What is asymptomatic hematuria?

Asymptomatic hematuria refers to the presence of red blood cells in the urine without other urinary symptoms.

Asymptomatic hematuria includes microscopic hematuria, which means that urine examination shows more than 3 red blood cells per high-power field. Asymptomatic hematuria also includes macroscopic hematuria, which can be seen with the naked eye as red or as washed meat, indicating that urine contains more blood. Asymptomatic hematuria may be caused by urogenital diseases, such as urinary tract injury, urinary tract infection, urinary tract stones, etc.
