Introduction
A ureteral stent infection is a potential complication that can occur after placement of a ureteral stent. A ureteral stent is a thin tube inserted into the ureter to help urine flow from the kidney to the bladder. Stents are commonly used after kidney stone treatment, ureteral obstruction, urinary tract surgery, or other kidney and urinary tract procedures.
While ureteral stents are often lifesaving and help preserve kidney function, they can sometimes increase the risk of urinary tract infections (UTIs), bacterial colonization, discomfort, and urinary symptoms. Prompt diagnosis and appropriate treatment are essential because untreated infections may spread to the kidneys or bloodstream.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, infection-related kidney assessment, personalized treatment plans, kidney stone management, dialysis guidance, kidney transplant evaluation, and long-term kidney care.
What Is a Ureteral Stent?
A ureteral stent is a flexible tube placed between the kidney and bladder.
Its purpose is to:
-
Relieve urinary obstruction
-
Improve urine drainage
-
Protect the ureter after surgery
-
Allow healing
-
Prevent kidney swelling
Stents are usually temporary and are removed or replaced when appropriate.
Can a Ureteral Stent Cause Infection?
Yes. A ureteral stent may increase the risk of infection because bacteria can attach to the stent surface and form biofilms, which make infections more difficult to eliminate.
The risk increases with:
-
Prolonged stent placement
-
Diabetes
-
Kidney stones
-
Urinary obstruction
-
Previous urinary infections
-
Weakened immunity
Not all patients with stents develop infections.
Symptoms of a Ureteral Stent Infection
Common symptoms include:
-
Fever
-
Chills
-
Burning during urination
-
Frequent urination
-
Urgency to urinate
-
Cloudy urine
-
Foul-smelling urine
-
Blood in the urine
-
Flank pain
-
Lower abdominal discomfort
-
Nausea and vomiting
Severe infection may cause:
-
High fever
-
Severe flank pain
-
Confusion
-
Low blood pressure
-
Reduced urine output
These symptoms require urgent medical attention.
Causes of Ureteral Stent Infection
Bacterial Contamination
Bacteria may enter the urinary tract during or after stent placement.
Biofilm Formation
Microorganisms can attach to the stent and become resistant to eradication.
Prolonged Stent Retention
Stents left in place longer than recommended have a higher infection risk.
Urinary Obstruction
Persistent obstruction may promote bacterial growth.
Kidney Stones
Stones can harbor bacteria and contribute to recurrent infections.
How Is a Ureteral Stent Infection Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a detailed evaluation.
Medical History and Examination
The doctor evaluates:
-
Fever
-
Urinary symptoms
-
Flank pain
-
Stent placement history
-
Kidney stone history
-
Medical conditions
Urine Tests
Investigations may include:
-
Routine urinalysis
-
Urine culture
-
Urine microscopy
Urine culture is important for selecting the most effective antibiotic.
Blood Tests
Investigations may include:
-
Complete Blood Count (CBC)
-
Serum creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Electrolytes
-
Blood cultures when indicated
These tests assess infection severity and kidney function.
Imaging Studies
Imaging may include:
-
Kidney ultrasound
-
CT scan when required
These help identify:
-
Persistent obstruction
-
Kidney swelling
-
Residual stones
-
Stent position
-
Kidney infection
Ureteral Stent Infection Treatment
Treatment depends on the severity of infection and kidney function.
Antibiotics
Appropriate antibiotics are the primary treatment for bacterial infection.
The choice of antibiotic is guided by:
-
Urine culture results
-
Kidney function
-
Infection severity
-
Previous antibiotic exposure
Completing the full course of antibiotics is essential.
Intravenous Antibiotics
Hospital treatment with intravenous antibiotics may be required for:
-
High fever
-
Kidney infection
-
Sepsis
-
Vomiting
-
Severe pain
-
Reduced kidney function
Stent Removal or Replacement
In some patients, the stent may need to be:
-
Removed
-
Replaced
-
Repositioned
This is particularly important when the stent is heavily colonized or has been in place for an extended period.
Relief of Urinary Obstruction
If obstruction persists, restoring urine drainage is essential for infection control.
Pain Management
Medications may be prescribed to reduce:
-
Flank pain
-
Bladder discomfort
-
Urinary urgency
Can the Infection Damage the Kidneys?
Yes. Untreated stent-related infections may lead to:
-
Kidney infection (pyelonephritis)
-
Kidney abscess
-
Acute kidney injury
-
Reduced kidney function
-
Sepsis
-
Permanent kidney damage in severe cases
Early treatment greatly reduces these risks.
How Long Does Treatment Take?
Recovery depends on:
-
Infection severity
-
Bacterial organism
-
Kidney function
-
Presence of obstruction
-
Need for stent replacement
Mild infections may improve within a few days of appropriate antibiotics, while severe infections may require hospitalization.
Preventing Ureteral Stent Infections
Patients can reduce infection risk by:
-
Following medical advice
-
Taking prescribed medications
-
Drinking adequate fluids as advised
-
Maintaining good hygiene
-
Reporting fever promptly
-
Attending scheduled follow-up appointments
-
Ensuring timely stent removal or replacement
Never keep a ureteral stent longer than recommended.
When Should You Seek Immediate Medical Care?
Seek urgent medical attention if you have:
-
Fever after stent placement
-
Chills
-
Severe flank pain
-
Persistent vomiting
-
Reduced urine output
-
Confusion
-
High blood pressure with kidney symptoms
-
Signs of sepsis
These symptoms require prompt evaluation.
