The pain caused by kidney stones, usually called renal colic, is very strong and may be very unbearable. Immediate pain relief methods are specifically as follows: 1. pain medication: pain relief may require diclofenac, taken orally or with suppositories, most of which can relieve pain in 5-10 minutes; 2. antispasmodic medication: such as 654-2 (eliminated scopolamine tablets) or atropine, which can relieve pain caused by ureteral spasm 3, other: when the pain is very severe, you may need to use more potent analgesic drugs such as dulcolax. After the above drugs are used, most of them can relieve the patient’s pain, but of course, the pain relief mostly needs to be treated in hospital. If the obstruction is heavy or causes pain caused by infection, it may be necessary to drain the ureter by placing a ureteral stent to relieve the patient’s pain.
