I am not used to looking at images of the bladder either, the heart is further forwards!! Getting my excuses in early 🙂
It appears that there is normal contrast within the urethra to the level of the prostate. At the prostate you have an odd pattern of accumulation of contrast and there is a small stream of contrast that enters the bladder, but this is less well opacified than the prostate/ urethra. There also appears to be contrast uptake within a tubular structure that moves cranially from the prostate. I am not sure what this is, I initially thought it was the descending aorta, but that doesn’t makes sense. Is there some sort of fistula to bowel/ venous system?
