In medicine, hematuria, or haematuria, is the presence of red blood cells (erythrocytes) in the urine. It may be idiopathic and/or benign, or it can be a sign that there is a kidney stone or a tumor in the urinary tract (kidneys, ureters, urinary bladder, prostate-(In males only), and urethra), ranging from trivial to lethal. If white blood cells are found in addition to red blood cells, then it is a signal of urinary tract infection.
Occasionally "hemoglobinuria" is used synonymously, although more precisely it refers only to hemoglobin in the urine.

Ultrasound investigation of the renal tract is often used to distinguish between various sources of bleeding. X-rays can be used to identify kidney stones, although CT scanning is more precise.
In older patients, cystoscopy with biopsy of suspected lesions is often employed to investigate for bladder cancer.
If combined with pain, it may be loin pain hematuria syndrome.[1]
