hematuria

 [he″mah-tu´re-ah]
the discharge of blood in the urine, making the urine either slightly blood-tinged, grossly bloody, or a smoky brown color. Microscopic examination of a urine specimen can reveal red blood cells not evident to the naked eye; however, this microscopic hematuria is not always pathognomonic. Gross hematuria that is visible to the naked eye is symptomatic of disease or injury to a part of the urinary system. Bladder tumors, cystitis, urethritis, and small kidney stones passing along the ureter can cause blood in the urine. Vascular diseases, some types of kidney disorders, and (sometimes but not always) traumatic injury to the kidney can also produce hematuria.
Patient Care. Assessment activities include noting and recording the amount of urine and color and the presence or absence of clots and bits of tissue. Moreover, the patient should be asked at what point during urination the blood is noticed. This information can help locate the site of the source of bleeding. If bright red blood is noticed at the onset of urination, it is likely that the problem is somewhere in the urethra. If blood is noticed at the end of urination, the site probably is near the neck of the bladder. Bleeding throughout voiding indicates that blood is coming from a site above the bladder neck and has been well mixed with urine in the bladder before elimination. Blood that has remained in the urinary tract long enough to deteriorate will give the urine a smoky, brownish color.

Additional information includes any pain or burning associated with urination, as well as pain in the region of the bladder or over the kidney. Hematuria not associated with pain is characteristic of neoplasms of the kidney or bladder in the early stages.

False hematuria or pseudohematuria is a reddish color to the urine that is not associated with presence of blood. Patients taking pyrvinium pamoate (Povan) or Pyridium should be told that their urine will have a red, red-brown, or red-orange color, so that they will not think this is hematuria.
