Massive hematuria of nontraumatic renal origin in dogs.
Massive haematuria of nontraumatic renal origin was diagnosed in four dogs. Blood and blood clots were clearly visible in the urine. The dogs were anaemic. Results of coagulation and platelet function tests were within normal limits. Exploratory laparotomy, ventral cystostomy, and urethral catheterization enabled identification of one kidney as the source of bleeding in three dogs. Unilateral nephrectomy and urethrectomy resolved the haematuria in each. Cystoscopy of the 4th dog did not identify haematuria from either ureter. Surgery was not done and the dog continued to have intermittent haematuria. Diagnosis of massive haematuria of renal origin requires the elimination of extrarenal causes of haematuria and the identification of haematuria from one of the ureters.
