Ureteral stones of about 6 mm do not require lithotripsy treatment. Patients only need to drink more water, take oral lithotripsy medication and exercise appropriately, which can be eliminated by themselves in most cases. If the stone causes acute pain that lasts for a long time and cannot be relieved, extracorporeal shock wave lithotripsy is recommended. After lithotripsy, the symptoms of renal colic can be reduced. Even after extracorporeal shock wave lithotripsy, it can be expelled from the body faster. Extracorporeal shock wave lithotripsy can be performed for patients who have severe renal colic and oral medication is not effective. If the pain is mild or can be relieved by oral pain medication or lithotripsy medication, it is recommended to continue to drink more water, urinate more, and exercise more so that the stones can be expelled more quickly. If the stone stays for a long time and causes severe hydronephrosis, extracorporeal shock wave lithotripsy can be performed at this time.
