A couple of quick observations. Yes, I misread 2017/April as 2018. You still simply do not know what you are facing until you hopefully get to a top notch facility that sees a LOT of bladder cancer. In so many the prostate is the focus as they dwarf bladder issues. Most people adapt and do quite well with any of the 3 diversions they choose. It does sound like your URO's expertise is just the urostomy bag as that is his/her push. Whoever and whatever diversion you end up with that surgeon needs to have seen and done MANY of these. I would want one that has done at least 75-100 or at least 2 years worth. I am bookmarking a wonderful site explaining the pros and cons of each diversion. See:
my.clevelandclinic.org/health/treatments/12546-urinary-reconstruction--diversion.
While blood clots are not good to see I have learned too many times not to speculate. Especially as none of us are doctors and every patient is different. One day at a time! The one thing for sure, get working on this Monday! Ask away as you have more questions.
