Kidney Stones Archives - Health BeatHealth Beat

Kidney stones are solid masses or clusters of crystals that form from substances such as minerals, acids, and salts in the kidneys. These stones can be as small as a grain of sand, or in rare cases, larger than a golf ball.

Kidney stones occur when there is little liquid and too many of the minerals, acids, and other substances, such as calcium, sodium, oxalate, and uric acid, in the urine, causing them to stick together and form crystals or stones. Kidney stones can form over months or years.

There are four types of kidney stones, and they are named after the kind of crystal that they are made from. They include:

Calcium-oxalate and calcium phosphate stones are the most common types of kidney stones

Uric acid stones

Struvite stones

Cystine stones

Depending on the size of kidney stones, a person may not even realize that they have them. Smaller-sized stones can pass through the urinary tract in the urine without symptoms. However, larger-sized kidney stones can get trapped in the ureter, the tube that drains urine from the kidney down to the bladder, causing pee to back up and limit the kidney’s ability to filter waste from the body, which can also cause bleeding.

Kidney stones can take as long as three weeks to pass on their own. Sometimes, small stones can cause extreme pain as they go through the urinary tract and out of the body. If a kidney stone can’t pass on its own, a healthcare provider will need to break it up and remove it.

Kidney stones are common. About one in 10 people will get a kidney stone during their lifetime. They are most common in men who are in their 30s and 40s and among non-Hispanic white people.

The most common symptom of kidney stones is pain in the lower back, belly, or side, which might feel like it extends from the groin to the side. This pain can be dull, or it can be sharp and severe, and comes in waves. Other symptoms of kidney stones include:

Bloody urine

Pain when urinating

The inability to urinate

Feeling the urge to urinate a lot

Cloudy or foul-smelling urine

Nausea and vomiting

Fever or chills

Several risk factors can cause someone to develop kidney stones, including:

Not drinking enough fluids

Eating foods high in sodium or sugars

Eating meat and other protein-rich foods

Having a family history of kidney stones

Having a blockage in the urinary tract

Taking vitamin C supplements

Having had stomach or intestine surgery, including gastric bypass surgery

Taking certain medications, such as diuretics, calcium-based antacids, and some antiseizure medications

Having certain medical conditions, such as:

Cystic fibrosis

Diabetes

Gout

High blood pressure

High levels of calcium in the urine

Inflammatory bowel disease (IBD)

Kidney cysts

Obesity

Osteoporosis

Parathyroid disease

Primary hyperoxaluria

Hemiplegia or paraplegia, which are types of paralysis

Kidney stones can cause many complications, including:

Chronic kidney disease (CKD)

A blockage that backs up urine into the kidney, causing it to swell

Acute kidney injury

Kidney infection

Frequent urinary tract infections (UTIs)

A healthcare provider can diagnose kidney stones by performing urine, imaging, and blood tests.

To treat a small kidney stone, a healthcare provider will have the person monitor their symptoms until the stone passes in their urine. They may also prescribe medications to keep them comfortable and help the stone pass on its own. Larger kidney stones need treatment depending on their size, location, whether they are causing infections or symptoms, and other factors.

Medications to treat kidney stones help relax the ureter to help pass the stone more easily, help manage any nausea and vomiting, and help manage pain.

Procedures to remove large kidney stones include:

Shockwave lithotripsy

Ureteroscopy

Percutaneous nephrolithotomy

Laparoscopic surgery

It is important to note that the things we eat and drink impact our risk for kidney stones. Talk to your healthcare provider or a dietitian about ways to reduce your risk of developing kidney stones. They may recommend:

Drinking plenty of water

Limiting consumption of foods high in sugar and sodium

Limiting consumption of animal proteins

Maintaining a weight that is healthy for you

Eating foods that are good sources of calcium

Limiting consumption of foods high in oxalates

Prescription medications

You are out on a hot summer day participating in some type of physical activity and you feel a sudden sharp pain on your side or back. While the pain could be a number of things, there is a good chance that you have a kidney stone.

With summer’s heat and more increased physical activity, dehydration is a much more likely occurrence. With adequate hydration, calcium and other crystal forming substances cannot concentrate in the urine, but when someone is dehydrated, there is not enough fluid to dilute these substances, potentially causing kidney stones to form. Even though kidney stones are less than a centimeter in size, they can still cause intense discomfort.

Urologists at Jamaica Hospital Medical Center offer the following tips to reduce your chances of developing kidney stones this summer:

• Drink enough water – If you’re prone to kidney stones, your best defense is to stay hydrated during hot summer months. Hot temperatures make your body lose more water than usual, so it is important to replenish it throughout the day. You may need more than 64 ounces of water per day, depending on your weight and activity level.

• Eat less meat – A diet rich in animal protein can increase your risk for kidney stones, so try to minimize your consumption of burgers and other barbeque favorites and substitute them with other protein sources, such as beans, nuts and seeds.

• Limit your salt intake – Excess salt absorbs water in your system, which can also dehydrate you. Limit your daily sodium intake to 1500 mg or less per day by avoiding fast food, reading nutrition labels when you buy groceries, and cooking with less salt and more herbs and spices.

• Drink less caffeine – Even though you may think you are getting enough liquid by consuming caffeinated sodas, coffee, or tea, caffeine is a diuretic, meaning it can dehydrate you

Kidney stones sometimes do not cause symptoms. If the crystals are small enough, they may pass through urinary tract and out of the body without being felt. However, if a stone is large enough to attract attention, the first symptom is usually severe pain in the back and side that begins when the stone moves into the urinary tract, blocking the flow of urine. The pain may later spread to the groin and lower abdomen. Other symptoms include a persistent urge to urinate, painful urination, and pink, red, or brown urine

Seek medical attention if you have pain accompanied by nausea and vomiting or fever and chills, or if pain is so severe that you cannot sit still or find a comfortable position.

Jamaica Hospital’s Department of Urology offers a wide variety of treatment options for those suffering with kidney stones as well as many other conditions. For more information, or to schedule an appointment, please call 718-206-7110.
