Theres a blood in my husband urine last night. Then when he woke this morning and pee no more blood in his urine. What is the cause of that urine?

Needs to be checked . Urinary blood in a 52-year-old man must be considered as sign of possible malignancy. He needs to see a urologist. Hopefully will be from a benign cause, but we won't know until he is worked up. Good luck.
