You’re not alone. About 10% of people will face kidney stones in their lifetime, and roughly 600,000 visit the emergency room each year because of them. Early recognition matters: catching subtle symptoms can keep a small issue from becoming a major health problem.
Stones form when minerals like calcium and oxalate clump, often when you don’t drink enough fluids. A moving kidney stone can block urine flow and cause infection or severe complications. Watch for changes in your urine, new urgency, fever, or shifting pain in your side.
Acting quickly protects your kidneys. If you notice several signs together—even mild pain, burning when you urinate, or blood in urine—seek evaluation. For reliable guidance on symptoms and causes, see this expert overview.
Key Takeaways
- About 10% of people will develop kidney stones; many require emergency care each year.
- Not all cases start with severe pain—look for urine changes, fever, or urgency.
- Early action reduces complications and may avoid invasive treatment.
- Staying hydrated and tracking symptoms helps lower your risk.
- If multiple signs appear, get medical advice promptly to protect your health.
What Kidney Stones Are and How They Form in Your Urinary Tract
Mineral crystals can build up inside your kidneys when urine becomes highly concentrated. Small particles—often calcium combined with oxalate—start as tiny crystals and can join into a larger stone.
Stones range from sand-like grains to sizable masses. As a stone moves from the kidney into the ureter and then the bladder, it can scrape the lining of each part urinary tract and trigger changing symptoms kidney.
Dehydration and a high-salt diet raise your risk. Concentrated urine favors crystallization, while extra water helps flush minerals out before they join together.
“Understanding how stones form helps you catch a troubling sign early and act to protect your health.”
- Small stones may pass unnoticed; larger ones can block urine and cause infections.
- Movement irritates tissue, which produces sharp, shifting pain in your body.
- Adjusting water and salt intake lowers the chance of new stone growth.
| Factor | Effect on stone formation | What you can do |
|---|---|---|
| Low water | Concentrates minerals | Drink more fluids daily |
| High salt | Raises mineral excretion | Cut sodium in meals |
| Mineral balance | Promotes crystallization | Discuss diet and tests with your doctor |
Warning Signs of Kidney Stones
Take note when sudden, severe ache strikes your side or lower back. Renal colic often starts quickly and comes in waves as the ureter contracts, and pain may move toward your belly or groin.
Sudden, severe back or side pain that comes in waves
You may feel sharp, cramping kidney stone pain that rises and falls. This pattern helps clinicians locate a moving stone.
Pain or burning during urination
A burning sensation can mimic a UTI when a stone reaches the bladder or lower tract. Note timing and severity.
Urgent or frequent urination, blood, cloudy urine, or low flow
Frequent trips to the bathroom—especially at night—point to irritation. Seeing blood in your urine or finding it on a test shows lining damage.
Cloudy or foul-smelling urine can mean infection. Passing only small amounts, or a stopped flow, suggests blockage and may be an emergency.
Nausea, vomiting, fever, and chills
Intense stone pain can trigger nausea and vomiting. If fever or chills appear, seek urgent care—this combo can signal an infection that needs prompt treatment.
- Track what you feel and when it occurs to help your clinician pinpoint stone location and severity.
When to Seek Medical Attention for Kidney Stone Symptoms
When pain spikes or your urine looks or flows differently, get medical help quickly. Early evaluation limits complications and speeds care that fits your needs.
Red flags that require urgent or emergency care
Seek medical attention urgently if the pain is so intense you cannot get comfortable. This is a common reason people go to the emergency room.
Treat fever, chills, or a urinary tract infection with a stone as an emergency. Infection plus obstruction can escalate fast.
Also get help if you cannot pass urine, if vomiting prevents hydration, or if you notice heavy blood in your urine.
What to do right now if you suspect a stone
Call your doctor if waves of pain return or urinary changes persist. While waiting for care, sip fluids if you tolerate them and save any stone you pass.
Bring details on when pain peaked and any nausea or vomiting—these clues help guide imaging and tests.
| Urgent sign | Why it matters | Immediate step |
|---|---|---|
| Unrelenting severe pain | May indicate obstruction or large stone | Go to the emergency room for pain control and imaging |
| Fever with suspected stone | Possible infected, obstructed tract | Seek emergency care; this can be a surgical emergency |
| Inability to urinate or heavy blood | Blocked flow or severe injury | Get immediate medical attention; do not delay |
How Kidney Stones Are Diagnosed and Treated
Your doctor will use lab work and imaging to pinpoint a stone and guide care.
