Patients who have kidney stones with renal colic are most likely to have renal colic caused by the displacement of the stone into the ureter. In this case, if the pain is unbearable and persistent, the patient should go to the hospital and undergo extracorporeal shock wave lithotripsy under ultrasound guidance. As long as the stone is smaller than the internal diameter of the ureter, it can be discharged by itself through conservative lithotripsy, and the local pain will be relieved significantly after lithotripsy. If the stones are small, less than 6 mm, and cannot be lithotripsy, oral medication to dilate the ureter can be given, such as mebendazole or intravenous scopolamine. In the case of stones at the end of the ureter, oral alpha-blockers can be administered, and all such pain symptoms will be significantly relieved. Patients can also use analgesic drugs during the acute phase of this pain, such as indomethacin suppositories and diclofenac suppositories, all of which can be administered rectally for analgesic effect after rectal absorption.
