Hematuria

Hematuria is the presence of blood in the urine. This happens when your kidneys or other parts of your urinary tract allow blood cells to leak into your urine. Hematuria may be visible to the naked eye or visible only under a microscope and is usually painless.

Although blood in the urine is not always a cause for concern, it may be an indication of an underlying condition in the genitourinary tract that needs further evaluation. The genitourinary tract includes the kidneys, ureters, bladder, and urethra, as well as the prostate/genitals in men.

Symptoms of Hematuria

Depending on the underlying condition associated with the hematuria, you may have the following symptoms:

  • Pink, red, or cola-colored urine. Strenuous physical activity or certain medications may cause bleeding.
  • Pain on your back or the side of your abdomen between the rib and the hip. May be due to a kidney stone or kidney infection, which can cause bleeding.
  • Burning or pain when you urinate, or frequent and urgent urination. May be a sign of a urinary tract infection (UTI) or, in some instances, bladder cancer.

Causes of Hematuria

Many of the causes of hematuria are non-threatening (benign). However, sometimes it may be the only sign of a serious underlying condition. Causes can include:

  • Stones in the urinary tract (kidney, ureter, bladder)
  • Infections of the urinary tract (bladder, kidney, prostate in men)
  • Cancer
  • Kidney disease
  • Kidney injury
  • Inherited disorders
  • Medications
  • Strenuous exercise
  • Trauma

Risk Factors for Hematuria

  • Gender: More than half of all women get a urinary tract infection at least once in their lives, possibly with some urinary bleeding.
  • Recent infection: Kidney inflammation from infection is one of the leading causes of visible urinary blood in children.
  • Family history: You have a family history of kidney disease or kidney stones.
  • Certain medications: Coumadin, aspirin, non-steroidal anti-inflammatory pain relievers, and antibiotics such as penicillin are known to increase the risk of urinary bleeding.
  • Strenuous exercise: Long-distance runners are especially prone to exercise-induced urinary bleeding.
