Hematuria after Cystoprostatectomy

Hello all, I am a 71 year old male with my bladder & prostate removed in July 2020. I am now considered a survivor. It was not easy journey at first but got better with education and time. Currently I am having blood in my urine 24/7. I initially had no bleeding but had to go on blood thinners. I have all kinds of CT scans and scopes. I was off blood thinners for 2 months but I still bled. I have stumped my Fox Chase Urologist/Oncologist, Hematologist/Oncologist, and my primary physician. I was hoping for some help from someone with a similar condition. The only thing I am confident with is the blood thinners are not the cause but they did exasperated the problem. Thank you in advance. Joe
