After having sudden severe pain in my side Friday night I was diagnosed with a kidney stone in the ER. CT scan shows one 5 mm stone. ER doc told me if I suddenly stopped having pain it meant the stone had gone into the bladder and the stone would pass. I left the ER after a demerol shot with very little discomfort up until last night when I did suddenly stop having all discomfort. I have been drinking 100 oz. of fluid a day, continuing last night and this morning, but still have passed nothing. I have been straining my urine as well. My question is: How long does it take to pass a kidney stone after it has made its way to the bladder?
