Hematuria in rabbits.
A nine year retrospective study of hematuria in 14 New Zealand White rabbits was conducted to classify possible etiologies of this clinical finding. Physical examination, laboratory tests, radiography and postmortem examination were utilized in most cases to verify the presence of hematuria and to determine its etiology. Uterine adenocarcinoma was diagnosed in two rabbits. Three rabbits had uterine polyps with hemorrhage. Renal infarction with hemorrhage was diagnosed in three rabbits. Urolithiasis with secondary urethral obstruction and hemorrhagic cystitis was identified as the cause of hematuria in four rabbits. Other causes of hematuria included chronic cystitis, disseminated intravascular coagulation, bladder polyps and pyelonephritis. Hematuria of undetermined origin was observed in one rabbit. This last [corrected] case was negative for both blood and porphyrin in the urine, but positive for excess levels of urobilin, the oxidative product of urobilinogen. This case illustrates that hyperpigmented urine should be a rule out in all cases of suspected hematuria in rabbits.
