A kidney stone is a common health issue that can affect anyone, though some individuals are more prone to developing it. These small, hard deposits in the kidneys, often addressed in the field of urology, can vary in size and severity. While many kidney stones pass naturally or are treated without complications, neglecting treatment for kidney stones can result in severe and even life-threatening consequences.
If left untreated, kidney stones can cause prolonged pain, urinary tract infections (UTIs), and in severe cases, permanent kidney damage or failure. The obstruction caused by a stone may lead to urine buildup in the kidneys, a condition known as hydronephrosis, which can impair kidney function over time. Untreated stones also heighten the risk of recurrent infections, sepsis, and other dangerous complications.
If you suspect you have a kidney stone, it’s crucial to seek medical attention promptly. Early intervention not only relieves discomfort but also prevents long-term damage and health risks.
Remember, timely treatment of kidney stones can save you from unnecessary complications and help preserve your overall kidney health.

What Are Kidney Stones?
Kidney stones are hard deposits of salts and minerals, primarily composed of calcium or uric acid, that form in the kidneys and can travel through the urinary tract. They vary widely in size, ranging from tiny, grain-like stones to larger ones that can occupy significant portions of the kidney.
How Kidney Stones Form
Kidney stones develop when certain minerals in your urine become too concentrated, often due to dehydration. When the mineral levels are high, they crystallize and form stones. Factors like insufficient hydration, diabetes, obesity, and genetic conditions like cystinuria increase the risk of kidney stones. Men are more likely to develop kidney stones, with 11% of men and 6% of women in the U.S. experiencing them at least once in their lifetime.
Identifying a kidney stone on your own can be challenging because its symptoms often resemble those of other medical conditions. A definitive diagnosis typically requires professional evaluation, including imaging studies and diagnostic tools that can confirm the presence, size, and location of a stone. However, recognizing the common signs of kidney stones can help you determine when it’s time to seek medical attention.
Here are some Common symptoms of kidney stones that may require a urologist visit include:
- Flank Pain: Sharp or severe pain on one side of your body, often near the lower back or side.
- Back Pain: Persistent or intense pain in the back.
- Pain Radiating to the Abdomen: Discomfort that starts in the back or flank and moves toward the stomach or groin.
- Burning Sensation During Urination: Pain or discomfort while urinating.
- Frequent Urination: An increased urge to urinate, sometimes in small amounts.
- Blood in the Urine (Hematuria): Pink, red, or brown discoloration in your urine.
- Fever or Chills: Often a sign of an infection, which may accompany kidney stones.
- Nausea or Vomiting: A common response to the severe pain caused by kidney stones.
If the stone is small enough, it may travel through the bladder and urethra, exiting through urine. Most stones pass naturally within 31 to 45 days, but larger stones may require intervention to prevent kidney damage.
Do All Kidney Stones Need Treatment?
Not all kidney stones require medical intervention. In fact, smaller stones—typically 4mm or less—often pass naturally through the urinary tract without the need for treatment. However, certain circumstances may necessitate professional care to prevent complications or alleviate severe symptoms.
Here are some scenarios where treatment is usually required:
- Stones Larger Than 6mm: These are unlikely to pass on their own and often require medical procedures for removal.
- Prolonged Presence: If a stone hasn’t passed naturally within 30–60 days, treatment may be necessary to avoid long-term complications.
- Severe Symptoms: Stones causing intense pain, recurrent infections, nausea, vomiting, or blood in the urine often require prompt treatment to relieve symptoms and protect kidney health.
If you suspect a kidney stone or are experiencing symptoms, consult a healthcare provider. Early evaluation can help determine whether you need treatment and what approach is most appropriate for your condition.

