Introduction
Urinary tract infections (UTIs) are among the most common bacterial infections, often affecting the bladder or urethra. However, when a UTI spreads upward to the kidneys, it can become a kidney infection (pyelonephritis)—a potentially serious condition that requires prompt medical attention.
If left untreated, a kidney infection can damage kidney tissue, reduce kidney function, and in severe cases, lead to complications such as sepsis or permanent kidney damage.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides expert diagnosis, comprehensive kidney evaluations, advanced diagnostic testing, personalized treatment plans, and long-term care for kidney infections, recurrent UTIs, and other kidney disorders.
Can a UTI Affect the Kidneys?
Yes. A urinary tract infection can spread from the bladder through the ureters to one or both kidneys. This is called acute pyelonephritis.
Although many bladder infections respond well to treatment, delaying medical care increases the risk of the infection reaching the kidneys.
Early diagnosis and appropriate antibiotic treatment help prevent complications.
What Is a Kidney Infection?
A kidney infection is a bacterial infection involving one or both kidneys.
It usually develops when bacteria travel upward from:
-
The urethra
-
The bladder
-
The lower urinary tract
Kidney infections require prompt medical treatment because they are more serious than lower urinary tract infections.
Symptoms of a UTI Affecting the Kidneys
A kidney infection may cause:
-
Fever
-
Chills
-
Pain in the back or side (flank pain)
-
Pain below the ribs
-
Burning while urinating
-
Frequent urination
-
Urgent need to urinate
-
Blood in the urine
-
Cloudy or foul-smelling urine
-
Nausea
-
Vomiting
-
Fatigue
-
Weakness
Patients may experience both urinary symptoms and signs of a systemic infection.
Risk Factors
The risk of a kidney infection is higher in people with:
-
Recurrent urinary tract infections
-
Kidney stones
-
Urinary tract obstruction
-
Enlarged prostate
-
Diabetes
-
Pregnancy
-
Weakened immune system
-
Structural abnormalities of the urinary tract
-
Long-term urinary catheter use
Managing these conditions can reduce the risk of recurrent infections.
Possible Complications
If untreated, a kidney infection may lead to:
-
Kidney abscess
-
Permanent kidney scarring
-
Reduced kidney function
-
Chronic kidney disease
-
Bloodstream infection (sepsis)
-
Recurrent kidney infections
Prompt treatment significantly reduces these risks.
How Is a Kidney Infection Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a thorough evaluation.
Medical History and Physical Examination
Your doctor reviews:
-
Urinary symptoms
-
Fever
-
Pain location
-
Medical history
-
Previous UTIs
-
Kidney stone history
-
Current medications
Urine Tests
Important investigations include:
-
Routine Urinalysis
-
Urine Microscopy
-
Urine Culture and Sensitivity
-
Protein Estimation when indicated
These tests identify bacteria, infection, blood, and other abnormalities.
Blood Tests
Investigations may include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Complete Blood Count (CBC)
-
Electrolytes
These tests help evaluate kidney function and the severity of infection.
Imaging Studies
If clinically indicated, imaging may include:
-
Kidney Ultrasound
-
CT Scan
Imaging helps detect kidney stones, obstruction, abscesses, or structural abnormalities.
Treatment for UTI Affecting the Kidneys
Treatment depends on the severity of the infection.
Antibiotics
Kidney infections are usually treated with antibiotics selected according to:
-
Clinical assessment
-
Urine culture results
-
Severity of infection
Completing the full course of treatment is essential.
Hydration
Maintaining adequate hydration may help support recovery unless fluid intake is medically restricted because of kidney disease or heart disease.
Pain and Fever Management
Your doctor may recommend medications to relieve fever and discomfort.
Patients with kidney disease should avoid taking medicines without medical advice.
Hospital Care
Some patients may require hospitalization, especially if they have:
-
Severe infection
-
Persistent vomiting
-
Sepsis
-
Pregnancy
-
Advanced kidney disease
-
Significant dehydration
Treat the Underlying Cause
If kidney stones, urinary obstruction, or structural abnormalities are present, additional treatment may be necessary to prevent recurrent infections.
