Introduction
A kidney stone attack can cause sudden, intense pain and may develop when a stone moves from the kidney into the ureter. The pain can be severe because the ureter may spasm around the stone and urine flow can become partially or completely blocked.
Recognizing kidney stone attack symptoms is important because not every episode of severe back or abdominal pain is caused by a kidney stone. Kidney stones can also occur without symptoms, particularly when they remain within the kidney and do not obstruct urine flow.
The severity of symptoms depends on factors such as the stone's size, location, movement, degree of obstruction, and whether an infection is present.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides kidney evaluation, assessment of recurrent stones, kidney-function monitoring, metabolic evaluation, preventive guidance, and coordination with urology specialists when stone removal is required.
What Does a Kidney Stone Attack Feel Like?
A typical kidney stone attack, also called renal colic, often causes sudden pain in the flank or side of the back.
The pain may:
-
Begin suddenly
-
Become severe
-
Come in waves
-
Move from the back toward the abdomen
-
Radiate toward the lower abdomen or groin
-
Make it difficult to remain still
Unlike some types of muscular back pain, renal colic often causes intense discomfort that does not improve simply by changing position.
Main Kidney Stone Attack Symptoms
Severe Flank Pain
One of the most characteristic symptoms is intense pain on one side of the back or below the ribs.
The pain may fluctuate in severity as the stone moves through the ureter.
Pain Radiating to the Groin
As a stone travels down the ureter, discomfort may move toward:
-
Lower abdomen
-
Pelvis
-
Groin
In men, pain may sometimes extend toward the testicle.
Blood in the Urine
A moving stone can irritate the urinary tract and cause blood in the urine.
The blood may be visible or detectable only through urine testing.
Nausea and Vomiting
Severe renal colic can activate nerve pathways that also trigger nausea and vomiting.
Burning During Urination
A stone closer to the bladder may produce burning or discomfort while urinating.
Frequent or Urgent Urination
When a stone reaches the lower ureter near the bladder, a person may feel the need to urinate frequently or urgently.
Difficulty Passing Urine
A stone causing significant obstruction may make urination difficult or reduce urine output.
Sweating and Restlessness
Severe renal colic can cause sweating and make it difficult to find a comfortable position.
Kidney Stone Symptoms Based on Stone Location
Symptoms may change as the stone moves.
Stone Inside the Kidney
Many stones within the kidney produce no symptoms.
Some may cause:
-
Mild flank discomfort
-
Blood in the urine
-
Recurrent urinary problems
Stone in the Upper Ureter
Pain is often felt in the flank or side of the back.
Stone in the Lower Ureter
Pain may move toward the lower abdomen, pelvis, or groin.
Urinary urgency and frequency may become more noticeable.
Stone Near the Bladder
A person may experience:
-
Urinary urgency
-
Frequent urination
-
Burning
-
Lower abdominal discomfort
Kidney Stone Attack vs Back Pain
Kidney stone pain and ordinary back pain can sometimes be confused.
Kidney Stone Pain
It may:
-
Start suddenly
-
Be severe
-
Occur in waves
-
Begin in the flank
-
Radiate toward the abdomen or groin
-
Occur with nausea or vomiting
-
Occur with blood in the urine
Muscle-Related Back Pain
It may:
-
Follow physical activity or injury
-
Become worse with particular movements
-
Improve with rest
-
Be tender when touched
-
Change with posture
These patterns are only clues. Medical evaluation is needed when the diagnosis is uncertain.
What Causes a Kidney Stone Attack?
A kidney stone attack usually occurs when a stone moves into the ureter and interferes with urine flow.
Factors that contribute to stone formation can include:
-
Low fluid intake
-
High urinary concentration of stone-forming substances
-
High dietary sodium intake
-
Certain metabolic conditions
-
Family history
-
Recurrent urinary infections in selected stone types
-
Some medications
-
Certain dietary patterns
-
Previous kidney stones
The chemical composition of the stone also matters.
Common stone types include:
-
Calcium oxalate
-
Calcium phosphate
-
Uric acid
-
Struvite or infection-related stones
-
Cystine stones
Knowing the stone type can help guide prevention.
Warning Signs of a Complicated Kidney Stone Attack
Most kidney stone attacks are painful but not immediately life-threatening. However, some situations require urgent medical care.
Seek urgent medical attention if stone symptoms occur with:
-
Fever
-
Chills
-
Severe weakness
-
Persistent vomiting
-
Difficulty passing urine
-
Very low or no urine output
-
Severe or rapidly worsening pain
-
Known urinary obstruction
-
A single functioning kidney
-
Significant kidney disease
Why Is Fever With an Obstructing Stone Serious?
A blocked urinary tract combined with infection can prevent infected urine from draining properly.
This can become a serious medical emergency and may require:
-
Antibiotics
-
Urgent urinary drainage
-
Urology assessment
-
Hospital-based treatment
Do not rely on home remedies or delay treatment when fever or chills occur with suspected urinary obstruction.
How Are Kidney Stones Diagnosed?
The diagnosis depends on symptoms, physical examination, urine tests, blood tests, and imaging.
Urine Tests
Urinalysis may identify:
-
Blood
-
Infection
-
Crystals
-
Other abnormalities
A urine culture may be recommended when infection is suspected.
Blood Tests
Investigations may include:
-
Serum creatinine
-
eGFR
-
Electrolytes
-
Calcium
-
Uric acid
-
Complete blood count when infection is suspected
These tests help assess kidney function and identify complications.
