See answer below: Visible blood in the urine (aka gross hematuria) related to a UTI (aka hemorrhagic cystitis) is most often accompanied with other bladder symptoms (urinary urgency, frequency, burning and discomfort) and usually subsides within 24-72 hours IF on the correct antibiotic. Painless hematuria is a red flag and is often related to other causes and deserves further evaluation, even if it is self-limiting
