Kidney stones are hard deposits made of mineral and salt that form
inside your kidneys. Kidney stones have many causes and can affect
any part of your urinary tract-from your kidneys to your bladder.
Often stones form when the urine becomes concentrated allowing
minerals to crystallize and stick together. Passing kidney stones
can be quiet painful but the stones usually cause no permanent
damage if they're recognized in a timely fashion. Depending on your
situation you may need nothing more that to take pain medication
and drink lots of water to pass a kidney stone. In other instance
for example if a stone becomes lodged in the urinary tract are
associated with a urinary infection or cause complication surgery
may be needed. Your doctor may recommend preventing treatment to
reduce your risk of recurrent kidney stones if you're at increased
risk of developing them again.
