Hello,
I had a TURBT for a stage TA low grade papillary tumour 3.5 years ago at 37 years old. I have a huge phobia of GA. The anestesiologist had no issue with a spinal and neither did the surgeon. I felt a little pressure and discomfort while they were doing the procedure but it wasn’t bad at all. It took a few hours for me to get full feeling back in my legs but I was released the same day from the hospital. Due to the location of the tumour I had to have a stent place in my ureter so I had to keep my catheter in for 7 days after the surgery. Based on my experience I have no regrets going with the spinal. Best of luck.
