Hi, many thanks for the query!
Blood in urine is due to several causes, specifically
in your case it seems to be due to stone in ?
urethra,
Ca-
oxalate stone has spikes on its surface that causes
mechanical trauma to mucosa in
urinary tract causing bleeding.
Also, it can be due to UTI, bladder abnormalities etc.
You need to do- USG KUB, RFT, Urine (R/M), CBC, X-ray KUB.
You haven't mentioned whether this happened for the first time or
how many times till now, also, pain is there or not?
Follow up with your
Urologist with the reports for appropriate management.
Wish you a good health.
Take care.
Regards.
