Ding Qiang, Department of Urology, Shanghai Huashan Hospital: Hello! According to the information you provided, there are two possible causes of hematuria. (1) Prostate source. You have a large prostate volume, with frequent urinary line thinning and bifurcation, consider that there may be prostatic hyperplasia. The other thing I don’t know is whether the burning sensation when you urinate has only recently appeared or has always been there, whether the white blood cells are elevated in the routine urine examination, if so you should consider a urinary tract infection, if not it may be a painful urination caused by prostatitis. It is recommended that you further examine the prostate fluid to clarify whether there is prostatitis; perform urine flow rate measurement to clarify the degree of impact of prostate enlargement on urination. (2) Due to your heavy exercise, you cannot rule out sports hematuria. You can perform a routine urine examination after running, if the hemoglobin in the urine is significantly elevated and can return to normal within 24 hours, then this is more likely. We suggest you consult a nephrologist.
