I am in the uk and had a robotic prostate removal 5 weeks ago. I had a catheter for the first 10 days post op. Initially the challenge was to check the levels of the bag, as you have no physical sensation of how full it is. I removed mine at home as my hospital gave me notes and guidance on how to do it. It was quite ok and painfree. Occasionally I had a bit of blood while having the catheter, mainly caused by tension on the tube between the catheter and the penis. Nothing serious. For nighttime check you have enough movement.
Post catheter it’s a new learning curve to know when to pee, there is a disconnect between bladder and brain , this improves with time but not in a linear fashion.
As nerves renew you may get confusing signals as to what is a pee alert and what is just a nerve tingle. When it comes to pads, get a selection . I use a small pad at night, it is normally dry now .
The main problem area is during the day. The transition from sitting to standing or from lying down to sitting or standing. The bladder can get confused by sudden movement. Before you change position , think first and gradually change position.

Everyone is different, I hope this helps a bit. Wishing you all the best for your op.
