Also be evaluated for kidney stones and other causes of blood in the urine. An ultrasound or stone protocol CT scan may be needed as well as bloodwork to check kidney function. ...Read more

Hopefully a urine culture was sent, which will confirm the diagnosis. Blood in the urinary tract should be evaluated, however, and I recommend seeing a urologist who can perform a full evaluation with history, physical exam, and urine testing. ...Read more

Burning during urination for 3-4 days. Went to doctor. Blood in urine no longer detectable visually. Red and white blood cells detected during preliminary urine analysis. Received ciprofloxacin to treat a potential UTI. Doctor did not do a physical exami
