Kidney stones happen there not enough water in the urinary system to dissolve all the chemicals that the kidneys are trying to eliminate. That's why we tell all patients with kidney stones to drink enough water to make 2 liters (a little over ½ gallon) of urine per day.
Most patients who have kidney stones also have abnormal or less than optimal urinary chemistry. To determine what these problems are, we collect the patient's urine for 24 hours. An urologist who is an expert in stone disease reviews the test results and designs a treatment plan. In cases in which the stones are relatively small, usually 4 mm in size or less, special medications are given to help correct any abnormalities and enable the stone to pass. It is very important that patients follow the doctor's instructions, otherwise kidney stones may return.
If a kidney stone is too large to pass on its own, there are minimally invasive treatment options that can be used to eliminate it..
