Stone Removal Day

After two CT scans, the doctor finally figured out that I have a 7 mm calcified stone by my bladder, which has been causing the pain in my lower back/side. There is less than a 10 percent chance that I would be able to pass the stone on my own, so I have to have it removed. I will go in on Friday morning and the procedure should take about an hour. I have to get put under, so I'm a little nervous. I've never had any type of surgery before. It's just an outpatient procedure, so I should be back home around noon. I will be glad when this is finally over and hopefully I won't have any more pain.
