I have been having kidney stone symptoms for about 6 weeks (blood, frequent urination, pelvic pain with no UTI present), but when they did a CT scan, there was no evidence of a stone. Two days later I had unbearable pain, nausea, etc., and went to the ER. The ultrasound showed complete blockage of the left ureter so they did another CT scan and found a 5mm stone stuck at the entrance to my bladder. There was no flow of urine (she watched via ultrasound for 30 minutes) on that side and my left kidney was swollen. So I was sent home and told to drink, move, etc. to try to get it to pass on its own. I am doing everything I can, and I don't think it has budged. I have incredible pressure and constant urgency to urinate, and by the end of the day each day I feel terrible. At what point is the complete urine blockage to the left kidney dangerous and how will I know before I get kidney damage. It has been nearly a week, and the doctor's office hasn't scheduled anything yet, but will if I hit 4 weeks. But meanwhile, they are not running tests or anything. It seems like this must be very hard on the kidney, so I am not sure if I should just keep drinking and exercising, doing cranberry, herms, taking Flomax, etc. or get a 2nd opinion. Also, if and when the stone makes it to the baldder, will it come out quickly or can that be a long process as well? Thanks for any advice. I am desperate!
