Hematuria is not ok. This can be the sign of a serious problem. The possibilities include: tumor, infection, stones, enlarged prostate, urinary blockages, or other problems. Sometimes there is nothing detected, but when you can see blood in the urine it should be evaluated because some of the issues this might represent can be very serious.
See urologist. Gross hematuria or visible blood in urine is worrisome and should be evaluated by a medical doctor with likely referral to a urologist.
