兩病例於國立台灣大學附設家畜醫院經放射線檢查診斷為犬腎結石,一病例為雙側性腎結石,另一病例為單側性腎結石,二犬皆為雄性且年紀都超過10歲以上。雙側性腎結石其癒後非常差,單側性腎結石其癒後則較好;此情形可由二病例其腎臟功能指數發現:雙側性腎結石其腎臟指數較單側性腎結石為高。在文獻探討方面:犬腎結石為犬之泌尿道系統結石中較為少見的。其嚴重程度及癒後主要依據其腎結石為單側或雙側以及泌尿系統的感染輕重。犬腎結石之診斷須依靠醫學影像學的技術如放射線學、超音波學以及腎孟血管造影術。治療方面則以內科保守治療法以及外科手術如腎結石切除術、腎孟結石切除術及腎臟摘除術。
Two cases of canine nephroliths were diagnosed in National Taiwan University Veterinary Hospital. One case revealed significant two-side nephroliths, another case revealed left-sided nephrolith. The two-sided nephroliths had poor prognosis, but the prognosis in another case was better. The same clinical findings of two cases included age>10 years and male predisposition. On Iiterature review, canine nephrolith is uncommon (<4%) in small animal urolithiasis, largely urolithiasis existed in bladder and urethra. The severity of canine nephroliths depended on the infection of lower urinary tract and kidney involvement, one-side or two-side. The diagnosis of canine nephrolith relied on the medical image: radiography, especially abdominal radiograph, ultrasonography and intravenous pyelogram. The treatment of canine nephroliths can be performed by conservative medical or surgical methods, depended on the composition of urolith, clinical signs and severity of infection and azotemia.
