If you are experiencing kidney pain, urinary discomfort or severe flank pain, you may be unsure whether your symptoms are caused by kidney stones vs kidney infection. Although both conditions can cause back or side pain, nausea and urinary changes, their causes are different. Kidney stones are hard mineral deposits that can move through the urinary tract, while a kidney infection is usually caused by bacteria reaching the kidneys.
Understanding the difference between kidney stones and kidney infection can help you recognize important warning signs and seek appropriate medical care. Recognizing kidney stone symptoms and kidney infection symptoms can help you seek timely medical care. The Kidney MD offers personalized kidney care, accurate diagnosis and appropriate treatment for kidney-related conditions in El Paso.
Quick Insight: Kidney Stones vs Kidney Infection
The main difference between kidney stones and kidney infection is their cause. Kidney stones are mineral deposits that can block the urinary tract, while a kidney infection is usually caused by bacteria. Both can cause kidney pain but fever, chills and painful urination are more commonly associated with kidney infection symptoms, while severe, sharp or wave-like flank pain and blood in urine are common kidney stone symptoms.
What Are Kidney Stones?
Kidney stones are hard deposits of minerals and salts that form when urine becomes highly concentrated. Small stones may pass without symptoms, while larger stones can lodge in the ureter, causing severe kidney stone pain, urinary obstruction and other kidney stone symptoms.
What Causes Kidney Stones?
The causes of kidney stones can vary from person to person.
Common risk factors include:
- Not drinking enough fluids
- High sodium or animal-protein intake
- High levels of calcium, oxalate or uric acid in urine
- Family history of kidney stones
- Certain medical conditions
- Obesity and metabolic disorders
- Some medications
- Recurrent urinary tract infections, which can contribute to certain stones such as struvite stones
Common Kidney Stone Symptoms
Recognizing kidney stone symptoms early can help you seek timely medical evaluation and reduce the risk of complications.
Typical kidney stone symptoms may include:
- Severe kidney stone flank pain in the back or side
- Pain that may radiate toward the lower abdomen as the stone moves through the ureter
- Blood in urine kidney stones can cause urine to appear pink, red or brown
- Frequent or urgent urination
- Pain or burning during urination
- Nausea or vomiting
- Difficulty passing urine
- Cloudy or foul-smelling urine
Recognizing kidney stone symptoms and understanding the causes of kidney stones can help you seek timely kidney stone diagnosis and treatment, especially when severe pain or urinary obstruction occurs.
What Is a Kidney Infection?
A kidney infection, also called pyelonephritis, is a bacterial infection that affects one or both kidneys. It often develops when bacteria travel from the bladder through the urinary tract to the kidneys. Early treatment can help prevent serious kidney infection complications.
What Causes a Kidney Infection?
The main causes of kidney infection include:
- Bacteria spreading from a bladder infection
- Untreated or recurrent urinary tract infections
- Urinary blockage or obstruction
- Kidney stones that interfere with normal urine flow
- Certain urinary tract conditions
Common Kidney Infection Symptoms
Typical kidney infection symptoms may include:
- Fever and chills
- Persistent pain or tenderness in the back, side or below the ribs
- Frequent or painful urination
- Cloudy, dark, bloody or foul-smelling urine
- Nausea or vomiting
- Feeling tired or generally unwell
Because some kidney infection symptoms can overlap with kidney stone symptoms, proper medical evaluation is important for identifying the underlying condition and choosing the right treatment.
Kidney Stones vs Kidney Infection: Key Differences
The most important kidney stones vs kidney infection symptoms difference is the underlying cause. Kidney stones develop from mineral deposits, whereas a kidney infection is usually caused by bacteria. Their symptoms may overlap but certain patterns can provide useful clues.
