Kidney Stones 101: Causes, Symptoms, and Treatment Options

What Are Kidney Stones?

Kidney stones are solid pieces of material that form when minerals and salts in your urine stick together and crystallize. These stones can be tiny like grains of sand or grow large enough to block the flow of urine, causing significant pain or complications.

Although they form in the kidneys, stones can travel and lodge anywhere along your urinary tract, which includes the ureters (the tubes between your kidneys and bladder), bladder, or urethra. Many people don’t realize they have a stone until it starts moving and causes symptoms.

While kidney stones can be alarming, they’re also common, and in many cases, treatable. The best first step if you suspect you have a stone is to stay hydrated and talk to a healthcare provider who can guide you on next steps. Granville Health System offers diagnosis and care for kidney stones throughout North Carolina and South Virginia.

Types of Kidney Stones

 

  • Calcium-Oxalate

    The most common type. Forms when there’s too much calcium or oxalate in urine—often linked to diet or absorption issues. Found in spinach, almonds, beets & chocolate.

  • Uric Acid

    Occurs when urine is overly acidic. Linked to high-protein diets, chronic diarrhea, diabetes or gout.

  • Struvite

    Forms after certain UTIs. Can grow rapidly into large “staghorn” stones requiring surgery.

  • Cystine

    A rare, genetic condition (cystinuria) causes excess cystine to crystallize.

  • Pediatric Stones

    Increasing in kids—likely linked to processed diets. Kids can form any of the adult stone types.

Symptoms

  • Severe back, side or groin pain
  • Blood in urine
  • Cloudy or foul-smelling urine
  • Fever & chills
  • Nausea & vomiting
  • Burning or difficulty urinating

Treatment Options

Small stones often pass with hydration and pain management. Larger stones may require:

  • Shock Wave Lithotripsy: Non-surgical, breaks stones with shock waves.
  • Ureteroscopy: Scope into bladder/ureter to remove or laser-break stones.
  • PCNL: Minimally invasive kidney entry for large/complex stones.
  • Surgery: Laparoscopic or open surgery for very large stones.

Frequently Asked Questions

Are kidney stones painful?

Yes. Kidney stone pain can be intense, starting in your side or back and moving lower as the stone travels. Some describe it as the worst pain of their life. Seek medical help for severe pain.

When should I see a doctor for kidney stones?

Go to a doctor if you have severe pain, fever, chills, difficulty urinating, or blood in your urine. These may be signs of a blockage or infection.

How can I prevent kidney stones?

Drink at least 8 cups of water daily. Reduce salt, limit animal protein, and avoid high-oxalate foods like spinach, nuts, and chocolate if advised. Talk to your doctor about your risk factors.

Can I pass a kidney stone at home?

Small stones can pass naturally with fluids and pain relief. Larger stones may need medical procedures. See a doctor if symptoms worsen.

What should I drink if I’m prone to stones?

Water is best. Lemon water helps prevent certain stones. Avoid excessive sodas and sugary drinks. Ask your doctor what’s best for your stone type.

Can kidney stones cause permanent damage?

Usually, stones don’t cause lasting harm if treated quickly. Frequent stones can damage your kidneys over time. Work with your doctor to prevent future stones.
