Hi Mike,
I had robotic surgery almost exactly 6 months ago so know exactly how you feel. I have always walked a lot and, at first, wasn't able to do things at once - walk and control my bladder. I have kept doing the standard sets of kegels 6 times/day and bladder training as advised by the support team and my Hospital. The Hospital discharged me with a supply of active Fit Tena Men ( like a shield) and I went through about 4 or 5 a day. When the Continence service took over, I got deliveries of Comfort Mini (they hold up to 1 pint of liquid, I was told and are cheaper).
I now only use one of these a day, mainly as a safety net and am running and walking pretty closely to where I was pre operation. I was told by Continence Service that the target was 100% managed and guess I'm about there now.
Keep doing the exercises, you'll get there.
