I've had blood in my urine for a week. It's okay if I don't run, but when I do run, I get blood in my urine.

Patient's question:

Male, healthy before the age of 20, now has symptoms of blood in urine, more pronounced when running, and has been going on for a week.

Doctor's answer:

Based on the patient's condition, it is primarily necessary to consider the possibility of kidney stones. Second, it is necessary to consider urinary system diseases. Further examination and treatment should be conducted using color Doppler ultrasound.
