Blood in Urine Overview

Blood in urine, or hematuria, usually indicates a disorder of the lower urinary system and/or the kidneys. Blood may be visible in the urine with a visual change of color, or in some cases microscopic hematuria may only be detected by diagnostic testing. Blood in urine needs to be distinguished from a simple red or pink color change in the urine (pseudohematuria), and occasionally from other types of bleeding such as vaginal bleeding or rectal bleeding. The many causes of hematuria include bladder disorders (e.g. cystitis, urinary stones), kidney disorders (e.g. kidney stones, kidney infection, nephritis), prostate disorders (e.g. prostatitis), gastrointestinal disorders (e.g. appendicitis) and various other causes. An underlying bleeding disorder is a possible hidden cause. There are many possible causes and this symptom needs prompt medical diagnosis by your doctor.