Clinical evaluation starts with urine and blood tests to check for blood, infection, and kidney function. Imaging—usually a CT scan or ultrasound—shows size and location in the part urinary tract most affected.
Conservative care you can expect
If a stone is small and not infected, your provider may recommend watchful waiting. Drink more water, take pain medicine, and monitor symptoms. Many stones pass on their own with time and adequate hydration.
Procedures to break or remove stones
- ESWL uses focused sound waves to fragment stones so fragments pass more easily and reduce stone pain.
- Ureteroscopy uses a thin scope via the bladder to reach the ureter; stones are removed with a basket or fragmented by laser.
- Percutaneous nephrolithotomy involves a small back incision for large or complex stones and clears them efficiently.
If an infection is present, it must be treated promptly alongside stone care to protect your kidneys and avoid an emergency. Follow-up imaging confirms clearance and helps prevent recurrence.
“Accurate diagnosis guides the right treatment so you can recover with less pain and fewer repeat episodes.”
Risk Factors You Can Address and How to Prevent Kidney Stones
You can lower your chance of forming painful stones by changing everyday habits that affect urine chemistry. Small, consistent steps help protect your kidney health and reduce the need for medical attention.
Diet, hydration, and lifestyle choices
Prioritize hydration: aim for about 11 cups of total fluids daily from water, fruits, tea, and coffee to keep minerals dilute and ease passage.
Cut back on processed food, added sugar, and excess animal protein. Limit salt to reduce mineral excretion that fosters developing kidney stones.
Keep dietary calcium with meals—this binds oxalate in the gut and can prevent stones without increasing risk.
Medical issues, meds, and family history to review
Talk with your doctor about past urinary tract infections, diabetes, gout, IBD, or a family history of stones. These conditions raise your risk kidney stones and change prevention strategies.
Review medications like calcium-based antacids or some diuretics that may promote stone formation.
Everyday prevention you can start now
- Hydrate regularly and carry a water bottle.
- Check labels for sodium and choose whole foods over processed options.
- If you’ve had stones before, ask for targeted testing and a personalized plan to stop developing kidney stones again.

Conclusion
Swift evaluation can spare you days of severe pain and reduce the chance of infection or complications.
If you notice signs kidney stones—back pain that comes in waves, blood in your urine, burning, or sudden urgency—act now. Severe pain with nausea or vomiting often means a moving stone and needs prompt assessment.
If fever accompanies symptoms kidney stones, treat it as an emergency and contact emergency services or get to the emergency room without delay.
Options range from fluids and pain control to ESWL, ureteroscopy, or percutaneous nephrolithotomy. Talk to your doctor to confirm the cause and set a plan. With quick care and prevention—hydrate, cut excess salt, and balance calcium—you can lower future risk and feel better faster.
FAQ
What should I know if I think you are experiencing warning signs of kidney stones?
If you feel sudden, severe back or side pain that comes in waves, strong pain during urination, or notice blood in your urine, you should treat these as urgent cues. These symptoms often come from a stone moving through your urinary tract and can cause nausea, vomiting, or fever. Contact your healthcare provider or head to the emergency room if pain is intense, urine flow stops, or you have a high fever with chills.
What are kidney stones and how do they form in your urinary tract?
Stones form when minerals like calcium, oxalate, or uric acid concentrate and crystallize in your kidneys or ureter. Low fluid intake, high salt or animal-protein diets, and certain medical conditions raise your risk. Once a stone shifts into the ureter, it can block urine flow and cause the sharp, cramping pain you might feel.
How will I know if the sudden, severe back or side pain is from a stone?
Pain from a stone usually starts abruptly, comes in severe waves, and radiates toward your groin or lower abdomen. It often forces you to move or change positions and can be accompanied by nausea or sweating. If pain peaks quickly and is unrelenting, get medical care to rule out other serious causes.
Could pain or burning during urination mean you have a stone rather than a UTI?
Yes. Stones near the bladder or in the ureter can cause sharp pain or burning that feels like a urinary tract infection. Because signs overlap—cloudy urine, urgency, or frequency—your provider will likely test urine and perform imaging to distinguish a stone from an infection.
Is urgent or frequent need to urinate, especially at night, a common symptom?
