Blood in the urine has many causes. This can include cancer, any type of genitourinary infection, a kidney stone, or intrinsic kidney disease.
I would first consider an IVP or cystoscopy as well as urine cytology to exclude to possibility of a mass or cancer causing the symptoms. A kidney ultrasound can be considered to evaluate for any anatomical abnormalities. To rule out stones, a CT scan can be done to rule this out.
If all the tests are negative, I would periodically monitor the urine to see if the bleeding stops or continues. Serial testing with cystoscopy may be considered to screen for cancer.
Followup with your personal physician is essential.
