Is blood in the urine a sign of a urinary tract infection?

Each month, Doctor Blond answers your questions in the pages of your magazine. Please note, this information does not replace a medical consultation.

You urinated blood and the problem went away after 3 days of antibiotics. Hematuria (in medical parlance) is often a sign of an infection, as you probably have, or of a lithiasis (a pebble) that “scratches” the urinary tract and causes it to bleed. A fever, pain, a urine dipstick at your family doctor’s office guide further possible explorations. A cytobacteriological examination of the urine confirms the infectious origin.
