If the kidney stone causes stomach pain, then the treatment methods are as follows: 1. If you have the condition to go to the nearest hospital immediately for treatment, patients with severe pain can first intramuscular injection of pain medication, such as brucizine hydrochloride injection or dulcolax injection to relieve pain. After the pain is relieved, extracorporeal shock wave lithotripsy will be performed to treat the stone, and the pain will disappear after the stone is discharged. 2. If you do not have the conditions to go to the hospital immediately, you can temporarily take oral pain medication, such as oral diclofenac sodium capsules or oral tramadol tablets, ibuprofen extended-release capsules, etc. After taking oral medication, the pain can be relieved to a certain extent, and then go to the hospital for further treatment. 3. If oral pain medication or extracorporeal shock wave lithotripsy is not effective, hospitalization will be given and minimally invasive surgery will be chosen to remove the stones from the body. For patients with co-infection, surgery cannot be performed immediately, but medication is needed to control the infection and wait until the inflammation gradually subsides. Otherwise, the infection may spread and cause sepsis or infectious shock.
