Introduction

An infected kidney stone is a serious condition where a kidney stone is associated with a urinary tract infection or kidney infection. Unlike simple kidney stones, infected stones can block urine flow and allow bacteria to multiply, increasing the risk of severe complications.

Early diagnosis and proper infected kidney stone treatment are essential to control infection, relieve obstruction, protect kidney function, and prevent serious health problems.

Treatment usually involves a combination of infection control, relieving urinary blockage, and removing the stone when it is safe to do so.

At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney stone evaluation, advanced diagnostic testing, infection management, personalized treatment plans, kidney function monitoring, and long-term kidney care.

What Is an Infected Kidney Stone?

An infected kidney stone occurs when bacteria are present along with a stone inside the urinary system.

A kidney stone can:

Block urine drainage
Cause urine to accumulate in the kidney
Promote bacterial growth
Increase the risk of kidney infection

An infected obstructing kidney stone may become a medical emergency and requires prompt treatment.

Causes of Infected Kidney Stones

Several factors can contribute to infected kidney stones.

Urinary Tract Infection (UTI)

A urinary infection can occur along with a kidney stone and may worsen if urine flow is blocked.

Urinary Obstruction

A stone blocking the ureter can prevent urine from draining properly, creating an environment where bacteria multiply.

Recurrent Kidney Stones

Repeated stone formation increases the risk of infections and kidney damage.

Struvite Stones

Certain stones, called infection stones or struvite stones, develop due to specific bacterial infections.

Reduced Immunity

Patients with diabetes, chronic illnesses, or weakened immunity may have a higher risk of infected stones.

Symptoms of an Infected Kidney Stone

Symptoms may include:

Severe Flank or Back Pain

Pain may occur on one side of the back below the ribs and may radiate toward the abdomen or groin.

Fever and Chills

Fever with kidney stone symptoms may indicate an active infection.

Burning During Urination

Patients may experience pain or discomfort while passing urine.

Frequent Urination

Infection and irritation may increase urinary frequency.

Cloudy or Foul-Smelling Urine

Changes in urine appearance or smell may suggest infection.

Blood in Urine

A stone can irritate the urinary tract and cause bleeding.

Nausea and Vomiting

Severe pain and infection may cause digestive symptoms.

Reduced Urine Output

A blockage may reduce urine flow and affect kidney function.

Is an Infected Kidney Stone Dangerous?

Yes. An infected kidney stone can become dangerous if left untreated.

Possible complications include:

Severe kidney infection
Blood infection (sepsis)
Kidney damage
Reduced kidney function
Emergency hospitalization

A blocked infected kidney requires urgent medical attention.

Medical History and Physical Examination

The doctor evaluates:

Pain location and severity
Fever history
Urinary symptoms
Previous kidney stones
Medical conditions
Current medications

Blood Tests

Investigations may include:

Serum Creatinine
Kidney Function Tests
Complete Blood Count (CBC)
Electrolytes
Inflammatory markers when required

These tests assess infection severity and kidney function.

Urine Tests

Urine testing helps detect:

Bacteria
Infection
Blood
Protein
Urinary abnormalities

Tests may include:

Urinalysis
Urine culture

Imaging Tests

Imaging helps identify:

Stone size
Stone location
Kidney swelling
Urinary obstruction

Common tests include:

Kidney ultrasound
Non-contrast CT scan

Infected Kidney Stone Treatment Options

Treatment depends on infection severity, stone size, location, and kidney function.

Antibiotic Treatment

Antibiotics are used to control bacterial infection.

The choice of antibiotic depends on:

Type of bacteria
Urine culture results
Patient health condition

Antibiotics should only be taken under medical supervision.

Urgent Drainage of Blocked Kidney

If an infected stone blocks urine flow, immediate drainage may be required.

Common drainage procedures include:

Ureteral Stent Placement

A small tube is placed inside the ureter to allow urine drainage.

Percutaneous Nephrostomy (PCN)

A tube is placed directly into the kidney to drain infected urine.

Stone Removal After Infection Control

The stone is usually treated after the infection is controlled.

Treatment options may include:

Ureteroscopy with Laser Lithotripsy

A scope is passed through the urinary passage, and laser energy breaks the stone.

RIRS (Retrograde Intrarenal Surgery)

A flexible scope is used to treat stones inside the kidney.

PCNL (Percutaneous Nephrolithotomy)

PCNL is commonly used for:

Large kidney stones
Complex stones
Multiple stones

ESWL (Shock Wave Lithotripsy)

Selected stones may be treated using external shock waves.

Recovery After Infected Kidney Stone Treatment

Recovery depends on the infection severity and treatment procedure.

Patients are advised to:

Complete prescribed antibiotics
Drink fluids as recommended
Attend follow-up appointments
Monitor urine symptoms
Follow kidney stone prevention advice

Regular monitoring helps prevent recurrence.
