Introduction
A kidney infection, medically known as pyelonephritis, is a bacterial infection that affects one or both kidneys. Although urinary tract infections (UTIs) are more common in women, men can also develop kidney infections, especially when an underlying urinary problem is present. If left untreated, a kidney infection may lead to permanent kidney damage, bloodstream infection (sepsis), or chronic kidney disease.
Understanding the causes of kidney infection in males, recognizing the warning signs, and seeking early treatment can help prevent serious complications.
At Prabhakar Bhurke Clinic, our super specialist nephrologist offers advanced diagnosis, evidence-based treatment, and long-term kidney care for patients with kidney infections and other kidney disorders.
What Is a Kidney Infection?
A kidney infection occurs when bacteria enter the urinary tract and travel upward to the kidneys. The infection usually begins in the bladder or urethra and spreads if it is not treated promptly.
Because the kidneys filter blood and remove waste from the body, infections affecting these organs require immediate medical attention.
Common Kidney Infection Causes in Males
Several medical conditions can increase the risk of kidney infections in men.
Urinary Tract Infection (UTI)
The majority of kidney infections begin as untreated bladder or urinary tract infections. Bacteria travel upward through the urinary tract and infect the kidneys.
Enlarged Prostate (Benign Prostatic Hyperplasia)
An enlarged prostate may partially block the flow of urine, allowing bacteria to remain in the urinary tract and multiply. This significantly increases the risk of urinary and kidney infections.
Kidney Stones
Kidney stones can obstruct urine flow and trap bacteria inside the urinary tract, making infections more likely.
Urinary Tract Obstruction
Any blockage preventing normal urine drainage can increase infection risk.
Common causes include:
-
Kidney stones
-
Enlarged prostate
-
Ureter narrowing
-
Urinary tract abnormalities
Diabetes
Poorly controlled diabetes weakens the body's immune system and makes bacterial infections more common, including kidney infections.
Weak Immune System
Individuals with reduced immunity due to chronic illness, medications, or certain medical conditions have a higher risk of developing kidney infections.
Long-Term Urinary Catheter
Urinary catheters may introduce bacteria into the urinary tract, increasing the risk of infection, particularly when used for prolonged periods.
Structural Abnormalities of the Urinary Tract
Some men are born with abnormalities affecting urine flow, making repeated infections more likely.
Previous Kidney or Urinary Infections
Men who have experienced repeated urinary tract infections are more likely to develop kidney infections again.
Risk Factors
Men are at greater risk if they have:
-
Diabetes
-
High blood pressure
-
Enlarged prostate
-
Kidney stones
-
Chronic kidney disease
-
Recurrent urinary tract infections
-
Urinary catheter
-
Weak immune system
-
Urinary obstruction
-
Older age
Early management of these conditions helps reduce the likelihood of kidney infection.
Symptoms of Kidney Infection in Males
Symptoms often develop suddenly and may include:
-
Pain in the side or back (flank pain)
-
Fever
-
Chills
-
Burning sensation while urinating
-
Frequent urination
-
Urgent need to urinate
-
Blood in the urine
-
Cloudy or foul-smelling urine
-
Nausea and vomiting
-
Fatigue
-
Weakness
-
Loss of appetite
If these symptoms occur, prompt medical evaluation is important.
Possible Complications
Without treatment, kidney infections can lead to:
-
Permanent kidney scarring
-
Reduced kidney function
-
Chronic kidney disease
-
Kidney abscess
-
Bloodstream infection (sepsis)
-
Recurrent kidney infections
Early treatment greatly reduces the risk of these complications.
How Is a Kidney Infection Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a complete evaluation to determine the cause and severity of the infection.
Medical History and Physical Examination
Your nephrologist will assess:
-
Current symptoms
-
Previous urinary infections
-
Kidney stone history
-
Prostate-related symptoms
-
Medical conditions such as diabetes
-
Current medications
Blood Tests
Investigations may include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Complete Blood Count (CBC)
-
Electrolyte levels
These tests evaluate kidney function and detect infection.
Urine Tests
Urine investigations may include:
-
Urinalysis
-
Urine Culture
-
Urine Microscopy
-
Urine Protein Testing
Urine culture helps identify the bacteria responsible and guides antibiotic treatment.
Imaging Studies
If necessary, imaging may include:
-
Kidney Ultrasound
-
CT Scan
-
MRI in selected cases
These tests help identify kidney stones, urinary obstruction, abscesses, or structural abnormalities.
Treatment for Kidney Infection
Treatment depends on the severity of the infection and the underlying cause.
Antibiotic Therapy
Most kidney infections require antibiotics. The choice of antibiotic depends on urine culture results, the severity of the infection, and the patient's overall health.
Pain and Fever Control
Appropriate medications may be recommended to reduce pain and fever while avoiding medicines that may affect kidney function.
Hydration
Adequate fluid intake supports recovery unless restricted because of advanced kidney disease or heart conditions.
Treatment of Underlying Conditions
Managing kidney stones, enlarged prostate, diabetes, or urinary obstruction is essential to prevent future infections.
Hospitalization
Patients with severe infections, persistent vomiting, or signs of sepsis may require hospital admission for intravenous antibiotics and supportive care.
Tips to Prevent Kidney Infections
Reduce your risk by:
-
Drinking enough water unless advised otherwise.
-

Frequently Asked Questions (FAQs)
What causes kidney infections in men?
Kidney infections are commonly caused by bacteria spreading from the bladder to the kidneys. Enlarged prostate, kidney stones, urinary obstruction, diabetes, and weakened immunity increase the risk.
Are kidney infections serious?
Yes. Without treatment, kidney infections can cause permanent kidney damage and serious bloodstream infections.
Can kidney infections recur?
Yes. Men with kidney stones, enlarged prostate, urinary tract abnormalities, or uncontrolled diabetes have a higher chance of recurrent infections.
Can kidney infections be prevented?
Many cases can be prevented through early treatment of urinary tract infections, proper hydration, diabetes control, and treatment of urinary obstruction.
