Suffering from kidney stones, kidney stones in the process of discharging downward, may be discharged to the end of the ureter, the diameter of the stone is small, discharged more smoothly, may soon be discharged, in order to promote the rapid discharging of the stone downward, you should drink more water, more urination, and repeatedly on the ureter to flush. Kidney stone diameter is large, due to the narrow end of the ureter, in the process of discharging may be stuck in the end of the ureter, can not be discharged, and there will be severe pain in the lower back and abdomen, urinary frequency, urinary urgency and other symptoms. If the stone is large and cannot be discharged by itself, extracorporeal shock wave lithotripsy or ureteroscopic lithotripsy should be carried out if necessary to avoid serious complications. If you feel unwell, you should go to the hospital in time and consult your physician for guidance.
