Kidney Stones Q & A

What are kidney stones?

Kidney stones are made up of minerals and salts in your urine that can form hard, stone-like deposits in your kidneys. These deposits can be very small and may pass through your urinary system without you ever knowing they existed. Larger stones can become quite painful, however, when they move around in your kidney or begin to travel through the thin tubes, called ureters, which carry urine from your kidney to your bladder.

What are the symptoms of kidney stones?

A kidney stone that’s on the move may cause:

  • Severe pain in your side and back that typically occurs below the ribs
  • Pain that radiates to your lower abdomen and groin and may come in waves or fluctuate in intensity
  • Pink, red, or brown urine

What causes kidney stones?

Kidney stones may form when you have high levels of minerals, such as calcium, in your urine and not enough fluid to properly dilute these substances. Sometimes your urine lacks naturally-occurring substances that prevent minerals in your urine from clumping together.

To understand what’s causing your kidney stones, Dr. Coutinho may ask that you strain your urine so he can analyze the stones you pass. Calcium stones, for instance, are the most common type of kidney stones and are often due to high-calcium diets.

Struvite stones are a type of kidney stone that form in response to an infection, such as a urinary tract infection, and uric acid stones can occur in individuals who don’t drink enough fluid. Once he’s analyzed their chemical structure, Dr. Coutinho can develop a plan to help prevent more kidney stones from forming in the future.

What is the treatment for kidney stones?

Depending on the size and location of your stone, you may be able to pass it with pain medication and by drinking copious amounts of water. Many stones, however, are large enough that they require further treatment.

For larger stones or those causing significant pain, Dr. Coutinho may recommend:

  • Minimally-invasive laser surgery to break up and remove a stone that’s lodged in your ureter
  • Shockwave lithotripsy to break kidney stones into tiny pieces that can pass harmlessly through your urinary tract system
  • A surgical procedure called PCNL (percutaneous nephrolithotomy), during which Dr. Coutinho removes a kidney stone using small instruments inserted through small incisions in your back
