Kidney Stone Symptoms: Dangerous Consequences

Last Updated on November 25, 2025 by

Not treating a kidney stone can cause serious health problems. Nephrolithiasis, or kidney stones, can cause kidney pain and flank pain. But the biggest worry is the complications that can happen if not treated.

Ignoring kidney stone symptoms can harm your health quietly. Up to 50“67% of people with untreated kidney stones might get chronic kidney disease (CKD). They face a 22“46% higher risk of losing kidney function over time. It’s important to get help quickly to avoid serious problems, like infections that can be deadly.

Key Takeaways

  • Untreated kidney stones can lead to chronic kidney disease (CKD).
  • There’s a significant risk of sustained kidney function decline.
  • Ignoring kidney stone symptoms can lead to serious infections.
  • Timely medical care is essential to prevent long-term damage.
  • Complications from untreated kidney stones can be life-threatening.

Understanding Kidney Stones: Location and Formation

It’s important to know about kidney stones to prevent and treat them. Kidney stones, or nephrolithiasis, are hard deposits made of minerals and salts. They form inside the kidneys. The kidneys are in the lower back, filtering waste from the blood.

What Are Kidney Stones and Where Do They Form?

Kidney stones form when minerals in the urine crystallize and clump together. This can happen due to dehydration, diet, and genetics.

Stones usually form in the kidneys but can also occur in other parts of the urinary tract.

Common Causes of Kidney Stone Development

Several factors can lead to kidney stones. These include:

  • Inadequate hydration: Not drinking enough water can increase the risk.
  • Dietary factors: Eating foods high in oxalate, sodium, and animal protein can raise the risk.
  • Genetic predisposition: Having a family history of kidney stones can increase your risk.
  • Medical conditions: Certain conditions, like hyperparathyroidism and urinary tract infections, can also contribute.

Types of Kidney Stones and Their Composition

There are several types of kidney stones, each with different compositions:

  • Calcium stones: The most common type, often made of calcium oxalate.
  • Uric acid stones: Formed in people who lose too much fluid, eat a high-protein diet, or have diabetes or obesity.
  • Struvite stones: Typically occur in people with urinary tract infections (UTIs).
  • Cystine stones: Rare and usually run in families, associated with a genetic disorder called cystinuria.

Knowing about the different types of kidney stones and their causes helps in prevention and treatment.

Recognizing Common Kidney Stone Symptoms

Knowing the signs of kidney stones can help with treatment. These stones can cause mild discomfort or severe pain.

Early Warning Signs and Flank Pain

Flank pain is an early sign of kidney stones. It feels like a dull ache or sharp pain on one side of the back or abdomen. It’s vital to notice these signs early to get medical help quickly.

Other early signs include changes in how often you urinate and blood in your urine. Some people might also feel nauseous or vomit.

Severe Kidney Stone Pain and Renal Colic

Kidney stones often cause severe pain, known as renal colic. This pain is intense and can move from the flank to the lower abdomen or groin. Renal colic pain is usually crampy and comes and goes.

This pain is so bad that people might pace or change positions to find relief.

When Symptoms Indicate a Medical Emergency

Sometimes, kidney stone symptoms mean you need emergency care. Severe pain, fever, chills, or trouble urinating are signs to seek help right away.

It’s important to know when symptoms are a medical emergency. For example, a blockage can cause infection or harm the kidney.

“Prompt medical intervention is critical to prevent long-term damage and complications.”-Experts highhlight.

If you think you have a kidney stone or have severe symptoms, get medical help without delay.

Risk 1: Chronic Kidney Disease Development

Untreated kidney stones can harm your kidneys a lot. They might even lead to chronic kidney disease. We look at the dangers of not treating kidney stones, focusing on CKD.

Statistical Risk of CKD

Research shows that many people with untreated kidney stones get CKD. About 50% to 67% of cases can lead to this disease. This shows why treating kidney stones quickly is key.

Accelerating Kidney Function Decline

Kidney stones can block urine flow, causing kidney pressure. This can cause inflammation and scarring. It makes the kidneys work less well over time.

Long-term Impact on Renal Health

Untreated kidney stones can badly harm your kidneys in the long run. CKD from untreated stones can lead to needing dialysis or a transplant. It’s vital to keep your kidneys healthy by treating stones properly.

We stress the need to treat kidney stones fast to avoid CKD. Knowing the risks and acting early can greatly lower your chance of getting CKD.

Risk 2: Serious Infection Complications

Untreated kidney stones can cause serious infections. This is a big risk for patients’ health. Kidney stones can block urine flow, creating a perfect spot for bacteria to grow.

Urinary Tract Infections from Stone Blockage

Urinary tract infections (UTIs) often happen with kidney stones. A stone blocking urine flow lets bacteria multiply, causing infection. UTIs can be severe and need immediate medical attention to avoid worse problems.

Struvite Stones and Their Connection to End-Stage Renal Disease

Struvite stones, linked to UTIs, can lead to serious issues like end-stage renal disease. These stones form from magnesium ammonium phosphate and are common in UTI patients. Having struvite stones means a higher risk of chronic kidney disease.

Life-Threatening Urosepsis: When Infections Become Systemic

In severe cases, untreated UTIs can turn into urosepsis, a life-threatening condition. This happens when the infection spreads to the blood. Urosepsis is a medical emergency that needs quick treatment. Early action is key to avoiding serious issues.

We know the danger of serious infection complications from untreated kidney stones is a big worry. It’s vital for patients to get medical help if they have UTI symptoms or other kidney stone issues.

Risk 3: Structural Damage and Kidney Function Loss

Untreated kidney stones can harm your kidneys. They might cause damage and reduce kidney function. A stone blocking the urinary tract can lead to many problems.

Hydronephrosis: Kidney Swelling from Obstruction

One problem is hydronephrosis, where the kidney swells. This happens when urine can’t flow because of a stone. The buildup of urine puts pressure on the kidney.

Prolonged obstruction can lead to significant kidney damage. The high pressure can harm the kidney’s delicate parts. This can cause permanent damage if not treated quickly.

Mechanisms of Permanent Tissue Damage

Damage from kidney stones involves complex processes. An obstructing stone increases pressure in the kidney. If this lasts too long, it can damage the kidney’s tissue permanently.

As stated by a leading medical expert, “The longer the obstruction, the higher the risk of permanent damage. This can lead to a decrease in kidney function.”

High Recurrence Rates: Why One Stone Often Leads to More

People who have had a kidney stone are more likely to get another. Studies show many will have another stone within a few years without prevention.

“The risk of recurrence is a critical concern, highlighting the need for effective management to prevent future stones and reduce complications.”

Conclusion: Prevention and Treatment Options

Preventing kidney stones and treating them early can greatly reduce discomfort and health problems. The American Urological Association suggests drinking more than 2.0“2.5 L of water a day. This helps lower the risk of getting calcium stones in the kidneys.

To avoid kidney stones, making smart food choices is key. Eating enough calcium (1000“1200 mg/d) and not too much sodium (2 or 3“5 g/d) helps. Also, eating more plant proteins and staying hydrated are important.

By choosing a healthier lifestyle and getting treatment when needed, you can avoid serious kidney stone problems. Treatment can include medicines or surgery. Natural products, like probiotics, may also help prevent kidney stones.