Ultrasound
Ultrasound can identify many kidney stones and may show hydronephrosis caused by obstruction.
CT Scan
A non-contrast CT scan can provide detailed information about:
-
Stone size
-
Stone location
-
Number of stones
-
Degree of obstruction
-
Urinary tract anatomy
The appropriate imaging test depends on the patient's symptoms and clinical situation.
What Should You Do During a Kidney Stone Attack?
If you suspect a kidney stone:
-
Seek medical evaluation if the pain is severe or persistent.
-
Follow prescribed pain-management advice.
-
Maintain appropriate fluid intake unless your doctor has advised fluid restriction.
-
Do not force large quantities of water rapidly.
-
Watch for fever, chills, vomiting, or reduced urine output.
-
Follow recommended imaging and laboratory tests.
-
Keep any passed stone for analysis if your doctor recommends it.
Drinking excessive amounts of water does not guarantee that a blocked stone will pass and may be unsafe in certain circumstances.
Treatment for a Kidney Stone Attack
Treatment depends on stone size, location, symptoms, kidney function, and the presence or absence of obstruction and infection.
Pain Relief
Pain medication may be prescribed to control renal colic.
Patients with kidney disease should consult a healthcare professional before using NSAID painkillers because these medicines can affect kidney function in certain situations.
Medicines to Help Selected Stones Pass
Some patients with suitable ureteral stones may be offered medical expulsive therapy.
It is not appropriate for every stone, and the decision depends on factors such as stone size, location, symptoms, and clinical findings.
Observation
Selected small stones may pass naturally.
Regular follow-up may be needed to confirm that the stone has passed and that there is no persistent obstruction.
Shock Wave Lithotripsy
SWL or ESWL uses externally generated shock waves to fragment selected kidney or ureteral stones.
Ureteroscopy and Laser Lithotripsy
A urologist can use a small scope passed through the urinary tract to reach the stone. Laser energy can fragment the stone so that pieces can be removed or passed.
RIRS
Retrograde Intrarenal Surgery (RIRS) uses a flexible ureteroscope to access stones within the kidney and fragment them, commonly using a laser.
PCNL
Percutaneous Nephrolithotomy (PCNL) is commonly used for larger or complex kidney stone burdens. The stone is accessed through a small tract into the kidney and fragmented and removed.
Can a Kidney Stone Attack Stop on Its Own?
Yes, some attacks resolve when a small stone passes naturally.
However, pain stopping does not always prove that the stone has passed.
A stone may remain in the urinary tract and continue causing partial obstruction without severe pain.
Follow-up may therefore be recommended to confirm stone passage or resolution of obstruction.
How to Prevent Future Kidney Stone Attacks
After a kidney stone, prevention is important because stones can recur.
General measures may include:
-
Maintain appropriate fluid intake.
-
Reduce excessive salt consumption.
-
Follow a balanced diet.
-
Avoid excessive intake of highly processed foods.
-
Maintain a healthy body weight.
-
Follow individualized dietary advice.
-
Complete metabolic evaluation when stones recur.
The ideal prevention plan depends on the stone's composition and urine chemistry.
Why Recurrent Kidney Stone Attacks Need Specialist Evaluation
Repeated attacks may indicate an underlying metabolic or dietary risk.
A nephrologist may evaluate:
-
Kidney function
-
Urine calcium
-
Urine oxalate
-
Urine citrate
-
Uric acid
-
Sodium excretion
-
Urine volume
-
Blood calcium and uric acid
-
Family history
-
Medication-related risk
Stone analysis can also help determine the appropriate preventive strategy.

Frequently Asked Questions
What is the most common symptom of a kidney stone attack?
Severe flank or side pain is one of the most characteristic symptoms. The pain may come in waves and radiate toward the abdomen or groin.
How long does a kidney stone attack last?
The duration varies. Pain may come in waves as the stone moves, and symptoms can persist until the stone passes or treatment relieves the obstruction.
Can a kidney stone attack happen without blood in the urine?
Yes. Blood in the urine is common but may not occur in every person with a kidney stone.
Can kidney stones cause nausea?
Yes. Severe renal colic commonly causes nausea and can sometimes lead to vomiting.
Is fever normal during a kidney stone attack?
Fever is not something to ignore. Fever or chills with suspected obstruction may indicate a urinary infection and requires prompt medical assessment.
Can drinking water stop a kidney stone attack?
Water does not directly stop renal colic. Appropriate hydration can support urine flow and may help selected small stones pass, but excessive water intake is not a substitute for medical treatment.
Do all kidney stones require surgery?
No. Some small stones pass naturally. Larger, obstructing, persistent, symptomatic, or complicated stones may require active treatment.
Which doctor treats kidney stone attacks?
A nephrologist can evaluate kidney function, metabolic risk factors, and recurrent stone disease. A urologist generally performs procedures used to remove stones or relieve urinary obstruction.
Conclusion
Recognizing kidney stone attack symptoms can help patients seek appropriate care at the right time. Severe flank pain, pain radiating toward the groin, blood in the urine, nausea, vomiting, urinary urgency, and difficulty urinating can occur when a stone moves through the urinary tract.
Most importantly, fever or chills, persistent vomiting, difficulty passing urine, very low urine output, or rapidly worsening pain require prompt medical attention because an obstructed urinary tract with infection can become a medical emergency.
