What Are Kidney Stones?

Kidney stones, also known as renal calculi, are solid masses formed when minerals and salts crystallize in your urine. These stones develop in the urinary tract, often in the kidneys, and can travel down into the bladder. The discomfort comes when the stones pass through the narrow ureters.

Types of Kidney Stones

There are several types of kidney stones, each formed from different substances:

  • Calcium oxalate stones: The most common form, usually created when calcium binds with oxalate, a substance found in some foods.
  • Uric acid stones: Often found in people who consume a lot of animal protein or have high uric acid levels in the blood.
  • Struvite stones: Typically develop due to frequent urinary tract infections.
  • Cystine stones: Caused by a rare genetic disorder called cystinuria.

Kidney Stone Symptoms and Risk Factors

Stone formation can be influenced by dehydration, dietary choices (especially high salt and calcium supplements), obesity, medical conditions, and even family history.

When kidney stones form, symptoms may include severe pain in your side and back or below the ribs. The pain may spread to the lower part of your stomach and groin. Kidney stones can also cause nausea, vomiting, blood in the urine, and difficulty urinating.

Other kidney stone symptoms can include cloudy or foul-smelling urine, fever, and chills. Recognizing these symptoms of kidney stones early can help manage complications before they escalate.

The Average Time to Pass a Kidney Stone

So, how long does it take to pass a kidney stone? That depends on the stone’s size, location, and type:

  • Small stones (less than 4mm): 80% of stones this size will pass naturally in about 31 days with adequate hydration and supportive care.
  • Medium stones (4mm to 6mm): These may take up to 45 days or longer to pass and often require medical management.
  • Large kidney stones (greater than 6mm): These are unlikely to pass on their own and usually need surgical or non-invasive procedures.

Hydration is key. Drinking enough fluids helps increase urine flow, which encourages kidney stones to pass more quickly. Physical activity and pain medication may also support the process of passing a kidney stone by relaxing the urinary tract and reducing discomfort.

Medical Procedures Used to Treat Kidney Stones

Sometimes, kidney stones are simply too large or too painful to pass on their own. In these cases, several medical procedures may be used:

  • Extracorporeal Shock Wave Lithotripsy (ESWL): This non-invasive treatment uses sound waves to break the stone into smaller fragments that can be passed naturally.
  • Ureteroscopy: A scope is inserted through the urethra and bladder to break or remove the stone.
  • Percutaneous Nephrolithotomy: A minimally invasive surgery used for large stones, especially when other methods fail.
  • Medications: Alpha-blockers may help relax the muscles in the ureter, allowing the stone to pass more easily.

At Urology of Greater Atlanta, our expert urologists provide customized treatment plans to reduce your pain and eliminate the risk of kidney stone recurrence.

When to Tell Your Doctor About Your Kidney Stones

You should call your doctor immediately if you experience:

  • Persistent or severe pain that doesn’t go away
  • Signs of infection, like fever or chills
  • Vomiting or inability to keep fluids down
  • Difficulty urinating or bloody urine

In some cases, blood tests and imaging (like CT scans) are used to determine the type of kidney stone and evaluate treatment options. Early detection and proper management are key to reducing the risk of kidney damage or recurrence.

Our board-certified team is experienced in diagnosing and treating all types of kidney stones, from calcium phosphate stones to rare cystine stones.

How To Prevent Future Kidney Stones

Preventing more kidney stones is possible with a few lifestyle changes:

  • Stay hydrated. Drink at least 2–3 liters of water daily.
  • Reduce animal protein intake.
  • Limit foods high in oxalate (spinach, nuts, tea).
  • Avoid excessive calcium supplements, unless recommended by a doctor.
  • Maintain a healthy weight and manage chronic conditions like kidney disease or gout.
  • Monitor salt intake to prevent stone formation.

People with a history of developing kidney stones may also benefit from regular checkups and personalized dietary plans to prevent kidney stones from forming again.
