I'm not as far as you in being post-op so I guess you'd be experiencing it (like others in this thread) a little different to me!!!
I get the feeling it becomes a little looser with time? ...so it discharges more readily/quicker? I think mine still discharges slowly and over time and maybe not every bit comes out before I next dilate, even after douching. I don't think my douche reaches up to the end, it goes in about five inches and I squeeze hard but I don't think it flushes all the way up due to the muscles moving back in more. though saying that you're not meant to be douching after every dilation after around six months?
I'm also sussing out how to use less lube so there is less of a mess, I don't need to use a new bed matt with each session now. I find that only putting lube on the first three inches of the stent then going in for the opening, then pulling it out and reapplying a little more helps to not push it off all in one go as it used to.. the pulling it out helps it to lube the first muscle and deposit right in front of it so next push you push some of it inside. The excess lube around the opening covers the stent enough for between 5inches and beyond for me, plus for me the last two inches hardly go in due to swelling! 0___0 I also use a mix of QC and sliky, but I'm a little fussy at the moment due to pain >__< One is really thick and sticks to the stent more and the other is more watery and I put that over the top.. not sure if it really helps but ....maybe psychologically

In the future I
may just use silky as I doubt I need as much to get the same result, it seems to just glide instead of being a bit thick and gooey like QC and KY. Though it may run out down my butt faster :/
I use kitchen paper to wipe once I'm done then wedge a folded kitchen paper wipe between my butt to get me to the bathroom and catch the first dribble load then in the bath I run the warm/hot water and wee >__< then douche then use the little yellow dish to run water over then wash with my hand with hibescrub as I still have some (but will just use liquid shower soap once I run out) to wash, just inside the opening then a sanitary pad with another folded kitchen paper wipe over that until I have my first wee again. It catches most of the discharge and gets me through until I next dilate (which right now is only six hours or over night).
I guess being 10 months you'll only be ...once a day? Maybe try the kitchen paper folded, even two sheets folded if it's a lot.. I find I can (safely) make a pad last 24hrs doing this, unless it leaks through to the pad and makes a mess but rarely does at this stage. >___<
