Can Kidney Stone Cause Kidney Failure?
Yes, a kidney stone can cause kidney failure, but this is uncommon when the stone is diagnosed and treated on time. Most kidney stones do not permanently damage the kidney. The risk increases when a stone blocks urine flow, causes infection, affects both kidneys, blocks the only working kidney, or remains untreated for a long time. In these situations, creatinine can rise and kidney function can fall. Fever with kidney stone pain is especially serious because an infected blocked kidney may need urgent drainage with a DJ stent or nephrostomy tube. Kidney stones rarely cause permanent damage when treated by a healthcare professional.
Can Kidney Stone Cause Kidney Failure?
A kidney stone can cause kidney failure mainly by blocking urine flow.
Your kidneys make urine continuously. Urine normally passes from the kidney into a thin tube called the ureter, then into the urinary bladder. If a stone gets stuck in the ureter, urine may collect behind the blockage. This causes kidney swelling, called hydronephrosis.
A short blockage may recover well after treatment. But a severe, infected, repeated or long-standing blockage can reduce kidney function. The European Association of Urology describes infected obstruction or anuria – no urine output – as a urological emergency because urgent drainage may be needed.
Kidney Damage vs Kidney Failure: What Is the Difference?
Patients often say, “My kidney is failing,” when they see hydronephrosis or high creatinine on a report. But kidney swelling, kidney damage and kidney failure are not the same.
| Term | Meaning | Example in kidney stone disease |
|---|---|---|
| Kidney swelling | Urine is collecting behind a blockage | Hydronephrosis due to ureter stone |
| Kidney damage | One kidney may lose some function | Long-standing silent obstruction |
| Acute kidney injury | Kidney function drops suddenly | Creatinine rises due to obstruction, dehydration or sepsis |
| Chronic kidney disease | Long-term reduced kidney function | Recurrent stones, infection, diabetes or hypertension |
| Kidney failure | Severe loss of kidney function | Rare, but possible with both kidneys blocked, single kidney obstruction or severe infection |
So, a kidney stone does not automatically mean kidney failure. But a blocked stone can become dangerous if ignored.
Does Every Kidney Stone Damage the Kidney?
No. Most kidney stones do not cause kidney failure.
Many small stones pass naturally. Some stones remain inside the kidney without blocking urine. These may need observation, repeat imaging or planned treatment depending on size, symptoms, infection risk and kidney function.
The important point is this: a stone is not judged only by size. A small stone stuck in the ureter can be more urgent than a larger stone sitting quietly inside the kidney.
When Can a Kidney Stone Become Dangerous?
The risk depends on stone location, blockage, infection, kidney reserve and how quickly treatment is started.
| Situation | Risk to kidney function | Urgency |
|---|---|---|
| Small non-blocking kidney stone | Low | Routine follow-up |
| Ureter stone with severe pain | Moderate | Early urology visit |
| Stone with persistent vomiting | Moderate to high | Same-day evaluation |
| Stone with fever or chills | High | Emergency |
| Stone in a single functioning kidney | High | Urgent |
| Stones blocking both kidneys | Very high | Emergency |
| Long-standing silent obstruction | High | Early treatment |
| Stone with high creatinine | High | Urgent urology evaluation |
How Can a Stone Cause Creatinine to Rise?
Creatinine is a blood test used to estimate kidney function. A high creatinine does not always mean permanent kidney failure, but it should never be ignored in a patient with kidney stone disease.
Creatinine may rise due to:
- Blockage of both kidneys
- Blockage of a single functioning kidney
- Severe dehydration from vomiting
- Infection or sepsis
- Pre-existing chronic kidney disease
- Diabetes, hypertension or older age
- Long-standing obstruction
A very important point: normal creatinine does not always mean the blocked kidney is safe. If only one kidney is blocked and the other kidney is working well, the blood creatinine may still remain normal because the other kidney is compensating. Imaging is needed to check whether one kidney is swollen or obstructed.
Can Kidney Stone Lead to Dialysis?
Usually, no. Dialysis due to kidney stones is rare.
But it can happen in serious situations, such as:
- Both kidneys are blocked
- The patient has only one functioning kidney
- There is severe infection or sepsis
- The patient already has chronic kidney disease
- Treatment is delayed for a long time
- Severe vomiting and dehydration worsen kidney injury
The goal of early urology care is to treat the stone before the situation reaches this stage.
Fever With Kidney Stone Pain Is an Emergency
This is the most important warning sign.
A blocked kidney with infection can become life-threatening. Antibiotics alone may not be enough if infected urine is trapped behind a stone. The kidney may need urgent drainage.
Drainage can be done by:
- DJ stent: a thin tube placed from kidney to bladder
- Percutaneous nephrostomy: a tube placed through the back directly into the kidney
EAU guidelines state that an obstructed kidney with infection signs or no urine output is a urological emergency, and urgent decompression is often needed to prevent complications.
Warning Signs: When to Seek Urgent Care
Do not wait at home if kidney stone pain is associated with:
- Fever, chills or shivering
- Vomiting that prevents drinking fluids
- Reduced urine output
- Severe pain not controlled with medicines
- Burning urination with fever
- Drowsiness, confusion or low blood pressure
- Known single kidney
- Pregnancy with stone pain
- High creatinine
- Known chronic kidney disease
- Stone pain on both sides
These symptoms need prompt medical evaluation. Fever with stone pain should be treated as an emergency.
