When the stone is too large to pass easily, the pain continues as the muscles in the wall of the tiny ureter try to squeeze the stone along into the bladder. As a stone grows or moves, blood may be found in the urine. As the stone moves down the ureter closer to the bladder, a person may feel the need to urinate more often or feel a burning sensation during urination. These stones are likely to pass without being noticed. More often, kidney stones are found on an x-ray or sonogram taken on someone who complains of blood in the urine or sudden pain.
Diagnostic images give information about the stone's size and location.
Blood and urine tests also help detect any abnormal substance that might promote stone formation. In cases that cause lasting symptoms or other complications, kidney stones may be treated by various techniques, depending upon your physician's recommendation, your medical profile, and the severity of the condition. A special instrument goes through this tunnel allowing the doctor to locate and remove the stone. A cage is used to retrieve the stone and remove it from the body. Ginger ale, lemon-lime sodas, and fruit juices are acceptable, but water is best.
