Blood in Urine

Introduction
Blood in urine is referred to as hematuria. Gross hematuria is blood in the urine that can be visualized, and microscopic hematuria is seen only under the microscope. Both of these conditions could indicate a problem in the urinary tract.

Symptoms
Common causes of blood in the urine include urinary tract infections, bladder stones, kidney stones, tumors in the urinary system, kidney disease, and trauma.

Diagnosis
An evaluation of blood in the urine is recommended. The entire urinary tract must be evaluated including the kidneys, the ureters, the bladder, and the urethera. The kidneys produce urine, which is then transported to the bladder via the ureters. The bladder stores urine and finally passes out of the body through the urethera.

An evaluation of blood in the urine includes looking at the urine under the microscope and assessing for abnormal cells in the urine. In addition, images of the kidneys and ureters are obtained. These images may be obtained with a CT scan, MRI, ultrasound of the kidney, or dye injected into the ureters. Finally, a procedure in the office called a cystoscopy looks directly into the bladder.
