hematuria after proton therapy 4 years

Happens post PT. Known side effect.

Get it checked out, likely it will clear on its own.

Rarely points to anything worse.

I had my urological exam today for the hematuria problem. My urine sample was clear; no blood. The urologist read my recent CT scans of the abdominal and chest taken 2 weeks ago for another problem. He said all were clear and normal. He then decided to do a cystoscopy to look at the uthera, bladder, and prostate. He showed me the screen as he was doing the examine. My first cystoscopy by the way. He said all were very clean and normal. The prostate looked good too he said but did have more after effects of radiation since it was the target. Nothing to indicate cause of bleeding. His differential diagnosis would suggest the prostate since a clot at the end of the urine stream usually comes from the bladder or prostate. The bladder and urethra were pristine so he ruled them out.

My radiation was Proton at UFPTI.

possible: radiation cystitis

It can come and go. Even after years. One of the long term RT SEs.

Also, as my doctor tells me, a little blood can look like a lot when it's in the toilet. Just a drop or two can seem like gallons. Be watchful, but not overly concerned. If it reoccurs, there are a few treatments. But just as likely this will never happen again.
