As regards having the catheter removed I posted to HH the other day my surgeon is convinced the swift pull on my sticking catheter was the start of my stricture problems.
You could be lucky and be dry from day one. At first you will want to go as soon as the urge comes on, as things progress try to hang on a bit longer before going to the loo. You are probably going to need too retrain the bladder, try to avoid going just in case. I had a Boots urine bottle and a towel and spare briefs for when out in the car,i think I only needed it a couple of times. Standing up from sitting seems to be the most common time to leak along with coughs and sneezing.
A tenna2 pad can hold over 500cc of urine, I had a tenna2 pad inside a snug pair of briefs. I also tested the absorbency of the pad by standing in the shower with a pad in the briefs and let the bladder go.
Stopping mid stream is frowned upon by incontinence nurses but occasionally I would stop mid stream to see how well the sphincter was working.
Hope all goes well
Thanks Chris
