Hematuria is defined as the presence of blood in the urine. Although dietary pigments (i.e., components of ingested food or drink) or blood from the female reproductive tract can sometimes lend a red tinge to the urine, this should not be confused with true hematuria, which is indicated by blood that has originated with the stream of urine.
Sedentary rabbits, female rabbits, and middle-aged rabbits are all at risk of developing hematuria. This may be due to kidney stones, bacterial bladder infections, and/or an increase of calcium in the blood. The most common cause of hematuria in intact females, however, is the dysfunction of the reproductive tract. Coagulation, clotting disorders, or an injury to the genitals, urinary tract or bladder may also cause blood to develop in the urine.
Your veterinarian will first need to rule out typical causes for red-colored urine, such as a dietary trigger. Also, discolored or brown urine will need to be differentiated from true hematuria. Blood and urine component analysis will be completed and tests will be done to check for the presence of calcium or cancer cells in the blood.
If your doctor suspects the origin of the blood to be from within the bladder, such as from a tumor, or from bladder stones, an endoscopy can be used to visually examine the bladder space. This method uses a small camera that is attached to a flexible tube, and which can be inserted into the actual space to be examined. The endoscope may be inserted into the bladder cavity by way of the urinary tract, using a cystoscope, or it may be inserted through a small incision that is made in the abdomen. In this way, your veterinarian can get a more precise image of any blockages, or injuries, and if indicated, take a tissue sample for biopsy if a tumor is detected.
