Ha. Thinking I'm gonna keep my bladder as long as possible.
The "mass" was removed Thursday. It was about 2cm on the cat scan but in reality was mostly a blood clot and tissue according to the pathological report. My bladder was "distended", being closer to a 2 liter than normal. Pissing is now an extreme sport, hopefully for the short term.
Good luck on your recovery. After the diagnoses, the recovery should be a breeze.