| Category | Kidney Stones | Kidney Infection |
|---|---|---|
| Condition | Mineral deposits that form inside the kidneys | Infection affecting one or both kidneys |
| Causes | Dehydration, mineral buildup, diet, genetics and certain medical conditions | Usually bacteria spreading from the bladder or urinary tract |
| Pain | Pattern: Often severe, sharp and wave-like | Pattern: Often persistent or aching |
| Pain Location | Location: Side or back; may radiate toward the abdomen | Location: Back, side or below the ribs |
| Fever & Chills | Fever: Usually absent unless infection is present Chills: Uncommon without infection | Fever: Common Chills: Common |
| Urinary Symptoms | Blood: Common Painful urination: May occur Frequency: May increase | Blood: May occur Painful urination: Common Frequency: Common |
| Urine Changes | Blood, cloudy urine or unusual odor may occur | Cloudy, dark, bloody or foul-smelling urine may occur |
| Digestive Symptoms | Nausea/vomiting: Common with severe kidney stone pain | Nausea/vomiting: May occur with infection |
| Diagnosis | Urinalysis, blood tests, CT scan, ultrasound or other imaging | Urinalysis, urine culture, blood tests and imaging when needed |
| Treatment | Approach: Depends on stone size, location and severity; medication or stone removal may be needed | Approach: Usually antibiotics; additional treatment may be needed for complications |
Understanding kidney stones vs kidney infection and the difference between kidney stones and kidney infection is particularly important when symptoms include fever or chills. A suspected stone accompanied by infection symptoms should not be ignored and should be medically evaluated.
How Can You Tell If You Have Kidney Stones or Kidney Infection?
Symptoms can provide clues but they cannot confirm whether you have kidney stones or kidney infection. Severe, wave-like flank pain may suggest a stone, while fever, chills and urinary symptoms may suggest an infection. Urine tests, blood tests and imaging may be needed to determine the cause accurately.
Can Kidney Stones Cause a Kidney Infection?
Yes, kidney stones causing infection is possible, particularly when a stone blocks the normal flow of urine. A blocked urinary tract can create conditions that increase the risk of urinary infection.Untreated kidney stones can cause urinary tract infections, including kidney infections, particularly when they obstruct the normal flow of urine.
This makes kidney infection from kidney stones an important concern. If you have kidney stone symptoms along with fever, chills, vomiting or difficulty passing urine, seek prompt medical evaluation, as these symptoms may indicate an infection or urinary obstruction.

Do Kidney Stones Cause Fever?
An uncomplicated kidney stone does not typically cause fever. When fever and kidney stones occur together, it may indicate an infection, especially if you also have chills, painful urination, vomiting, or feel seriously unwell. If you are concerned about kidney stones or kidney infection, it is advisable to seek medical evaluation rather than assuming the fever is caused by the kidney stone.
What Happens If Kidney Stones or Kidney Infection Are Left Untreated?
Untreated kidney stone complications can include urinary obstruction, recurrent urinary infections, severe pain and loss of kidney function in some cases. Early evaluation can help reduce the risk of these problems.
Untreated kidney infection complications can be more serious. Infection can spread beyond the urinary system and, in uncommon cases, lead to sepsis, which can be life-threatening.
What Can Be Mistaken for Kidney Stones or Kidney Infection?
Several conditions can cause symptoms similar to kidney stones vs kidney infection symptoms, including:
- Urinary tract infections (UTIs)
- Appendicitis
- Gallstones
- Muscle strain
- Gastrointestinal conditions
- Other urinary tract problems
Because symptoms can overlap, severe back or abdominal pain does not always indicate kidney stones and urinary discomfort does not necessarily mean a kidney infection.
Proper kidney stone diagnosis and kidney infection diagnosis can help identify the underlying cause.
How to Reduce Your Risk of Kidney Stones and Kidney Infection
Prevention for kidney stones vs kidney infection depends on the underlying cause and your individual risk factors.
Helpful steps include:
Kidney Stone Prevention
- Stay hydrated: Drink enough fluids to maintain healthy urine output.
- Limit excess sodium: High sodium intake can increase the risk of some kidney stones.
- Follow a balanced diet: Dietary changes may depend on your specific stone type.
- Maintain a healthy weight: A healthy lifestyle may help reduce kidney stone risk.
- Follow medical advice: If you have recurrent kidney stones, a nephrologist may recommend specific dietary or medication changes based on your individual risk factors.
Kidney Infection Prevention

- Follow prescribed treatment: Complete antibiotics exactly as directed by your nephrologist.
- Address urinary problems: Conditions that interfere with normal urine flow may increase infection risk.
- Manage recurrent infections: Discuss recurring urinary symptoms with a healthcare professional.
- Seek timely care: Fever, chills, painful urination or flank pain may require medical evaluation for kidney infection symptoms.
Taking preventive steps and recognizing early kidney stones vs kidney infection symptoms can help reduce complications and support better long-term kidney health.
