Hi and welcome to Chat Doctor. There is tiny chance of it at his age. It can be related to kidney damage due to therapy, but most often causes of hematuria are urinary infections, kidney stones and urethral and kidney trauma which can be minor. He should just do urogenital ultrasound, kidney function test and often do urinalysis to see is there any improvement. Wish you good health.
