Introduction
Many people wonder whether kidney stones can cause a urinary tract infection (UTI). The answer is yes. Kidney stones can increase the risk of UTIs by blocking the normal flow of urine and creating an environment where bacteria can grow.
A urinary tract infection associated with a kidney stone requires prompt medical attention because it can become a serious condition if left untreated. In some cases, the infection may spread to the kidneys, leading to a kidney infection (pyelonephritis) or even a life-threatening bloodstream infection.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive evaluation, advanced diagnostic testing, kidney stone management, UTI treatment, dialysis planning, kidney transplant evaluation, and long-term kidney care.
Can Kidney Stones Cause a UTI?
Yes.
Kidney stones can contribute to urinary tract infections by:
-
Blocking the normal flow of urine
-
Preventing complete emptying of the urinary tract
-
Allowing bacteria to multiply
-
Irritating the lining of the urinary tract
-
Causing urine to remain trapped behind the blockage
When bacteria grow in stagnant urine, the risk of infection increases significantly.
How Do Kidney Stones Lead to Infection?
Normally, urine flows continuously from the kidneys to the bladder, helping remove bacteria from the urinary tract.
A kidney stone may:
-
Obstruct urine flow
-
Trap bacteria
-
Delay urine drainage
-
Increase pressure inside the kidney
These conditions make bacterial infection more likely.
Symptoms of Kidney Stones
Common symptoms include:
-
Severe pain in the back or side (flank pain)
-
Pain radiating toward the groin
-
Blood in the urine
-
Frequent urination
-
Pain while urinating
-
Nausea and vomiting
-
Difficulty passing urine
The severity of pain depends on the size and location of the stone.
Symptoms of a UTI
A urinary tract infection may cause:
-
Burning during urination
-
Frequent urge to urinate
-
Passing small amounts of urine
-
Cloudy urine
-
Foul-smelling urine
-
Blood in the urine
-
Lower abdominal discomfort
If the infection spreads to the kidneys, symptoms may become more severe.
Symptoms of a Kidney Infection
When bacteria reach the kidneys, symptoms may include:
-
Fever
-
Chills
-
Severe flank pain
-
Nausea
-
Vomiting
-
Weakness
-
Fatigue
A kidney infection associated with a kidney stone is considered a medical emergency and requires urgent treatment.
Risk Factors
The risk of developing a UTI with kidney stones is higher in people who have:
-
Large kidney stones
-
Recurrent kidney stones
-
Diabetes
-
Urinary tract obstruction
-
Enlarged prostate
-
Weakened immune system
-
Previous urinary tract infections
-
Poor fluid intake
Early treatment helps reduce the risk of complications.
When Should You See a Nephrologist?
Consult a nephrologist if you have:
-
Kidney stone symptoms
-
Recurrent UTIs
-
Fever with kidney stone pain
-
Blood in the urine
-
High creatinine levels
-
Reduced eGFR
-
Persistent urinary symptoms
-
Difficulty passing urine
Immediate medical attention is needed if fever occurs along with severe flank pain and a known kidney stone.
How Are Kidney Stones and UTIs Diagnosed?
At Prabhakar Bhurke Clinic, our super specialist nephrologist performs a comprehensive kidney evaluation.
Medical History and Physical Examination
The doctor reviews:
-
Pain location
-
Urinary symptoms
-
Previous kidney stones
-
History of UTIs
-
Medical conditions
-
Current medications
Urine Tests
Investigations may include:
-
Urinalysis
-
Urine Culture
-
Urine Microscopy
-
Protein Testing
These tests help identify infection and guide treatment.
Blood Tests
Important investigations include:
-
Serum Creatinine
-
Estimated Glomerular Filtration Rate (eGFR)
-
Blood Urea Nitrogen (BUN)
-
Complete Blood Count (CBC)
-
Electrolytes
These tests assess kidney function and infection severity.
Imaging Studies
Depending on your condition, investigations may include:
-
Kidney Ultrasound
-
CT Scan
-
X-ray (KUB) when appropriate
Imaging helps identify kidney stones, urinary obstruction, hydronephrosis, or structural abnormalities.
Treatment for Kidney Stones and UTI
Treatment depends on the severity of both the stone and the infection.
Antibiotics
Bacterial urinary tract infections require appropriate antibiotics based on clinical evaluation and, when available, urine culture results.
Pain Management
Medications may be recommended to relieve pain and improve comfort.
Hydration
Adequate fluid intake may help maintain urinary flow unless fluid restriction is medically advised.
Kidney Stone Treatment
Depending on the stone's size and location, treatment may include:
-
Observation for small stones
-
Medical therapy
-
Extracorporeal Shock Wave Lithotripsy (ESWL)
-
Ureteroscopy (URS)
-
Retrograde Intrarenal Surgery (RIRS)
-
Percutaneous Nephrolithotomy (PCNL)
The choice of treatment is individualized.
Relieving Urinary Obstruction
If a stone causes significant blockage with infection, urgent drainage procedures may be required before definitive stone removal.
Possible Complications
Without timely treatment, kidney stones associated with infection may lead to:
-
Kidney infection (Pyelonephritis)
-
Kidney abscess
-
Kidney damage
-
Sepsis
-
Chronic kidney disease
-
Recurrent urinary tract infections
Early diagnosis significantly reduces these risks.
How to Prevent Kidney Stones and UTIs
Reduce your risk by:
-
Drinking adequate water.

Frequently Asked Questions (FAQs)
Can kidney stones cause a urinary tract infection?
Yes. Kidney stones can block urine flow and increase bacterial growth, making UTIs more likely.
