Shock kidney stones, also called extracorporeal shock wave lithotripsy, may be somewhat painful because it is a minimally invasive lithotripsy procedure in which the stones inside the kidney are broken into powder or fine particles by focusing the shock waves from the machine outside, and then discharged through the ureter. Because the stones are very hard, pain will be felt during the process of stone crushing, but most patients can tolerate it. Even if the stone is shattered, it may still scratch the mucosa of the ureter, so pain may occur during the process of stone removal, and usually this pain will slowly decrease in about two or three days after the operation. After the surgery, it is recommended to lie down for a period of time and then drink a lot of water, which can promote the discharge of stones to relieve the pain. In addition, it is recommended to apply pain medications for symptomatic treatment after surgery, such as diclofenac sodium and Keflex for pain relief, which can relieve the patient’s pain.
