I leaked badly - had to use an adjustable Depends over the cath to keep from soaking everything. I was also having bladder spasms, which contributed to the leaks. Because of timing of the cath removal, and a lack of having anyone to take me to the doc short of calling an ambulance, I toughed it out, so to speak.
Uro said he agreed it was unpleasant, but short of adjusting the cath, and possibly making it worse, there wasn't much to do.
Keep the tube clean from the urine buildup, as that does raise the possiblities of a urinary tract infection.
In the phase you are in now, if you have any issues/questions, call the surgeon's office and ask. Better to be a bother to them than to ignore something that may turn out to be important.
