I had my hardware removed from L4-S1 on Monday. The surgery went as planned and only lasted about an hour. We had a few complications after surgery such as nauseau, low blood pressure (60/30), and trouble urinating. I left the hospital Thursday still unable to urinate with a catheter. I have an apt. Tuesday with the urologist and I hope at this apt. The catheter can be removed and I can urinate. My main question and concern is if anyone else had this issue after surgery? Any help or advice would be great.
