Has your doc explained as to why the CTs scan differ and from colonoscopy?
(one should have a look at the pics, where diverticulosis was seen and point it out. I really would make the radiologists revisit both CTs and come to a conclusion and correct interpretation.)
Can diverticulosis be a misdiagnosis as not seen in other CT even (I can understand maybe not seen in colonoscopy due to looking for a small hole only, but two different CT reports within samish time frame?)
I would really ask the doc not knowing if diverticulosis was now an issue or not.
Was your 'blood in urine' visible in colour or due to lab result -
if lab: dipstick AND microscopically-whole red blood cells seen?
(You are entitled to a print out of your results)
(Microhematurie - invisible to naked eye, not enough to change colour in urine)
This can be a coincidental finding
and not neccessarily related to the pain. But can be, too, of course.
Many adults have microhematuria without any pain symptoms since 'benign' causes can cause 'blood' to leak into urine.
But need to be checked for sure, repeat urine and then do further tests if positive again and again, to not miss any real underlying cause, that needed treatment.
Infection is one, viral illness another that can cause red blood cells to come out.
Menstruation and vigorous exercise or any urological procedure have to be excluded.
Some taken medication can cause microhematuria (so called medical renal disease), check taken meds for side effects.
Was that all checked?
I would take some multi vitamine capsules or VitC for a few days to get those levels up for sure, since low VitC can cause leakage, but VitC in urine for testing can mask presence of red blood cells.
So yes to vitamine supplement taking, but a no to it 2 days prior sample giving.
If this is all eliminated as a cause and retested positive, the renal function should be checked.
(calculated eGRF, creatinine, and BUN),
cystoscopy is usually then always performed in patients over 35 and no obvious reason found (as mentioned above) for macro or microhematuria.
Multi-phasic computed tomography (CT) urography or MR urography are also possibilities.
It's always the same, if the most common reason is not found (infection), you find yourself with shoulder shrugging and often giving up docs. Duh.
But no, blood in urine is not normal and needs to be checked if false positive
(like exercise) or contamination (like trauma, shaving, menstruation), list any meds in case and go from there, at least reapeat the test if it was just a one off, that has 'healed'.
The urine needs to be fresh, because red blood cells can and will burst depending on osmotic pressure of urine (or shrink, which doesn't matter since still visible as little star cells under microscope).
It is always an estimate because urine can be concentrated or very diluted, hence the cell count per field is highly variable, the number not really relevant, but if seen, it's positive so or so.
All the best!!!!!
(Please don't take a multivitamin capsule prior urine test (VitC is interferring a lot), stay 2 days off additional vitamine supplement intake prior sample please, you don't want to mask it by false neg reaction.)
