Both childbirth and kidney stones are painful, but childbirth is more painful than kidney stones because the pain of childbirth is equivalent to 12 broken ribs at the same time. The pain of kidney stone is a kind of dull pain, when the stone of kidney stone falls into the ureter, it can cause colic, unbearable pain, rolling all over the floor, and it is difficult to stop the pain without applying drugs, such as progesterone, pethidine hydrochloride, morphine and so on. The pain of childbirth is usually gradually aggravated, while the pain of kidney stones is intermittent, and it is difficult to relieve the pain without eliminating the stones. Patients who have kidney stones are recommended to have effective treatment, such as extracorporeal shock wave lithotripsy or surgical stone extraction, in time when the pain of kidney stones is relieved.
