Kidney stones will only go away if the stones are not in the obstructed area or if they are expelled from the body. If the stone is not expelled, it can cause constant or intermittent pain. When a kidney stone causes an obstruction in the urinary tract, such as an obstruction in the pelvic ureteral junction or an obstruction into the ureter, the pain may be constant until the stone passes through the ureter into the bladder, when the pain is relieved or disappears. It is also possible that with a change in position, the stone leaves the pelvic-ureteral junction and reaches the renal calyces, which may also reduce or eliminate the pain. However, if the stone is obstructed again, the pain may reappear. Therefore, the pain will not occur until the stone is completely removed from the kidney, but may occur intermittently or continuously as long as it is in the kidney. Therefore, if you have kidney stones, you need to go to the hospital for extracorporeal shock wave lithotripsy or surgery to remove the stones from your body, so that you can prevent the pain from reappearing.
