Water may help prevent kidney stones

- Christophe­r Chon, M.D.

Q:Whatare kidney stones and what causes them?

A:“Kidneyston­es are small, hard deposits that form inside your kidneys. The stones are made of mineral and acid salts. They have many causes and can affect any part of your urinary tract — from your kidneys to your bladder. Stones may form when urine becomes concentrat­ed, allowing minerals to crystalliz­e and stick together,” says Christophe­r Chon, M.D., chief of Urology at Kelsey-Seybold Clinic.

“A kidney stone might not cause symptoms until it moves around within your kidney or passes into your ureter — the tube connecting the kidney and bladder,” he says.

If that happens, signs and symptoms may include: • Severe pain in the side and back,

below the ribs. • Pain that spreads to the lower

abdomen and groin. • Pain that comes in waves and

fluctuates in intensity. • Pink, red or brown urine. • Nausea and vomiting. • Persistent urge to urinate.

“If someone in your family has kidney stones, you’re more likely to develop stones, too. If you’ve already had one or more kidney stones, you’re at increased risk of developing another. Other factors that may increase your risk of developing kidney stones include obesity not drinking enough water each day, eating foods high in protein, sodium and sugar, and certain medication­s,” Dr. Chon says.

If you have signs and symptoms of kidney stones, make an appointmen­t with your doctor.

“Treatment varies, depending on the type of stone. Most kidney stones won’t require invasive treatment. Those that can’t be treated with conservati­ve measures — either because they’re too large to pass on their own or because they cause bleeding, kidney damage or ongoing urinary tract infections — may require more invasive treatment including surgery,” says Dr. Chon, who cares for patients at Kelsey-Seybold’s Main Campus and Spring Medical and Diagnostic Center.
