Камни на УЗИ теперь не видны, теперь на УЗИ кроме кист вообще ничего не видят А раньше самый большой камень был 8 мм, вряд ли с ним нужно что-то делать.

Your kidneys are responsible for removing excess fluid from your body and filtering out unneeded electrolytes and wastes from your blood, resulting in the production of urine.

Kidney stones form when the minerals and acid salts in your urine crystallize, stick together, and solidify into a mass. This happens when your urine contains more crystal-forming substances, such as calcium and uric acid, than the available fluid can dilute. This can happen when urine is highly acid or highly alkaline.

The conditions allowing kidney stones to form are created by problems in the way your body absorbs and eliminates calcium and other substances. Sometimes the underlying cause is a metabolic disorder or kidney disease.

Certain drugs can also promote kidney stones, such as Lasix (furosemide), Topomax (topiramate), and Xenical, among others. Many times, it is a combination of factors that create an environment favorable to stone formation.

You won’t know you have a stone until it moves into the urethra—the tube connecting your kidney and your bladder. Common symptoms include[2]:

• 
  
  Pain in your side and back, below your ribs
  
  


• 
  
  Episodes of pain lasting 20 to 60 minutes, of varying intensity
  
  



• Pain “waves” radiating from your side and back, to your lower abdomen and groin
  
  


• 
  
  Bloody, cloudy or foul-smelling urine
  
  


• 
  
  Pain with urination



• 
  
  Nausea and vomiting
  
  


• 
  
  “Urgency” (persistent urge to urinate)
  
  



• Fever and chills (indicates an infection is also present)
  
  

The pain is a result of distention of the tissues above the stone, since it is blocking the passage of urine, rather than from the pressure of the stone itself.

Healthy Lifestyle is KEY to Avoiding Kidney Stones

Another risk factor is being sedentary. You’re more prone to kidney stones if you’re bedridden or very sedentary for a long period of time, partly because limited activity can cause your bones to release more calcium.

High blood pressure doubles your risk for kidney stones.

Digestive problems also increase your risk, since changes in the digestive process affect your absorption of calcium and other minerals.

A diet high in sugar can set you up for stones, since sugar upsets the mineral relationships in your body by interfering with calcium and magnesium absorption. Not only does sugar and high fructose corn syrup lead to obesity and diabetes, but also the current over-the-top consumption of these unhealthy sugars by children is a large factor in why children as young as age 5 or 6 are now turning up with kidney stones.

A 1999 South African study[3] found that drinking soda exacerbates conditions in the urine that lead to formation of calcium oxalate kidney stone problems.

Diets high in processed salt are also bad news. Salt increases the amount of calcium and oxalate in your urine. And processed foods are extremely high in salt.

Dr. Bruce L. Slaughenhoupt, co-director of pediatric urology at the University of Wisconsin, reports a huge increase in the salt load of children’s diets -- from salty chips, French fries, sandwich meats, canned soups, and sports drinks like Gatorade, which are now sold in child-friendly juice boxes. He believes the overconsumption of processed foods by children today is the cause of increased kidney stones in children2.

Not surprisingly, there also appears to be a connection between childhood obesity and kidney stones.[4]. Children are notorious for not drinking enough water, adding to the problem.

Consumption of soy can predispose you to developing kidney stones due to high levels of oxalate present in many varieties of soybeans. One more nail in the coffin for non-fermented soy!

And finally, caffeine has been linked to kidney stones. In one study, caffeine was given to people with a history of kidney stones, after which their urine was examined. The subjects showed elevated urine calcium, putting them at higher risk for kidney stones.