How Do Doctors Check If a Stone Is Affecting Kidney Function?
A urologist may advise tests based on pain, fever, stone size, obstruction and kidney function.
Urine tests
Urine routine and microscopy can show blood, pus cells, crystals or infection. A urine culture helps choose the correct antibiotic when infection is suspected.
Blood tests
Serum creatinine and eGFR help estimate kidney function. CBC may show infection. Electrolytes may be needed if creatinine is high, urine output is reduced or admission is required.
Ultrasound KUB
Ultrasound can show hydronephrosis, large stones, bladder urine retention and kidney swelling. It is often used as an initial test, especially in pregnancy, children and patients needing quick screening.
CT KUB
A plain CT KUB helps confirm stone size, location, number and degree of obstruction. NICE recommends urgent low-dose non-contrast CT within 24 hours for adults with suspected renal colic, while ultrasound is preferred first in pregnancy and children.
Kidney function scan
In selected long-standing or silent obstruction cases, a DTPA or EC renal scan may be advised to measure how much function each kidney has.
Can Kidney Function Recover After Stone Treatment?
Often, yes.
If the blockage is recent and treated early, kidney function may improve after the stone passes, after DJ stenting, after nephrostomy drainage or after stone removal.
Recovery depends on:
- How long the kidney was blocked
- Whether infection was present
- Whether one or both kidneys were affected
- Whether the patient has diabetes or hypertension
- Baseline kidney function
- Age and hydration status
- Recurrent stone history
Long-standing obstruction may not recover completely, even after the stone is removed. That is why follow-up imaging matters.
Treatment Options When Kidney Function Is at Risk
Treatment depends on stone size, location, pain, infection, creatinine and kidney function.
Observation and medicines
Small stones may pass naturally with fluids, pain control and selected medicines. This is considered only when pain is controlled, there is no fever, kidney function is stable and follow-up is reliable.
DJ stenting
A DJ stent is a thin tube placed from the kidney to the bladder. It bypasses the blockage and allows urine to drain.
Percutaneous nephrostomy
A nephrostomy is a tube placed through the back directly into the kidney. It may be needed when urgent drainage is required or stenting is difficult.
URSL or RIRS
Ureteroscopy or RIRS uses a small camera through the urinary passage to break and remove stones. These are commonly planned after infection is controlled.
PCNL
PCNL is used for large kidney stones or staghorn stones. It removes stones through a small tract made from the back.
Are Recurrent Kidney Stones Linked to Long-Term Kidney Disease?
Recurrent kidney stones may increase the long-term risk of chronic kidney disease, especially when stones are associated with repeated infection, obstruction, diabetes, hypertension, uric acid stones, cystine stones or anatomical urinary tract problems.
A meta-analysis found that people with a history of kidney stones had a higher adjusted risk of chronic kidney disease compared with people without stones. This does not mean every stone patient will develop CKD, but it supports prevention, follow-up and metabolic evaluation in selected patients.
How to Reduce the Risk of Kidney Damage From Stones
You can reduce risk by:
- Not ignoring severe stone pain
- Getting imaging if pain recurs
- Checking creatinine when advised
- Treating fever with stone pain as urgent
- Completing follow-up after stone treatment
- Doing stone analysis if a stone is retrieved
- Preventing recurrence with diet and metabolic evaluation when needed
- Managing diabetes, BP and obesity
- Drinking adequate fluids unless restricted by your doctor

FAQs
1. Can kidney stone cause kidney failure?
Yes, but it is uncommon. The risk is higher when a stone blocks urine flow, causes infection, affects both kidneys, blocks a single functioning kidney or remains untreated for a long time.
2. Can kidney stone increase creatinine?
Yes. Creatinine can rise if the stone blocks both kidneys, blocks the only working kidney, causes severe infection or causes dehydration due to vomiting.
3. Does high creatinine mean permanent kidney failure?
Not always. Creatinine may rise temporarily due to obstruction, dehydration or infection. But high creatinine with a kidney stone needs urgent medical evaluation.
4. Can normal creatinine still hide kidney damage?
Yes. If one kidney is blocked but the other kidney is normal, creatinine may remain normal. Imaging is needed to check whether one kidney is swollen or obstructed.
5. I have only one kidney and a kidney stone. Is it urgent?
Yes. A stone blocking the only working kidney can quickly affect urine output and creatinine. Seek urgent urology evaluation, especially if there is pain, fever, vomiting or reduced urine.
6. Can one kidney stone cause dialysis?
Usually no. Dialysis is rare. It may be needed in severe cases such as both kidneys blocked, single kidney obstruction, sepsis or pre-existing chronic kidney disease.
7. Can hydronephrosis damage the kidney?
Yes, if it is severe, infected or long-standing. Mild short-term hydronephrosis may recover after treatment, but it needs follow-up.
8. Can kidney stones silently damage the kidney?
Yes. Some stones may cause silent obstruction without severe pain. This is one reason follow-up imaging is important for known stones.
9. What is the most dangerous symptom with kidney stone?
Fever with kidney stone pain is the most dangerous warning sign. It may mean infected obstruction, which can become life-threatening without urgent treatment.
10. Should I wait for a stone to pass if creatinine is high?
No. High creatinine with a kidney stone needs prompt urology evaluation. Waiting at home can be risky, especially if there is fever, reduced urine output or a single kidney.
