Hello photonow. Welcome to the forum, mate.
I've had robotic surgery. As Andy says, "It's really early days yet."
To me, you seem to be making a great recovery, but be careful not to overdo things. Over exercising could impede progress rather than helping it.
I'm two years post op, and still usually have to get up for a pee at least once or twice a night. Like you, I'm 68 years old, so I'm not sure if this slight nocturia, is solely down to the op or whether it's more an age related problem. Likewise, I try and comfort myself, by using the same reasoning to my ED issues.
I found, early days, using a bed protector and a urine jug helped me. I felt more relaxed using them, which aided better sleep and seemed to reduce the need to pee at night. It also obviously helps if you drink less on an evening. I rarely drink anything after 7pm.
I was told by my CNS that the 'average' time it took to recover full continence was about six months.
Best of luck.👍
