Kidney Stones Definition A kidney stone is the result of a chemical reaction that occurs when the urine becomes concentrated and when certain substances combine together to create an object that is too large to pass in the urine. Calcium oxalate, calcium and ammonium phosphate, uric acid, cystine and other substances (such as calcium carbonate, magnesium, lysine, arginine and ornithine) in the urine crystallize to form a hard mineral deposit called a kidney stone. Description A kidney stone develops when substances in urine form crystals that stick together and grow in size. In most cases, these crystals are removed from the body by the flow of urine, but they sometimes stick to the lining of the kidney or settle in places where the urine flow fails to carry them away. These crystals may gather and grow into a stone, ranging in size from a grain of sand to a golf ball. Most stones start in the kidney. Some may travel to other parts of the urinary system, such as the ureter (the tube leading from the kidney to the bladder) or bladder, and grow there. The most common types of kidney stones are calcium stones, uric acid stones, struvite stones and cystine stones. Calcium stones are formed by a build-up of calcium, combining with oxalate, phosphate or carbonate. Calcium stones account for 75 to 85 percent of all stones and are more likely to occur in men.

Symptoms Diagnosis Expected Duration ... Additional Info What Is It? Kidney stones are abnormal, hard, chemical deposits that form inside the kidneys. This condition also is called nephrolithiasis or urolithiasis. Kidney stones are often as small as grains of sand and pass out of the body in urine without causing discomfort. The deposits can be pea sized, marble sized or even larger. Although some of these larger stones are too big to be flushed from the kidney, others manage to travel into the narrow tube between the kidney and bladder (ureter), where they become trapped. Trapped kidney stones can cause many different symptoms, including extreme pain, blocked urine flow and bleeding from the walls of the urinary tract.

HOME Popular Geology FSU USA ... IU MINERALOGY OF KIDNEY STONES Kidney stones are pathological crystalline build-ups in the human body that are usually minerals identical with those found in nature. A few of the crystalline compounds that may form are organic chemicals, like cystine (an amino acid) and uric acid. Most gall stones are also crystallized organic material, usually cholesterol. The exact cause of all kidney stones is not well understood, but factors probably include genetics, diet, and disease.

Chemically it is a complex calcium phosphate with attached molecules of hydroxyl (OH), fluorine (F), and sometimes, other elements. Apatite is the fundamental mineral component in bones and teeth, and when apatite has fluorine in its crystal structure, it is stronger. This is why fluorine is added to water and toothpaste. In kidney stones, carbonate (CO ) substitutes for some of the phosphate, making a mineral that is relatively poorly crystallized. Its formula in kidney stones is usually given as Ca

These substances in the urine may complex to form small crystals and subsequently stones. Stones may not produce symptoms until they begin to move down the ureter, causing pain. The pain is severe and often starts in the flank region and moves down to the groin. Kidney stones are common. About 5% of women and 10% of men will have at least one episode by age 70. Kidney stones affect about 2 out of every 1,000 people. Recurrence is common, and the risk of recurrence is greater if two or more episodes of kidney stones occur. Kidney stones are common in premature infants.

A stone may stay in the kidney or break loose and travel down the urinary tract. A small stone may pass all of the way out of the body without causing much pain. A larger stone may get stuck in a ureter (the tube that connects your kidneys and bladder), the bladder, or the urethra (the tube in your body that urine leaves from). A large stone can block the flow of urine and cause great pain. If you have a kidney stone, you may already know how painful it can be. Most kidney stones pass out of the body without help from a doctor, but sometimes a stone will not just go away or may even get larger. Your doctor can help.

An estimated 10% of people in the United States will have a kidney stone at some point in their lives. Men tend to be affected more frequently than women. Most kidney stones pass out of the body without any help from a doctor. Stones that cause lasting symptoms or other complications may be treated by various techniques, most of which do not involve major surgery. The kidneys are two bean-shaped organs located below the ribs toward the middle of the back. The kidneys remove extra water and wastes from the blood, converting it to urine. Narrow tubes called ureters carry urine from the kidneys to the bladder, where the urine is stored. Kidney Stone Formation A kidney stone is a hard mass that develops from crystals that form in the urine and build up in the kidney. Normally, urine contains chemicals that prevent the crystals from forming but these inhibitors do not seem to work for everyone. If the crystals remain tiny enough, they will travel through the urinary tract and pass out of the body in the urine without being noticed.

Kidney stones vary greatly in size. Some are as small as a grain of sand whereas others are so big they fill the entire renal pelvis. They are not always painful and are sometimes discovered completely by accident after an X-ray or ultrasound examination made for some other reason. Kidney stones typically occur in formerly healthy men aged between 30 and 50. The male to female ratio for kidney stone disease is 2:1. The cause of most stones is unknown but they can be associated with a high concentration of calcium in the urine or occasionally in the blood. They can also be caused by dehydration, infection, obstruction of urine and various kidney disorders.

