Definition: What Is A Kidney Stone
Before we explore what kidney stones are, it is important to understand the basic anatomy and function of the urinary system. The urinary system is made up of the kidneys, the ureters, bladder, and urethra.
The kidneys act as filters for the blood, removing any waste products. These waste products are passed out of the body through our urine. The urine passes from the kidneys, through the ureters to the bladder. The bladder is where urine is stored until you are ready to urinate.
Kidney stones form from the crystallization of different substances within the kidney. This happens for a variety of reasons. These stones formed within the kidney are then typically released into the ureter . Symptoms can occur if these stones are large enough to obstruct the kidney or ureter.
There are four different types of kidney stones. They are named based on the substance from which they are formed.
Are Home Remedies Effective For Kidney Stones
For some people who have had many kidney stones, home care may be appropriate. When passing a kidney stone, drinking lots of fluid is important. In fact, this is the most important home care measure. Medications may help control the pain . However, if it is the first time one has had symptoms suggestive of a kidney stone, it is important to see a doctor right away.
Kidney Stone Signs And Symptoms
Kidney stones are conglomerations of crystals that form when concentrations of minerals in the urine become very high. As their name implies, stones almost always start in the kidneys. They may cause problems there, or may not be noticed until they move into the ureter . Once stones enter into the ureter the can obstruct the drainage of urine which generally causes symptoms such as pain in the upper back or lower abdomen, nausea, vomiting, and blood in the urine. Many stones will pass down the ureter, into the bladder and then be voided with urine. Occasionally stones can remain lodged in the ureter or within the bladder.

How Long Can You Wait To Pass A Upj Stone
If a patient does not pass the stone spontaneously in 30 days, then surgical treatment with ESWL or ureteroscopy is mandatory because long-term obstruction can damage the kidney. Typically, urologists may allow a patient to wait up to a month to pass the stone from the onset of symptoms as long as there are no signs of infection, pain is well controlled and kidney function is preserved.
If patient does not pass the stone within a month, then patient will be scheduled for a procedure to break the stone within 1-2 weeks .
If a patient develops severe pain or signs of infection, then urgent surgical intervention is mandatory. This is true for any obstructing stone in the ureter, at UPJ or at the UVJ.
If pain is significant and no infection is present, it is possible to insert a stent and do ureteroscopy with laser in one sitting.
If the ureter is too narrow, a stent is left in place for 1-2 weeks. The urologist then brings the patient back to the operating room once the stent has successfully dilated the ureter passively. This allows the urologist to go up the ureter with the ureteroscope and use laser to break up the stone.
ESWL is the preferred intervention if the stone is at the UPJ and is radio-opaque . The success rate of ESWL for UPJ stones is slightly lower than with ureteroscopy with laser. Sometimes more than one ESWL procedure is necessary.
For patients with multiple stones, laser lithotripsy may allow treatment of multiple stones in one sitting.

Kidney Stone Treatments: Your Options
Many people suffer from kidney stones, but they may not know what kidney stone treatments they have available to them. Benjamin Lee, MD is the Chief of Urology with the University of Arizona School of Medicine and a urologist in Tucson. He noted several treatments and a few facts about kidney stones you may find surprising.
To put the issue into perspective, lets look at some numbers:
- In 2000, 2 million people saw a doctor for kidney stones, totaling $2.1 billion in medical costs.
- 13 percent of men and 7 percent of women will have kidney stone.
- 1 in 11 people in the United States will develop a kidney stone.
- Once someone has developed a stone, there is a 50 percent chance they will get another one in 5 years.

Not every stone needs to be treated, though. Some are small enough to pass on their own when you urinate. Dr. Lee noted a 3 mm stone has about 80 percent chance of passing on its own. At about 5 mm, the odds are about 50 percent, but if a stone reaches 8 mm, the odds drop to 20 percent.

What Are Risk Factors You Can Control
Diet is a factor in some cases of kidney stones. A dietician can recommend foods to reduce the risk of kidney stones. Higher than recommended amounts of vitamin D, vitamin C, salt, protein, and foods containing high oxalates may increase the risk of stone formation.

Preventing Future Kidney Stones
If you had a calcium stone, your doctor may suggest cutting back on salt, which cause the body to dispense more calcium into the urine, as well as animal protein.

The best way to ward off new kidney stones is to drink enough water to keep urine clear.

What You Need To Know About Kidney Stones
Aug 07, 2019Cedars-Sinai Staff
Passing a kidney stone is said to be some of the most severe physical pain a person can experience.
You may picture someone passing a kidney stone in excruciating pain while a small rock moves through their bladder, but according to Dr. Brian Benway, director of the Comprehensive Kidney Stone Program, pain peaks much earlier in the stone’s journey.
Nothing subtle about a kidney stone
“Contrary to popular belief, passing a kidney stone once it reaches the bladder isn’t the painful part,” says Dr. Benway.
The pain usually starts once the stone has migrated from the kidney into the ureter, the tube that carries urine from the kidney to the bladder.
“Basically, for the first-timer with a kidney stone, the symptoms are not subtle.”
“The pain is usually sudden and quite severe on one side of your back and it can cause immediate nausea and vomiting,” says Dr. Benway
“Basically, for the first-timer with a kidney stone, the symptoms are not subtle.”
This sudden pain will begin to ebb and flow after the first few hours, gradually getting better after a few days. Dr. Benway says you shouldn’t wait for the pain to easeseek evaluation right away.
“Along with pain, kidney stones can sometimes be associated with infection, which will present itself as a fever,” he says.
“Go to the ER right away if you have strong pain with nausea or fever.”

How Does The Urinary System Work
The body takes nutrients from food and converts them to energy. After the body has taken the food that it needs, waste products are left behind in the bowel and in the blood.
The urinary system keeps chemicals, such as potassium and sodium, and water in balance, and removes a type of waste, called urea, from the blood. Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys.
Treatment: Shock Wave Therapy
The most common medical procedure for treating kidney stones is known as extracorporeal shock wave lithotripsy . This therapy uses high-energy shock waves to break a kidney stone into little pieces. The small pieces can then move through the urinary tract more easily. Side effects can include bleeding, bruising, or pain after the procedure.

When Surgery Is Necessary
If you think you might have a kidney stone, you should see your doctor as soon as possible. If youre found to have one, your doctor can help you determine whether to try to pass the stone naturally, take medication, or get the stone surgically removed.
In some circumstances, your doctor might recommend immediate surgical removal without a waiting period. This will usually be because the stone is too big to pass naturally or is blocking urine flow. If the stone is blocking the flow of urine, it can lead to an infection or renal damage.
In other circumstances, your doctor might recommend waiting to see if you can pass the stone on your own. You should check in with your doctor often during this time to see if anything is changing, especially if you have new symptoms.
During the waiting period, your doctor might recommend surgery if the stone continues to grow, youre having unmanageable pain, or you develop signs of infection, such as a fever. Infection, fever, kidney damage, intractable pain, or intractable vomiting are all indications for immediate surgery.
