If the kidney stone is in severe pain, it is recommended to go to the hospital immediately for treatment: 1. Intramuscular injections of brucizine hydrochloride, morphine hydrochloride injection, dulcolax injection and other drugs can be given to relieve the patient’s acute pain symptoms, and the pain can be relieved to varying degrees in about 5-10 minutes after the injection. 2. Intramuscular injections of scopolamine hydrochloride, which is not a pain-relieving drug, can be given. However, the injection may cause difficulty in urination or blurred vision. 3. Oral pain medication, such as oral diclofenac sodium capsule or oral fenbid capsule, tramadol tablets, etc., can be used for continuous maintenance analgesic treatment. 4. After the pain is relieved, treatment such as shock wave lithotripsy or surgery can be performed to remove the stones without recurrent pain.
