Massive hematuria of renal origin was diagnosed in 4 dogs. In all dogs, blood and blood clots were clearly visible in the urine. Serum urea nitrogen and urine concentrating ability were normal. All dogs were anemic, and results of coagulation and platelet function tests were within normal limits. Excretory urography indicated hydroureter and hydronephrosis in all dogs, with filling defects in the bladder attributable to large blood clots in 2 dogs. Cystotomy and catheterization of the ureters enabled identification of one kidney as the source of bleeding in 3 dogs. Unilateral nephrectomy and ureterectomy resolved their hematuria. The results of histologic examination were normal in 2 dogs. The 3rd dog had evidence of pyelitis. Cystoscopy of the 4th dog did not reveal hematuria from either ureter. The dog was not operated on and it continued to have intermittent hematuria.
4只犬被诊断为肾源性大量血尿。所有犬的尿液中均可见明显的血液和血凝块。血清尿素氮和尿液浓缩能力正常。所有犬均贫血，凝血和血小板功能测试结果均在正常范围内。排泄性尿路造影显示所有犬均有输尿管积水和肾积水，2只犬的膀胱内有充盈缺损，归因于大的血凝块。膀胱切开术和输尿管插管使3只犬能够确定一个肾脏为出血来源。单侧肾切除术和输尿管切除术解决了它们的血尿问题。2只犬的组织学检查结果正常。第3只犬有肾盂炎的证据。第4只犬的膀胱镜检查未发现来自任何一侧输尿管的血尿。这只犬未接受手术，仍间歇性出现血尿。
