Sorry you’ve had that experience! Not what you need after a major op as well as all the stress of diagnosis before. I can only quote our experience (husbands). He was catheterised for four weeks because of a difficult join of urethra to bladder. On the removal day, a scan was done with a liquid pressure/leak test to check the join before removal of catheter. They removed it and we had to hang around for a couple of hours to make sure he passed urine first.
