Hello dear lybrate-user, hi
Warm welcome to Lybrate.com
I have evaluated your query for your father thoroughly.* There can be possible - urinary tract infection
in the urinary system - tumor in the urinary
tract - side effect of some drugs as aspirin
or else.* Needs evaluation with urologist
for urine microscopy, blood tests, ultrasound
of the KUB, Prostate for final diagnosis and further management. Hope this clears your query. Wishing him fine recovery. Welcome for any further assistance. Regards take care.
