Kidney stones are usually treated without anesthesia. Kidney stone is usually said to be extracorporeal shock wave lithotripsy, this lithotripsy trauma is relatively small, the pain of the vast majority of patients can effectively tolerate. For patients who have poor tolerance, Diclofenac suppository 50mg can be given before lithotripsy, intra-anal administration, which can effectively relieve the pain and ensure that the lithotripsy process is completed successfully. For kidney stones before lithotripsy, the infection should be effectively controlled, and the red blood cells and white blood cells in the urine routine are significantly reduced, and the white blood cells in the blood routine are not more than 10,000 units, so that it is safe. For the active stage of stone or the infection is not effectively controlled, lithotripsy can easily lead to the occurrence of septicemia.
