and urinary system changes that increase the risk of infections.
11-Recent Urinary Procedures: Recent procedures involving the urinary tract, such as catheterization or cystoscopy, may increase the risk of bacterial entry and infection.
It’s essential to be aware of these risk factors and take preventive measures if necessary. Practicing good hygiene, staying well-hydrated, and adopting healthy urinary habits can help reduce the risk of urinary tract infections and subsequent kidney infections. If you have any risk factors or experience symptoms of a kidney infection, seek medical attention for timely diagnosis and appropriate treatment. Early intervention can prevent complications and promote a full recovery.
What are the complications of a kidney infection?
Kidney infections (pyelonephritis) can be a serious condition and, if left untreated or inadequately managed, they can lead to various complications. Some of the potential complications of a kidney infection include:
1-Sepsis: Untreated or severe kidney infections can cause bacteria to enter the bloodstream, leading to a condition called sepsis. Sepsis is a life-threatening systemic response to infection that can cause widespread inflammation and organ dysfunction.
2-Kidney Abscess: A kidney abscess is a collection of pus that forms within the kidney. It can result from the spread of infection to the kidney tissue. Abscesses may need drainage and prolonged antibiotic treatment.
3-Chronic Kidney Damage: Repeated or untreated kidney infections can cause damage to the kidneys over time, leading to chronic kidney disease (CKD). CKD is a condition in which the kidneys lose their ability to function properly and filter waste products from the blood.
4-Acute Kidney Injury (AKI): In severe cases of kidney infection, the kidneys may experience a sudden and significant decrease in function, resulting in acute kidney injury. AKI is a rapid loss of kidney function that requires immediate medical attention.
5-Pregnancy Complications: Pregnant women with untreated kidney infections are at risk of preterm labor, low birth weight, and other complications that can affect both the mother and the baby.
6-Recurrent Infections: Some individuals may experience recurrent kidney infections, especially if underlying risk factors, such as urinary tract abnormalities, are not addressed.
7-Hypertension (High Blood Pressure): Chronic kidney infections or kidney damage can contribute to the development of hypertension (high blood pressure).
8-Renal Scarring: Severe kidney infections can cause scarring of the kidney tissue, potentially affecting kidney function.
It’s important to seek prompt medical attention if you suspect you have a kidney infection or if you experience symptoms such as high fever, severe back or flank pain, and urinary symptoms. Timely diagnosis and appropriate treatment with antibiotics can help prevent complications and ensure a full recovery.

Can a kidney infection go away by itself?
No, a kidney infection (pyelonephritis) cannot go away by itself without treatment. Kidney infections are bacterial infections that require prompt medical intervention and the use of antibiotics to eliminate the bacteria causing the infection. If left untreated, kidney infections can lead to serious complications and may even be life-threatening.
Unlike some mild urinary tract infections (UTIs) that may resolve on their own with increased fluid intake and proper hygiene, kidney infections involve infection of the kidneys, which are vital organs responsible for filtering waste products and maintaining fluid and electrolyte balance in the body. The infection can spread and lead to severe complications, such as sepsis (a life-threatening condition) and kidney damage.
If you suspect you have a kidney infection or experience symptoms such as high fever, severe back or flank pain, and urinary symptoms, seek immediate medical attention. Your healthcare provider can perform diagnostic tests, such as a urinalysis and urine culture, to confirm the diagnosis and prescribe appropriate antibiotics to treat the infection.
It’s essential to complete the full course of antibiotics as prescribed by your healthcare provider, even if you start feeling better before finishing the medication. This ensures that all bacteria are eradicated and reduces the risk of recurrent infections or antibiotic resistance.
Prompt treatment with antibiotics is crucial to prevent complications and ensure a full recovery from a kidney infection. If you have risk factors for kidney infections or have a history of recurrent infections, discuss preventive measures with your healthcare provider. Practicing good hygiene, staying hydrated, and adopting healthy urinary habits can also reduce the risk of kidney infections and related complications.
What can I do at home for a kidney infection?
While a kidney infection (pyelonephritis) requires medical treatment with antibiotics, there are some home care measures you can take to support your recovery and alleviate discomfort. It’s important to note that these home remedies should complement medical treatment and not replace it. Here are some home care tips for managing a kidney infection:
1-Stay Hydrated: Drink plenty of water to help flush out bacteria from the urinary tract and kidneys. Adequate hydration also helps maintain kidney function and prevents dehydration. Aim to drink enough water throughout the day to keep your urine light yellow or clear.
2-Rest: Allow your body to rest and heal by getting plenty of rest and avoiding strenuous activities.
3-Pain Management: Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can help manage pain and reduce fever. However, avoid nonsteroidal anti-inflammatory drugs (NSAIDs) if you have impaired kidney function or as directed by your healthcare provider.
4-Heat Therapy: Applying a heating pad or warm compress to your back or flank area may help relieve pain and discomfort. Be sure to use a moderate heat setting and avoid direct skin contact to prevent burns.
5-Urinate Regularly: Avoid holding in urine for long periods. Urinate when you feel the need to help prevent the multiplication of bacteria in the bladder.
6-Urinate After Sexual Activity: Urinating after sexual activity helps flush out bacteria that may have entered the urethra during intercourse.
7-Good Hygiene: Practice good personal hygiene to prevent the spread of bacteria to the urinary tract. Always wipe from front to back after using the toilet to prevent bacteria from the anal area reaching the urethra.
8-Avoid Irritants: Avoid using harsh personal care products, such as scented soaps, bubble baths, and feminine hygiene sprays, which can irritate the genital area.
9-Avoid Dehydration: Monitor your fluid intake and ensure you are staying adequately hydrated, especially if you have symptoms like fever or vomiting, which can lead to dehydration.
10-Follow Medical Instructions: Follow your healthcare provider’s instructions regarding prescribed antibiotics and any additional medications they may recommend.
Remember, while home care measures can provide relief and support your recovery, they do not replace the need for medical treatment with antibiotics. If you suspect you have a kidney infection or experience symptoms, seek immediate medical attention. Early diagnosis and appropriate antibiotic treatment are essential to prevent complications and ensure a full recovery.