Kidney Stones The cause of most kidney stones is not known. A stone may cause no problems, but often it causes pain. Most kidney stones are small, and pass out with the urine. About half of people who have a kidney stone develop another one at a later time in their life. Drinking lots of water may prevent a recurrence. How common are kidney stones? About 3 in 20 men, and 1 in 20 women in the UK develop a kidney stone at some stage in their life. It can occur at any age, but most commonly in middle age. About half of people who develop a kidney stone will have at least one recurrence at some stage in the future. How do kidney stones form? The kidneys filter the blood, and remove excess water and waste chemicals to produce urine. Urine travels from each kidney down a tube called the ureter into the bladder, then out of the body when the bladder is full. Many waste chemicals are 'dissolved' in the urine. Sometimes the waste chemicals form tiny crystals in the urine which may clump together to form a small stone. What causes kidney stones?

Comment on this article Kidney stones An introduction to kidney stones Kidney stones are among the most painful disorders to afflict humans. Fortunately, modern techniques for pain management and stone treatment and prevention are very effective. Most kidney stones pass out of the body without any intervention by a physician. Cases that cause lasting symptoms or other complications may be treated by various techniques, including extra-corporeal shock wve lithotripsy, laser destruction of the stone with ureteroscopy and percutaneous destruction of large kidney stones. Research advances also have led to a better understanding of the many factors that promote stone formation. In many cases changes in the diet can decisively prevent recurrences. Basic anatomy of the urinary tract The urinary tract, or system, consists of the kidneys, ureters, bladder, and urethra. The kidneys are two bean-shaped organs located below the ribs toward the middle of the back. The kidneys remove extra water and wastes from the blood, converting it to urine. They also keep a stable balance of salts and other substances in the blood. The kidneys produce hormones that help build strong bones and help form red blood cells.

Kidney Stones: Treatment with Lithotripsy Department of Urology University of Iowa Hospitals and Clinics First Published: January 2004 Last Revised: January 2004 Peer Review Status: Internally Peer Reviewed Lithotripsy is a treatment for kidney stones which has been in wide use since 1982. Lithotripsy works without open surgery. Kidney stones can be broken up with shock waves, and then the stone fragments pass out of the body in the urine. Lithotripsy is generally performed on an outpatient basis, often using sedation, but most frequently under a general anesthetic. The process uses a device called a lithotriptor. Because all the energy is generated by a machine outside the body and no incisions are made, the process is called Extracorporeal Shock Wave Lithotripsy (ESWL). This treatment can be used to break stones located in the kidney or in the ureter. Stones that are larger than 2 centimeters may be too large to fully break up with one treatment, and might be better treated by some other method, including open surgery. ESWL can be used in adults and in children, but care must be used to avoid injuring adjacent organs, such as the lungs, in children. Lithotriptors generate shock waves by various mechanisms but all fragment stones based on the same principles. Shock waves travel easily through the soft tissues of the body with minimal damage to surrounding structures, but are focused on the kidney stones. The stones absorb the energy from these waves and break up. Small stone fragments are then passed in the urine. The treatment is rarely painful, but passing the stone fragments may be.

Kidney Stones: What They Are Department of Urology University of Iowa Hospitals and Clinics First Published: January 2004 Last Revised: January 2004 Peer Review Status: Internally Peer Reviewed Kidney stones are a major health problem, affecting 2-3% of all Americans. Men are affected three times as often as women, and most frequent stone formers have their first stone in their 20s. Kidney stones are more common during hot weather, but can occur at any time of the year. A kidney stone is a collection of mineral salts and protein that collect to form a solid crystalline mass. They can start as tiny stones that pass in the urine unnoticed, or they may grow to a size that cannot be passed and become symptomatic. Most kidney stones are composed of calcium-containing crystals, but some are due to metabolic disturbances or chronic urinary tract infections. If a stone grows large enough it can get caught in the kidney or the ureter (the tube that drains the kidney into the bladder). Once it gets caught, the stone may partially or completely block the flow of urine. This blockage causes pain that is usually felt in the middle of the back or side and may radiate toward the groin. Sometimes the pain can be so severe as to cause nausea and vomiting. Fevers and chills may accompany a stone that is associated with infection. If a stone that is blocking urine flow is left untreated it can cause damage to the kidney or ureter. If your symptoms sound like you may have a stone your doctor may perform a full history and physical examination, check laboratory tests on your blood and urine, and order x-rays. The x-ray tests often include a plain film and/or CT scan of your abdomen. Other tests that may be considered include intravenous pyelography (IVP) or an ultrasound of your kidneys to detect blockage.
