DH - Blood in urine - not bladder, kidney or prostate. What is causing it?

[Ohlife2020]

As the title says:

Lots of blood in urine started four weeks ago. Since then, it's not as visible, but still ongoing.

DH has seen the consultant today: ultrasound, cystoscope and PSA screening all clear. A tiny kidney stone unlikely to be the cause. No infection either.

What could this be? I'm desperate searching online and wanting to cry.

I can't unload this in RL to anyone...

Not seeing the consultant isnt necessarily something to be concerned about. He may have seen a junior doctor but they are about to switch to calling them residents as "junior" can mean anything from newly qualified on rotation to someone about to qualify as a consultant after maybe 6 years of specialist training. If it was the only person he saw they are much more likely to be one of the ones in specialist training, the very junior would be supervised at the time. As long as they were not a physician associate...

Many cancers are treatable and are treated quickly. The life limiting but wont kill you can be a long wait.