What Happens if Kidney Stone Untreated?
Ignoring a kidney stone can lead to serious health complications, particularly if the stone is large, causes a blockage, or triggers other symptoms. While smaller stones often pass naturally, leaving a kidney stone untreated may result in the following problems:
Potential Risks of Untreated Kidney Stones
- Severe Pain: Untreated kidney stones can cause persistent, excruciating pain in the back, side, or lower abdomen, interfering with daily activities and quality of life.
- Urinary Tract Infections (UTIs): A kidney stone can obstruct the urinary tract, making it easier for bacteria to grow and causing infections. Symptoms of a UTI include fever, chills, and painful urination.
- Hydronephrosis: A blockage caused by a stone can lead to a backup of urine in the kidney, causing swelling and damage—a condition called hydronephrosis. Prolonged cases can impair kidney function.
- Kidney Damage or Failure: Over time, untreated stones can lead to permanent kidney damage or, in severe cases, kidney failure, especially if infections or blockages persist.
- Sepsis: If an infection occurs and spreads, it can lead to sepsis, a life-threatening condition where the body’s response to infection causes widespread inflammation and organ failure.
Treatment and Prevention
The approach to treating kidney stones depends on their size, location, and severity of symptoms:
- Small Stones: These may pass naturally through the urinary tract. Drinking plenty of water, taking pain relievers, and using prescribed medications to relax the ureter can help facilitate this process.
- Large or Persistent Stones: For stones that are too large to pass or causing significant symptoms, medical procedures such as lithotripsy (shock wave treatment to break up stones), ureteroscopy (using a small scope to remove or break the stone), or surgery may be necessary.
Preventing Kidney Stones
Prevention is key to avoiding the pain and complications of kidney stones. Here are some effective strategies:
- Stay Hydrated: Drink plenty of water daily to dilute minerals in the urine.
- Maintain a Healthy Diet: Eat a balanced diet low in salt and processed foods.
- Watch Your Oxalate Intake: Limit high-oxalate foods like spinach, rhubarb, and beets, especially if you are prone to certain types of stones.
- Manage Weight: Losing excess weight can reduce your risk of kidney stones.
- Medications: If you are at high risk, your doctor may prescribe medications to prevent stone formation.
- Limit Certain Beverages: Reduce intake of sugary drinks, alcohol, and caffeine, which may increase dehydration or stone risk.
Additional Tips for Kidney Health
- Regular Exercise: Physical activity supports overall kidney health.
- Avoid Smoking: Smoking, including the use of cigarettes, can damage the kidneys and significantly increase the risk of developing kidney stones.
- Alcohol Moderation: Keep alcohol consumption within healthy limits.
- Medication Management: Discuss medications that may elevate your risk with your doctor to find safer alternatives or preventive measures.
Why Prevention Matters
If you’ve had a kidney stone before, you’re at higher risk of recurrence. Working with your doctor to implement preventive strategies can help reduce this risk and ensure your kidneys stay healthy.
Taking these steps can minimize the likelihood of kidney stones and protect your overall kidney health. If you’re concerned about your risk, consult your healthcare provider for personalized advice.

When to See a Doctor for Kidney Stones
If you suspect you have kidney stones, it’s important to contact your doctor for evaluation and guidance. Early intervention can prevent complications and alleviate discomfort. However, certain symptoms require immediate medical attention, as they could signal a serious infection or other complications.
Seek Immediate Medical Help If You Experience:
- Severe, Unrelenting Pain: Pain so intense that you cannot find relief or get comfortable.
- Nausea, Vomiting, Fever, or Chills: These symptoms, especially when combined with pain, may indicate an infection or other urgent issue.
- Blood in Your Urine: Visible pink, red, or brown discoloration in your urine could indicate the presence of blood in the urine, a condition known as hematuria.
- Difficulty Urinating: Trouble passing urine, which could mean a blockage is preventing normal urinary flow.
Why Prompt Medical Attention Matters
A kidney stone untreated can lead to serious complications, including kidney damage, infections, and urinary tract blockages. Consulting a healthcare provider at the first sign of concerning symptoms ensures you receive timely care and the most appropriate treatment plan.
Conclusion
Kidney stones, though common, can pose significant health risks if left untreated. From severe pain to life-threatening complications like kidney damage and infections, the consequences are serious. Consulting a urologist at the first signs of trouble can make a crucial difference in diagnosis and treatment. By recognizing symptoms early, seeking timely medical attention, and adopting preventive measures such as proper hydration and a balanced diet, you can manage kidney stones effectively. Whether through natural passing or medical treatment, addressing kidney stones promptly ensures better health outcomes and reduces the risk of recurrence. Don’t ignore the signs—your kidney health depends on it.