Increased urgency and nighttime urination occur when a stone irritates the bladder or lower urinary tract. If you suddenly need to pee more often or wake repeatedly at night, mention it to your clinician—especially if it’s new and accompanied by other symptoms like pain or blood in the urine.
What does blood in my urine indicate and when is it dangerous?
Visible red, pink, or brown urine or microscopic blood on a test usually means a stone is scraping the urinary tract. While small amounts can be managed, heavy bleeding, fainting, or a drop in blood pressure requires immediate evaluation to rule out severe bleeding or complications.
Why would my urine be cloudy or foul-smelling with a stone?
Cloudy or foul urine can suggest infection alongside a stone. If you also have fever or chills, this combination can signal an infected, obstructed kidney—an emergency that needs prompt antibiotics and drainage to prevent sepsis.
What does it mean if you pass only small amounts of urine or your flow stops?
Reduced urine output or inability to urinate may indicate a blockage from a stone. This is urgent, especially when paired with severe pain or fever. Seek emergency care so clinicians can relieve the obstruction and protect your kidney function.
Are nausea and vomiting common and what should you do about them?
Yes. Intense stone pain often triggers nausea and vomiting. Stay hydrated if you can tolerate fluids, but seek medical treatment if you can’t keep liquids down, become dehydrated, or pain is uncontrolled despite home measures.
When do fever and chills mean you need emergency care?
Fever and chills with a suspected stone suggest infection in the urinary tract or kidney. That combination can quickly progress to sepsis. You should get immediate medical attention—call emergency services or go to the ER without delay.
What are the red flags that require urgent or emergency care?
Go to the emergency room if you have severe, uncontrolled pain; high fever with chills; vomiting that prevents fluid intake; little or no urine output; fainting or lightheadedness; or heavy bleeding in your urine. These signs can indicate obstruction, infection, or complications needing immediate treatment.
What should you do right now if you suspect a stone?
Start by drinking water if you can tolerate it, avoid NSAIDs if you have kidney disease unless advised by your doctor, and seek prompt medical evaluation for pain control, urine testing, and imaging. If you have fever, uncontrollable pain, or cannot urinate, go to the nearest emergency department immediately.
How are stones diagnosed through clinical evaluation, urine, blood tests, and imaging?
Providers will check your urine for blood and infection and run blood tests to assess kidney function and infection markers. Non-contrast CT scan is the most accurate imaging to find and size stones; ultrasound may be used for pregnant patients or initial evaluation. These steps guide treatment choice.
When is conservative care like hydration and watchful waiting appropriate?
Small stones (usually under 5–6 mm) often pass with increased fluids, pain control, and anti-nausea medication. Your clinician may recommend medical expulsive therapy in some cases and schedule follow-up imaging to confirm passage. Stay alert for worsening signs that require intervention.
How does extracorporeal shock wave lithotripsy (ESWL) work?
ESWL uses focused sound waves to break stones into smaller fragments that you can pass in urine. It’s noninvasive, suited for certain stone sizes and locations, and typically done outpatient. Your doctor will discuss risks and expected recovery time.
What is ureteroscopy with laser and when is it used?
Ureteroscopy involves a flexible scope passed through the urethra and bladder into the ureter. A laser fragments or vaporizes the stone, and fragments are removed. It’s effective for ureteral stones or stones that won’t pass and provides quick symptom relief.
When is percutaneous nephrolithotomy recommended?
Percutaneous nephrolithotomy is a minimally invasive surgery for large, complex, or stubborn kidney stones. A small incision allows instruments direct access to the kidney to remove stones. Your urologist will recommend this when other treatments are unlikely to succeed.
What diet, hydration, and lifestyle choices lower your risk?
Drink enough water to produce clear or pale urine most of the day. Reduce high-sodium foods and limit excessive animal protein and processed foods. Maintain a balanced calcium intake from food (don’t avoid calcium unless told to) and cut down on high-oxalate items if advised. These changes lower recurrence risk.
Which medical conditions, medications, or family history should you discuss with your doctor?
Tell your clinician about prior stones, kidney disease, gout, inflammatory bowel disease, bariatric surgery, or a family history of stones. Some medications and supplements can increase risk. Your provider can order metabolic testing if stones recur frequently.
What everyday prevention steps can you start now?
Increase daily water intake, reduce salt, eat moderate protein, and get recommended dietary calcium. Monitor your urine color, follow medical advice on supplements, and schedule follow-up testing after an episode to tailor prevention to your specific stone type.
