Can Kidney Stones Cause Kidney Failure?

Understanding Kidney Stones

The kidneys filter waste and excess fluids from the blood, converting them into urine. Sometimes, substances such as calcium, oxalate, or uric acid can build up and form crystals, which grow into kidney stones.

Types of Kidney Stones:

• - Calcium Stones: Most common, usually made of calcium oxalate.
• - Uric Acid Stones: Linked to high-protein diets and gout.
• - Struvite Stones: Often caused by urinary tract infections (UTIs).
• - Cystine Stones: Rare, often due to genetic disorders.

The size of kidney stones can range from a grain of sand to several centimeters. The danger increases when stones obstruct the urinary tract or remain untreated for a long time.

Can Kidney Stones Cause Kidney Failure?

Short answer: yes—but it’s uncommon and usually happens when stones are not treated properly or lead to chronic obstruction or infection.

How Kidney Stones Can Lead to Kidney Failure

• 1. Blockage of Urine Flow: Large stones can obstruct the ureter, causing hydronephrosis (kidney swelling) and tissue damage. Prolonged obstruction may permanently reduce kidney function.
• 2. Recurrent Infections: Stones can harbor bacteria, causing repeated UTIs or pyelonephritis that scar kidney tissue and impair filtration.
• 3. Chronic Kidney Disease (CKD): Repeated obstruction or inflammation can gradually reduce kidney performance, potentially progressing to end-stage renal disease (ESRD).
• 4. Acute Kidney Injury (AKI): Sudden obstruction in both kidneys or a single functioning kidney can rapidly drop kidney function and requires emergency care.

Signs That Stones May Be Affecting Kidney Function

Recognizing symptoms early is crucial to prevent complications. Watch out for the following warning signs:

• - Severe, sharp pain in the lower back, side, or abdomen
• - Blood in urine (hematuria)
• - Cloudy or foul-smelling urine
• - Frequent urge to urination
• - Fever and chills (possible infection)
• - Nausea or vomiting
• - Reduced urine output or difficulty passing urine
• - Swelling in legs, ankles, or around the eyes (advanced kidney issues)

If you experience these symptoms, especially persistent pain or infection, consult a urologist immediately

How Kidney Stones Are Diagnosed

Early detection prevents complications. At Mitr Urology Associates, we use advanced imaging and lab tests:

• - Ultrasound: Quick, radiation-free detection of stones or swelling.
• - Non-contrast CT Scan: Most accurate for stone size, shape, and location.
• - Urine Analysis: Detects blood, infection, and mineral levels.
• - Blood Tests: Evaluates kidney function through creatinine and urea levels.
• - X-ray (KUB):Useful for certain types of stones.

Based on these findings, your doctor determines the right treatment approach.

How Kidney Stones Are Treated

Treatment depends on stone size, location, symptoms, and whether kidney function is compromised.

1) Conservative Management

Small stones (below 5mm) often pass naturally with:

• - Increase water intake
• - Pain relief medication as prescribed
• - Alpha-blockers to relax ureters and ease passage
• - Dietary changes to prevent recurrence

2) Minimally Invasive Procedures

For larger stones or those causing obstruction or infection:

• - ESWL: Uses sound waves to break stones into smaller fragments.
• - URS:A small scope is inserted via the urethra to locate and remove or fragment stones.
• - PCNL:A minimally invasive surgery to remove large or complex kidney stones directly.

3) Emergency Treatment

If stones cause infection or kidney blockage, immediate medical care is required. Temporary stent placement or nephrostomy may be performed to relieve pressure and restore urine flow.

Can Kidney Damage Be Reversed?

If detected early, kidney damage from stones can often be partially or fully reversed once obstruction or infection is treated. However, prolonged, untreated obstruction or repeated infections can lead to permanent kidney scarring. Early diagnosis, proper hydration, and timely intervention play a key role in preserving kidney health.

Prevention: Protecting Your Kidneys

Prevention is always better than cure. You can lower your risk of kidney stones — and protect your kidneys — through these lifestyle modifications:

• 1. Stay Hydrated:
  - Drink at least 2.5 to 3 liters of water daily.
  - Ensure urine remains pale yellow, indicating proper hydration.
• 2. Balanced Diet:
  - Limit foods high in oxalate (like spinach, nuts, and tea).
  - Reduce salt and animal protein intake.
  - Increase fruits and vegetables rich in citrate, which prevent stone formation.
• 3. Calcium Intake:
  - Do not avoid calcium completely; low calcium diets can actually increase oxalate absorption.
  - Instead, maintain a moderate calcium intake from natural sources.
• 4. Avoid Sugary Drinks:
  - Soft drinks and energy drinks with high fructose corn syrup can raise stone risk.
• 5. Regular Check-ups:
  - If you have a history of kidney stones or chronic diseases like diabetes or hypertension, schedule periodic kidney function tests.
• 6. Follow Medical Advice:
  - Take prescribed medications regularly, especially if you have recurring stones.
  - Consult a urologist before trying home remedies or supplements

Who Is at Higher Risk of Kidney Stones and Kidney Failure?

Certain individuals are more vulnerable to complications from stones, including:

• - People with recurrent urinary tract infections
• - Patients with diabetes, hypertension, or obesity
• - Individuals with a family history of kidney stones
• - Those consuming low fluid intake or high-sodium diets
• - People with one functioning kidney
• - Individuals taking certain medications (like diuretics or calcium supplements)

For such patients, proactive management and early treatment are essential to prevent kidney failure.

When to See a Urologist

Seek medical attention immediately if you experience:

• - Severe, persistent flank or abdominal pain
• - Fever or chills along with urinary symptoms
• - Decreased urine output or blood in urine
• - Recurrent episodes of stones

Ignoring symptoms can lead to infection, kidney damage, or in rare cases, kidney failure. At Mitr Urology Associates, our team provides expert diagnosis and advanced minimally invasive treatments to manage kidney stones effectively and protect long-term kidney health.
